High Intensity Interval Training (HIIT) is a type of exercise that alternates between short bursts of high and low intensity activity. The physical components may be improved very effectively and efficiently with this kind of training. The choice of an effective practice strategy could be very beneficial because boosting an athlete's performance is correlated with improving their physical components. The significance of this study was that HIIT is helpful in increasing strength, endurance and agility. Thus it could be useful for athletes for their physical fitness in less duration as compared to the conventional protocols.

According to researchers knowledge there is lack of sufficient literature on "The Effect Of High Interval Intensity Training On Speed And Explosive Strength In Sprinters." The past trials do not address speed and strength in relation to HIIT and this study will help identify the need to practice this training in order to enhance the skills and athletic performance of sprinters and will uplift their anaerobic fitness.
