The purpose of this study was to assess the effects of recovery duration on maximal inspiratory pressure and heart rate (HR) responses during Thai boxing exercise in obese female subjects.
Methods: Ten obese (Class I) female subjects (aged 21.5 ± 0.5 years) participated in this study. A Thai boxing exercise protocol was completed on three separate occasions, comprising 5 3-minutes rounds, with either 2 (3:2), 4 (3:4) or 6 (3:6) min recovery. Maximum inspiratory pressure (MIP) was assessed using a hand-held mouth pressure meter before (Pre) and after (Post) the Thai boxing exercise. HR was assessed throughout exercise and during the intermittent recovery periods. Data were analyzed using ANOVA with Bonferroni post hoc analysis. A statistical significance was accepted at p < 0.05.
While HR increased (p < 0.05) during exercise in all three exercise protocols, HR was higher (p < 0.05) during recovery in the 3:2 condition compared with the 3:4 and 3:6 conditions, respectively. Moreover, MIP was lower post-exercise compared to pre-exercise in all three exercise protocols (p < 0.05), however no between-condition differences were observed (p > 0.05).
This study indicated that recovery duration between rounds during Thai boxing exercise influences the recovery of HR, but not MIP, in obese class I women.
