Abstract: Movement patterns in intermittent sports is influenced by change of direction speed\n(CODS) performance (i.e., acceleration and deceleration in short sprints). A crosssectional\nstudy was used to examine if CODS (modified pro agility test) and linear\nsprint (5, 10 and 20 m) correlated with maximal (1RM) unilateral leg strength\n(unilateral Smith machine squat and unilateral leg press) and unilateral standing\nbalance. Twenty youth male college athletes (soccer players n=10, ice-hockey\nplayers n=10, weight 76.8±6.6 kg, height 180.5±5.9 cm, age, 16.6±1.3 years)\nperformed the tests. A significant (P<0.005) moderately strong correlation between\nCODS and normalized unilateral squat strength was found (r = -0.606).\nFurthermore, a significant (P<0.003) moderately strong correlation between CODS\nand normalized unilateral leg press strength were found (r = -0.631). A significant\n(P<0.003, P<0.002, respectively) moderately strong correlation between CODS and\nlinear sprint (10, 20 m) were found (r = -0.629, r = -0.641, respectively).\nNormalized unilateral squat strength had a significant (P<0.015) moderately strong\ncorrelation to 10 m linear sprint (r = -0.534). Normalized unilateral leg press\nstrength had a significant (P<0.006) moderately strong correlation to 10 m linear\nsprint (r = -0.593). Between normalized unilateral squat strength and 20 m linear\nsprint there was a significant (P<0.027) moderately low correlation (r = -0.493).\nThe correlation between normalized unilateral leg press strength and 20 m linear\nsprint was significant (P<0.020) moderately strong (r = -0.514). The findings\nsuggest that unilateral maximal strength testing is a good predictor for CODS and\nlinear sprint for soccer players and ice-hockey players.
