Development of tolerance to electrical muscle stimulations

Öz

Abstract

Electrical muscle stimulation (EMS) can be defined a non-conventional method as being applied electrical currents to the muscle tissues or motor points in order to performance improvement in sport. The effectiveness of EMS training method is related to the intensity of electrical currents applied during training sessions. The tolerance to electromyostimulation can be define as the ability to tolerate progressively increas­ing current intensity. Despite that very little information exists related to tolerance to electrical currents of muscle and nervous. In order to know, whether the human body develop tolerance to electrical currents or not, is important for the effective use of this method. The aim of this study is to examine that whether the tolerance against to max­imum comfortably tolerated electrical current intensity implemented during five weeks of isometric lower body electromyostimulation (LB-EMS) training program. Eighteen healthy students at sports sciences faculty between the ages of 18-27 implemented in a 5-week isometric LB-EMS training program. The results indicate that there is signifi­cant tolerance (p <0.05) were found against the electrical current. The rapid increase in tolerance at the initial phase of the 5-week EMS training has shown the tolerance against electrical current, an increase again afterwards followed by that phase, and that increase is observed a slight decrease in the last period of training followed.

Elektriksel Kas Uyarılarına Karşı Tolerans Gelişimi

Öz

 Özet

 Elektromyostimülasyon (EMS), deri üzerinden kas dokusu ya da motor noktalara uygulanan elektriksel akımlarla performans gelişimi elde etme amaçlı konvansiyonel olmayan bir antrenman yöntemidir. EMS antrenmanlarının etkinliği antrenmanlar sırasın­da uygulanan elektriksel akımların şiddetiyle ilgilidir. EMS’ye tolerans, giderek artan elektriksel akımlara dayanabilme yeteneği olarak tanımlanabilir. Buna rağmen kas ve sinirlerin elektriksel akımlara toleransı ile ilgili çok az bilgi bulunmaktadır. İnsan beden­inin elektriksel akımlara tolerans geliştirip geliştirmediğini bilmek bu metodun etkililiği için önem taşımaktadır. Buradan hareketle bu çalışmanın amacı, 18-27 yaş aralığındaki 18 sağlıklı spor bilimleri fakültesi öğrencisinin, 5 haftalık çok eklem içeren izometrik istemli kasılmalar üzerine uygulanan alt beden elektromyostimülasyon antrenmanları (AB-EMS) sırasında uygulanan maksimal tolere edilebilen akım şiddetine karşı toler­ans gelişimi gösterip göstermediklerini araştırmaktır. Sonuçlara göre EMS’ye anlamlı düzeyde (p<0.05) tolerans gelişiminin olduğu görülmüştür. Elektriksel akımlarına toleransın 5 haftalık EMS antrenmanının başlangıç aşamasında hızlı bir artış gösterdiği bu hızlı artışı kısa bir duraklamanın izlediği daha sonrasında yine bir artışın olduğu ve bu artışı takiben antrenmanın son dönemlerinde küçük bir düşüş gözlemlenmiş olduğu görülmektedir.
