Abstract: The effect of antioxidant supplementation on exercise performance has not been clearly defined in trained or un-trained individuals. The purpose of this investigation was to test the effects of quercetin-resveratrol combination on plasma anti-inflammatory response and exercise performance in untrained men. After baseline cycling performance testing, the subjects (n=8) were supplemented daily with 500gr quercetin and 500 gr resveratrol for 21 days. The complete blood counts, creatinine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), interleukin-6 (IL-6), Neutrophil gelatinase-associated lipocalin (NGAL) and exercise performance parameters were evaluated at baseline, after 21 days of supplementation and 15 days after the end of the study. The maximal aerobic power (POmax) was increased (19%) in the post-supplementation period compare to baseline and washout period. In the post-supplementation period, the time trial score (TTscore), maximal and average speed significantly increased in the 10 km time trial cycling test compare to the baseline level. Importantly, in response to supplementation, the serum IL-6 and N-GAL levels were upregulated post-supplementation and these levels returned to baseline levels at the end of the washout period. These results suggest that dieatary combination of quercetin and resveretrol may act as a potential tool for enhancing exercise performance by regulation IL-6, NGAL level in untrained men.

Abstract: The purpose of this study was to determine the impact of somatic and body composition variables on aerobic capacity among the male college students. Five hundred (250 trained and 250 untrained) young college levels male students (mean age 20.54 years) participated in this study. In order to evaluate the somatotype components (endomorphy, mesomorphy, ectomorphy) and body composition variables (body mass index, % body fat, lean body mass, % skeletal muscle mass, % skeletal mass and body surface area) researcher applied a testing procedure that included measurements of height (cm), body weight (kg), five muscle girths (upper arm, fore arm, chest, thigh and calf) in cm, four bone diameters (humerus, bistyloid, femur and bimalleolus) in cm, and eight skinfolds thickness (triceps, sub-scapular, suprailiac, pectoral, axilla, abdominal, thigh and calf) in mm. Estimation of aerobic capacity through V ̇O2max. Queen College Step Test was administered. A negative correlation was found between the body fat percentage and V ̇O2max. Also a negative correlation was found to V ̇O2max.with body surface area and endomorphy of both trained and untrained groups. The lean body mass, % skeletal muscle mass and mesomorphy components of somatotype have the greatest positive correlations with V ̇O2max.
