Effect of Eight Week Physical Training on Isokinetic Strength and Aerobic Capacity in Indian NCC Personnel

Abstract

Objectives: The objectives of the present study were to estimate the physical fitness parameters such as Isokinetic strength and aerobic capacity of 80 randomly selected Indian NCC cadets aged 15-25 years and to search their correlations with selected physical fitness variables studied. Methods: To serve these purposes, three anthropometric variables such as, height, weight, BMI, five Isokinetic strength measurements (both in extension and flexion), such as peak torque, peak angle, cycle time and maximum power of knee, ratio of peak torque in flexion and extension, and six aerobic capacity measurements, such as, VO₂ max, VCO₂, respiratory exchange ratio, ventilatory equivalent, maximum heart rate and time of treadmill running were measured on all the subjects. Results: Peak torque and maximum power flexion and extension were increased significantly (p 0.001) in the Indian NCC cadets before and after eight weeks training. The ratio of the extension and flexion peak torque were also increased significantly (p 0.05). The endurance was improved significantly with VO₂ max (p 0.001) and time of running (p 0.001) among them. Significant improvement was observed in respiratory exchange ratio (p 0.001) and ventilatory equivalent (p 0.01). Conclusion: It was found that the strength and endurance had significantly advantageous changes after eight weeks of training (in NCC camp). Hence it may be concluded from the present study that the NCC training induces beneficial and significant improvement in the physical fitness components of their cadets.
