ISOKINETIC STRENGTH OF KNEE FLEXOR AND EXTENSOR MUSCLES IN RELATION TO SEX AND SIDE IN NONATHLETIC COLLEGE STUDENTS

Alper Tura, MSci, Aydan Oral, MD (Istanbul University Medical School, Istanbul, Turkey)

 

The purpose of this study was to provide clinicians with descriptive data on the isokinetic strength of knee flexor and extensor muscles in nonathletic college students and to determine sex and side-to-side differences. 19 female and 16 male subjects aged 17 to 25 years were tested on an isokinetic dynamometer by the same investigator. After warm-up, the testing sequence was three consecutive repetitions of reciproal knee contraction at 60°/sec and 180°/sec and twenty repetitions at 240°/sec on the dominant and nondominant sides. Peak torque, total work and average power were the parameters evaluated during isokinetic testing. For statistical analysis, 95% confidence intervals for mean values were calculated and Student's t test or Mann Whitney U test were used for comparisons. Significant differences occurred in isokinetic strength between male and female students (p<0.001), isokinetic torque for both knee flexion and extension being higher at all speeds on both sides in males than in females. As the speed of isokinetic contraction increased, mean peak torque decreased for both sexes. Total work and average power were also statistically significantly greater in males than in females (p<0.001). Comparison of mean peak torque of quadriceps and hamstring muscles between dominant and nondominant limbs revealed no statistically significant differences between sides. In conclusion, in accordance with previous findings our data also show that men generally produce greater peak torque values than women.

Objective: The purpose of this study was to determine the hypertrophy occurred in quadriceps muscle after Oxford and De-Lorme excercises in healthy subjects by the help of computed tomographic area measurement.

Methods: 30 healthy untrained volunteers were randomly selected. All subjects were male and mean age was 19.8±1.54. Subjects were assigned into three groups of 10 people and were exercised for four weeks. The first group took part in Oxford exercise group, the second De-Lorme group and the thirth group was control, did not do any exercise. The computed tomographic sections were taken from the thigh. The CT scan of the thighs were made hallway between the pubic symphisis and the mid-point of patella to calculate total thigh area. Thigh girths at the level of midthigh had been measured up to 20 cm from mid-patella. The evaluations were made before starting exercise and after four week's exercise program.

Results: In Oxford and De-Lorme groups midthigh composition from computerized tomographic scans showed an increase in total quadriceps area. Also increase in quadriceps muscle area were associated with thigh girths.

We concluded that both Oxford and De-Lorme exercises produced significant muscle hypertrophy.

Key words: Oxford, De-Lorme exercise, quadriceps muscle, computed tomography.
