The acute hypotensive effect of resistance training performed with machines vs free weights in normotensive men

Abstract

— Aims: To analyze if different resistance training (machine vs free weight) would have different acute hypotensive effect in active and normotensive individuals. Methods: Fifteen male volunteers (39.2±2.5 years) performed two different resistance exercise protocols, one on machinery and one with free weights for the similar muscle groups and volume (sets x repetitions). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at rest and during 60 minutes after the sessions. Results: There was no interaction between (treatments vs time) for SBP (F70, 84 = 0.9445, p = 0.595) and DBP (F70, 84 = 0.5743, p = 0.991). However, significant differences for time for SBP (F14, 84 = 7.058, p = 0.001) and DBP (F14, 84 = 3.296, p = 0.001), and treatment for SBP (F5, 6 = 291.1, p = 0.001) and DBP (F5, 6 = 13.29, p = 0.003) were varified. Conclusion: Our findings indicate that both resistance training (machine or free weight) induce a similar hypotensive response for SBP in normotensive men.
