Background: The amount of physical activity (PA) a person engages in directly affects their health-related fitness. Inactivity contributes for around 3.3% of all deaths, making the lack of exercise and sedentary lifestyles among the young generation a current source of concern. To our knowledge, there hasn’t been any research; revealed data on young adults is there which entails the assessment of physical fitness in different PA categories. In perspective of this, the objective of this research was to find out the affect of PA levels on physical fitness in healthy adults.

Methodology: A total of 419 students between the ages of 18 and 25 participated in this cross-sectional survey. The ‘‘Global Physical Activity Questionnaire’’ (GPAQ) was used to evaluate the PA. Their body fat percentage was measured using a skin fold calliper, followed by measurement of VO2max using a gas analyzer and hand grip strength and endurance assessment with the help of a computerized dynamometer. For statistical analysis, Karl Pearson's correlation coefficients and the Anova test were utilized.

Results: PA was positively correlated with VO2 max (r=0.429), and handgrip strength (r=0.408) while negative correlated with body fat % (r=-.315). VO2 max, body fat %, hand Grip strength differs significantly amongst participants having different physical activity levels. (p-value =<0.05)

Conclusion: This research concludes that PA is associated with physical fitness. PA will lead towards a definite improvement in overall physical fitness. With the help of the results of this study, young adults can be motivated for physical fitness.
