Effect of Trampoline rebound exercises on cardiovascular indices, body mass index, and lipid profile of obese and overweight women

Background: Trampoline rebound is one of the recent interesting exercises. The present study aimed to investigate the effect of six weeks of trampoline rebound exercises on cardiovascular indices, body mass index, and lipid profile of obese and overweight women. Materials and Methods: The statistical population of the present quasi-experimental study consisted of 20 obese and overweight women in Zahedan ( (BMI) ≤27.5 kg/m2), and randomly assigned to two groups of exercise (n=10) and control (n=10). The subjects participated in four 90-min sessions of rebound trampoline exercises for six weeks using a trampoline mat. Physiological, BMI, and lipid parameters were measured in two stages of pre-test and post-test. Data were analyzed in SPSS software (version 21) using independent and dependent t-test, as well as an ANCOVA test. A p-value less than 0.05 was considered statistically significant. Results: The results demonstrated a significant decrease in post-test values ​​of LDL (from 92.90±1.52 to 73.10±3.81), cholesterol (from 182.10±1.96 to 166.30±6.32), triglyceride (from 108.30±1.33 to 95.30±5.35), and body mass index (29.44±1.07 to 27.38±1.02), as well as a significant increase in HDL (from 59.60±2.75 to 77.00± 3.09) and Vo2max (from 45.50±1.31 to 57.80±1.31) in posttest of the training group, compared to their pre-test (P<0.05). Furthermore, there were the same changes in these parameters in the exercise group, compared to the post-test values ​​of the control group (P<0.05). Conclusion: As evidenced by the results of this study, six weeks of trampoline rebound training had beneficial effects on controlling lipid profile, cardiovascular indices, and body mass index of obese and overweight women. This training protocol is suggested to improve these indicators in the same groups with obesity and overweight, especially for the variety of exercises.
