Support Vector Machine (SVM) has been shown to be an effective learning algorithm for classification and prediction. However, the application of SVM for prediction and classification in specific sport has rarely been used to quantify/discriminate low and high-performance athletes. The present study classified and predicted high and low-potential archers from a set of fitness and motor ability variables trained on different SVMs kernel algorithms. 50 youth archers with the mean age and standard deviation of 17...

Sports medical examinations of juvenile athletes provide an opportunity for preventive measures against sports-related diseases. Determining the leg axis deviation as a risk factor for future constraints may offer approaches for such measures. Data were obtained from 789 youth athletes: 166 with coronal plane knee misalignment and 623 without. After a seven-year period, 64 participants (m: 33, f: 31) from both groups were reassessed for the incidence of nonspecific chronic low back pain (CLBP). To distinguish participants with increased risk for CLBP, contingency tables for comparison of expected and joint frequency distribution testing and receivers operating characteristic (ROC) analyses for the weekly training time were conducted...

Ice hockey is a physiologically complex sport involving both the anaerobic and aerobic energy systems. The purpose of this study was to evaluate the anaerobic power output (PO) of top-level competitive youth hockey players. It was hypothesized that with each successive increase in age there would be an associated change in anaerobic PO. Two hundred and fifty-one male hockey players between the ages of 13-17 years of age participated in this study. All athletes completed a 30-second Wingate test as part of a pre-season physiological and fitness combine...

Although initially considered rare, anterior cruciate ligament (ACL) ruptures in pediatric patients recently have increased substantially as a result of greater awareness of the injury and increased participation in youth sports. Although pediatric patients with an ACL injury and a clinically stable joint may handle the injury well and return to sports activity without requiring surgical reconstruction, young, active patients with an ACL rupture and an unstable joint may be good candidates for ACL reconstruction to prevent ongoing instability and additional joint damage...

BACKGROUND: Lung cancer occupies the leading position of cancer incidence and mortality worldwide, including in the Czech Republic. Despite significant advances in systemic oncology treatments, lung cancer still has the worst prognosis, which is driving the need for innovative therapies and methods to treat this disease. Immunotherapy is a developing area of systemic oncology treatment, which has recently begun to be significantly applied to patients with lung carcinoma. The most useful type of immunotherapy currently employs checkpoint inhibitors, including CTLA-4 inhibitors (ipilimumab and tremelimumab) and PD-1/PD-L1 inhibitors (nivolumab, pembrolizumab, durvalumab, and avelumab)...

Targeting physical inactivity in children is pertinent to aiding in the decrease of childhood obesity rates. Only 33% of adolescents are obtaining the recommended goal of at least 60 min of physical activity per day. The objectives of this review are to summarize professional recommendations for physical activity and exercise in children and adolescents, and identify family-centred strategies that can be implemented by weight management clinicians. Clinically oriented recommendations and policy statements from professional organizations were identified through literature and internet searches, summarized using rubrics of aerobic, muscle strengthening and bone strengthening exercise, then examined for details on family-based focus, inclusion of child developmental stage and age, and application to the prevention and treatment of obesity...
