The foot absorbs shocks with its arches, muscles, ligaments and joints, and bodyweight transmission and it pushes the body forward during all movement patterns. Pes planus is more important in sports activities that include balance and sports performance, such as walking, running, jumping, or transferring weight to a single lower limb. This study, conducted with this information in mind, aims to examine the effects of pes planus deformity on balance and vertical jump performance. Fifty athletes were included in the study. The presence of pes planus was evaluated according to the Feiss line. Balance measurements were performed with a Balance System SD Biodex. Vertical jump performance was recorded using an Omegawave jumping mat. The relationship between the pes planus grades of the participants and their balance and jump performances was analyzed using the Spearman correlation method. Vertical jump and Limit of stability (LOS) was significantly correlated with pes planus.

Aim: The aim of this study was to examine the effects of 8-week core strength training on the repetitive sprinting ability, anaerobic power, body mass and fatigue indexes of football players. Methods: 15 male football players who play football regularly participated in the study. A core strength training program was applied to the research group using BOSU (Theraband, USA) elastic band (Theraband, USA). Before and after the study, the participants were analyzed with Tanita BC418 and their Body Mass Indexes (BMI) were taken. The height of the participants was measured with a stadiometer with a sensitivity of 0.01 cm. The data were analyzed using the SPSS 22 package program. Paired T Test was used for pre-test and post-test comparison between the two groups as the data showed normal distribution. Results: A high level of significant difference was found in the RAST and BMI values of the participants before and after the training when the averages were compared (p<0.05). A high level of significant difference was found in the Maximal Power and Fatigue Index values of the study participants when the pre- and post-training averages were compared (p<0.05). Conclusion: As a result, 8-week core exercises with Bosu and Tera tape improved the ability of repetitive sprinting, which is one of the important features of football players. As a result of the study, it can be said that the BMI level of the football players increases with the muscle mass developed as a result of core training.

Background: Previous research has reported a strong relationship between vertical jumping, sprinting, and agility, as a reflection of lower-limb power. Unilateral analysis of this relationship has not yet been explored. This study primarily investigated the associations between single-leg countermovement jump (CMJ), sprint, and agility performances in youth basketball players. Methods: Thirty-five male basketball players from the youth category (age 15.06 ± 2.62 years, n = 32 right-limb dominant; n = 3 left-limb dominant) performed single-leg CMJ, 20 m sprint, and T-drill agility tests over two sessions. Force–time-related performance variables were measured using a single-leg CMJ test on a Kistler force plate. Results: Significant moderate to large negative correlations were observed between single-leg CMJ variables, 20 m sprint, and T-drill agility, except for mean force for both dominant and non-dominant leg measures (r = −0.384 to −0.705). Mean power and mean force were correlated with the physical characteristics of the athletes for both legs (r = −0.389 to −0.843). Flight time and jump height were identified as the best predictor variables for both sprint and agility time in the stepwise model (R2 = 0.608 to 0.660). No statistical inter-limb differences were found during the single-leg CMJ test (p > 0.05). Conclusions: The study findings suggest that youth basketball players with greater single-leg jump output most likely have better sprint and agility performances. Thus, trainers and athletic performance coaches may include unilateral limb exercises in their training programs to enhance lower-limb explosive performance and reduce limb asymmetries.

Purpose: The fact that the sports branch that the athletes are interested in is included in the group of indoor and outdoor sports or team and individual sports can create differences in the motivation levels of the athletes. In this study, it was aimed to compare the motivation levels of team and individual athletes who do sports in Indoor and Outdoor.Method: The Sports-Specific Achievement Motivation Scale (SSAMS) developed by Willis (1982) was used to determine the motivation levels of the athletes in the study. The study consists of athletes who take part in Archery, Athletics, Judo, Tennis, Muaythai, Shooting (Weapon), Volleyball, Football, Basketball, Handball and Field hockey teams in Turkey. A total of 259 athletes, 170 men and 89 women, in these teams were included in the study.Findings: When we compared the motivation levels of individual and team athletes, a significant difference was found in the sub-dimensions of “motivation to show strength”, “motivation to approach success” and “avoiding failure” (p < 0.05). While a significant difference in the sub-dimensions of “motivation to show strength” and “motivation to approach success” was in favor of team athletes, “motivation to avoid failure” was found in favor of individual athletes (p < 0.05). Motivation levels of indoor and outdoor athletes. A significant difference was found in the motivation sub-dimensions of “motivation of strength” and “motivation of avoiding failure” of indoor and outdoor athletes (p < 0.05). It is seen that the significant difference is in favor of indoor athletes.Result: As a result; It has been determined that the sports branch differences that the athletes are interested in, the aims of their orientation to sports, the level of communication between the athletes studying physical education and sports training and the people who are in direct and constant communication, and the spatial differences in which the interested sports branch is performed can play an active role in the motivation levels of the athletes. The scarcity of studies on athletes in different branches doing sports in indoor and outdoor areas in the literature has shown that more studies are needed in this area.
