AIM To understand how an international rugby coach used questioning behaviours in on-pitch activities during training and competition. METHODS The coach’s behavioural intentions and “coaching philosophy” were investigated through semi-structured interviews. On-pitch coach behaviour was then systematically observed using the Rugby Coach Activities and Behaviours Instrument (RCABI). The RCABI includes behaviour and activity classifications enabling actions to be understood within their micro-contexts. RESULTS Overall, questioning accounted for only 6.34% of on-pitch behaviours; yet, this was the coach’s most frequent direct interaction with players. Time spent questioning varied between activity contexts during training, but was never used during match play. The impacts of intentions, contexts and constraints on questioning behaviour are discussed. CONCLUSION The nuances of questioning behaviour need to be examined in greater depth and with more rugby coaches. It is essential to under...

Extant attentional focus research has largely examined movement tasks that are outcome-focused (e.g., height of jumps, force production, and number of successful turns) with fewer studies of the movement quality or form of an aesthetic discipline (e.g., dance, gymnastics, and ice-skating). In this study, both movement form and outcomebased measures were used to assess the performance of a pirouette. Thirteen skilled dancers performed pirouettes on a force plate under three trial conditions: control (no focus instruction), external focus instruction, and internal focus instruction. Assessment of the dancers' performance was quantified by 1. variability of postural sway, 2. duration of balance sustained, and 3. quality of movement form as rated by four experienced dance teachers. To corroborate the quantitative findings, dancers' perspectives were included in the study. Statistical analysis showed that the quality of a pirouette under the influence of external or internal focu...

Establish current practice and attitudes towards recovery in a group of Division-1 Collegiate athletes from North America. A 16-item questionnaire was administered via custom software in an electronic format. 152 student athletes from a Division-1 Collegiate school across 3 sports (Basketball, American Football, Soccer). The approaches and attitudes to recovery in both training and competition. Sleep, cold water immersion (CWI) and nutrition were perceived to be the most effective modalities (88, 84 and 80% of the sample believed them to have a benefit respectively). Over half the sample did not believe in using compression for recovery. With regard to actual usage, CWI was the most used recovery modality and matched by athletes believing in, and using, the approach (65%). Only 24% of student athletes believed in, and used, sleep as a recovery modality despite it being rated and perceived as the most effective. Collectively, there is a discrepancy between perception and use of recov...

The global prevalence of childhood and adolescent obesity is high. Lifestyle changes towards a healthy diet, increased physical activity and reduced sedentary activities are recommended to prevent and treat obesity. Evidence suggests that changing these health behaviours can benefit cognitive function and school achievement in children and adolescents in general. There are various theoretical mechanisms that suggest that children and adolescents with excessive body fat may benefit particularly from these interventions. To assess whether lifestyle interventions (in the areas of diet, physical activity, sedentary behaviour and behavioural therapy) improve school achievement, cognitive function (e.g. executive functions) and/or future success in children and adolescents with obesity or overweight, compared with standard care, waiting-list control, no treatment, or an attention placebo control group. In February 2017, we searched CENTRAL, MEDLINE and 15 other databases. We also searched...

Assess current practice and attitudes towards recovery in adolescent athletes. Questionnaires were administered either via print or online questionnaire. Athletes and coaches from within Asia were surveyed (n = 112 & 53), with a comparative sample in the UK (n = 53 & 8). The approaches and attitudes to recovery in both training and competition. Adolescent athletes perceive a variety of recovery modalities as important, though prioritise active recovery, nutrition and sleep. Attitudes towards recovery differed between athletes in Asia and the UK with respect to the perceived benefits of: sleep (96% believe in it in the UK v 69% in Asia, p < 0.01); nutrition (92 v 58%, p < 0.01); and active recovery (70 v 52%, p = 0.03). The number of recovery techniques used with Asian athletes was higher after training (p = 0.009) and competition (p < 0.01). Asian athletes rely more on 'feel' to justify interventions. There was a major disconnect amongst athletes' belief in part...

Physiotherapists and other practitioners commonly prescribe foam rolling as an intervention, but the mechanistic effects of this intervention are not known. The aim of this investigation was to establish if a single bout of foam rolling affects flexibility, skeletal muscle contractility and reflected temperature. Twelve adolescent male squash players were evaluated on two separate occasions (treatment and control visits) and were tested on both legs for flexibility of the hip flexors and quadriceps, muscle contractility (as measured by tensiomyography) and temperature of the quadriceps (assessed via thermography) at repeated time points pre- and post a 60s rolling intervention (pre-, immediately post, 5, 10, 15, and 30 minutes post). They rolled one leg on the treatment visit and did not perform rolling on the control visit. The main outcome measure was the flexibility of hip flexor and quadriceps at repeated time points up to 30 minutes post intervention. The average foam rolling f...

This paper examines paternalism through the political development of sport and physical education in post-colonial Singapore. Initial consideration is given to demography, post-WWII development, prevailing political ideology, economic factors and the social characteristics of Singaporeans. Through the stewardship of the current Prime Minister, Mr Goh Chok Tong, elite sport in Singapore has only recently been accepted by the government as

There is a growing body of research on the influence of ingesting carbohydrate-electrolyte solutions immediately prior to and during prolonged intermittent, high-intensity exercise (team games exercise) designed to replicate field-based team games. This review presents the current body of knowledge in this area, and identifies avenues of further research. Almost all early work supported the ingestion of carbohydrate-electrolyte solutions during prolonged intermittent exercise, but was subject to methodological limitations. A key concern was the use of exercise protocols characterized by prolonged periods at the same exercise intensity, the lack of maximal- or high-intensity work components and long periods of seated recovery, which failed to replicate the activity pattern or physiological demand of team games exercise. The advent of protocols specifically designed to replicate the demands of field-based team games enabled a more externally valid assessment of the influence of carbohydrate ingestion during this form of exercise. Once again, the research overwhelmingly supports carbohydrate ingestion immediately prior to and during team games exercise for improving time to exhaustion during intermittent running. While the external validity of exhaustive exercise at fixed prescribed intensities as an assessment of exercise capacity during team games may appear questionable, these assessments should perhaps not be viewed as exhaustive exercise tests per se, but as indicators of the ability to maintain high-intensity exercise, which is a recognized marker of performance and fatigue during field-based team games. Possible mechanisms of exercise capacity enhancement include sparing of muscle glycogen, glycogen resynthesis during low-intensity exercise periods and attenuated effort perception during exercise. Most research fails to show improvements in sprint performance during team games exercise with carbohydrate ingestion, perhaps due to the lack of influence of carbohydrate on sprint performance when endogenous muscle glycogen concentration remains above a critical threshold of ∼200  mmol/kg dry weight. Despite the increasing number of publications in this area, few studies have attempted to drive the research base forward by investigating potential modulators of carbohydrate efficacy during team games exercise, preventing the formulation of optimal carbohydrate intake guidelines. Potential modulators may be different from those during prolonged steady-state exercise due to the constantly changing exercise intensity and frequency, duration and intensity of rest intervals, potential for team games exercise to slow the rate of gastric emptying and the restricted access to carbohydrate-electrolyte solutions during many team games. This review highlights fluid volume, carbohydrate concentration, carbohydrate composition and solution osmolality; the glycaemic index of pre-exercise meals; fluid and carbohydrate ingestion patterns; fluid temperature; carbohydrate mouthwashes; carbohydrate supplementation in different ambient temperatures; and investigation of all of these areas in different subject populations as important avenues for future research to enable a more comprehensive understanding of carbohydrate ingestion during team games exercise.
