Title

The Effect of Endurance Training, Detraining and Shock Training on Lactate Transporters in the Gastrocnemius Muscle and Endurance Performance of Male Rats

Pages

Abstract

 Aerobic training can have an important role in delaying fatigue by increasing lactate transporters. However, changes in monocarboxylate transporters (MCTs) during detraining and the effect of, so-called, shock training on the maintenance of training adaptations during detraining have remained unknown. Therefore, the aim of this study was to investigate the effect of endurance training, detraining and shock training on the Endurance performance and protein levels of monocarboxylate transporters (MCT1 and MCT4) in gastrocnemius muscle of male rats. In this experimental study, 24 male rats (247. 05± 6. 75 g) were assigned to four groups: control, endurance training, endurance training + detraining and endurance training + shock training. The running program on a treadmill was performed for 12 weeks (5 sessions a week with the intensity of about 85% of VO2max in the last week). The detraining/shock training protocol (one session per week, for 40 minutes at a speed of 20-30 m/min) was applied from 10 th to 12 th week. Levels of MCT1 and MCT4 were measured by the ELISA method. Endurance performance was assessed using exhaustive test. The level of MCT1 of gastrocnemius muscle in the endurance training group was higher than the control group (P=0. 001). However, there were no differences in the level of MCT1 among detraining, endurance training (P=1. 000) and shock training (P=0. 998) groups. Endurance training, detraining and shock training did not significantly change MCT4 level of gastrocnemius muscle (P=0. 148). Detraining visibly decreased Endurance performance compared with the endurance training group (P=0. 001). Despite the significantly decreased performance of the shock training group compared with the endurance training group (P=0. 001), shock training prevented detraining induced performance loss (P=0. 006). Endurance training increases the MCT1 level of the gastrocnemius muscle. This increase is not influenced by detraining or shock training. However, it seems that shock training can ameliorate the loss of Endurance performance caused by detraining.
