Talent detection intends to support lifelong sports participation, reduce dropouts and stimulate sports at the elite level. For this purpose it is important to reveal the specific profile which directs children to the sports that connect to their strengths and preferences. This study evaluated a perceptuomotor skills assessment as part of talent detection for table tennis, a sport in which perceptuomotor skills are considered essential to cope with the difficult technical aspects. Primary school children (n = 121) and gifted young table tennis players (n = 146) were assessed using the Dutch perceptuomotor skills assessment measuring "ball control" and "gross motor function"...

In a recent paper entitled "A genetic-based algorithm for personalized resistance training", Jones et al. [1] presented an algorithm of 15 performance-associated gene polymorphisms that they propose can determine an athlete's training response by predicting power and endurance potential. However, from the design of their studies and the data provided, there is no evidence to support these authors' assertions. Progress towards such a significant development in the field of sport and exercise genomics will require a paradigm shift in line with recent recommendations for international collaborations such as the Athlome Project (see www...

The utility of hypoxia-inducible factor (HIF) prolyl hydroxylase inhibitors as therapeutic means for the treatment of patients suffering from anemia has been demonstrated for various different clinical settings. However, besides this intended use, HIF stabilizers can be the subject of misuse in amateur and elite sports due to their erythropoietic properties as recently proven by several cases of adverse analytical findings in doping control testing. Consequently, in order to allow for adequate and comprehensive test methods, knowledge about the drug candidates' metabolism and analytical options enabling appropriate detection windows in sports drug testing samples (i...

A significant proportion of patients undergoing hip arthroscopy for treatment of femoroacetabular impingement are athletes attempting to return to sport. Emerging data suggest hip arthroscopy has a high success rate in athletes returning to play at all competitive levels and ages. Although several factors are important in determining return to athletics, the results of hip arthroscopy appear promising in all athletes, from weekend warriors to elite professionals.

BACKGROUND: Individuals with an impairment make up over 15% of the world's population, many of whom can benefit greatly from participation in sport. The provision of medical services in disability sport is a challenging area with a lack of scientific evidence. Given the positive impact that sport can have on the people with an impairment, it is vital that measures are taken to better understand the medical issues posed by disability sport. It is well established that medications and supplements are over-used in sport, particularly within professional football, but there is no current evidence on medication or supplement use in elite disability football...

Introduction: During running and jumping activities, elastic energy is utilized to enhance muscle mechanical output and efficiency. However, training-induced variations in tendon spring-like properties remain under-investigated. The present work extends earlier findings on sport-specific profiles of tendon stiffness and cross-sectional area to examine whether years of distinct loading patterns are reflected by tendons' ability to store and return energy. Methods:Ultrasound scans were performed to examine the morphological features of knee extensor and plantar flexor muscle-tendon units in elite ski jumpers, distance runners, water polo players, and sedentary controls...

Metabolomics incorporates the study of metabolites that are produced and released through physiological processes at both the systemic and cellular levels. Biological compounds at the metabolite level are of paramount interest in the sport and exercise sciences, although research in this field has rarely been referred to with the global 'omics terminology. Commonly studied metabolites in exercise science are notably within cellular pathways for adenosine triphosphate production such as glycolysis (e.g., pyruvate and lactate), β-oxidation of free fatty acids (e...

CONTEXT: Anecdotal reports suggest elite sports clubs combine lower body positive pressure (LBPP) rehabilitation with a hypoxic stimulus in order to maintain or increase physiological and metabolic strain, which are reduced during LBPP. However the effects of hypoxia on cardiovascular and metabolic response during LBPP rehabilitation is unknown. OBJECTIVE: Evaluate the use of normobaric hypoxia as a means to increase physiological strain during body weight supported (BWS) running...

Two nuclear genes, ACTN3, encoding for the α-actinin skeletal muscle isoform 3, and ACE encoding the angiotensin-converting enzyme, have both been associated with quantitative physical performance traits in the general population. The purpose of our study was to assess the association between the two nuclear gene variants, R577X (rs1815739) in ACTN3 and I/D (rs4340) in ACE, with elite athletes’ performance and the effect of training on the mitochondrial DNA (mtDNA) content in peripheral blood. We evaluated the genotypes and frequencies of ACTN3 R577X and ACE I/D polymorphisms between soccer players (n = 43) and healthy non-athletic controls (n = 128)...
