Comparaison de la dépense énergétique lors d’un entraînement dynamique avec ou sans vibration corps entier chez des femmes régulièrement entraînées

Summary: Aim: Values of energy expenditure during a circuit training realized with or without whole-body vibration (WBV) have been compared in women regularly trained with WBV. Methods: Ten women performed firstly, a test of maximal oxygen consumption and first ventilator threshold determination. Then, during two other sessions, they realized in a random order two training programs with or without WBV, composed by sequences of dynamic exercises during a 30-minute period. Energy expenditure was calculated from oxygen consumption values during the whole test. Results and discussion: A significant effect of vibration was observed on energy expenditure values during the training program. Adding vibration leads to an increase in energy expenditure by 15.48% when compared with the same program without vibration. Exercise intensity during the 30-minute exercise was respectively 52.7±3.1% VO2max with vibration vs 43.7±3.3% VO2max without vibration. Conclusion: These results indicate that during a training program composed by sequences of dynamic exercises, vibration leads to a significant increase in energy expenditure. Thus, it suggests that vibration could be considered as an alternative method to elicit a cardiovascular solicitation especially in population not motivated to practice classical locomotion exercises, classically used to maintain aerobic fitness.
