Estimation of the energy cost in rhythmic gymnastics

Introduction The aim of the study was to measure the energy cost in rhythmic gymnastic. Methods Twelve elite rhythmic gymnasts belonging to the national French team participated in this study. Maximal oxygen uptake and lactate concentration were measured in laboratory following a maximal test, after the four implements (rope, clubs, hoop and ball) and after a training session. Results and discussion Maximal [image] values were ranged between 37.95 and 45.77 ml min super(-1) kg super(-1) and 25.12 ml min super(-1) kg super(-1) for training. The lactate concentrations were significantly higher (P < 0.05) for exercises including hoop, rope, clubs compared to those measured in laboratory P < 0.05). There was no correlation between oxygen uptake and blood lactate concentrations and the performance level of each gymnast. Rhythmic gymnastic was caracterised as an anaerobic sport.Original Abstract: Introduction Lobjectif de ce travail est de mesurer la depense energetique en gymnastique rythmique. Sujets et methodes Douze gymnastes rythmiques de lequipe de France ont participe a cette etude. la consommation doxygene et la lactatemie ont ete mesurees en laboratoire, apres les quatre exercices (corde, massues, cerceau et ballon) et au cours dun entrainement type. Resultats et discussion Les valeurs maximales de [image] sont comprises entre 37,95 et 45,77 ml min super(-1) kg super(-1) pour les quatre engins et de 25,12 ml min super(-1) kg super(-1) pour lentrainement. Les concentrations en acide lactique mesurees a lissue des exercices du cerceau, de la corde et des massues sont significativement superieures (p < 0,05) a celles mesurees en laboratoire a lissue de lepreuve maximale. Les valeurs de lexercice au ballon sont significativement inferieures (p < 0,05). Il ny a aucune correlation entre les valeurs de consommation doxygene et de concentrations dacide lactique de fin dexercice et le niveau de performances des gymnastes. la gymnastique rythmique se caracterise donc comme une activite de type anaerobie lactique.
