Influência de diferentes movimentos dos membros superiores nas respostas cardiorrespiratórias da corrida em piscina funda

Abstract

The purpose of this study was to analyze the cardiorespiratory responses and the rating of perceived exertion (RPE) during deep water running performed in different cadences (cad) and upper limbs movements (ULM). The sample comprised 12 healthy women (22.3±1 years; 56.3±5.7 kg; 164.2±5.2 cm) that performed the experimental procedure in three sessions. In the first session the corporal measures and maximal effort test were accomplished. In the other sessions aquatic submaximal tests were achieved with the measures of heart rate (HR), oxygen uptake (VO2), ventilation (VE), energetic expenditure (EE) and RPE. Each aquatic session (interval of 48 hours) was randomly performed in one of the different cadences, 60 or 80 bpm, with three randomized tests in deep water running (interval of 20 minutes), each one performed with a specific ULM: resistant (RES), propulsive (PRO) and neutral (NEU). ANOVA two-way was used, with p<0.05 (SPSS v 11.0). It was verified statistically significant difference between the cadences for all variables (HR, VO2, VE, EE and RPE: p<0.001), with the highest values for 80 bpm. Statistically significant differences were observed among ULM, with the highest values for the PRO movement (HR: p=0.031; VO2: p=0.009; VE: p=0.004, EE: p=0.017 and RPE: p=0.004). There was not significant interaction between cadence and ULM for the analyzed variables. Thus, it can be concluded that the use of different ULM in deep water running exerts influence in the cardiorespiratory responses and RPE, as well as the use of different rhythms of execution.
