Since the introduction of \"Classic\" powerlifting by the International Powerlifting Federation (IPF) in 2012, there has been an increase in popularity, athlete participation, and attention from sports science research. Previous studies have examined factors influencing the long-term longitudinal adaptation of upper- and lower-body strength, but no one used this information to develop predictive models of future classic powerlifting performances, especially considering the different age, sex, and weight categories, with the final aim of tailoring the medium- and long-term training goals. This study aims to develop and validate a machine learning-based linear regression model to predict single-lift and overall performance in classic powerlifters.

Studies were included if they met the Population, Intervention, Comparison, and Outcome (PICO) criteria, were of English language, peer-reviewed, full-text original articles, and using human participants.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Forty-three studies investigated the effects of hot yoga (both acute and/or chronic), totalling 942 participants (76% female). The most common method of yoga performed in hot conditions was Bikram (74%), followed by generalised hot yoga (19%), Hatha (5%) and then Vinyasa (2%). Typical session duration ranged 20-90 min and occurred within 30-52 °C and 20-60% relative humidity. Hot yoga training interventions consisted of 6-36 sessions, that were completed 2-6 times per week, over 1-16 weeks. Acute hot yoga increased body temperature and heart rate, but not the energetic demands when compared to other forms of non-heated yoga. Chronic hot yoga appeared to elicit cardiometabolic (e.g. body composition, lipid profiles and macrovascular function) and functional adaptations applicable for health (e.g., bone mineral density, balance and flexibility) as well as physical performance (e.g., submaximal exercise thresholds). Adaptations appear to occur without negatively impacting kidney function or sleep quality across healthy, sedentary and athletic populations. Hot yoga also presents promising, albeit inconclusive findings concerning the alleviation of psychological and affective disorders, and optimising markers of cognitive function. However, caution is advised as case studies report ill-health following hot yoga practice. Some literature lacks rigorous, high-quality experimental designs and sophisticated measurements that allow for mechanistic investigation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Investigations into hot yoga demonstrate intriguing health and functional benefits. However, claims that hot yoga provides greater health benefits than other forms of yoga or traditional exercise are at present unsubstantiated. Studies describing beneficial effects of hot yoga often do not utilise robust experimental designs or methods that facilitate mechanistic insights. Hot yoga warrants further investigation as a tool to improve health and wellbeing.

Birth dates were extracted from public databases to calculate numerical relative age (n = 2211 players). Biological maturity timing was defined as the z-score of the percentage of adult height (z%AH) reached at term 1 (~ 16 years of age). Retrospective longitudinal data on selection to junior national teams (U16, U18, U20) and the National Hockey League (NHL) were retrieved from open databases. Junior and adult success probabilities were modelled using generalised logistic modelling (GLM). Spearman correlation analysis was used to assess the correlation between the anthropometric data, relative age, and biological maturation. In addition, the predictor z%AH was added to the GLMs to characterise interactions.</p><p><strong>Results: </strong>Individuals with a higher relative age were overrepresented in Swedish ice hockey programmes. Players born between January and March (Q1) were about twice as likely to reach the U16 national team as players born between October and December (Q4). Consequently, in a GLM, relative age was identified as a significant predictor of junior success. The addition of z%AH improved model fit for U16 selection, and an interaction between z%AH and RA was observed (p < 0.05). In contrast, relative age was not a significant predictor of reaching the NHL (p = 0.21). There was no interaction between the RA and z%AH (p = 0.44) for adult success. When cross-tabulated, the players most likely to reach both the NHL and the U16 national team were either born early and matured late or born late and matured early.</p><p><strong>Conclusion: </strong>Early-born and early-maturing players in certified Swedish high school programmes are more likely to be selected for the U16 national team. In terms of adult success, RA had no significant effect on the likelihood of playing in the NHL. However, in a combined model, regardless of relative age, players with late biological maturity timing were more likely to reach the NHL.</p>","PeriodicalId":21788,"journal":{"name":"Sports Medicine - Open","volume":"11 1","pages":"102"},"PeriodicalIF":5.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12417341/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145024191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
