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. Keywords: Intensive interval training, biomotor speed, white blood cells, males Introduction Competition should be fought in a true sportsmanship. To ensure this, sportspersons take oath before the start of the competition. But still situation is not improved, as one or the other day we come to know that somebody (athlete) is tested positive for dope test. The motive is common i.e. to attain top performance. But this is not only the path, whereas one can attain top performance through scientific training. There is no doubt that the success of a runners depend upon the ability of a coach or to correctly manipulate and combine different load factors such as intensity, density, volume and recovery. Competitive sport is a war without gunfire and doping. But Lance Armstrong in his interview with Oprah Winfrey which was aired live on January 18, 2013 mentioned that “It was humanly not possible to accomplish such a feat (Seven consecutive victories in Tour de France and bronze medal in 2000 Sydney Olympic) without doping”. Exactly this is not what should be promoted as this is against laws/sportsmanship of any game. This is a blunder and offence as well. If such things will happen then what is the use of strenuous training that an athlete goes under. Keeping sports performance in mind numerous researches have been conducted and many more are in progress. So that competition is fought with true spirit of the game. Sports performance is not only based on the sports training that were practiced in the field but majority of the things depends on the physiological performance of the athlete, for which blood composition is directly responsible. Many chemicals are dissolved in blood and there are many different types of cells suspended within it (Watson, 2005). Blood contains two main constituents: blood cells (which include red blood cells, white blood cells and platelets) and plasma. Blood cells constitute approximately 45% and plasma 55% of the total volume of blood (Watson, 2005). Leucocytes or White blood cells have an important role in the recognition and protection of the body against the invasion of foreign bodies, including microorganisms and cancer cells. There are two main categories of white blood cells: phagocytes and lymphocytes. Lymphocytes mainly initiate and direct the immune response. White blood cells travel throughout the body and can move out of the bloodstream and migrate into different tissues depending on chemical mediators that signal the cells (Ashton, 2007). It is said that intensive training may lead to increase white blood cells. Above statement is supported by the Avloniti et al. (2007) who revealed that the single bout of soccer training at an intensity of 75% of HRmax induced leukocytosis without affecting the lymphocyte count in elite female athletes. Lamina and Okoye (2011) tried to find out the effect of interval training programme on WBC count and cardiovascular parameters in male hypertensive patients. They concluded that a significant effect of eight weeks of interval training (60%-79% HR max reserve) programme of between 45 minutes to 60 minutes programme on VO2max, systolic blood pressure (SBP), diastolic blood pressure (DBP) and White blood corpuscles (WBC) count at p<0.05. However, they further revealed that the VO2max is negatively related to the WBC count (r=0.339) at p<0.01.
