Abstract
We investigated and compared isokinetic strength, anaerobic and intermittent capacity of men's lacrosse players at various playing positions. The subjects were 33 men's lacrosse players (attacker; ATn=11, defender; DFn=10, midfielder; MFn=12). Measurements contained physical characteristics, isokinetic strength, anaerobic capacity (maximal anaerobic power; Pmax, Wingate anaerobic power; WAnP), and 10-s (R10IC) and 20-s (R20IC) rest intervals of intermittent capacity. Knee flexor strength at angular velocities of 60°/s and 180°/s was significantly greater in DF players than in AT players (p < 0.05), 300°/s was significantly higher in MF players than in AT players (p <0.05). With regard to Pmax, MF players showed significantly higher values compared with AT players (p< 0.05), and WAnP of MF players showed significantly higher values compared with that of AT and DF players (AT; p < 0.01, DF; p < 0.05). R10IC was significantly higher in MF players than in both AT and DF players (AT: p < 0.05, DF: p< 0.05), whereas R20IC was significantly higher in MF players than in AT players (p< 0.05). These results indicate that knee flexor strength, anaerobic capacity, and intermittent capacity are greater inμF than the other positions in men's lacrosse.
