NUTRITION FOR ATHLETES  


Nutrition key for young athletes after workouts

I witness this so often: young athletes really going for it in a workout, as they hammer a long run or whip through an intense bout on the track. Then, in the hour or so after the session, many of the youngsters drop into one of three categories.
 
Waiting for the shuttle. If practice ends at five o’clock, but parental taxi service doesn’t rev up until mom or pop gets off work, budding track stars may loiter hungrily on campus until nearly sundown.

Hitting the weight room. With the day’s run accomplished, many hardcore athletes head straight to the gym for strength exercises. It’s not uncommon for serious sprinters or middle distance runners to attack ambitious sets of squats or power cleans just minutes after leaving the track. Many young distance runners also come right off the trail and head to the weight room for core strength work, lunges, or circuit training.
 
Flitting off to their next sport. A fair number of young runners are two-sport athletes. This time of year, scores of them will finish a run, then dash off to club soccer, swimming, basketball, or volleyball practice. No doubt, running takes their fitness to a new level for these other sports. However, like those in the two previous categories, these athletes will fare better by paying closer attention to a key element of performance. That element — to paraphrase realtors everywhere — is "nutrition, nutrition, nutrition!"

Specifically, the nutrition issue in each of the above scenarios is the time delay between running and refueling. Substantial research in the past fifteen years demonstrates that replacing calories promptly after exertion optimizes recovery by bolstering the immune system, staving off catabolism (the metabolic breakdown of living tissue in a protein-deprived state), and increasing muscle glycogen storage. The research (published in Medicine & Science in Sports & Exercise, and The Journal of Applied Physiology) shows that by two hours after a tough workout, this nutrition-based recovery opportunity is reduced by 50%. The studies suggest that a smart recovery plan involves immediate post-workout rehydration, combined with at least 400 easily digested calories in a carbohydrate:protein ratio of about 4:1. Smoothies, chocolate milk, bagels, and fortified sports bars and gels are all worth consideration. Anything is better than nothing.

Armed with this knowledge, the savvy young runner (or parent, or coach) will plan ahead, and make a habit of having a "mini-meal" on hand for the crucial minutes following a run, or for the short recess between two major activities. This is a simple way to squeeze more benefit from all that devoted training. Bon Appetit!

Cereal And Milk Is The New Sports Supplement

ScienceDaily (May 15, 2009) — A bowl of whole-grain cereal is as good as a sports drink for recovery after exercise. New research has shown that the readily available and relatively inexpensive breakfast food is as effective as popular, carbohydrate-based "sports drinks."
Exercise physiologist Lynne Kammer, from The University of Texas at Austin, led a group of researchers who investigated the post-exercise physiological effects of the foods. Kammer and her team studied 12 trained cyclists, 8 male and 4 female. In contrast to many sports nutrition studies, however, the exercise protocol was designed to reflect a typical exercise session. After a warm-up period, the subjects cycled for two hours at a comfortable work rate, rather than the more frequently seen test-to-exhaustion.

"Our goal was to compare whole grain cereal plus milk—which are ordinary foods—and sports drinks, after moderate exercise," said Kammer. "We wanted to understand their relative effects on glycogen repletion and muscle protein synthesis for the average individual. We found that glycogen repletion, or the replenishment of immediate muscle fuel, was just as good after whole grain cereal consumption and that some aspects of protein synthesis were actually better".

"Cereal and non-fat milk are a less expensive option than sports drinks. The milk provides a source of easily digestible and high quality protein, which can promote protein synthesis and training adaptations, making this an attractive recovery option for those who refuel at home".
                                           
The researchers concluded that, for amateur athletes and moderately physically active individuals who are trying to keep in shape, popping into the kitchen for a quick bowl of whole-grain cereal with a splash of skimmed milk may be a smarter move than investing in a high-priced sports drink.

Kammer and her colleagues are scientists in the College of Education’s Department of Kinesiology and Health Education. This study was supported by General Mills Bell Institute of Health and Nutrition.
