Purpose: The purpose of this study is to examine the combined effect of chocolate milk with physical exercise on selected psychological variables among college male students. At this end of the investigation, we tested the effects of commercially-available drinks on Resting heart rate and VO₂ max in afield-based experiment with male participants.

Methods: The study has secured the participation of 45 male participants in total. The physiological factors that were investigated in these studies were resting heart rate and VO₂max. The experimental group-I (PECMG) were encouraged to have chocolate milk following the prescribed exercise, whereas the experimental group II (PEG) was instructed to just perform the required exercise.

Results: Measures of ANCOVA showed there was a significant difference on Resting heart rate and VO₂max score between groups. Among all three groups (PECMG vs PEG vs CG) chocolate milk with physical exercise group shows good improvement.

Conclusion: The impact of chocolate milk on Resting heart rate and VO₂max was more effective. Experiments with more participants and longer experiment days will provide conclusive proof in future studies. Regardless of whether they drink chocolate milk or not, exercise is important for good health. Sports performance is enhanced by exercise and chocolate milk.
