Objective: The purpose of this study is to determine the relationship between strength, flexibility, and field tests of upper extremity in healthy individuals. Materials and Methods: Fifty healthy individuals (25 women, 25 men) volunteered in the study. The physical and clinical characteristics of the participants were questioned using an evaluation form. Muscle strength was measured using a hand dynamometer. Flexibility was measured with a tape. The Y balance test (YBT) and medicine ball throwing were used as upper extremity field tests. Pearson and Spearman correlation analyzes were used to determine the relationship between the parameters. Results: There was a moderate correlation between medicine ball throwing and YBT total scores (r=0.507, p<0.01). It was revealed that strength and flexibility of the upper extremity were related to YBT scores (p<0.01 and p<0.05, respectively). Conclusions: For healthy individuals, there are relations between strength, flexibility and field tests. Increased strength and reduced flexibility for the upper extremity increases physical performance and balance.
This study was planned to compare the effectiveness of high voltage pulsed galvanic (HVPG) stimulation, Russian current and isometric exercise on quadriceps femoris (QF) isometric muscle strength in healthy young women. Methods: Forty-six healthy young women were included in the study. Before and after the training, the dominant side QF isometric muscle strength of participants was assessed with the isokinetic dynamometer. The peak torque and average torques of the participants were recorded after the test. The training was planned as HVPG current group (n=16), Russian current group (n=15) and isometric strengthening group (n=15). All treatments were performed under physiotherapist supervision for a total of 15 sessions for three days a week for five weeks. Results: The quadriceps isometric muscle strength was significantly increased in all groups in terms of peak torque and average torque values after training compared to pre-training values (p<0.05). No statistical difference was found between the groups when the peak torque and average torque delta values were compared (p>0.05). Conclusion: The highest rate of change belongs to the HVPG group in terms of increasing the QF isometric muscle strength. Therefore, we recommend using it in clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
