The purpose of this study was to determine if runners who had recently undergone gait retraining altered their running mechanics while performing a cognitive distraction task. Methods: Two groups of runners were analyzed at 3 postintervention time-points for changes in vertical loadrates, cadence, and footstrike pattern. Results: Runners who received cadence retraining (CAD) did not alter cadence, but had increased loadrates when distracted. Runners who received footstrike retraining (FFS) did not alter foot angle or loadrates while distracted. However, both increases and decreases were found in cadence and foot angle in response to distraction. Conclusions: Utilizing a distraction task with gait analyses, especially post-gait retraining, is feasible and recommended.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84515747","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}

Aim: This study, therefore, explored the pattern of MSIs among amateur basketball players in the Anambra State of Nigeria and the correlation between socio-demographic variables and MSIs. Methods: A cross-sectional survey research design was used for this study. One hundred and twelve (112) consenting male basketball players were consecutively recruited for this study. Socio-demographic data was obtained and recorded. Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was used to evaluate MSIs among the participants. Results: The injury proportions of the participants were; the right knee (40.27%), left knee (34.96%), right foot (6.06%), left foot (3.96%), right shoulder (3.64%), right wrist (83.60%) and left wrist (2.93%), lower back (0.99%), Left thigh (0.92%), Left lower leg (0.88%), right thigh (0.71%). MSI had significant moderate correlation with height (r = 0.381, p < 0.01), weight (r = 0.431, p < 0.01) and significant moderate correlation with hours of training per day (r = 0.513, p < 0.01). However, there was no significant correlation between MSIs and Body Mass Index (r = 0.037, p = 0.067) and between MSI and age (r = -0.132, p = 0.167). Conclusion: The pattern of MSIs amongst male amateur basketball players are right knee, left knee, left foot, right foot, right shoulder, right wrist, left wrist, etc. Height, weight, and hours of training per day correlated significantly with MSIs. Age and Body Mass Index (BMI) did not correlate significantly with MSIs. Basketball players should therefore be encouraged to use protective equipment for these parts and physical therapy may help in the prevention and management of MSIs among basketball players.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90044637","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}

Methods: A systematic literature search was performed on electronic databases from inception to 2020. The Cochrane Handbook guidelines for Systematic Reviews of Interventions were used to assess the methodological quality and exclude studies with fatal flaws. The risk of bias was assessed using the Cochrane grading system by two reviewers (SB and BL). Acupuncture intervention was assessed using the Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA). This review is reported according to the PRISMA guidelines. Results: A total of 16 RCTs were included in this review. 8 of the 10 studies that assessed the effect of acupuncture on HR recovery found acupuncture to be significantly more effective than no treatment or sham acupuncture at enhancing recovery HR following exercise. 7 of the 10 studies that assessed the effect of acupuncture on reducing blood lactate found that acupuncture was significantly more effective than no treatment or sham acupuncture at reducing blood lactate following exercise. 4 of the 7 studies that assessed the effect of acupuncture on VO2 max found that there was no significant difference between groups with regards to VO2 max. Conclusion: Our results indicate that there is strong evidence that acupuncture is significantly more effective than sham and control in enhancing recovery HR and blood lactate following intense exercise. However, there is conflicting evidence with regards to the effect of acupuncture on enhancing VO2 max in athletes. Future studies are required that follow the STRICTA guidelines to help determine the effect of acupuncture on enhancing VO2 max in athletes.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90053789","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 objective of this study was to measure the effect of concurrent aerobic-resistance interval exercise on lower leg muscle function and local muscle tissue oxygenation in the vastus lateralis muscle (VLM) of COPD patients. Methods: Peripheral muscle oxygenation in the VLM was measured using Near Infrared Spectrometry (NIRS) during the sixminute walk test (6MWT) in 15 COPD patients: Experimental (EXP., n = 9) and control (CTL., n = 6). Both groups trained for 3 weeks (1 hour/day and 5 days/ week). Training sessions consisted of upper body strength exercises for 20 minutes. Next, the CTL. Group performed 30 minutes of aerobic exercise (motorized treadmill or stationary bike), while the EXP. group completed 30 minutes of aerobic-resistance (concurrent training) interval exercise (non-motorized treadmill). Pre and post-intervention NIRS measurements included oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb), hemoglobin difference (HbDif), total hemoglobin (tHb), and tissue saturation index (TSI). Systemic arterial oxygen saturation (SPO2), heart rate and the rating of perceived exertion with the modified Borg scale were also measured pre and post-intervention during the 6MWT. Results: All patients were able to complete three weeks of training. A significant increase in the 6MWT (51.4%, p < 0.05) distance was noted in the EXP. group and in the VLM HbDiff (69%, p < 0.05). No significant differences were observed in the other muscle oxygenation variables. Conclusion: Concurrent aerobic-resistance interval exercise increases the total distance covered at the 6MWT (increased functional capacity) and muscle oxygen extraction.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87779580","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}

Moreover, to explore a potential correlation of the above-mentioned hormones with stress hormones. Methodology: 30 out of the 40 participants who took part in the race, finished the 246 km in less than 36 hours, and were included in the study. There were 3 different sampling times: prior, after and 48 hours after the race. Blood samples were taken to identify stress and inflammation markers, such as CRP, IL-6 NTproBNP, MBL, troponin, leptin, cortisole and thyroid hormones. Results: CRP, IL-6, SAA, NTproBNP and cortisol showed a dramatic increase after the race, much higher than their initial values, but returned to their initial equilibrium after 48 hours, except SAA which increased further. The behavior of mannose binding lectin with a similar growth trend was similar. Small fluctuations in all the thyroid hormones were observed with initially an increase in the levels, then a downward trend, reaching the initial values again. The only case where the concentration decreased after the race is that of leptin, while troponin concentrations were not detectable. Conclusions: An ultra marathon can be a very stressful event for the body, often elevating hormone levels beyond their normal rate. A significant correlation was observed in the way cortisol changes with CRP, IL-6 and NTroBNP, which reveals the close relationship of the endocrineimmune system in extreme cases of exercise such as that of Spartathlon.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82929208","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}

Design: A convenience sample cohort study of nine volunteer participants (4 males; 5 females) M age 63.4 (± 10.5) years performed both seated (MuV) and standing walking (STW), across 0.5 mph, 1.1 and 1.5 mph velocities. Setting: Institutional, University of Oklahoma Human Performance Laboratory in Tulsa. Participants: Elderly adults with no contra-indications for low speed walking, recruited from the University of Oklahoma staff, faculty and a local YMCA. Main outcome measures: Differences between MuV and STW O2 Consumption (VO2), Rating of perceived exertion (RPE10), and heart rate (HR). Results: Mean HR and VO2 differences between MuV (Seated) and STW (standing) walking at very low intensities were small but statistically significant at p < 0.05. Effect sizes were moderate to high (0.61-0.85) for VO2 at 0.5 and 1.1 mph respectively and low to moderate (0.23-0.61) for HR and RPE for 1.1 mph speed. Conclusions: For people unable to stand or walk, the seated treadmill is a suitable alternative to an upright treadmill. Additional studies in larger and more diverse populations are required in order to confirm this studies initial findings to the general population. Clinical relevance: This form of exercise may have value for those seeking very low intensity (subliminal) exercise while seated at a desk or for those individuals who have a low orthopedic tolerance.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82877356","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}

Studies where sleep was the main variable and included only elite (national or international level), healthy (no injury or any pathology), and adult athletes were included for analysis. Only articles published in the English language were considered. After analyzing all inclusion and exclusion criteria, 50 studies were included. A continental disparity in publications was observed, with a concentration of studies in Oceania and Europe. A total of 2964 athletes were observed, mostly men, and the most studied modality was soccer. As of 2015, actigraphy became the most used method to monitor sleep in athletes, followed by questionnaires and sleep diaries. At no other historical moment has the sleep of the elite adult athlete been so inserted in the scientific area. Elite adult athlete sleep research is an expanding area in sports science and factors such as the elite athlete’s gender and modality, as well as the publication’s instruments and geographic location, will contribute to filling the knowledge gaps in this theme.","PeriodicalId":91298,"journal":{"name":"International journal of sports and exercise medicine","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88504486","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}
