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,
