Öğe The effect of sports shoes on flat foot(Iermakov S S, 2020) Korkmaz, M. F.; Acak, M.; Duz, S.Purpose: This study was conducted to determine the effects of participation in sports on the structural deformities of the foot. Material: A total of 2013 athletes (1301 males, 712 females) who had regularly participated in sports for a minimum of three years were included in the study. Screening of the sole was performed using a podoscope as it is a reliable and practical device. The structure of the sole was evaluated with the highly valid Staheli index. Results: A significant relationship was detected between the ages of the athletes, years in sport, branch of sports variables and the prevalence of flat foot. However, no significant relationship was found between the athletes' gender and the prevalence of flat foot. Conclusions: It is thought that the training regimes, the floor on which the sports is performed and the shoes used in sports had effects on flat foot deformity. Based on our results, we assert that redesigning the competition shoes and using sports shoes with arch support during warm-ups, running and other sportive and educational drills outside the routine activities of the sports branch may be beneficial for foot health.Öğe Effects of a tennis tournament on players' hand grip strength, pressure pain threshold and visual analogue scale(Edizioni Minerva Medica, 2014) Kafkas, A. Sahin; Kafkas, M. Emin; Durmus, B.; Acak, M.Aim. Tennis is one of the most popular global sports. It is considerably important both as an international tournament and one of the Olympics games around world. The requirements of a tennis tournament 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 tournament 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 tournament (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 tournament. 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 tournament days. In terms of both pain pressure threshold and hand grip strength, values adversely affected from such tournament 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.Öğe Investigating the effects of wrestling gear in flatfoot deformity of wrestlers(Iermakov S S, 2020) Acak, M.; Korkmaz, M. F.; Taskiran, C.; Demirkan, E.Purpose: In this study, our aim was to determine the effects of wrestling shoes, wrestling mats and wrestling styles on postural deformation of the foot and to elaborate its possible causes. Material: Study group comprised of 158 athletes (109 males, 59 females) from 26 different countries who participated in the 12th World University Wrestling Championship. Of the athletes, 102 (59 females, 43 males) performed in freestyle and 56 performed in Greco-Roman style. The age range of the athletes was 19 to 31 years and they have done wrestling for 3 to 18 years. Were evaluated to determine the relationship between flatfoot deformity and gender, age, wrestling style and years in the sport. Footprint parameters were used to determine and evaluate the overall structure of the foot. The Staheli and the Chippaux-Smirak indexes were used in the study. Statistical analyses were performed using the SPSS v.21.0 software, with the significance level set at alpha=0.05. Results: No significant relationship was found either between the gender of the wrestlers or their age and their pes planus state. A significant relationship was detected between the wrestling style performed and the wrestlers' pes planus state, and between the years in the sport and their pes planus state. Conclusions: The fact that wrestlers wear the wrestling shoes for a long time can be a cause of pes planus. The center of mass of freestyle wrestlers shifts during continuous feet movement, and the surface of their soles extends the contact surface on the mat to maintain balance. This situation can also lead to a higher prevalence of pes planus in wrestlers. In addition, the wrestling shoes wrap around the Achilles tendon and thus the stretching of this tendon is restricted. Such restriction strengthens the opinion that freestyle wrestlers experience pes planus more.
