Comparative analysis of isometric maximum voluntary contraction of knee extensors among different angles


Author(s): Dr. Rahul H Kanojiya

Abstract: The present study was aimed at comparative analysis of isometric contraction (eccentric) of knee extensors among different angle. The study was conducted on 18 male from Hockey Match Practice LNIPE, Gwalior age ranging from 23-30 with mean and SD of age 26±2.1 years, 173.56±6.00 cm and 68.56± 5.46 kg (as data were normally distributed). Data were collected on isometric maximum voluntary contraction (MVC) of knee extensors in 60o, 90o and 120o angle with the help of Humac Norm isokinetic dynamometer. All the subjects were tested repeatedly on isometric contraction (eccentric) of knee first in 60o, 90o and 120o. The test was consisted of 5 seconds maximum voluntary contraction for 5 reps in each angle. It was hypothesized that there would be significant difference of among different angles on peak torque, average torque, peak torque slope. One-way repeated measure ANOVA was employed for the analysis of result at 5% level of significance. Finally, significant difference (p>0.05) was found in peak torque among different angles. Peak torque was found significantly higher (p>0.05) in 60o (105.80±13.69 N-m) than 90o (89.87±13.52 N-m) and 120o (75.07±12.08 N-m).Thus, it can be concluded that Maximum Voluntary Contraction (MVC) or peak torque varies in different angle of knee extensors due to force- muscle length (F-L) relationship and the muscle fibres involvement.
