Abdul Kalam College Of Physiotherapy,Pravara Institute Of Medical Sciences,Loni, Maharashtra. India) Abstract: There is increase in physical inactivity. Lack of time is been the most common reason for physical inactivity. High intensity interval training (HIIT) is the most time efficient exercise strategy. But HIIT involves high negative affect and high Rate of perceived exertion. Music is thought to affect senses allowing the separation of thought from feeling, thereby altering ones perception of unpleasant feeling. The purpose of this study was to find the effect of music on perceived exertion, enjoyment, mood and affect during high intensity interval training.30 participants were selected as per the inclusion and exclusion criteria. They were divided into 2 groups: group A performed with music and group B performed without music condition HIIT. To control for order effects, trial order was counterbalanced. Mood was assessed pre and post using Abbreviated Profile Of Mood State (POMS ), RPE and affect were taken over time using the Borg CR-10 scale and the Feeling scale respectively , enjoyment was assessed post HIIT using the Physical Activity Enjoyment Scale (PACES ) . From the present study it was concluded that music had positive effect on enjoyment , affect and rate of perceived exertion and has no effect on mood in high intensity interval training exercise when compared to without music conditioned High intensity interval exercise , and thus may increase the exercise adherence to it . Keywords: Affect, Enjoyment, High intensity interval training, Mood, Music, Rate of perceived exertion. --------------------------------------------------------------------------------------------------------------------------------------- Date of Submission: 12-01-2018 Date of acceptance: 29-01-2018 --------------------------------------------------------------------------------------------------------------------------------------- I. Introduction American college of sports medicine (ACSM) defines physical activity as bodily movement that is produced by the contraction of skeletal muscle and that substantially increases energy expenditure. [1] According to the new guidelines stated by ACSM adults aged 18-65 years should continue to accumulate at least 30 minutes of moderate-intensity physical activity 5 days per week (instead of "most days of the week") or engage in 20-minutes of vigorous physical activity 3 days per week. [2] Regular physical activity has significant benefits for health. Physical activity can reduce the risk of cardiovascular diseases, diabetes, colon and breast cancer, and depression , help decrease the risk of a hip or vertebral fracture and help control weight. [1] Despite overwhelming scientific evidence that regular physical activity is effective in the prevention of chronic diseases and premature death, most adults fail to meet even the minimum physical activity guidelines , so it has become a challenge for the public health sector to find effective ways to increase physical activity. The pervasiveness of physical inactivity has become a widespread public health concern. [3] One out of five adults around the world is physically inactive. [4] Physical inactivity has been identified as the fourth leading risk factor for global mortality causing an estimated 3.2 million deaths globally. According to WHO guidelines, Global Health Observatory (GHO) data states “Globally in 2010, 23% of adults aged 18+ years were insufficiently active (men 20% and women 27%).Globally, 81% of school going adolescents aged 11–17 years were insufficiently physically active in 2010, i.e. they did less than 60 minutes of moderate- to vigorous-intensity physical activity daily, as recommended by WHO. Countless studies have been done to find the cause for the lack of physical activity. The most commonly cited reason for not exercising is a „„lack of time‟‟. [5][6] This finding is common ; regardless of age, ethnicity, sex, or health status, people report that a lack of time is the primary reason for their failure to exercise on a regular basis. [7][8][9] Given that lack of time is such a common barrier to exercise participation and there is increasing need of regular physical activity. Physical activity prescription innovations that yield benefits with minimal time commitments represent a potentially valuable approach to increasing population activity levels and population health. In recent studies it has been proven that High Intensity Interval Training (HIIT) is a time efficient strategy. [10] HIIT may help insufficiently active individuals overcome a major barrier to maintaining a physically active lifestyle, that of a perceived lack of time. An added bonus is that from a time: benefit perspective, HIIT may prove to be a good example where less can be more. [11] . this type of training involves repeated bouts of
