Within the self-determination theory (Deci & Ryan, 2000) framework, research has considered the consequences of coaches' autonomy supportive and controlling behaviors on various athlete outcomes (e.g., motivation and performance). The antecedents of such behaviors, however, have received little attention. Coaches (N = 443) from a variety of sports and competitive levels completed a self-report ...

The software developer of siliconCOACH, a computerized twodimensional video analysis tool for coaches, was assisted to reflect on how his software provided coaches with learning opportunities to understand how coaches and athletes use performance feedback. Our understanding of reflection was informed by the work of Van Manen [9] and Zeichner & Liston [10]. To assist in the reflection process, l...

The study aimed to develop an understanding of female coaches’ and sport science practitioners’ experience support provision in relation the menstrual cycle when working with athletes. Following receipt institutional ethical approval, 14 coaches practitioners (32.9 ± 6.9 years) participated individual semi-structured interviews. analysis, two themes were developed: (1) Knowledge awareness (2) S...

Objectives: The provision of an autonomy-supportive change-oriented feedback has been identified as a crucial coaching behaviour that is beneficial for athletes’ phenomenological experience and performance. Based on past research that focused on the determinants of other autonomy-supportive coaching behaviours, the present study investigates coaches’ passion toward coaching and coaches’ percept...

OBJECTIVE To determine the effectiveness of coach-led neuromuscular warm-up on reducing lower extremity (LE) injuries in female athletes in a mixed-ethnicity, predominantly low-income, urban population. DESIGN Cluster randomized controlled trial. SETTING Chicago public high schools. PARTICIPANTS Of 258 coaches invited to participate, 95 (36.8%) enrolled (1558 athletes). Ninety coaches and...

The current era of internet-facilitated bigger data, better tools, and collective intelligence community computing is accelerating advances in many areas ranging from artificial intelligence to knowledge generation to public health. In the health sector, data volumes are growing with genomic, phenotypic, microbiomic, metabolomic, self-tracking, and other data streams. Simultaneously, tools are ...

BACKGROUND NIATx200, a quality improvement collaborative, involved 201 substance abuse clinics. Each clinic was randomized to one of four implementation strategies: (a) interest circle calls, (b) learning sessions, (c) coach only or (d) a combination of all three. Each strategy was led by NIATx200 coaches who provided direct coaching or facilitated the interest circle and learning session inter...

OBJECTIVE This narrative review summarizes findings for Ironman triathlon performance and intends to determine potential predictor variables for Ironman race performance in female and male triathletes. METHODS A literature search was performed in PubMed using the terms "Ironman", "triathlon", and "performance". All resulting articles were searched for related citations. RESULTS Age, previou...

Purpose: A theory states that strong core stability allows athletes to fully transfer forces from the upper extremities to lower extremities, and finally to the ground. On the contrary, weak core stability causes alterations in transferring forces, reduces sport performance, and increases risk for injury, especially in the lower extremities. Therefore, the current study investigated the relatio...
