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 in
μF than the other positions in men's lacrosse.
