The main purpose of this research is to understand the strongest predictors of wearable adoption among athletes with an emphasis on the perceived ethics of biometric data. We performed a word co-occurrence study of biometrics research to determine the ethical constructs of biometric data. A questionnaire incorporating the Unified Theory of Acceptance and Use of Technology (UTAUT), Health Belief Model and Biometric Data Ethics was then designed to develop a neural network model to predict the adoption of wearable sensors among athletes. Our model shows that wearable adoption's strongest predictors are perceived ethics, perceived profit, and perceived threat; which can be categorized as professional stressors. The key theoretical contribution of this paper is to extend the literature on UTAUT by developing a predictive modeling of factors affecting acceptance of wearables by athletes, and highlighting the ethical implications of athlete's adoption of wearables.

BACKGROUND/OBJECTIVES: Mediterranean diet is an environmentally friendly and healthy diet model. The diet offers many vegetables, fruits, nuts, and olive oil to consumers. In addition, it provides moderate amounts of fish and chicken, smaller quantities of dairy products, red meat, and processed meat. The Mediterranean diet has a high anti-inflammatory and antioxidant content, and it causes many physiological changes that can provide a physical performance advantage. This study examined the effects of a 15-day menu, which was planned using foods with a low acid load within the Mediterranean diet rules, on the exercise performance, lactate elimination, anthropometric measurements, and body composition. SUBJECTS/METHODS: Fifteen professional male athletes between the ages of 13 and 18, who were engaged in ski running, were included in the experimental study. Dietary intervention was applied for 15 days. The athlete performances were evaluated by applying the vertical jump test, hand grip strength, 20 meters shuttle run test, and Borg fatigue scale. After the shuttle run test (every 3 min for 30 min), blood was drawn from the finger, and the lactate elimination time was calculated. Performance and lactate measurements, body analysis, and anthropometric measurements were taken before and after dietary intervention. RESULTS: The vertical jump height and hand grip strength increased after the intervention (P < 0.05). The test duration, total distance, the number of shuttles, and maximum oxygen consumption parameters of the shuttle run test increased (P < 0.05). After the intervention, the athletes' perceived fatigue scores decreased in several stages of the shuttle run test (P < 0.05). The lactate elimination time and athlete's body composition were similar in repeated measurements (P > 0.05). In the last measurements, the upper middle arm circumference decreased while the height of the athletes increased (P < 0.05). CONCLUSIONS: These results show that the Mediterranean diet is a safe and feasible dietary approach for aerobic performance and strength increase.

People have recently became interested in eco-friendly cycling that attracted further attention as a sport activity. The number of high school cyclists has increased due to the popularity of cycling; however, high school cyclists have trouble choosing cycling suits because there is no professional cycling suit for high school cyclists in Korea. Therefore, it is necessary to develop a professional cycling suit for high school cyclists because sportswear for athletes is an important means to improve performance. This study suggests a standard sizing system for high school student athletes' cycle tights. The subjects were 111 high school cyclists. The 3 clusters were categorized by cluster analysis, and the sizing system was classified according to three lower body types. The size intervals of waist girth, hip girth and height were 5cm, respectively. The most frequent sizes were 75-100-175 in figure type 1, 70-90-170 and 75-95-170 in figure type 2, 70-90-175 and 70-90-180 in figure type 3. The sizing system, which had frequencies more than 3.6%, was classified into 9 cases, 8 cases, and 5 cases, respectively by lower body types. The results will contribute to the development of athletic performance cycle wear for high school cyclists.

Materials produced with the help of new technology are used in the design of materials used in all science and engineering departments today. A sports engineering and sports equipment department is one of these departments. The use of nanotechnology in sports equipment is one of the most popular uses of this technology today. Nanomaterials have been used in sports equipment for many years, and reputable companies have benefited. Athletes' equipment allows them to display their skills to the fullest extent. It has always been a dream of professional athletes and their coaches to have unique equipment. As a result, engineers have spent all their time and effort solving this problem. Science and engineering can do various things to meet the needs of all sports levels, including specific and detailed designs, the use of appropriate materials, and standardization tests on equipment. However, these aspects must remain aligned with the latest technologies as they develop, just as with other sciences. These technologies, especially nanotechnology, are essential to sports equipment and devices developed today by sports engineers. This article examines the balls that use nanotechnology and can also improve the athlete's performance by using this technology in a specific structure. Using nanotechnology to make nanocomposite poly-hope balls, which makes them lighter and more acceptable, reduces the impact on the ball and increases its movement speed.

Purpose : The purpose of this study was to compare patients with anterior shoulder instability who were treated with an open Bankart procedure with those treated with an arthroscopic procedure, and to evaluate factors influencing the final outcomes and recurrence. Materials & Methods : One hundred seven shoulders underwent open Bankart repair, and fifty-one shoulders were treated arthroscopically. Average followup for open group was 34 months, and for arthroscopy group was 25 months. The Bankart Rating System by Rowe was used to evaluate the clinical outcome of the procedure. And, the patients were asked about any changes concerning their sports and professional activities. Results: According to Bankart Rating system by Rowe, open group had 97% fair to excellent results with 2 recurrent dislocation(1.8%) and 4 recurrent subluxation(3.6%), and arthroscopy group had 94% fair to excellent results with 3 recurrent dislocation(5.8%) and 4 recurrent subluxation(8%). In open group, 9 shoulders(8.4%) had the mild limitation of range of motion at the time of followup, and 2 shoulders(3.9%) in arthroscopy group. Age and gender do not seem to be a significant factor contributing to an increased re-recurrence rate. The incidence of re-recurrence seems to be affected by dominance, frequency, and patient's activity. The size of Bank art lesion might be also considered as a contributing factor. Conclusion: Either open or arthroscopic Bankart procedures are safe and effective methods with acceptable results if an adequate patient's selection, precise surgical technique and proper postoperative care are done. And arthroscopic surgery could be considered if the anterior instability is non-dominant, non-athlete, traumatic unidirectional and Bankart lesion has minimal erosion of the glenoid and it has thick and mobile labrum.
