Summary.
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 ±1.04 vs. 8.74W•kg-1 ±1.66; relative values per kilogram FFM 8.71W•kg-1FFM ±1.48 vs. 10.27W•kg-1FFM ±1.96. Peak power (boys vs. men) absolute values 347.48W±90.75 vs. 755.88W±116.91; relative values 8.16W•kg-1±1.18 vs. 10.26W•kg-1±2.84; relative values per kilogram FFM 10.07W•kg-1FFM±2.14 vs. 12.06W•kg-1FFM±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.

POREĐENJE ANAEROBNE PROSEČNE I MAKSIMALNE SNAGE
KOD DEČAKA PREDADOLESCENATA I ODRASLIH MUŠKARACA
Kratak sadržaj:
Uzrasno zavisne razlike u anaerobnoj prosečnoj i maksimalnoj snazi ispitivane su kod 21 dečaka (starosti 11,1 god.±0,3) u preadolescentnom periodu (prvi stadijum po Taneru) i ko 23 odrasla muškarca (starosti 20,2 god±0,6). Protokol istraživanja sastojao se od antropometrijskih merenja (određivanja telesne visine, telesne mase i mase bezmasnog tkiva-MBT metodom analize bioelektrične impendance) i 30-osekundnog maksimalnog Vingejt anaerobnog testa na bicikl-ergometru. Prosečna snaga (dečaci u odnosu na odrasle muškarce) apsolutne vrednosti 300,82W ±74,66 vs. 643,97W ±93,54; relativne vrednosti 7.06W•kg-1 ±1,04 vs. 8,74W•kg-1 ±1,66; relativne vrednosti po kilogramu MBT 8,71W•kg-1FFM ±1,48 vs. 10,27W•kg-1FFM ±1,96. Najveća snaga (dečaci u odnosu na odrasle muškarce) apsolutne vrednosti 347,48W±90,75 vs. 755,88W±116,91; relativne vrednosti 8,16W•kg-1±1,18 vs. 10,26W•kg-1±2,84; relativne vrednosti po kilogramu MBT 10,07W•kg-1FFM±2,14 vs. 12,06W•kg-1FFM±2,78. Prosečna i najveća snaga ispoljene tokom Vingejt anaerobnog testa su statistički značajno manje (p<0,05) kod dečaka u preadolescentnom periodu, u poređenju sa odraslim muškarcima, u apsolutnim i relativnim vrednostima, kao i u relativnim vrednostima izraženim na masu bezmasnog tkiva. Ovi rezultati pokazuju da je anaerobna moć u preadolescentnom periodu manja u odnosu na zrelo doba što otvara pitanje efektivnosti treninga snage i jačine u ovom periodu rasta i razvoja.
