Optimal physiological and cardiovascular characteristics are essential for optimal physical performance. Different types of training regimes affect these characteristics and lead to trainee's adaptation and changes in relevant parameters. In present interventional study we have evaluated effects of six weeks sprint-strength & agility training on such parameters. Twenty four young Indian national hockey players volunteered for this study. BW(weight), BMI, BF (%body fat), LBM (lean body mass), rHR (resting heart rate), rBP (blood pressure), rDP (double-product), P/power (using Running-based Anaerobic Sprint Test), VJ (vertical jump), SP (seated shot-put test), BS (ball-hitting speed), Tm (505-agility test) & VO2max were measured, and changes (d) after specified training regime were studied. The training proved to be 'short yet effective'. Significant improvements after training were found in body composition, cardiovascular, aerobic, anaerobic, strength, agility and performance related parameters; but not in BW, BMI, P/LBM, SP/LBM & VO2max/LBM. dVJ was associated with dTm; dSP with dVO2max which also related with drHR, drBP & drDP. dBS was more among those with lower initial BW, BMI & BF. dBS, along with dVO2max/LBM, was more mainly among those with lower initial anaerobic-aerobic fitness. The findings will be useful for coaches, sports managers, players and also for general population for better, individual and/or sport based designing of short yet effective training programs and monitoring of outcomes. Specific physiological parameter improvement targeted training can also be designed based on this research.
