PHYSIOLOGICAL DEMANDS OF YOUNG WOMEN’S COMPETITIVE GYMNASTIC ROUTINES
Journal Title: Biology of Sport - Year 2014, Vol 31, Issue 3
Abstract
The objective of this study was to investigate the physiological indices of competitive routines in women’s artistic gymnastics by characterizing post-exercise heart rate (HR), oxygen uptake (VO[sub]2[/sub]) and peak blood lactate concentration (L[sub]max[/sub]) in a group of eight young elite-oriented female gymnasts. HR was continuously monitored with Polar RS400 monitors during the test event simulating a competition environment. Within 5 s of the end of each routine, the breath-by-breath gas analyser mask was placed on the face to record VO[sub]2[/sub]. VO[sub]2[/sub]max was calculated by the backward extrapolation method of the VO[sub]2[/sub] recovery curve. Lmax was obtained during recovery (min 1, 3, 5, 7 and 10) subsequent to each event. One week later, HR, VO2 and L[sub]max [/sub]were measured during an incremental continuous treadmill test. The treadmill test was confirmed as the assessment with the highest physiological demand. The gymnasts reached their highest values of HR (183-199 beats · min[sup]-1[/sup]), VO2/Bm (33-44 ml · kg[sup]-1[/sup] · min[sup]-1[/sup]) and Lmax (7-9 mmol · l-[sup]1[/sup]) in the floor and uneven bars exercises. The vault was the event with the lowest HR (154-166 beats · min[sup]-1[/sup]) and Lmax (2.4-2.6 mmol · l[sup]-1[/sup]), and the balance beam had the lowest VO[sub]2[/sub] (27-35 ml · kg[sup]-1[/sup] · min[sup]-1[/sup]). The mean relative peak intensities attained in the different events, which ranged from 65 to 85% of the individual VO[sub]2[/sub]max and HRmax recorded in the laboratory, suggest that cardiorespiratory and metabolic demands are higher than previously indicated. The high percentage of VO[sub]2[/sub] measured, particularly after the floor event, suggests that aerobic power training should not be neglected in women’s artistic gymnastics.
