Abstract Purpose The purpose of this investigation was to assess the changes over vo2 max, resting pulse rate, cardio respiratory endurance and breath holding time by utilizing aerobic dance with different impacts and frequencies. Experimental Design One hundred and twenty males aged between 18 and 24 years served as subjects for test validation. The subjects completed a treadmill test to determine Vo2 max and were assessed for heart rate (HR) response to a bout of aerobic dance. The experimental design used in this study was 2×2 factorial design involving 120 subjects; the study consisted of four experimental groups. Methods Prior to and after exercise changes over Vo2 max, resting Pulse rate, cardio respiratory endurance and breath holding time were assessed for a period of 12 weeks of aerobic dance in different impacts and frequencies. Pre and post experimental baseline testing were also performed. Bench step and Astrand nomogram, bio monitor, cooper's 12 minutes run and walk and breath holding test were used to assess Vo2 max, resting pulse rate, cardio respiratory endurance and breathe holding time respectively. Data analysis was conducted using two way analysis of variance and ‘F’ test. Results Significant changes were observed over vo2 max, resting pulse rate, cardio respiratory endurance and breath holding time due to implemented aerobic dance programme for a period of 12 weeks. Further low impact aerobic dance training for 5 days per week (LIA5DT) produced better changes over vo2 max (0.971 l/kg/ml), resting pulse rate (4.87 B/Min), cardio respiratory endurance (197m), breath holding time (5.23 secs) than LIA3DT, HIA3DT and HIA5DT. This study demonstrated that the low impact aerobic dance training for more number of days a week is a suitable training modality to bring out desirable changes over physiological variables of college men.
