Key result
Moderate aerobic exercise reduces resting heart rate by ~4 bpm in female college students.
Why the study?
Obesity is a major global health issue, motivating the evaluation of aerobic exercise on resting heart rate and body composition.
Does an 8-week moderate intensity aerobic exercise protocol improve resting heart rate and body composition in female college students?
RCT (n=40)
Rank order allocation based on baseline resting heart rate
No
Does an 8-week moderate intensity aerobic exercise protocol improve resting heart rate and body composition in female college students?
Absolute Event Rate: 71.55% vs 75.55%
p-value: p=≤0.05
An 8-week moderate intensity aerobic exercise program significantly improves resting heart rate, heart recovery rate, and body composition in female college students.
Supports recommending moderate aerobic exercise to lower resting heart rate in young women; extends RCT evidence to female college students.
Obesity is a global health issue and millions of people around the globe have obesity. Objective: To examine the effect of aerobic exercise on resting heart rate and various parameters of body composition. Methods: It was a randomized controlled trial. The participants of the study included forty (40) volunteer inter collegiate females of Punjab Pakistan. They were randomly categorized into two groups i.e. control group (CG) and experimental group (EG). It was conducted by following the prescribed exercise protocols of eight (08) weeks. A written informed consent was taken from each subject before participation in the study. After completion of the exercise protocols, the pre and post test data were processed through statistical package for social sciences (SPSS, version,25) Results: The RHR of the 40 participants in pretest was (76.37± 5.63) and in posttest was (73.55± 5.51). The HRR of the 40 participants in pretest was (116.70± 4.46) and in posttest was (110.77± 10.00). In respect of resting heart score of EGs in pretest and posttest the data indicate that the score of pretest of RHR (76.35± 3.85) and post of RHR (71.55± 3.45) were significantly different. In respect of resting heart score of control group in pretest and posttest the data indicate that the score of pretest of RHR (76.40± 7.09) and post of RHR (75.55± 6.48) were not significantly different. In the same way, significantly the pretest measurement of HRR (117.30± 5.74), of control group was not different from the posttest measurement of HRR (119.51± 4.65) t19= -1.714, p≤ 0.05. However, the researcher concluded that before the treatment the EG and CG were balanced in body composition, RHR and HRR. Hence the researcher found that there is significant difference between EG and CG in body composition, RHR and HRR after the treatment.Conclusion: Based on analysis, the researcher concluded that aerobic exercise has significant impact on resting heart rate and various parameters of body composition among female exercise performers.

Nawaz et al. (2022) conducted an RCT in Healthy volunteers (n=40). Moderate intensity aerobic exercise vs. Control group was evaluated on Resting Heart Rate (RHR) at 8 weeks (p=≤0.05). An 8-week moderate intensity aerobic exercise program significantly reduced resting heart rate (71.55 vs 75.55) compared to control among female college students.
