Background and Study Aim: Electromyostimulaiton (EMS) has been used for both physical therapy and strength improvements for a few decades. This study aimed to investigate the effects of a four-week local-EMS training performed on a fingerboard (FT) in wrist strength and endurance. Material and Methods: Sixteen physically active, non-climber students were divided into EMS+FT and FT groups. Each group performed the same training program about 25 min a day, 3 days a week for four weeks. The EMS+FT implementation was performed with a signal width of 260 ms and a frequency of 60 Hz. Before and after training, isokinetic measurements were collected. The parameters used in the research during flexion and extension at 60 and 180°/sec were; Peak Torque (PT), Peak Torque/Body Weight (PT/BW), and Average Power (AP). Results: The EMS+FT group showed statistically significant alterations in all of the parameters (p<0.01 and p<0.05) except in the left wrist AP during flexion and extension at 180°/sec. However, the FT group showed significant changes in only wright wrist AP during extension at 60°/sec, and wright and left wrist AP during flexion at 180°/sec, and left wrist PT during extension at 180°/sec. Conclusions: Accordingly, it could be inferred that FT done by using EMS for four weeks improve the isokinetic wrist strength and endurance significantly. Muscular fitness has an essential role in climbing performance, and this study points that EMS trainings on fingerboard could be used to enhance the climbing performance.
Object ve: Although the COVID-19 outbreak affected almost all the people globally, the number of studies investigating the effects on professional athletes are very low. Therefore, we aimed to examine anxiety levels, mental toughness and daily habits of professional and recreational athletes during the early phase of the pandemic and compare these with sedentary control objects.Mater als and Methods: 634 participants were evaluated in April 2020 with an online survey consisted of sociodemographic data, exercise habits and outbreak-related questions, along with Turkish versions of Sports Mental Toughness Questionnaire (SMTQ) and State-Trait Anxiety Inventory (STAI). 329 of the participants were professional athletes, 135 were recreational athletes and 170 were sedentary people.Results: Professional athletes (PROs) scored significantly higher (p<0.017) than recreatio-nal athletes (RECRs) and sedentary people (SEDs) on SMTQ and State-Anxiety Scores, but not on Trait-Anxiety Score (p˃0.05). Besides, there were no significant differences between RECRs and SEDs on any of the scores (p˃0.05). For SMTQ scores; activity level, gender and age are found to be significantly predictive. State-Anxiety scores were only significantly correlated with activity levels, whereas, gender and age were significantly correlated with the Trait-Anxiety scores (p<0.05). Conclus on:Being a high-level professional athlete is related to higher state anxiety levels during the COVID-19 outbreak. Even though professional athletes are mentally tougher, which will help them cope with high anxiety levels, they may need extra psychologic support as long as the pandemic and restrictions continue.
Background. Tissue stiffness measurement by ultrasound elastography is commonly used for internal organs and tendons. In this study, rectus femoris, vastus medialis, vastus lateralis, biceps femoris, and semitendinosus muscles' stiffness of patients who underwent anterior cruciate ligament reconstruction surgery was followed up by ultrasound elastography. Methods. 19 male recreational athletes aged between 18-40 years who had undergone anterior cruciate ligament reconstruction surgery with semitendinosus grafting method were included in the study. All patients received a standardized home exercise program and a standardized supervised rehabilitation program. Thigh muscle stiffness measurements were performed at post-operative first-week, first-month, secondmonth, and third-month. Results. There was a significant difference between non-operated and operated knees at first measurement (p < 0.05). The second measurement was higher than the first, and the third measurement was higher than the second for both legs (p < 0.05). Rehabilitation process has increased muscle stiffness of both legs, and there was still a significant difference between non-operated and operated knees at third month (p < 0.05). Conclusions. Post-operatively decreased thigh muscle stiffness increases with physical rehabilitation. Therefore, ultrasound elastography can be used as an additional follow-up tool. Moreover, theoretically it might be a return to sports criteria if baseline values are available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
