Behavior of heart frequency and perception of effort in different jump session methodologies

Abstract

Objective: The aim of this study was to verify if different strategies in changes intensity of Jump workout are effective to promote changes in heart rate (HR) and perceived exertion (PE) of women Jump practitioners. Materials and Methods: The sample was composed of nine women Jump practitioners (25.44 ± 3.81 years), which participated in the following protocols: anthropometric, familiarization, standard jump session and meeting with different strategy. Each strategy had a duration of six minutes with specific movements on the mini trampoline, being evaluated HR (heart rate monitors) and PE (Scale Borg RPE). Different strategy constituted in increasing of implementation pace, increased the foot force application on the mini trampoline and increasing the movements amplitude. For data analysis was used descriptive statistics with mean and standard deviation, and the variables were compared by repeated measures ANOVA (α = 5%). Results: The results showed significantly higher values of FC rate strategy (155 ± 11 bpm; p=0.013), strength (153 ± 10 bpm; p=0,011) and amplitude (160 ± 9 bpm; p=0,001) when compared to default session (135 ± 13 bpm). The FC was greater in amplitude strategy than strength strategy (p <0.05). The PE values ranged between 13 and 16, and all of the different strategies were higher than the default session (p <0.05). Conclusion: We conclude that the strategies used are effective for the change in intensity in the Jump workout.
