ABSTRACT Objective: Participation in aerobic exercise generates increased cardiorespiratory fitness, which results in a protective factor for cardiovascular disease and all-cause mortality. Interval training might cause higher increases in cardiorespiratory fitness in comparison with continuous training; nevertheless, current evidence is not conclusive. This study tests the effect of interval training with moderate intensity continuous training on aerobic capacity (V02 max). Method: 40 young healthy subjects were recruited according to inclusion and exclusion criteria and were randomly allocated into a supervised 6 week endurance training program of 3 weekly sessions of either Interval training ( 5 minutes’ bout at 75%-80% HRMax with 2 minutes of active recovery at 40% -50% HRMax) and continuous training (40%- 60% HR Max) of walking on a treadmill for 30 minutes per session. Primary outcome measure was V02max; secondary outcome measure was resting heart rate, resting respiratory rate, blood pressure and Rating of Perceived Exertion. Results: Vo2max (ml/kg/min) improved significantly in both the groups.(P=0.000). There was reduction in resting heart rate, resting respiratory rate and resting blood pressure in both the groups post 6 weeks of training intervention. Rate of perceived exertion was unchanged in both the groups post training intervention. Conclusion: It was observed that both the groups showed significant improvements in aerobic capacity (Vo2max). There was reduction in resting heart rate, resting respiratory rate and resting blood pressure in both the groups post 6 weeks of training intervention. Key Words: Interval training, Continuous training, VO 2 max Corresponding Author: Razia Nagarwala, Sancheti College of Physiotherapy, 12, Thube Park, Shivajinagar, Pune - 411005.

There is an increasing evi- dence of cardiovascular problems in present era, due to which importance of exercise for development of fitness is on rise. There is a slow decline in cardiovascular function with ad- vancing age that is significantly accentuated by a sedentary lifestyle. ACSM has released a physical activity guideline to improve physical fitness. Hence it was recommended that “there should be accumulation of at least 30 minutes of mod- erate activity on most preferably all days of week.” [1] Participation in aerobic exercise develops increased cardi- orespiratory fitness, which protects from cardiovascular morbidity and mortality. Maximal oxygen consumption (VO 2 max) provides a measure of the maximal volume of ox- ygen that the body consumes via the respiratory system and is transported through the bloodstream to be used to release energy in the cell. VO 2 max is currently the best indicator to assess Cardiores- piratory fitness and it is directly related to cardiovascular health, and its improvement has been linked to decreases in risk of death from cardiovascular disease.
