The Impact of 4-weeks Dominant Wrist-Forearm Strength Training Ipsilateral and Contralateral on the Strength

Abstract

The aim of this study; To investigate whether 4-week dominant wrist-forearm strength exercises have an effect on contralateral and ipsilateral strength. To work; 27 of them were exercise group (EG) (age: 19.70 ± 1.41 years, height: 176.73 ± 7.22 cm, body weight: 69.22 ± 9.51 kg) and 27 of them were the control group (KG) (age: 20.15 ± 1.66 years, height: 179.374 ± 5.49, body weight: 70.39 ± 7.43 kg) a total of 54 male volunteers participated. EG performed 4 sets of dominant (D) wrist flexion and extension exercises with dumbbells at 70% intensity for 4 weeks, 3 days a week. No study has been done on the non-dominant (ND) side. The repetitions in the sets were continued until the participant could not lift the weight with the appropriate technique (Fatigue). The data were collected by General Information Form, height meter, scale and digital hand dynamometer. Paired sample t-test was used to compare the before-after measurements of the groups. Two-way mixed ANOVA results were given in the examination of the change between the measurements obtained at the beginning of the study and at the end of the 4-week period in the study and control groups. As a result of the comparison of the pre and post tests’ means, statistically notional difference for the D clutch strength and ND clutch strength is respectively as (p<0.001). However, there is no notional difference in CG(p>0.05). A statistically significant time-dependent difference was found on D hand grip strength and ND hand grip strength measurement results (p<0.001). While TimeXGroup interaction was found to be statistically significant in the evaluation of D hand grip strength measurement results (p<0.001), TimeXGroup interaction was not statistically significant in the evaluation of ND hand grip strength measurement results (p>0.05). The main effect of the group variable (Regardless of the time variable) was not statistically significant in all data (p> 0.05). It can be said that this study has a positive impact on D hand clutch strength and ND hand clutch strength. Keywords: Cross transfer, strength, strength training.
