ACUTE RESPONSES OF RATE PRESSURE PRODUCT IN SETS OF RESISTANCE EXERCISE
Journal Title: Medicina Sportiva - Year 2014, Vol 18, Issue 1
Abstract
Objective: To compare the acute responses of rate pressure product (RPP) between dynamic and isometric sets of resistance exercise (RE); compare the acute responses of RPP between upper and lower limbs in RE.Methods: Nineteen active men (22.7 ± 2.2 years) attended this study in a random crossover model. In the first day they performed hemodynamic measurements and one maximum repetition tests (1RM) in leg press (LGP) and bench press (BCP) exercises. In the second, third, fourth and fifth days they performed the following tests: LGP isometric, BCP isometric, LGP dynamic and BCP dynamic, respectively. Isometric protocols were conducted in 3 sets of 40 s (1st set: 25% 1RM, 2nd set: 50% 1RM, 3rd set: 75% 1RM) and dynamic protocols in 3 sets of 10 repetitions (1st set: 25% 1RM, 2nd set: 50% 1RM, 3th set: 75% 1RM). The RPP was obtained immediately after each set.Results: A comparison between protocols showed that RPP was higher (P<0.05) in dynamic than in isometric protocol. A comparison between exercises showed that RPP was higher (P<0.05) in LGP than BCP exercise.Conclusions: In similar relative intensities, the acute cardiac responses are influenced by the exercise protocol, since the RPP was higher in the dynamic condition. Furthermore, RPP seems to be related with recruited muscle mass, since that were observed higher values of RPP in exercises for lower limbs.
