Anaerobic and aerobic components during arm-crank exercise in sprint and middle-distance swimmers



Anaerobic and aerobic components during arm-crank exercise in sprint and middle-distance swimmers



European Journal Of Applied Physiology & Occupational Physiology. 66(5): 461-466



The purpose of this investigation was to compare anaerobic and aerobic components measured during arm exercise in sprint and middle-distance swimmers and to investigate whether the peak anaerobic power:peak aerobic power ratio (W-an,peak:W-aer,peak) was related to specialization for the event and to performance. The W-an,peak, force at zero velocity (F-0), and velocity at zero-force (v-0), W-aer,peak, peak oxygen uptake ( ovrhdot VO-2peak), and ventilatory threshold (Th-V) were compared during arm exercise tests in sprint (group I, n = 8) and middle-distance (group II, n = 9) competitive male swimmers. Anaerobic indices were estimated by the force-velocity test, an anaerobic test using incremental braking forces; aerobic indices were measured during an incremental aerobic exercise test (30 W cntdot min-1). The W-an,peak and W-aer,peak were greater in group I (828 (SEM 70) W; 236 (SEM 12) W) than in group II (678 (SEM 28) W; 230 (SEM 5) W), but the differences were not significant. There were also no significant differences observed between the mean values of F-0, v-0, ovrhdot VO-2peak, and Th-V. The W-an,peak:W-aer,peak, however, was significantly higher in sprint swimmers (t = 3.08, P lt 0.01). In seven of the swimmers, who had recently performed both the 100-m and 400-m front crawl, a relationship existed between their swim time and the W-an,peak:W-aer,peak (100 m: r = -0.80, P lt 0.05 and 400 m: r = +0.75, P lt 0.05). In conclusion, during arm-crank exercise, we did not observe significant differences in anaerobic and aerobic components between sprint and middle-distance swimmers. However, the results of the present study demonstrated the usefulness of the W-an,peak:W-aer,peak in the physiological evaluation of swimmers as it reflects the proportion of anaerobic to aerobic systems involved in the supply of energy.
