Comparison of Anaerobic Mean and Peak Power Outputs in Preadolescent Boys and Adult Males
نویسندگان
چکیده
Age related differences in anaerobic mean and peak power outputs were examined in 21 preadolescent (Tanner Stage = 1) boys (age 11.1yrs.±0.3) and 23 male adults (age 20.2yrs.±0.6). The investigation protocol included anthropometric measurements (determination of stature, body weight and fat free mass-FFM by bioelectrical impedence analysis) and the 30-s all-out Wingate anaerobic test on a cycle ergometer. Mean power (boys vs. men) absolute values 300.82W ±74.66 vs. 643.97W ±93.54; relative values 7.06W·kg ±1.04 vs. 8.74W·kg ±1.66; relative values per kilogram FFM 8.71W·kgFFM ±1.48 vs. 10.27W·kgFFM ±1.96. Peak power (boys vs. men) absolute values 347.48W±90.75 vs. 755.88W±116.91; relative values 8.16W·kg±1.18 vs. 10.26W·kg±2.84; relative values per kilogram FFM 10.07W·kgFFM±2.14 vs. 12.06W·kgFFM±2.78. The mean and peak power output values found during the Wingate anaerobic test were statistically significantly lower (p<0.05) in preadolescent boys than in adults even when expressed by total (absolute), body mass (relative) or fat free mass unit. These results show that the adolescents' anaerobic power scores are lower than those in adults which arises the question of the effectiveness of strength and endurance training program during this period of growth and maturation.

Carbohydrate (CHO) consumption before anaerobic exercise was studied in 13 adolescent boys (15.2 ± 0.9 yrs). A within subjects design was employed where subjects consumed a 22% CHO or volume-matched placebo (PL) beverage 30-min before anaerobic exercise on two separate days. Exercise consisted of a Wingate Anaerobic Test (WAnT), ten by 10-s-sprints, and a second WAnT. Fatigue index and peak pow...
