The purpose of this study was to obtain descriptive statistics on hip strength and flexibility in conditioned male hockey skaters and age matched, male nonskaters. By comparing measurements between the two groups, an awareness of muscle imbalances and flexibility differences at the hip may be established which could be used in preventing related muscular injuries in the game of hockey (i.e. groin strains). Hip abduction/adduction and internal/external rotation strength ratios were measured in 10 skaters and 10 nonskaters utilizing the Cybex isokinetic testing system. Selected speeds for isokinetic testing were 60, 120, and 180 degrees per second. A statistically significant (p<0.05) strength ratio differential at all speeds was identified between the groups for the abduction/adduction tests. A significant speed effect also was identified. The skaters range of motion in the hip adduction and internal rotation patterns was significantly less than the same patterns in the nonskater group. A comparison of hip strength ratios for internal/external rotation was not statistically significant between the groups for any of the speeds tested. Also, no significant difference in hip abduction or external rotation range of motion was observed between the groups. The hockey skaters experienced a higher number of groin injuries but the difference between the groups was not enough to be considered statistically significant. The relationship between hip muscle imbalance, flexibility, and injury was discussed.
