Attenuating Excess Inflammation Athletes who get the required amounts of leucine-rich protein and carbohydrate immediately after exercise turn that crucial time period from a catabolic state to an anabolic state. To help curb excessive inflammation and muscle soreness, researchers have examined various products and ingredients.

In particular, tart cherry juice and ginger fresh or heat treated have been found to decrease eccentric-exercise—induced inflammation and delayed onset muscle soreness. Specific Considerations While recovery nutrition has three primary goals, the manner in which these goals are achieved depends on the type of sport an athlete plays.

Based on sports science research, nutrition recommendations for athletes are divided into two categories: endurance sports and resistance training. A sports dietitian can develop individualized plans for each athlete, keeping in mind that plans may change based on training adaptations, changes in growth and body composition, injuries, illness, and training phase.

We educate them on their postlift needs during their individual nutrition consults. Many eat dinner postpractice at our training table or at the dining hall where a dietitian is available for live plate coaching as well.

Because glucose is the fundamental energy source for the nervous system, a substantial decline in blood glucose results in volitional exhaustion, due to glucose deficiency to the brain.

It appears that the evidence presented in the literature universally supports the concept that the greater the depletion of skeletal muscle glycogen, then the stronger the stimulus to replenish stores upon the cessation of exercise, provided adequate carbohydrate is supplied.

Though most of the evidence presented on glycogen is related to prolonged aerobic exercise, there is evidence that exercise mode may play a role in glycogen replenishment, with eccentric exercise exhibiting significantly longer recovery periods, up to four days post-exercise. Muscle fiber type is another factor implicated in the replenishment of glycogen in athletes, due to the enzymatic capacity of the muscle fiber, with red fiber appearing to be subjected to a greater depletion, but also undergoing repletion at a significantly grater rate.

Though early literature appeared to indicate that the time course of glycogen replenishment after exercise-induced depletion was 48 hours or more, more recent data have controverted this thought.

One study reported that a carbohydrate intake totaling up to grams per day was found to restore muscle glycogen stores to pre-exercise levels within the 22 hours between exercise sessions. The findings of this study were supported by second study in which a carbohydrate intake of kcal resulted in complete resynthesis of glycogen within 24 hours.

There also appears to be a two-hour optimal window immediately after the cessation of exercise for the administration of carbohydrates. Simple carbohydrates appear to be the preferred replacement during this replenishment period. Administration of. There is also some evidence that even smaller loads 28 grams every 15 minutes may induce even greater repletion rates.

Therefore, at least 20 hours are required to recover muscle glycogen stores, even when the diet is optimal. So, athletes working out two times per day should complete one workout at a diminished workload to relieve the reliance on glycogen reserves.

The principle of glycogen resynthesis and supercompensation has great practical implications, not only in athletics, but also within industry for workers who consistently undergo depletion of glycogen stores due to prolonged bouts of exertion, or extended lifting tasks which would be glycolytic in nature; due to the duration, and also the myofibrillar ischemia induced by static contractions.

The classic study by Christensen and Hansen in established the effect of a high carbohydrate diet upon endurance time, and that pre-exercise glycogen levels exerted an influence in time to exhaustion.

Subsequently, it was discovered that if an athlete, after depleting glycogen reserves, consumed a high carbohydrate diet for two to three days prior to an athletic event, there would in fact be higher glycogen levels than prior to exercise.

Therefore, the concentration of muscle and liver glycogen prior to exercise plays an important role in endurance exercise capacity. In exhaustive exercise many studies have observed significant depletion of both liver and muscle glycogen.

It is interesting to recognize that the point of exhaustion seems to occur upon the depletion of liver glycogen. It follows that endurance athletes who maintain a daily regimen of endurance training without glycogen repletion may severely deplete their glycogen reserves.

Glycogen, the major reservoir of carbohydrate in the body, is comprised of long chain polymers of glucose molecules. The body stores approximately grams of glycogen within the muscle and liver for use during exercise. At higher exercise intensities, glycogen becomes the main fuel utilized.

Depletion of liver glycogen has the consequence of diminishing liver glucose output, and blood glucose concentrations accordingly. Because glucose is the fundamental energy source for the nervous system, a substantial decline in blood glucose results in volitional exhaustion, due to glucose deficiency to the brain.
