Our study in the Journal of Sports Sciences was originally designed to test whether the bar-velocity is a precise indicator of the power training intensity (i.e., optimum loads) in different exercises commonly included in athletes' training programs. Furthermore, we presented secondary findings, related to the actual results obtained in our assessments. As a cross-sectional study with clear objectives, we focused on discussing issues and applications pertaining to neuromuscular training interventions, such as: (1) describing the advantages of using bar-velocities to control the power training intensity, (2) defining a range of loads capable of maximizing the power production in certain ballistic and traditional exercises, and (3) revealing the differences between these exercises and the respective implications for training...

E Ortega, C J K Wang
Heart rate variability (HRV) is commonly used in sport science for monitoring the physiology of athletes but not as an indicator of physiological state from a psychological perspective. Since HRV is established to be an indicator of emotional responding, it could be an objective means of quantifying an athlete's subjective physiological state before competition. A total of 61 sport shooters participated in this study, of which 21 were novice shooters, 19 were intermediate shooters, and 21 were advanced level shooters...

Complex systems applications in human movement sciences have increased our understanding of emergent coordination patterns between athletes. In the current study, we take a novel step and propose that movement coordination between athletes is a multiscale phenomenon. Specifically, we investigated so-called "complexity matching" of performance measured in the context of rowing. Sixteen rowers participated in two sessions on rowing ergometers: One individual session of 550 strokes and one dyadic session of 550 strokes side-by-side with a team member...

Although sport participation is encouraged throughout the lifespan, little research has been conducted on the role of sport in development later in life. This qualitative study explored adults' experiences of development within the context of Masters sport. We interviewed 14 adults (nine men and five women) aged 46-61 years involved in Masters sport. Data was interpreted drawing upon frameworks from youth sport (i.e., Personal Assets Framework for Sport; Côté, J., Bruner, M., Strachan, L., Erickson, K., & Fraser-Thomas, J...

Background: The purpose of this paper was to report normative data on regional sweat sweat-sodium concentrations of various professional male team-sport athletes, and to compare sweat-sodium concentrations among sports. Data to this effect would inform our understanding of athlete sodium requirements, thus allowing for the individualisation of sodium replacement strategies. Accordingly, data from 696 athletes (Soccer, n = 270; Rugby, n = 181; Baseball, n = 133; American Football, n = 60; Basketball, n = 52) were compiled for a retrospective analysis...

PURPOSE: Classification is a defining factor for competition in wheelchair sports, but it is a delicate and time-consuming process with often questionable validity.(1) New inertial sensor based measurement methods applied in match play and field tests, allow for more precise and objective estimates of the impairment effect on wheelchair mobility performance. It was evaluated if these measures could offer an alternative point of view for classification. METHODS: Six standard wheelchair mobility performance outcomes of different classification groups were measured in match play (n=29), as well as best possible performance in a field test (n=47)...

Importance: Scientific and lay interest in negative outcomes associated with exposure to repetitive brain trauma (RBT) continues to strengthen. Concerns about the association between RBT and dementia began more than a century ago, but have resurfaced in the last decade with the more recently described chronic traumatic encephalopathy (CTE). Chronic traumatic encephalopathy is a tauopathy associated with RBT that has become inextricably linked to conversations about sport-related concussion and mild traumatic brain injury...

Wearable sensors allow continuous monitoring of metabolites for diabetes, sports medicine, exercise science, and physiology research. These sensors can continuously detect target analytes in skin interstitial fluid (ISF), tears, saliva, and sweat. In this review, we will summarize developments on wearable devices and their potential applications in research, clinical practice, and recreational and sporting activities. Sampling skin ISF can require insertion of a needle into the skin, whereas sweat, tears, and saliva can be sampled by devices worn outside the body...

BACKGROUND: In 2013, the National Academy of Sciences emphasized the need to develop, implement, and evaluate effective large-scale educational strategies to improve the culture of concussion in youth and high school sports. In support of this recommendation, in this article we summarize research on factors that contribute to the culture of concussion. METHODS: We conducted the literature search using 7 electronic databases. We used a scoping review method to identify studies that addressed knowledge, attitudes, behaviors, use of educational resources, and interventions related to concussion among young athletes, coaches, and parents...

BACKGROUND: Learning transfer is defined as an individual's capability to apply prior learnt perceptual, motor, or conceptual skills to a novel task or performance environment. In the sport sciences, learning transfers have been investigated from an athlete-specific perspective. However, sport scientists should also consider the benefits of cross-disciplinary learning to aid critical thinking and metacognitive skill gained through the interaction with similar quantitative scientific disciplines...

Pain is a common problem among elite athletes and is frequently associated with sport injury. Both pain and injury interfere with the performance of elite athletes. There are currently no evidence-based or consensus-based guidelines for the management of pain in elite athletes. Typically, pain management consists of the provision of analgesics, rest and physical therapy. More appropriately, a treatment strategy should address all contributors to pain including underlying pathophysiology, biomechanical abnormalities and psychosocial issues, and should employ therapies providing optimal benefit and minimal harm...

Zella E Moore, Kehana Bonagura
Clinical sport psychology (CSP) is a contemporary, empirically informed model that employs a scope, style, and mode of practice built upon cutting-edge findings from both clinical and sport sciences, and that follows the sound methodological traditions of clinical psychology [1(••)]. Conceptualizing athletic performance and well-being through the context of empirical research in both athletic and nonathletic domains of functioning, CSP practice can involve the enhancement of athletic performance, and also the personal development and psychological well-being of performers...

Despite a long standing assertion that sociocultural domain is one of the factors constituting human psychological phenomena, sport psychological science has only recently begun to examine culture as the principal basis of physical activity and sport participants' behaviour, wellbeing, engagement, and performance outcomes. Emphasizing the centrality of culture in bringing meaning to athlete careers and life projects, I summarise empirical literature explicitly positioned within cultural sport psychology (CSP)...

Apollo 13 was initially looking like it would be the smoothest flight ever. After the explosion of an oxygen tank, however, the astronauts were close to spending the rest of their lives in rotation around the planet. This well-known incident is used to further discuss the link, or lack thereof, between sport-science research and current field practices. There is a feeling that the academic culture and its publishing requirements have created a bit of an Apollo 13-like orbiting world (eg, journals and conferences) that is mostly disconnected from the reality of elite performance...

Recent work has espoused the idea that in applied sporting environments, "fast"-working practitioners should work together with "slow"-working researchers. However, due to economical and logistical constraints, such a coupling may not always be practical. Therefore, alternative means of combining research and applied practice are needed. A particular methodology that has been used in recent years is qualitative research. Examples of qualitative methods include online surveys, 1-on-1 interviews, and focus groups...

BACKGROUND: Despite being a recessive trait, the O blood group is the most frequent worldwide among the ABO blood types. Since running performance has been recognized as a major driver of evolutionary advantage in humans, we planned a study to investigate whether the ABO blood group may have an influence on endurance running performance in middle-aged recreational athletes. METHODS: The study population consisted of 52 recreational, middle-aged, Caucasian athletes (mean age: 49±13 years, body mass index, 23...

PURPOSE: Protein requirements are primarily studied in the context of resistance or endurance exercise with little research devoted to variable-intensity intermittent exercise characteristic of many team sports. Further, female populations are underrepresented in dietary sports science studies. We aimed to determine a dietary protein requirement in active females performing variable-intensity intermittent exercise using the indicator amino acid oxidation (IAAO) method. We hypothesized that these requirements would be greater than current IAAO-derived estimates in nonactive adult males...
