Lactic acid and other associated components of anaerobic glycolysis have an inhibiting effect on performance through various processes. It has been identified that the level of performance from elite gymnasts positively correlates with decreases in blood lactate concentrations (Jemni et al, 2003). The purpose of this study was to analyse the blood lactate concentrations found in male gymnasts who perform at a lower competitive level. Pre-determined modifred NDP (National Development Programme) routines were completed on six pieces of apparatus, each set out in Olympic order. Gymnast's heart rate was monitored and a period of standardised active recovery employed before rotation onto a new piece of apparatus. It was supposed that the active recovery period would facilitate a consistent reduction in blood lactate concentrations between routines. Active recovery involved five minutes of cycling at sixty rpm (revolutions per minute) on a standard cycle ergometer. Six male gymnasts (20.6 f 1.75 years) participated in the study. Gyrnnasts displayed higher concentrations of lactate on the floor discipline (3.0 t I.23), however no significant differences (p<0.05) were established between any of the apparatus. Heart rate analysis revealed that rings induced the highest mean heart rate (140.4 ! 20.78 beats per minute); yet the post-routine value for floor (161.0 I 14.5 beats per minute) produced the highest heart rate. It was concluded that the displayed blood lactate concentrations reflect the individual apparatus involved and not the standard of the participating gymnast. Standardised active recovery proved beneficial in reclucing blood Iactate concentrations yet it is supposed that the combination of low-intensity modified NDP routines and such means of active recovery accounted for the lack of extreme values for blood lactate, which consequently led to no significance being established.
