Abstract
This study examines the effect of incremental exercise and EMS on cardio-respiratory factors of overweight men. Materials and Methods: In this research, 20 overweight men (age 29.1 ± 6.08 years, body mass 28.49 ± 1.98 weight per square meter) visited the laboratory in three sessions. In first session, they performed an incremental test until the exchange ratio equal to one, and to determine the aerobic power (VO2max), they performed the test until exhaustion. In the second session, they repeated the same test as the first session, with the difference that during the EMS exercise test, it was with a frequency of 35-75 Hz. In the third session there is only EMS. Cardio-respiratory factors were examined before, during and during 20 minutes of recovery. The statistical analysis of the data was performed using repeated measure of ANOVA analysis of variance at a significance level of p<0.05. Result: significant difference was found in comparing the incremental exercise session with the EMS session and the incremental exercise + EMS session for energy expenditure, pulmonary ventilation, VE/VCO2 ratio, oxygen consumption, and heart rate (p < 0.05).However, there was no significant difference between the session of the incremental exercise + EMS and the incremental exercise for all the research variables in the times before, during exercise and 10-20 minutes of recovery time in overweight men. Also, there was no significant difference observed in blood pressure during the recovery period among the three sessions (p > 0.05). Conclusion: Incremental exercise has an effect on cardiorespiratory factors, and the combined effect of incremental exercise + EMS during activity has a greater impact and faster recovery time.
