This study compared power outputs PO from both the upper body UB and lower body LB Wingate tests of anaerobic power between biathletes and control subjects. Ten biathletes B selected by the British Ski Federation for potential assignment to the British team and 13 control C subjects cranked or pedalled the same Bodyguard ergometer at maximal RPMs for 30s against resistances of 2.94 and 4.41 joulesrevkg body weight BW, respectively. POs were calculated in watts W and expressed as peak power PP, highest 5s interval, mean power MP, the mean for 30s, and power decrease PD, difference between PP and lowest 5s PO divided by time. Absolute PP and MP for both UB and LB did not differ between groups. A comparison of POs made relative to BW showed B to have higher values than C 11.25 vs 10.25 Wkg for LB PP p.01 and 9.21 vs 7.96 Wkg for LB MP p.001. Similar PO relationships were found for the UB where PP and MP values were higher for B than C 7.61 vs 6.76 Wkg p.01 and 6.07 vs 4.95 Wkg p.001, respectively. Concomitantly, PD was lower in B than C for both the UB p.01 and Lb p.001. These data show that significant differences exist in the anaerobic performance of aerobically trained athletes compared to subjects who are not highly trained and that these differences are reflected in the musculature of the Ub as well as the legs.
