Two primary objectives of the study sought to: 1) Further establish understanding of the mechanisms behind using carbohydrate mouth rinsing to enhance performance and 2) Provide additional support for particular unidentified oral receptors. Male and female University students (n=24) completed four experimental trials where solutions were mouth rinsed for 30 seconds (three x 10 seconds) prior to electroencephalogram (EEG) and affective picture processing (APP) testing. The solutions included water, taste-matched artificial sweetener, taste-matched and artificially sweetened maltodextrin, and taste-matched glucose. Following the rinsing bouts, participants viewed and categorized 60 randomized pictures (30 positive and 30 neutral) while late positive potential (LPP) EEG amplitudes and latencies were amassed for future analysis. After omitting four outliers, the midline-electrode Fz produced statistically significant (p=0.03) results when sorting and analyzing each solution independently for the positive and neutral picture sets. The relative difference between the positive and neutral LPP amplitudes as a function of solution was least pronounced for artificial sweetener (positive=-0.87 μV, neutral=-1.17 μV) and most clearly differentiated for maltodextrin (positive=-0.37 μV, neutral=-1.62 μV). The current study supports and augments previous research that suggests carbohydrate mouth rinsing utilizes central mediated mechanisms to enhance athletic performance. Additionally, the superior LPP activity exhibited by maltodextrin further supports the potential existence of an unidentified receptor within the oral cavity.","PeriodicalId":90574,"journal":{"name":"Journal of athletic enhancement","volume":"401 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84851591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, soccer players use lower body movements as cues, while volleyball players use upper body movements as cues. Despite differences in these focal points, both groups of players use specific cues to recognize sport-specific situations, based on sports-specific experience. This paper aims to investigate how sports-specific knowledge and experience affect reaction times associated with anticipation and prediction by comparing responses during simple and complex tasks performed by athletes with different backgrounds (soccer and volleyball). \u0000 \u0000Methods: Twenty-six collegiate male soccer players (20.0 ± 0.77 years) and twenty-one collegiate male volleyball players (19.8 ± 0.98 years) completed video-based single direction (SDRT) and multiple direction (MDRT) reactive agility test trials. Participants reacted to a soccer pass that was executed by the model in the video. Both groups completed a questionnaire about the reaction cue used. A two-factor mixed analysis of variance, with the withinfactor as “Tasks” (i.e., SDRT, MDRT) and the between-factor as “Sports” (i.e., Soccer, Volleyball), analyzed the main effects and interactions. The generalized η2 was used to compare the withinand between-factors, and Cohen’s d was used to compare the effect size between groups. For the questionnaire, a chi-square test of independence was used. \u0000 \u0000Results: The time from presentation of the stimulus to the time when the participant started to move was shorter in the simple task condition (i.e., SDRT; p<0.01), and for more experienced soccer players (p<0.01). The generalized η2 was larger in the betweenfactor “Sports” than the within-factor “Tasks.” The Cohen’s d between tasks was greater in the volleyball group than the soccer group. No significant differences in the questionnaire responses were found between sports groups. \u0000 \u0000Conclusion: These results suggest that sport-specific experience affects reaction times in the premotor phase.","PeriodicalId":90574,"journal":{"name":"Journal of athletic enhancement","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85598940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirteen competitive swimmers underwent a 6-week, double-blind placebo-controlled study, ingesting 4.8 g.day-1 of β-alanine or placebo. Before and after the supplementation period, the total anaerobic contribution (TAn) and 30 s all-out tethered swimming effort (30TS) were assessed. Anaerobic alactic (AnAl) and lactic energy (AnLa) was assumed as the fast component of excess post-exercise oxygen consumption and net blood lactate accumulation during exercise (Δ[La-]), respectively. Aerobic contribution (Aer) was determined by the difference between total energy demand and TAn. In addition to conventional statistical analysis (MANOVA; p>0.05), a magnitudebased inference analysis was used. No significant group and time effects were observed with MANOVA analysis. Qualitative inference for substantial changes produces by β-alanine supplementation demonstrated: a possibly negative effect of absolute anaerobic AnLa (2/23/74): likely negative effect on percentage of AnAl (1/4/94), Δ[La] (3/16/81) and impulse obtained in 30TS (3/18/79); and very trivial effect to 400 m performance (7/89/5). Thus, the results demonstrated that β-alanine supplementation changed metabolic contribution with a decrease in glycolytic contribution; however, it did not improve performance during 400 m freestyle.","PeriodicalId":90574,"journal":{"name":"Journal of athletic enhancement","volume":"51 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86474650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A convenience sample of 16 amateur male combat athletes with at least two years combat training experience were assigned to either a strength and power training program (SPT, n=10) or control group (CT, n=6). Both groups performed three weekly combat training sessions for six weeks. The SPT group performed two sixty-minute SPT sessions in addition to usual combat training. The following variables: leadhand jab, rear-hand cross, front kick and roundhouse kick mean impact power, vertical jump height, and five-repetition maximum (5RM) half-squat and bench press, were measured using standard protocols at baseline and after six weeks. Magnitude-based inferences (Cohen’s d (d) ± 90% CI) revealed likely beneficial effects of SPT on cross punch (d=0.69 ±0.76), roundhouse kick power (d=0.86 ± 0.83), and vertical jump (d=0.53 ± 0.66). Benefits of usual combat training were unclear for all measured parameters. When between-group changes across the six-week period were compared SPT demonstrated likely benefits for cross-punch (d=0.75 ± 0.80) and 5RM half-squat (d=0.81 ±0.78) compared to usual combat training. These data suggest the addition of SPT to combat training may have a beneficial effect on cross-punch impact power and 5RM half-squat strength in amateur male combat athletes.","PeriodicalId":90574,"journal":{"name":"Journal of athletic enhancement","volume":"12 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76680767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is an inherent risk of injury when participating in these activities. The majority of published research has described winter sport injuries that have occurred at major ski areas. Purpose: This study identified injury occurrence and trends among winter sports participants at a small ski area (SSA) in the Upper Midwest. Study design: Multi-year, retrospective study. Methods: Injury reports compiled over eight seasons (2006-14) by National Ski Patrol staff at this SSA were examined. Results: There were 1,200 reports that met the inclusion criteria. The average age of injured SSA guests was 16.0 ± (7.7) y, while the ratio of injured male to female guests was 2.2:1. Experience level was documented in 1,035 injury reports (86%), among which 46% of guests classified themselves as novices/beginners. Conclusion: Injuries were more likely to occur in the evening. Fractures, sprains/strains, bruises and concussions were the most common type of injury among all guests. Snowboarding accounted for the greatest number of overall injuries; though a disproportionately higher number of injuries, based on estimated use, occurred at the SSA's terrain park. Injury rates were reduced throughout the study period, dropping from 5.02 injuries/1,000 guests in 2006-07 to 2.64 injuries/1,000 guests in 2013-2014. Clinical relevance: Knowledge of snow sport injury characteristics at SSAs may help management, National Ski Patrol (NSP) members and sports medicine professionals create staffing plans and emergency procedures that best protect the health and safety of their snow sport guests.","PeriodicalId":90574,"journal":{"name":"Journal of athletic enhancement","volume":"38 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83713905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of scapular dyskinesis has been shown to result in 43% increase in shoulder pain in athletes. It is known that peripheral ES changes muscle behavior. There are no studies that examine exercise with triggered ES to the lower trapezius, to address shoulder pain and scapular dyskinesis. \u0000 \u0000Methods: The purpose of this case study was to demonstrate that specific parameters with triggered ES, combined with 3 exercises, would result in meaningful improvement in shoulder function and pain in a 22-year-old powerlifter with chronic shoulder pain and scapular dyskinesis. The patient received 6 treatments of trigger switch cued ES and exercise plus four manual therapy sessions. A biphasic-pulsatile current was used. The frequency and pulsewidth were 25 pps and 250 usec, respectively. The intensity was comfortable and produced scapular retraction. \u0000 \u0000Results: Improvements were noted in all outcomes. Numeric Pain Rating Scale was decreased to 1/10. Left shoulder passive range of motion was returned to 100%. The Quick Dash Disability score improved from 38.6% to 2.27%. The Quick Dash Work Module score improved from 6.6 to 0, the Quick Dash Sport Module score improved from 37.5 to 0. The Patient Specific Functional Scale score improved from 3.7 to 8.3. Thoracic spine to scapula distance differences occurred at the following shoulder abduction angles: -0.7 cm at 0, -0.1 cm at 45, +0.4 cm at 90, and -0.5 cm at 120. \u0000 \u0000Conclusion: Trigger switch ES and 3 exercises, plus traditional manual therapy, resulted in improvement in all self-report outcome measures and a change in thoracic spine to scapula distance in a patient with shoulder pain and scapular dyskinesis who had failed to improve by traditional physical therapy.","PeriodicalId":90574,"journal":{"name":"Journal of athletic enhancement","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88909693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
