Weekly vitamin D₃ supplementation improves aerobic performance in combat sport athletes

Vitamin D3 supplementation can affect the strength and power of an athlete, however the effect on endurance performance remains unclear. Twenty-seven recreational male combat athletes with at least 12 months experience within combat sports were recruited (age: 24 ± 4 years, stature: 176 ± 6 cm, weight: 77 ± 14 kg). Participants completed baseline testing for blood haemoglobin and haematocrit, upper and lower body VO2peak and upper and lower body Wingate. Following testing participants were stratified to 50000IU (D1), 80000IU (D2) or 110000IU (D3) of vitamin D3 per week. They then completed a 6-week placebo period followed by a 6-week supplementation period. Retesting was carried out after the placebo and supplementation period. There was a significant effect for time for haemoglobin and haematocrit, upper and lower body VO2peak and upper body Wingate power (p<0.01) but no effect for dose of vitamin D given. Performance data was normalised to vitamin D intake and there was a moderate effect size between D1 and D2 for lower body VO2peak (d=0.6), upper body VO2peak (d=0.13) and upper body average power (d=0.75), with a large effect size between D1 and D2 for haemoglobin (d=1.19), haematocrit (d=0.93) and upper body peak power (d=0.95). There was a large effect size for D1 compared to D3 for all variables (d>0.8). Therefore, there is no additional benefit to increasing dose above 500000IU vitamin D per week. Given the endurance adaptations from vitamin D supplementation and the importance of endurance for combat performance, recreational combat athletes should supplement at 50000IU per week for six weeks

Facing up to binge drinking: Reducing binge drinking in adolescent males

Objective: To evaluate the effectiveness of an oro-facial trauma-based brief intervention, designed to raise adolescent males’ awareness about the immediate dangers of binge drinking.Design: Non-randomised controlled exploratory trialSetting: Secondary level schoolsMaterials & Methods: Pre, post and follow up validated questionnaires were used to assess a variety of descriptive data and changes in behaviour. Sixty Year 12 students were recruited in the pilot study and 182 in the definitive study.Intervention: A brief visual presentation containing salient information and anonymised photographs relating to oro-facial injuries.Main Outcome Measures: Intention to binge drink.Results: The majority of participants obtained alcohol from off-license or licensed premises. At the commencement of the study, 68% of the participants were regular drinkers. Whilst there was no change in drinking behaviour, the intervention group reported that it was significantly more likely (compared to the control group) that they would reduce their drinking to less than binge levels.Conclusion: The intervention resulted in participants reporting a more negative attitude towards binge drinking and increased their intention to disengage from binge drinking

Professional Baseball Athletic Trainers\u27 Perceptions of Preparation for Job-Specific Duties

Context The extent to which individuals are prepared completely for work in a particular athletic training setting (eg, professional sports, college, high school) is unknown. This issue is critical today, and findings in this area have implications for athletic training education policy and employers. Objective To determine the perceptions of preparation for work-specific tasks by professional baseball athletic trainers (PBATs). We also wanted to determine whether various preparation experiences interact with perceived skills. Design Cross-sectional study. Setting Online survey administered via SurveyMonkey. Patients or Other Participants Two hundred seventy-five PBATs. Intervention(s) The PBATs reported their levels of preparation before employment in their positions and their current skills in each of the 8 work task domains: evaluation of elbow injuries; evaluation of shoulder injuries; evaluation of general injuries; acute care; injury prevention; treatment, rehabilitation, and reconditioning; organization and administration; and non–athletic-training tasks. Main Outcome Measure(s) Nine repeated-measures analyses of covariance were performed with each perception of preparation (retrospective, current) as a within-subject factor. Preparation experiences were included as between-subjects factors, and number of years working in baseball was the covariate. Results Subscale reliabilities were calculated and found to be between 0.79 and 0.97. A total of 180 PBATs (65%) completed the survey. The backgrounds and routes by which PBATs gained employment in the professional baseball setting varied. Individuals who completed professional baseball internships, had previous work experience, and immediately entered the professional baseball setting after graduation had noted differences in their perceptions of preparation for work tasks. The PBATs indicated they were substantially underprepared for tasks in the organization and administration and non–athletic-training task domains. Conclusions The organizational socialization process is complex, and no 1 experience appears to completely prepare an individual for work in the professional baseball setting. </jats:sec
