Comparison of Motorcyclists' Hand Grip Strength and Reaction Time
(Asoc Didactica Andalucia, 2022) Tekin, D.; Tekin, Demet; Agopyan, A.; Terapi ve Rehabilitasyon Bölümü
The purpose of this study was to compare hand grip strength and reaction times in male motorcycle racers grouped according to different ages and the classes of motorcycle used and determine the relation between these characteristics. Sixty-five healthy male motorcycle racers were divided into four groups according to their age and the power of the motorcycles' engine: (Group-1 [G1] = 600CC/23-34 years; Group-2 [G2] = 600-CC/35-48 years; Group-3 [G3] = 1000-CC/23-34 years; Group-4 [G4] = 1000-CC/35-48 years). Then, Nelson's reaction time and maximal hand grip strength were measured for both hands. There were no significant differences between the groups' grip strength (p>0.05). It was found that G1's right-and left-hand reaction time was faster than that of G2, and G1's left-hand reaction time was faster than that of G3 (p<0.05). The right-hand visual reaction time was found to have a negative weak correlation with the left-hand absolute grip strength (r=-0.247, p=0.047), and there was a weak positive correlation between the left-hand visual reaction time and height (r=0.315, p=0.011). G1's right-hand visual reaction time was better than that of G2 (p < 0.001), and G1's visual left-hand reaction time was better than those of G2 (p < 0.034) and G3 (p < 0.011). Although the absolute and relative hand grip strength values did not differ according to the ages and the engine power of the motorcycle used, it was found that the simple reaction time increased with increasing age.

Effect of Body Size on Pulmonary Function in Male and Female Dancers
(Editura Universitatii din Pitesti, 2020) Tekin, Demet; Terapi ve Rehabilitasyon Bölümü
Introduction: Pulmonary function influence the performance of dancers during their trainings and also their performance stage. Therefore, it is important to investigate the factors that effects the pulmonary function. The effect of body size on resting pulmonary function in modern dancers is unknown but may be related to sex differences. Accordingly, the purpose of this study was to determine the effect of body size on resting pulmonary function in male and female modern dancers with the same training levels. Materials and Methods: Thirtyeight (n=18 male; n=20 female) undergraduate modern dancers participated voluntarily and their exercise levels (minimum of 5 days/week, 3 hours/day) and training histories (at least 4 years) were similar. All dancers completed pulmonary function test with a computerized spirometer (MIR, Spirobank, Rome, Italy) according to the American Thoracic Society (ATS) guidelines. Results: There was a significant difference (p < 0.05) between the genders in terms of vital capacity-best (VC-best) and maximum voluntary ventilation-best (MVV-best). The values were significantly higher in the male than in female dancers, and body size had a significant effect, with a small effect size (< 0.2) on the VC-best (F(1,25)= 4.902, p = 0.036) and MVV-best (F(1,25) = 7.864, p = 0.010) values. Conclusion: Although the effect size was small, the effects of body weight, height, and body mass index on the VC-best and MVV-best values were influenced by the fact that male dancers have higher resting respiratory function performance. In a practical contribution, the current results suggest that it is necessary to consider the gender factors when planning and organizing dance training with different models. © JPES.
