TRICEPS DIPS EGZERSİZİ ÖNCESİ YAPILAN FARKLI ISINMA PROTOKOLLERİNİN ÇALIŞMA SIRASINDA ELDE EDİLEN KAS ELEKTRİKSEL AKTİVİTESİ ÜZERİNE ETKİLERİ

Öz

Çalışmanın amacı, kuvvet antrenmanından hemen önce yapılan bölgesel ısınma protokollerinin kasılma sırasında kas elektriksel aktivitelerine etkilerinin incelenmesidir. Bu amaçla çalışmaya aktif kırk dört sağlıklı gönüllü (22 kadın yaş: 19.9 yıl ±1.7, ağırlık: 54.1 kg ±8.2, uzunluk: 165.3 cm ±6.3; 22 erkek yaş: 20.7 yıl ±1.7, ağırlık: 68.4 kg ±10.1, uzunluk: 173.2 cm ±6.11) katılmıştır. Çalışmada kuvvet antrenman modeli olarak 3 set 10 tekrarlı triceps dips hareketi kullanılmıştır. Çalışma takvimi 5 gün olarak belirlenmiş ve ilk gün katılımcıların triceps dips hareketi sırasında maksimum izometrik istemli kasılma (MVIC) değerleri tespit edilmiştir. Bu değer diğer değişkenlerden elde edilecek olan değerlerin normalizasyonu için önemlidir. Diğer günlerde ise rasgele yöntemle pasif (ısınma yok) ve 5 dakikalık eliptik bisiklet, açma-germe ve masaj ısınma protokolleri antrenmanın hemen öncesinde uygulanmıştır. 3 set 10 tekrarlı triceps dips hareketi sırasında her set katılımcıların baskın kolunun tripecs kasından elektromyografi (EMG) kullanılarak kasın elektriksel aktiviteleri kayıt altına alınmıştır. İstatistiksel değerlendirme için elde edilen üç setlik değerlerin ortalamaları kullanılmıştır. İstatistiksel analiz için ANOVA testi ve bağımsız değişkenler t-testi uygulanmıştır. Çalışma sonucunda ısınma protokollerinin egzersiz anındaki kas elektriksel aktivasyonunda bir fark yaratmadığı bulunmuştur (p>0.05). Fakat ısınma protokollerinin cinsiyetler arası farklılıkları incelendiğinde ise pasif, açma-germe ve masaj ısınma protokollerinden sonra egzersiz anındaki kas elektriksel aktivasyonlarında kadın katılımcıların istatistiksel olarak daha fazla kas elektriksel aktivasyona sahip oldukları (p0.05). Çalışmanın sonunda karma egzersizlerin yada korfbol gibi karma spor branşları öncesinde daha yoğun ve aktif ısınma protokollerinin egzersiz anındaki kas elektriksel aktivasyonundaki cinsiyetler arası farkın ortadan kaldırılmasını desteklediği düşünülebilir.

THE EFFECTS OF DIFFERENT KINDS OF WARM-UP PROTOCOLS BEFORE TRICEPS DIPS EXERCISE ON MUSCLE ELECTRICAL ACTIVATION DURING THE TRAINING

Abstract

This study is to investigate the effects on regional warm-up protocols right before the strength workout on muscle electrical activities during the contraction. For this purpose, 44 healthy volunteers are included (22 female age: 19.9 yrs ±1.7, weight: 54.1 ±8.2, height: 165.3 ±6.3; 22 male age: 20.7 yrs ±1.7, weight: 68.4 ±10.1, height: 173.2 ±6.11). As strength workout method, 3 sets 10 repetitive triceps dips movement was used. Work schedule was decided to be 5 days, and on the first day, maximum isometric voluntary contraction (MIVC) of participants during triceps dips movement was determined. This value is important in normalizing the values obtained from other variables. On the other days, passive (no warm-up), 5 minutes of elliptical trainer, static stretching and massage warm-up protocols were randomly applied just before the training. During the 3 sets and 10 repetitive triceps dips movement, electoral activities of the muscle were recorded after every one of the sets by using electromyography (EMG) of triceps muscle of the participant’s dominant arm. For the statistical evaluation, average of the values from 3 sets was used. For statistical analyzes, ANOVA test and independent samples t-test were used. As a result, it was found that warm-up protocols make no difference in muscle electrical activation (p>0.05). But when it comes to the difference of warm-up protocols in genders, it has been found that female participants have more muscle electrical activation during the exercises after passive, stretching and massage warm-up protocols (p0.05). As a result of the study, it is thought that mixed exercises or more intensive and active warming protocols before the mixed sports like korfball support the wipeout the difference between genders in muscle electrical activation.
