The use of Isokinetic testing has been widely utilized by clinicians to evaluate lower extremity strength. Prior research has demonstrated its efficacy and reliability in clinical evaluation of muscular performance. Prior research has also investigated the relationship of anthropometric measurements such as BMI and body fat percentage in determining strength output with the non-athletic populations. However, in a prior study conducted by the authors no correlation between anthropometric measurements and men’s basketball athletes’ isokinetic torque were found.
PURPOSE: To investigate the relationship between the use of common anthropometric measurements and average torque production of the knee extensors measured by isokinetic testing at three angular velocities in a college men’s soccer team.
METHODS: Fifteen healthy male college soccer athletes aged between 18-22 participated. Athletes were screened on standard anthropometric measurements that included: height, weight, and common skinfold measures. The measurements allowed for calculation of BMI, LBMI, lean mass, and body fat percentage. The athletes’ isokinetic strength of extension was measured through three angular velocities of 60, 180 and 300 degrees/sec.
RESULTS: The relationship between LBMI, body fat, lean mass and average peak torques at three angular velocities were analyzed through hierarchal linear regression and produced significant relationship for 180 degrees/sec F=6.67 (3, 11) p=.008 and 300 degrees/sec F = 11.349 (3, 11) p = .001. Further analysis utilizing Pearson’s bivariate correlation found significant inverse correlation between body fat and peak torque produced at 180 and 300 degrees/sec range from -.547 to -.692 p<0.05 and significant positive correlation between lean mass and average peak torque at 180 and 300 degrees/ sec range from .646 - .790 p<0.05
CONCLUSION: The results supported prior research indicating specific anthropometric measurements and isokinetic torque production are related. In this investigation, significant relationships between body fat percentages and lean mass existed between the anthropometric measurements of interest and the muscle torques at two angular velocities. The results suggest that the uses of anthropometric measurements in male soccer athletes are significantly correlated.
