Intense exercise induces increased blood neutrophil counts and decreased lymphocyte counts, leads to inflammation immunosuppression. It was previously reported that cystine theanine (CT) supplementation by long-distance runners before a training camp suppressed the changes of these parameters observed in un-supplemented control subjects after camp. The purpose present study determine effects CT on inflammatory response immune state intense endurance at camp.Sixteen were allocated one two...

Individual amino acid supplementation has been proposed to affect various types of athletic performance. However, little information on combinations acids is currently available. This study evaluated an supplement that contained L-leucine (540 mg), L-isoleucine (430 L-valine (360 L-glutamine (650 and L-arginine (610 mg) total 3.6 g per dose. The effects this mixture (AAmix) were in 23 elite male rugby players during year-round intensive training. Athletes consumed the AAmix twice daily after...

The ability to accurately measure resting energy expenditure (REE) is essential in both the study of exercise science and human nutrition. Harris Benedict equation (HBEq) commonly used by nutritionists estimate REE when developing weight loss programs. Relatively inexpensive portable indirect calorimeters for estimating have been developed which oxygen consumption but caloric rely on Weir assumes a respiratory exchange ratio 0.85. PURPOSE: compare measurements using Body Gem (MicroLife,...

Prolonged periods of intense endurance exercise training are often accompanied by an increased inflammatory response and immunosuppression. This effect has been reported to increase susceptibility respiratory system viral infections. A recent trial in mice elderly humans indicated that oral administration the amino acids, cystine theanine (CT), reinforces humoral immune after antigen stimulation. However, actions effects CT on athletes have not previously. PURPOSE: To determine...

The diet recommended in Zone by B. Sears uses an exchange type system with 3 lists of foods: high protein (PRO), carbohydrate(CHO), and fat (FAT). Serving sizes, referred to as “blocks,” are theoretically set so that one PRO block = 7 g PRO, CHO 9 CHO, FAT 1.5 FAT. To follow the diet, equal numbers blocks must be consumed, providing 30% 40% (as% energy intake). Computer analysis (Food Processor Plus, ESHA Research) foods Appendix C book indicates following results a approximately 35, 34, 31%...

1141 Muoio et al. ( MSSE 26, 81-88, 1994) reported that a fat-rich diet improved VO2max and time-to-exhaustion (TEx) in male athletes. This study used similar dietary treatments counter-balanced order. Subjects were five highly trained female triathletes (mean ± SEM, 28.4 1.5 yrs, 61.2 kgs, 172.2 2.7 cm). The percent of energy from CHO, fat protein 67/19/13, 50/38/12 73/15/12 for their normal (N), (F), high CHO (C) diets. consumed the two experimental diets (F C) 7 days prior to testing. TEx...
