The Effect of Calisthenics Training on Estimated VO₂max Values in College Students

Cardiorespiratory fitness (VO₂max) among university students is worryingly low, with more than 50% of students categorized as unfit (<41.7 mL/kg/min). This study was conducted to determine the effect of calisthenic training on estimated VO₂max values using a quasi-experimental study design on 21 male students of the Faculty of Public Health, University of Indonesia from August to October 2024. Subjects were divided into 2 groups: the intervention group (n=10) and the control group (n=11). The intervention group performed treatment in the form of calisthenics exercise for 40 minutes, and the control group received running exercise treatment for 20 minutes, with both exercises done twice a week for 4 consecutive weeks. Body weight, height, body mass index, estimated VO₂max values, body fat percentage, muscle mass, academic stress levels, sleep quality and macronutrient intake data were measured pre-and-post training and were analyzed using independent and dependent t-tests. The results showed a significant (p<0.05) difference in change on the average estimated VO₂max values between the intervention group (3.5 mL/kg/min) and the control group (11.4 mL/kg/min). It can be concluded that the changes in estimated VO₂max values were likely more effective in the running group compared to the calisthenics group.
