To Compare the Effects of 4 Weeks Low Intensity Intermittent Training (LIIT) and Low Intensity Continuous Training (LICT) on Heart Rate Reserve, Heart Rate Recovery and Physiological Cost Index on College Going Girls

Background and Aim: Exercise strengthens heart muscle, improves blood flow, and lowers blood pressure. This translates to a healthier heart that pumps blood more effectively, recovers faster after exertion, uses oxygen better; reducing risk of heart disease. Exercise intensity is important aspect of enhancing health-related fitness. Aim of the study is to make appropriate prescription of the fitness, obesity, diseased person according to their needs and also see the impact of both type of training. Methods and Materials: Interventional study was conducted on girls of a physiotherapy college, Ahmedabad. Ethical approval was taken. 14 girls were randomly divided into 2 groups (LIIT and LICT), Protocol of 42 min was completed on treadmill for 4 weeks (5 days/week). Training was done at 50–70% maximal heart rate, 11-13 RPE with Talk test. In both group 5 min of warm-up and cool-down period was given. In LIIT, 4 sets with 4 minute of interval (32min), in LICT continuous walking/jogging (32 min) was done. Unpaired t test was applied between outcomes. Statistical analysis was done using SPSS. Result: 7 girls with mean age of (20.5714+1.718) years were included in intermittent training, 7 girls with mean age of (22=2.160) years were included in continuous training, there was significant difference between HRr but no significant difference between HRR and PCI of both the groups. Conclusion: Present study concluded that intermittent training is better than continuous training on heart rate reserve, heart rate recovery and physiological cost index on college going girls.
