Öğe The clinical effects of somatotype difference on isokinetic knee muscle strength and dynamic balance scores(Turkish Society of Physical Medicine and Rehabilitation, 2018) Şenol D.; Özbağ D.; Kafkas M.E.; Açak M.; Baysal Ö.; Kafkas A.Ş.; Taşkıran C.Objectives: The aim of this study was to present the somatotype features of young individuals without any symptoms and to identify whether isokinetic knee muscle strength and dynamic balance scores are affected by somatotype difference. Patients and methods: A total of 146 participants (88 males, 58 females; mean age 22.5±1.9 years; range 19 to 28 years) who had no symptoms were included in this study. Somatotypes of the participants were calculated using the Heath-Carter formula, and anthropometric measurements were taken from each participant. Knee flexion and extension muscle strengths at angular speeds of 90°/sec, 120°/sec and 150°/ sec were measured from the dominant and non-dominant limbs of the participants. Total balance, anterior/posterior balance, and medial/ lateral measurements were made to evaluate dynamic balance performances. Results: Six different somatotypes were found. Endomorphic mesomorph was the most common somatotype in 56 participants. There was no significant somatotype difference in men and women for dominant and non-dominant knee extension and flexion peak strength values at angular speeds of 90°/sec, 120°/sec and 150°/sec (p>0.05). No significant difference was found between the balance scores of men and women who had different somatotypes (p>0.05). Conclusion: Anatomic structure of the body, which is suitable for the sports branch, has an increasing effect on performance. © 2018 by Turkish Society of Physical Medicine and Rehabilitation.Öğe Effect of different resting intervals on serum creatine kinase and lactate dehydrogenase during isokinetic muscle strength(Edizioni Minerva Medica, 2014) Kafkas M.E.Aim. The aim of the study is that among exercise programs with different resting intervals, short resting intervals negatively affect LDH and CK enzyme activity.Methods. The study included 28 male volunteers (age 20.50+2.40 years, weight 72.80±5.75 kg, l74.65±l2.45 cm height) who did not regularly exercise. Study participants were randomly divided into two groups, with one group having 1 min resting interval (RIG-1) and the other group having 3 min resting interval (RIG-3), both working at 60°/sec speed isokinetic muscle strength. LDH and CK concentrations of both groups were measured in pre-test and post-test, 24 h (after 24 hours), 48 h (after 48 hours) and 72 h (after 72 hours).Results. Significant differences were found between the post-test and 24 h values of LDH concentrations of RIG-1 participants (p=0.023, p=0.012). In CK concentrations RIG-1 participants showed significantly different CK concentrations between 24 h and 48 h tests (p=0.021, p=0.018).Conclusion. Resistance exercises should be planned considering training days, and resting intervals and days. The findings of this study may help to optimize refreshment and resting intervals between training days for untrained individuals who have recently begun resistance exercises.Öğe Effects of a tennis toumament on players' band grip strength, pressure pain threshold and visual analogue scale(Edizioni Minerva Medica, 2014) Kafkas A.Š.; Kafkas M.E.; Durmuş B.; Açak M.Aim: Tennis is one of the most popular global sports. It is considerably important both as an international toumament and one of the Olympics games around world. The requirements of a tennis toumament are high, both mentally and physiologically. The aim of this study was to evaluate changes both of hand grip strength and pain pressure threshold values during toumament among amateur tennis players. Methods: The study involved two tennis groups. The first comprised 25 females (age 24.35±5.42 years, height 167.74±7.10 cm, weight 59.25±7.80 kg) and the second included 34 males (age 25.10±6.05 years, height 174.50±10.63 cm and weight 69.40±12.50 kg). Results: Pain pressure threshold and hand grip strength values were significantly different. Lateral epicondyle, deltoid and trapezius values were significantly lower after every match day compared with the first day of the toumament (P<0.05). Both female and male tennis groups' lateral epicondyle, trapezius, and deltoid values reduced significantly after the second, third, and forth day compared with the values of the first day of the toumament. Also, hand grip strength values significantly decreased after the second, third, and fourth day of female tennis group and decreased the third and fourth day of male tennis group (P<0.05). As a result, this research found a decreased sensitivity level of pain pressure threshold, hand grip strength and an increased level of visual analogue scale during consecutive toumament days. In terms of both pain pressure threshold and hand grip strength, values adversely affected from such toumament sports organizations. These tournaments have a busy schedule that may adversely affects the values of the upper extremity pain pressure threshold (lateral epicondyle, deltoid, supraspinatus, and trapezius). Therefore, especially during these tournaments tennis players should be careful.
