This study examined the test–retest reliability of corticospinal excitability in the upper extremity musculature of 21 healthy individuals using transcranial magnetic stimulation. Within-session reliability was assessed by comparing tests performed 120 minutes apart. Between-session reliability was assessed by comparing the second (24 hr), third (1-week), and forth (2-week) sessions to the first test. We recorded active motor threshold (AMT) and motor evoked potential (MEP) at 120% AMT of the upper trapezius (UT), middle deltoid (MD), and flexor carpi radialis (FCR) bilaterally. Intraclass correlation coefficients (3,1) were used to assess relative reliability, and minimal detectable changes at 95% confidence level were calculated to assess absolute reliability. Our results suggest that AMT of the MD and FCR demonstrated acceptable within-session and between-session reliability over 24 hours, with all muscles evaluated ranging from moderate to good over 2 weeks. In contrast, MEP amplitudes were less reliable for all muscles, with reliability point estimates ranging from poor to moderate. AMT appears to be a more consistent measure of corticospinal excitability in upper extremity musculature, which may be more appropriate in clinical outcomes research.","PeriodicalId":48577,"journal":{"name":"Measurement in Physical Education and Exercise Science","volume":"27 1","pages":"73 - 84"},"PeriodicalIF":2.1,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46047064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirteen males (24.1 ± 3.8 years, 79.3 ± 14 kg, 179 ± 6.6 cm) participated. Bicep femoris long head (BFLH) US images were collected on two separate occasions. Three previously established extrapolation methods were utilized. Near-perfect reliability was observed for all methods. Criterion estimation resulted in a significant, trivial (p = 0.016,g = 0.17) increase in FL compared to the basic trigonometry equation with non-significant, trivial increase (p = 0.081,g = 0.10) between the criterion and partial measure method. The partial measure method was not significantly or meaningfully greater than the basic trigonometry method (p = 0.286,g = 0.08). Both alternative methods demonstrated unacceptable LOA (>5%), with heteroscedasticity. All methods of extrapolation are reliable and could be used over time. However, as methods are not comparable, there could be a rationale to utilize underestimated results to ensure a degree of cushioning.","PeriodicalId":48577,"journal":{"name":"Measurement in Physical Education and Exercise Science","volume":"27 1","pages":"43 - 50"},"PeriodicalIF":2.1,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45245796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three statistical approaches – confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), and item response theory analysis (IRT) – were applied to the data collected from 88 participants aged 9–12 years. Furthermore, 10 of them were randomly selected to examine the test–retest reliability by calculating intraclass correlation coefficients (ICC). The synthesis of findings from CFA, ESEM, and IRT analyses provides supportive evidence that two- and bi-factor structures demonstrated better model-data fit compared to the one-factor structure. An excellent level of test–retest reliability was confirmed in the TAMS (ICC = .96) and anthropometric instruments (ICC = .986–.998). We conclude that a composite score derived from the TAMS is sufficient and practical to measure one’s general competence in advanced movement skills during late childhood.","PeriodicalId":48577,"journal":{"name":"Measurement in Physical Education and Exercise Science","volume":"27 1","pages":"21 - 31"},"PeriodicalIF":2.1,"publicationDate":"2022-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47501366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The following equation provides accurate and feasible estimates of VJ power (Watts) = −1354.820 + (35.455*VJ[cm]) + (43.942*body mass[kg]).
