This study examined the effects of pre-exercise carbohydrate (CHO) supplementation on anaerobic exercise performance in adolescent males (n =11; 15.0 ± 0.9 yrs). On separate days, subjects consumed either a CHO or a placebo (PL) beverage followed by 2 Wingate anaerobic tests (WAnT) separated with ten by 10-second sprints. Peak (PP), mean power (MP) and fatigue index (FI) were assessed. Venous blood samples were obtained and analyzed for glucose, lactate, insulin, and catecholamines. A trial by time ANOVA (P < 0.05) was used in the analysis. PP and MP tended to be higher (P < 0.09) in CHO versus PL, and MP tended to decline more in CHO (P < 0.06); Fl for the two WAnT were similar. Glucose concentration significantly increased after CHO consumption and then returned to baseline post-exercise, whereas glucose level remained unchanged over time during PL; similarly observed for insulin. Lactate and catecholamine levels significantly increased over time, but a trial difference was only observed in epinephrine. The tendency for PP and MP to be higher in CHO might suggest a potential ergogenic benefit of pre-exercise CHO although the change in MP over time in CHO and the similarity in Fl might suggest otherwise. / School of Physical Education, Sport, and Exercise Science

Individuals with NIDDM and low insulin sensitivity (Si) have altered fuel use, which may appear in NIDDM relatives. Adolescent males, six with NIDDM relatives (POS) and six controls (CON), matched for fitness and fatness, participated. Peak oxygen uptake (V02pea), ventilatory threshold (VT) and body composition were measured. Insulin and glucose values were used for Si estimates. Oxygen consumption (V02) and respiratory exchange ratio (RER) measurements were made at rest and during exercise at 80,100 and 120% of VT for substrate use. No group differences were found in anthropometric data, V02pea, VT or blood measurements, although fat free mass (FFM) tended to be greater in CON. CON tended to use a higher percentage carbohydrate and a lower percentage of fat than POS, but differences were no longer present after normalization to FFM. Trends towards fuel use differences may suggest metabolic abnormalities are present in POS, but further investigation is necessary. / School of Physical Education, Sport, and Exercise Science
