Effect of Two Tapering Methods on Interleukin-6, Cortisol and Performance in Elite Male Wrestler

Abstract

Abstract.Purpose: This study examined that effect of two types of tapering on interleukin-6(IL-6), cortisol and performance in elite male wrestler. Material: After 4 weeks of progressive training, wrestlers were randomly divided into three equal groups, 1-control group (N=10) continued performing progressive training for one week, 2-taper group 1 (N=10) continued with a 50% reduction in training volume for one week, 3-taper group 2 (N=10) continued with a 75% reduction in volume of training for one week .plasma blood IL-6 and cortisol levels were assayed from analysis obtained via standard ELISA. Also general strength of muscles was recorded as a performance test. All data were collected before and after progressive training and also after one week of tapering period. Results: There were significant reduction of IL-6 and cortisol levels in both tapering group comparing with control group (P≤0.05).There was significant reduction of IL-6 and cortisol levels among tapering 50% and tapering 75% after tapering period (P≤0.05). Also there was significant increase of general strength of muscles between tapering 75% and control group (P≤0.05). Conclusion: hence, one week tapering with 75% reduction in training volume after progressive training while the intensity kept high is effective strategy for reduction of IL-6, and cortisol levels and also increase performance. It seems that higher reduction of training volume when the intensity kept high is a good strategy for wrestler before main competition.

“…From positions of pre-nosological diagnostic it can be interpreted as result of loads' feasibility, for overcoming of which organism needs only its own adaptation reserves. Table 2 data reflect stability of adaptation processes of elite sportsmen as well as formation of adaptation trace, which is analogous to the described in work by Meerson and Pshennikova (1988). Changes in less experienced sportsmen shall be understood as tension of LP-AOS system and its passing to new level of functioning.…”

Step vs. Two-Phase Gradual Volume Reduction Tapering Protocols in Strength Training: Effects on Neuromuscular Performance and Serum Hormone Concentrations

“…However, a higher reduction in the training volume, longer duration of the taper or both may be required to allow the fatigue to dissipate after an overload period (22,24). Mehranpour et al (16) demonstrated that a 75% reduction in the training load resulted in more favorable changes in the neuromuscular performance and serum hormone concentrations than a 50% reduction in male wrestlers over a 1-week tapering period. Taking together, these results suggest that a higher volume reduction rate at the beginning of the taper may be more beneficial if the preceding training period has been designed to induce some overreaching.…”
