Fatigue level through objective and subjective markers in Bodycombat sessions.

Abstract

Introduction: The relationship between cardiorespiratory exercise and health is widely accepted. There are only few studies that clarify the physiological responses in fitness classes, such as Bodycombat.
Objective: Assess fatigue level of a Bodycombat session alternating the intake of a high-carbohydrates and a high-fat breakfast, measuring heart rate, blood lactate and the perceived exertion by Borg scale and speech test.
Methods: A cross-sectional observational quantitative study was conducted in women who regulary practice Bodycombat sessions. Two types of diet were available with 70% fat or carbohydrate derived calories. The heart rate, lactate, Borg scale and Speech test (10 points) were taken through the sessions. Descriptive evaluation was made with mean comparison, standard deviation, and variable correlation with T-test.
Results and discussion: The average heart rate value in pre and post-session, lactate and Borg scale indicate an aerobic predominance activity. In addition, these markers were lower when performing a high pre-activity HCO intake; however, no significant differences were shown between intakes.
Conclusion: Bodycombat can be considered an aerobic predominance activity however, the large difference between the individual data does not clearly indicate the energy metabolism used so it is considered important to conduct studies relating diet and fatigue markers.
