[The influence of vibration training in combination with general magnetotherapy on dynamics of performance efficiency in athletes].
Abstract

The objective of this study was to evaluate effects of a combined treatment including vibrostimulation and magnetotherapy on the working capacity of athletes. Participants of the study were 8 male judo wrestlers. It was shown that implementation of a specialized training program comprising seances of vibration loading and general magnetotherapy 40 and 60 min in duration respectively during 3 consecutive days produced marked beneficial effect on the hormonal status of the athletes. Specifically, the three-day long treatment resulted in a significant increase of blood cortisol and testosterone levels considered to be an objective sign of improved performance parameters in athletes engaged in strength and speed sports. The optimal length of vibration training during 3 days of specialized training is estimated at 20 to 40 minutes supplemented by general magnetotherapy for 60 minutes.

Abstract
Peroxisome proliferator activated receptor (PPAR) is a main regulator of energy metabolism, as it regulates the expression of genes encoding several key muscle enzymes involved in fatty acid oxidation. Importantly for power sports, it may affect pathways of glucose metabolism, which can be critical in power-based sports. The aim of this study was to analyse the distribution of the PPAR gene polymorphisms in mixed power/endurance athletes. The study was carried out on elite combat athletes and sedentary individuals, in an attempt to determine possible relationships between genotype and physical performance. We tested 60 male elite Polish combat athletes. Control samples came from 181 unrelated sedentary volunteers. The G/C polymorphic site in PPAR intron 7 was scanned using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) protocol with TaqI enzyme. Differences in the distribution frequency of this polymorphism were assessed by chi-square analysis. The results revealed that frequencies of the PPAR GG genotype (73.33% vs. 54.70%; P=0.04) and G allele (82.50% vs. 70.17%; P=0.01) were significantly higher in the elite combat athletes compared with sedentary controls. The results confirm the significance of the PPAR gene as a useful genetic marker in combat athletes. However, these results should be supported with more experimental data on PPAR polymorphisms with larger groups of elite athletes.
