Skinfold measurement for athletic performance -
Skinfold measurements are completed by pinching the skin with a pair of callipers in certain locations on the body. The measurement gained from the callipers estimates the thickness of subcutaneous fat under the skin, from here equations are used to give an estimate of body fat percentage.
Although skinfold testing is inexpensive, fast, and has high reliability if the measurer is experienced, it also has downsides that need to be considered. This method relies on the measurer remaining consistent over time, which due to human error can be difficult.
However, it is achievable, if they are well trained and experienced. ISAK The International Society of the Advancement of Kinanthropometry has developed international standards for measuring anthropometry and is a reliable qualification [CG2] [LT3] to look out for.
This makes sure that the same sites and techniques are used every time. This is crucial, as even measuring just 1 cm out from the first site gives significant differences in the body composition calculations 5. This could be due to the skinfold measures themselves or the variance in the calculations used, or a combination of the two.
This is why practitioner training is crucial for accurate results. A bod pod is an egg-shaped device that you sit inside of. It uses air displacement plethysmograph to measure FM and FFM. Underwater weight is measured while fully submerged in water and expelling all air inside of the lungs.
As bone and muscle have a greater density than water and fat has a lower density than water someone with larger amounts of FFM will weigh more while in water. Underwater weight, out of water weight and the density of the water and residual volume of the lungs is used to calculate body density and estimate FM and FFM.
This technique may be the most accurate, however, it is very unpractical with few places offering the service. Researchers are still comparing these methods to determine which is the most accurate.
It is hard to say as each comes with its pros and cons, and many factors that could be influencing the accuracy. Short answer, No. So now to explain what body fat percentage actually is. When using skinfolds, the sum of up to 8 skinfold measurements is used in specific equations to give the best estimate of your current composition in mm.
BIA and DXA scans, also use equations based on the data from the scans. To start, body fat plays an important role in keeping our bodies functioning and well. Women, in particular, need more body fat. Body fat is also a key source of energy and important hormones.
As mentioned earlier it is important to keep in mind that these calculations are estimates only. Therefore, your body fat percentage is probably not that accurate.
It can be daunting reading into how much body fat you have or being classified into a certain body type. There is too much pressure being put on athletes and now the general population to be a certain skin fold or body fat percentage.
Although this is drastically changing in professional sport, it, unfortunately, is lagging with age group athletes and in the general population. This is why I urge you not to worry about what the numbers say. When discussing body fat percentage, it is important that is not only 1, probably inaccurate, but also 2, it could trigger or lead to other psychological issues in individuals that may already be feeling insecure.
Getting skinfolds or a scan done, can help to track changes made throughout training. These measurements can be good for creating a discussion , and possibly determine if any weight change is predominately muscle gain or if any weight lost is predominately fat loss.
Many coaches and health professionals working with athletes may want to measure body comp for an indication of how their support is working for their athlete. Then, some of you just like having the numbers. That is great, but this is definitely not the only way to measure your progress. It is important to focus on how you and your body are feeling during your training first.
Have you progressed with your training? Are you hitting your performance targets? Are you getting sick or injured often? Is your menstrual cycle regular? These questions are far more important than any number. However, if you are getting body composition measured, remember the following:.
There is some error with whatever method of measuring you decide to use. Your results are a good guide, but they should not be taken as a be all and end-all. The time of day, what you have had to eat and drink can affect your results. It is best to measure at the same time on every occasion and consider eating similar foods prior to being measured.
For those measuring body composition, it is important to know what the person's perception of their body is. If they have body image issues, we advise caution with the language you use.
Changing your diet to alter your body composition may harm your health and performance. This will probably improve your performance beyond any number.

There are a variety of measurements that tell you a lot more information about your body than simple weight measurement does, for example DXA scans, Bod Pods, BIA and surface anthropometry skinfolds. These types of measurements all come with their own unique set of errors and benefits with their estimation of physique.
See the table below for a summary of the accuracy and reliability of different body composition assessments that can be undertaken:. At Precision Athletica, we primarily assess skinfold measurements. Skinfolds are a robust technique that is relatively cheap, convenient and efficient, and does not require any fasting beforehand, compared to other methods which are more expensive and can give variable results based on the time of day, meals eaten and hydration status.
In a skinfolds assessment, 8 anatomically defined sites on the body triceps, subscapular, biceps, iliac crest, supraspinale, abdominal, front thigh and medial calf are marked to then assess subcutaneous fat fat below the surface of the skin using skinfold callipers.
The sites are chosen to account for individual variations in body fat distribution and the results are given as a sum of the 8 sites some sports will only measure 7 sites, leaving out the iliac crest measurement.
Skinfolds only measure subcutaneous fat, not visceral fat, which is the internal fat surrounding organs, however this is not usually an issue for athletes. In general, an increase in skinfolds is associated with an increase in body fat, while decreased skinfolds is associated with a reduction in body fat stores.
Skinfolds are typically assessed in conjunction with your body mass, to offer an insight into changes in both fat and muscle mass i.
increased weight with reduced skinfolds could reflect increased muscle mass. See the table below for an example of how your skinfolds can be interpreted to assess changes in body composition:. As with many types of measurements, there is a margin of error associated with skinfold assessments.
You will be given a sum of your 8 or 7 skinfold sites, but this should also be presented as a range to allow for measurement error. When you have a subsequent skinfold measurement, if your skinfolds sum is not in the range of the previous measurement, then you know there has been a true change in fat mass, however if it falls within that range then it can be viewed that skinfolds have remained stable.
Frequent ongoing measurement of your skinfolds will be a valuable tool in helping you monitor body composition over time.
We recommend every weeks depending on the athlete and sport. When using your body weight to compliment your skinfold assessments, remember to weigh yourself at the same time every time you weigh yourself as weight can be influenced by the time of day or month for females and hydration status lighter if dehydrated.

The answer to this question is multi-faceted and may include pressure from coaches, pressure from Skinfpld athletes themselves, peer pressure, or types of uniforms Sports nutrition guide. Unfortunately in the world Breaking the stigma around eating disorders sports, many people masurement coach sports hold degrees in other Skinflod fields besides kinesiology or athldtic related field.
While the coach may have perfprmance degree of knowledge regarding a specific sport, the coach may Insulin resistance and insulin resistance podcast have a Sknfold enough understanding of basic physiology to understand body composition, weight, and their effects Liver detox diets performance.
This problem athlegic be compounded if the coach measuremfnt has a lack of knowledge about designing and implementing conditioning and weight loss programs for their athletes. Ignorance from coaches can cause an athlete who may be predisposed to eating disorders to start on the path of disordered eating.
Coaches may also not understand the significance of either an off-handed or intentional comment to a female athlete about her weight. Before comments are made to an athlete, significant thought needs to go into the purpose of the comment and the effect it may have on an athlete.
Understanding the complexities of disordered eating and female athletes should be a requirement for all coaches who choose to work with female athletes. For example, because of the negative psychological and physiological effects of mandatory weigh-ins or body fat measurements on female athletes in sports teams, the Canadian Academy of Sports Medicine issued a position statement calling for the abandonment of routine body composition assessment in female athletes.
Mandatory weight limits should also be discontinued. Both of these protocols may lead to extreme dieting in athletes. Even without the assistance of a coach, athletes may apply their own pressure to lose weight because they believe that it may improve performance.
If the athlete has a higher than normal body fat percentage, this may be true. However, for athletes in normal weight ranges, this rationale is not supported by research.
Coaches need to pay attention to athletes who appear to be in a normal weight range but who continue to insist that they need to lose weight. These athletes need to be identified and referred to a professional who can educate them as to what a healthy body weight is and refer them for psychological counseling if warranted.
While sports offer many positive psychological and physiological benefits for athletes, one possible down-side is learned pathological disordered eating behaviors.
Although most athletes are willing to get help for their peers with eating disorders or disordered eating, some may actually assist in teaching the behaviors. Adding extra pressure for female athletes to diet and restrict caloric intake is the focus on the outside appearance of athletes by the uniforms that are worn in some sports.
When athletes are required to wear uniforms that are body tight and expose a lot of skin, athletes may be self-conscious about how they look. For example, female athletes in the sport of basketball and soccer wear uniforms that are loose and baggy. These athletes would not be the ones feeling the pressure of their outward appearance.
Is it possible that the volleyball uniform may place an athlete at risk for disordered eating? This is a question that needs to be asked of the volleyball industry.
Does the current uniform enhance performance? Biomechanically speaking, tight uniforms are worn in other sports i.
Reducing drag does not appear to be a factor in a gym setting. So what purpose does it serve to place these athletes in these uniforms? Other sports require tight fitting uniforms i.
This same thing could be said for dance, competitive cheerleading, and figure skating. It is also these sports that have a higher incidence of eating disorders in their athletes. It is understandable that these athletes are concerned about their body image when they are on display in front of their peers.
However, what needs to be taught to athletes is that athletes come in all shapes and sizes. Some female athletes will have larger and more developed muscles than others. Some athletes may be taller or have broad shoulders.
All of these are genetically determined and cannot be changed by the individual. Athletes who have a healthy body composition need to be taught to embrace themselves and their bodies and become comfortable with the skin they are in.
Educating coaches and athletes about how to achieve a healthy balance between muscle development and body fat composition is a good place to start a discussion.
Talking about the importance of developing muscle mass is as important as talking about the necessity and benefit of a healthy body fat percentage. Athletes need to develop their muscles because stronger muscles tend to correlate with improved performance as long as the motor skill development is there.
This is a good thing and one that needs to be understood by both coaches and athletes. A healthy body fat percentage is also important for the health of a female athlete. Athletes should know the ranges of body fat that are healthy as well as those ranges that are unhealthy.
If an athlete has an unhealthy percentage of body fat, she needs to be counseled by a sports medicine professional as to how to make healthy changes in behavior to modify the percentages. Some athletes will have larger bone structure than others.
An athlete with larger bone structure and greater height will not be able to achieve weight restrictions without compromising her health. Coaches need to understand this factor and not place weight restrictions on their athletes.
Open discussions need to occur within female sports teams about body image and healthy weight management. Talking openly about body image is one way to bring the discussion about the dangers of eating disorders out in the open.
These kinds of discussions may also provide an athlete with an eating disorder the courage to ask for help. Coaches, athletic administrators, and all those who work with female athletes need to understand the link between disordered eating and female athletes and eliminate procedures or protocols that may place an athlete at risk for an eating disorder.

Kinanthropometry techniques have been used for centuries to measure the physique of athletes and other individuals alike and include techniques such as somatotyping, anthropometric techniques, and body composition testing 3. Currently, the Level 3 Anthropometrist course delivered by the International Society for the Advancement of Kinanthropometry ISAK is the highest international standard for kinanthropometry Although the organisation has thousands of members and holds itself to a high standard of excellence, professionals in the field of sports science and strength and conditioning are not legally required to hold an ISAK certification to provide anthropometric services. There are numerous ways to measure body composition, including, but not limited to, body mass index BMI , underwater weighing, dual-energy x-ray absorptiometry DEXA , air-displacement plethysmography, skinfold calipers, or somatotyping. Currently, the absolute gold standard for body composition measurement is cadaver analysis 2, 21 , as no other in-vivo technique will be as accurate as the dissection technique. In living subjects in-vivo , however, DEXA is currently seen as the gold standard. In this article, the advantages and shortcomings of the skinfold calipers as a means of estimating body composition will be thoroughly discussed. Depending on the physiological demands of the sport, anthropometry could be one of the key performance indicators in competition, as it is in sport climbing. Many studies have highlighted the importance of a low percentage of body fat for good climbing performance and therefore is measured routinely in testing batteries In this case, DEXA and skinfolds might be used jointly so that both accurate numbers of actual body fat percentage through DEXA , and more frequent check-ins with an ISAK-certified specialist for skinfolds could be used. Similarly, a key performance indicator for marathon events or long-distance running is a low body fat percentage, which is crucial in planning the yearly periodisation for the athletes in and out of their main competition seasons 4. For an event like the marathon, in which the athletes carry their body weight, having a low body fat percentage, and low total body weight will decrease the energy cost of running, further contributing to their performance Skinfold calipers Figure 1 are one instrument used by anthropometrists specialists that study kinanthropometry to attempt to estimate the amount of fat on a human body. There are many different shapes and prices for skinfold calipers, but ISAK does not specify which caliper types are required, so often what the budget affords are the ones practitioners choose. Harpendens, by contrast, can cost hundreds of dollars, are made of metal, and have a measurement accuracy to the nearest 0. As long as calipers are properly calibrated, then they may be used for estimating body fat By taking a double fold of the skin and underlying subcutaneous fat with the skinfold caliper Figure 2 , practitioners measure various specific sites on the body to estimate the average thickness of each site. With this information, scientists have developed equations that help us estimate the total body fat percentage. Matiegka was the first to develop equations for predicting body fat percentage from skinfold thickness Since then, numerous equations have been developed Though many equations have been developed in an attempt to improve the measurement accuracy of skinfold calipers, the following equations were developed by Siri These equations are just one example of how this can be done, however, other equations are specifically targeted to gender, age group, and other types of populations e. Age is always in years. As skinfold calipers are quick, easy-to-use, and very affordable for estimating body fat percentage, they have become more widely used over the years This has happened despite newer techniques such as DEXA , magnetic resonance imaging MRI , computerized tomography CT , and bioelectrical impedance analysis BIA all having been developed One study by Eston et al. Furthermore, skinfolds tended to under predict body fat percentage as compared to DEXA , revealing that DEXA and skinfold could not be used interchangeably. According to this study, and others 6, 9 , skinfolds may have a significant bias at extremes of body fat and age. The best use of skinfolds seems to be their raw values i. the summation of all measurement sites in millimetres , rather than their ability to predict total body fat percentage because there are errors associated with the accuracy of the collection of the raw data, and error in assumptions in the final values Raw skinfold data can give us a good idea of the regional fatness, unlike other measures like BMI or circumference measures alone 8, For some populations, such as athletic populations, where the difference of one percentage point of body fat can make a difference in performance, skinfolds are likely more important For overweight or obese populations, taking skinfolds may be of less use, as accuracy and reliability of the skinfold measurements will be harder to repeat as the skinfold thickness increases, so methods like DEXA may be more accurate 5. Other studies, for example on obese children, have found good agreeance between skinfolds and percent fat measured by DEXA 22 , however, considerations based on the population being measured must be addressed by each case separately. In anthropometry, technical error of measure TEM is what we refer to the error that occurs when a measurement is taken on the same object more than once, and the values are not the same. This error is inherent especially when humans are involved in the measurements, due to:. We want to minimise the error in our measurement as much as possible to create the most accurate and reliable measurement possible each time, but all errors cannot usually be removed To minimise these factors, it is best that we control as many factors as possible, and use the same tester, the same location, the same time of day and day of the week, and a consistent schedule throughout the week in training and diet Because we know the error is associated with the measurements, practitioners should always express their measures as a value with the technical error, so that when measuring change over time, we can be more certain of real change versus errors made in measuring. To calculate the technical error, use the following equations, outlined in a paper by Perini et al. Table 1. Acceptable levels for intra- and inter-evaluator error, according to a beginner Level 1 ISAK versus a skilful anthropometrist Level 4 ISAK Finally, to make measurements of body composition more accurate, ensure the use of predictive body fat percentage equations that best match the demographic of the persons tested. Generally, the understanding of the use of skinfold calipers and their accuracy is very poor and grossly misunderstood. Given this, our mission was to clarify whether skinfolds are a good method of choice for body composition. In conclusion, skinfold calipers can be a cost-effective, quick, and relatively accurate measure of body composition over time. While the gold standard for body composition is still cadaver dissection, skinfold measurements can offer information about the relative fatness, the change in body composition over time, and potentially even the health of the individual. Knowing that increased fat mass is associated with various diseases, and some athletes need specific body fat percentages for optimal performance, it is of importance that fitness professionals measure skinfolds accurately and with the ability to be repeatable, following the ISAK for best results.

| ORIGINAL RESEARCH article | Ironically, an equation using a mere two skinfold sites abdomen and thigh developed in male nonathletes by Wilmore and Behnke [27] was more closely related with DXA, compared with the other equations developed in athletes. The results of this study differ from those obtained from anthropometric comparisons in other male soccer players. In 45 professional male soccer players from the Premier League [28], a 7-site skinfold equation developed by Withers et al. Recently, Suarez-Arrones et al. With the exception of one equation created by Deurenberg et al. in [31], and BIA via a Tanita device, body fat percentages derived from all skinfold equations had moderate or strong relationships with the body fat percentages derived via DXA [30]. However, the strength of the relationships differed among equations used, with an equation developed in by John Faulkner [32] having the strongest relationship with DXA [29]. The results from these studies demonstrate the lack of agreement between equations, and inconsistent outcomes when compared with more precise body composition assessment methods, such as DXA. As demonstrated by Zemski et al. Substantial intra- and inter-observer variability exists [35, 36]. For example, varying the skinfold site by as little as 1 centimeter can produce significantly different results when experienced practitioners measure the same participant [7, 40]. The research regarding which skinfold equation s most accurately predict body fat percentage in athletes is inconsistent, at best. Factors including age, sport, race, gender, and others, appear to impact equation validity. However, skinfold assessment can also be quite reliable and should be considered as a convenient, practical indicator of intra-individual regional and total body composition change over time. Although 3-site and 7-site skinfold equations are similar in accuracy, I lean towards collecting data on more sites. In the case that a novel, highly accurate equation is developed, the practitioner will be better suited to apply the novel, more accurate equation with his or her data set.

Table 1 shows body composition ranges typical for collegiate student-athletes, based on skinfold caliper analysis. These values should not be taken as recommendations or strict guidelines. Rather, they should be used as a reference point when evaluating body composition results. Every student-athlete is different and the recommended range for any specific individual may or may not fall within the range. Table 2 shows compiled bod pod results from the to NFL combine. Note the variability of body composition by position played and also within each category. For example, running backs averaged As a greater rate of obesity, disordered eating and associated health problems are seen at the collegiate level, appropriate attention must also be paid to interventions for student-athletes above and below their target body composition range. Working with a registered dietitian, particularly a board certified specialist in sports dietetics CSSD to design a nutrition plan is recommended. There are many different methods for evaluating body composition. There is no gold standard since some degree of estimation and error is associated with all methods. Regardless of measurement tool chosen, if any, it is important that student-athletes be educated on the concept of body composition. is extremely valuable. In the collegiate setting, numerous assessment tools are used. Skinfold calipers are common, accessible, inexpensive, and thus, commonly used. The consistency and accuracy of results is highly dependent upon the individual conducting the assessment. Each of these methods has strengths and considerations for student-athletes and testers. See Table 3for more information about various testing methods. Body composition can be very powerful tool for enhancing performance and well-being and tracking changes when careful consideration is made regarding procedures, data interpretation, and communication. Work with a sports RD to establish a body composition protocol that suits your student-athletes and staff. For advice on customizing an eating plan that includes a caffeine dosing protocol that is safe and based on current evidence, consult an RD who specializes in sports, particularly a Board Certified Specialist in Sports Dietetics CSSD.

Written by: Michelle Rockwell, MS, RD, CSSD, Virginia Polytechnic Institute and State University Body composition is a physical measurement that provides more specific information about body make-up than body weight alone. Does body composition impact athletic performance and health? Assessing body composition There are many different methods for evaluating body composition. Assessment tools and methods used with college student-athletes: In the collegiate setting, numerous assessment tools are used. Considerations about body composition analysis: A body composition measurement from one method cannot be compared to one from another. For example, a football player evaluated by DEXA at his university cannot compare results to the BodPod values he receives at the NFL combine. Likewise, when tester or equipment variation comes into play, results also cannot be compared. A cross country runner who has skinfold caliper measurements performed by her strength and conditioning coach cannot compare results to the same measurements taken by the sports dietitian. Measuring via the same method in a systematic way offers the most benefit for individuals and team analysis. Measurements should be done in private. Results should be handled with sensitivity. The National Athletic Trainers Association suggests that body composition results be treated the same as other medical information with regard to confidentiality. Measurements should be taken when student-athletes are well-hydrated and before exercise. In general, measurements should be taken no more frequently than every two to three months. Some professionals recommend twice per year or less. Defer to your sports dietitian regarding specific student-athlete protocols. There should always be a purpose for taking measurement. Clear and consistent communication is paramount. Testers must be sensitive to the impact of assessment on student-athletes. If resources are not available to assist with the management of body composition information and education, its best to avoid it altogether. Communicating about body composition Always emphasize performance measures, overall training, diet and healthy lifestyle as highest priority for athletes. When body composition change is appropriate, establish a percent body fat range rather than an absolute value. Changes in body composition should be gradual and targeted changes are priority in the off-season whenever possible. Guide student-athletes to focus on FFM as much as they focus on percent body fat as this is functional, powerful athletic tissue they wish to maintain or increase and can feel more positive than focusing on decreasing percent body fat. It is recommended that athletics departments develop guidelines and protocol for measurement, analysis and communication of body composition data. Table 3. May feel intrusive to some athletes. |

Additionally, the field 3C model can provide a suitable alternative measure of FFM for both male and female athletes when laboratory-grade criterion measures are not available. The purpose of kinanthropometry is to understand human growth, performance, and nutritional status, especially concerning sports performance. Casciaro, M. BIA devices then utilize regression equations to estimate specific body composition compartments, whereas BIS devices use Cole modeling 8 and mixture theories 9 to estimate body water and other body compartments, of which the latter is often regarded as the more accurate of the two for evaluating body composition parameters 6. |
| Introduction | Whole Body Plethysmography BodPod Air-displacement plethysmography ADP can allow for the calculation of body composition through a 2-compartment model, based on assumptions of value constants for FM and FFM densities. Body weight and body volume are determined by this method, with mass divided by volume providing a measure of density. Again, this measurement is a non-invasive and quick method, with the advantage of not requiring exposure to radiation. BodPod has been shown to be a valid measure of group average body composition when compared to DEXA in female collegiate athletes However, research has suggested a difference of 5. BodPod has also shown limited accuracy when attempting to determine changes over time 13 , a primary consideration when choosing an assessment method for athletes. Body density is determined and then used to estimate body fat percentage. Again, this estimate is based on assumptions regarding the density of FFM, which may vary with age, gender, ethnicity and training status, potentially limiting its use in athletic populations Although this method was previously considered the gold standard by the American College of Sports Medicine, it is not without measurement error. The results are highly reliant on subject performance, and as the process itself is uncomfortable, it may take multiple tests to get a valid measurement. For example, measurement error can occur through unsuccessful attempts to blow all of the air out of the lungs, or air bubbles trapped in hair or swimsuits. Bioelectrical Impedance Analysis BIA BIA is based on the concept that electric current flows through the body at different rates depending on its composition It involves running a light electrical current through the body and determining body composition through the resistance of the tissues to the electrical current. The low cost, speed of measurement and lack of need for technical expertise make BIA an attractive option for body composition measurement, particularly in epidemiological research. However, the accuracy of BIA is dependent on several factors, and as a result, it is likely the least valid measure of body composition discussed in this article. BIA relies on empirical equations to estimate total body water, FFM and body cell mass; these equations use gender, age, weight, height and race as variables. Therefore, for BIA to be used as a valid measure of body composition, the correct equation must be used based on these factors The validity of BIA in some populations has been questioned, particularly in obese patients 18 , and in those with conditions that may alter fluid distribution, such as oedema BIA data is influenced by hydration status, and although the standardisation of fluid intake in the hours before testing may reduce the effects of hydration on body composition measurements, there is a lack of standardisation, or at least its reporting, in current research This may also be true in applied practice with athletic populations. Exercise has been shown to lead to vast inaccuracies in body composition analysis using BIA 21 , as has changes in hydration status As a result, BIA may not be suitable for determining body composition changes due to fluctuations in hydration status following training. Body composition measurement in vivo is an estimate. As mentioned previously, the cost and practicality of measuring body composition vary greatly, and often there is a trade-off between the two. Each method has a use in certain settings, and it is the job of the practitioner or user to understand the benefits and drawbacks of each method. A further issue with body composition is often the focus of individuals on their absolute body fat percentage values. Rather than focusing on an absolute body fat number, it may be of more value to standardise measurement and track changes over time. As measures of body composition are developed, more accurate measurements of FM and FFM can be established in various athletic populations. This means that future research should aim to determine:. There are a multitude of body composition assessment tools available to the practitioner, each with varying cost, accessibility and accuracy in each population. It is important to understand the benefits and limitations of each method, and how best to utilise each one in practice. Most assessment tools are useful in various settings, and accuracy can be improved with proper standardisation prior to testing. Learn how to improve your athletes' agility.
