Aim: Resistance training with innovative training methods elicits various cardiac and vascular responses. Therefore, the main objective of this research was to investigate the rate pressure product, blood pressure response, and Cardiac Autonomic Function to resistance activity with a training mask and blood flow restriction in young male athletes. Methods: Eleven trained men (average age 29.2 ± 5.7 years and body mass index 25.3 ± 2.7 kg/m²) with a history of resistance training in the past year participated in a three-week randomized, crossover study using three different methods: traditional (control) resistance training (1RM 75%-80%), resistance training with blood flow restriction, and hypoxic masks (1RM 20%-50%). The resistance training consisted of one set of 20 repetitions and three sets of 15 repetitions of leg extension movements. Cardiovascular responses were recorded before, immediately after, and every 5 minutes for 60 minutes. The repeated measures analysis of variance method using SPSS software (version 23) was applied to examine the significance level of p<0.05. Results: Based on the results obtained, each of the three training methods can lead to a significant increase in hemodynamic responses, including heart rate variability and blood pressure, except for diastolic blood pressure, following the activity. This increase was observed immediately after the exercise, but no significant difference was observed between the groups. (p< 0.05). Conclusions: The findings of this study indicate that a single bout of resistance exercise, with or without blood flow restriction and a hypoxia mask, does not result in distinct cardiovascular responses compared to each other. This study also significantly confirms the effectiveness of such exercise methods, showing that low-intensity exercises with restrictions can achieve goals expected from high-intensity exercises.
