Acute recovery of heart rate in a functional fitness session and its relationship with maximum oxygen consumption
Abstract
Foundation: the recovery heart rate in physical efforts is a relevant indicator for health and sports professionals.Objective: to relate the acute recovery of the heart rate in a submaximal functional fitness session with the maximum oxygen consumption in physically active subjects.Methods: descriptive study with a quantitative approach with a convenience sample made up of 14 men (age 21.32±4.36 years; body mass 71.42±14.68 kg; height 1.75±0.17 m; BMI 23 01±3.61 kg/m2) and 5 women (age 22.81±3.48 years; body mass 65.82±8.45 kg; height 1.56±0.21 m; BMI 21.54± 1.35 kg/m2), they performed a maximal and incremental cardiorespiratory test (Course-Navette) and the WOD Pukie (150 burpees in the shortest possible time) on two days separated by 48 hours. Maximum heart rate, session heart rate, and recovery heart rate (1, 2, and 3 minutes) were recorded. The Shapiro-Wilk normality test and the Pearson correlation coefficient (95% confidence and a p-value of 0.05) were applied.Results: the maximum oxygen consumption was not significantly related in men (p>0.05), in the case of women it was positive with the recovery heart rate in all periods, but with significance in 1 minute (r = 0 .81; p<0.05) and 3 minutes (r = 0.93; p<0.01).Conclusions: maximal oxygen consumption was positively and significantly related to recovery heart rate in a functional fitness session in physically active women.
