Effect of intensive interval training on biomotor speed and white blood cells of males

Satish Sharma, Dalwinder Singh


Abstract:The present study was conducted to find out the effect of intensive interval training on biomotor speed and white blood cells (WBC’s) of males. Fifty (N=50) healthy male students of Lovely Professional University, Phagwara, Punjab were selected through equated group design. Further, they were randomly assigned to experimental (n=25) and control (n=25) groups. The experimental group had participated in the twelve weeks intensive interval training, having an intensity of 80%-90% with recovery of 90 to 180 seconds whereas control group did not participate in intensive interval training programme. To ensure the uniform testing conditions, the subjects were tested during evening hours only. For measuring the speed of subjects, the 50 yard dash was organised. The blood samples of subjects were analysed to get the actual white blood cells counts. Training intensity was established by using the Karvonen formula. The‘t’-test was applied to find out the significant differences in mean scores (pre-test and post-test) with regard to the experimental and control groups on the variables; biomotor speed and white blood cells. For testing the hypothesis, the level of significance was set at 0.05. It is concluded from the results that significant difference has been observed in experimental group on the variable of speed whereas insignificant difference has been found on the variable of white blood cells. However, insignificant differences had been noticed in control group on the said variables. Therefore, it is safely surmised that to increase the biomotor speed, the intensive interval training method can be used.
