It focuses on distinct aspects of female physiology with an oriented discussion following the reproductive life stages of healthy, eumenorrheic females, including premenopausal time frames, pregnancy, perimenopause, and menopause. Finally, this review aims to address methodological challenges surrounding sexual dimorphism in energy metabolism investigations and confounding factors in this field. During resting conditions, females tend to have higher rates of non-oxidative free fatty acid clearance, which could contribute to lower respiratory exchange ratio measures. At the same time, carbohydrate energy metabolism findings are mixed. In general, females favor lipid energy metabolism during moderate-intensity exercise, while men favor carbohydrate energy metabolism. Factors such as age, dietary intake, genetics, and methodological decisions confound study findings, including properly identifying and reporting the menstrual cycle phase when female subjects are eumenorrheic. Pregnancy presents a unique shift in physiological systems, including energy metabolism, which can be observed at rest and during exercise. Changes in body composition and hormonal levels during the post-menopausal period directly impact energy metabolism, specifically lipid metabolism. This change in physiological state factors into the evidence showing a reduction in our understanding of sex differences in lipid metabolism during exercise in older adults.

However, in recent years, both players and practitioners have started to recognise the value of a fitter and healthier body, owing to its potential positive impacts on performance, namely clubhead speed (CHS).</p><p><strong>Objective: </strong>The aim of this meta-analysis was to examine the associations between CHS (as measured using a driver) and a variety of physical characteristics.</p><p><strong>Methods: </strong>A systematic literature search with meta-analysis was conducted using Medline, SPORTDiscus, CINAHL and PubMed databases. Inclusion criteria required studies to have (1) determined the association between physical characteristics assessed in at least one physical test and CHS, (2) included golfers of any skill level but they had to be free from injury and (3) been peer-reviewed and published in the English language. Methodological quality was assessed using a modified version of the Downs and Black Quality Index tool and heterogeneity assessed via the Q statistic and I<sup>2</sup>. To provide summary effects for each of the physical characteristics and their associations with CHS, a random effects model was used where z-transformed r values (i.e. z<sub>r</sub>) were computed to enable effect size pooling within the meta-analysis.</p><p><strong>Results: </strong>Of the 3039 studies initially identified, 20 were included in the final analysis. CHS was significantly associated with lower body strength (z<sub>r</sub> = 0.47 [95% confidence intervals {CI} 0.24-0.69]), upper body strength (z<sub>r</sub> = 0.48 [95% CI 0.28-0.68]), jump displacement (z<sub>r</sub> = 0.53 [95% CI 0.28-0.78]), jump impulse (z<sub>r</sub> = 0.82 [95% CI 0.63-1.02]), jumping peak power (z<sub>r</sub> = 0.66 [95% CI 0.53-0.79]), upper body explosive strength (z<sub>r</sub> = 0.67 [95% CI 0.53-0.80]), anthropometry (z<sub>r</sub> = 0.43 [95% CI 0.29-0.58]) and muscle capacity (z<sub>r</sub> = 0.17 [95% CI 0.04-0.31]), but not flexibility (z<sub>r</sub> = - 0.04 [95% CI - 0.33 to 0.26]) or balance (z<sub>r</sub> =  - 0.06 [95% CI - 0.46 to 0.34]).</p><p><strong>Conclusions: </strong>The findings from this meta-analysis highlight a range of physical characteristics are associated with CHS. Whilst significant associations ranged from trivial to large, noteworthy information is that jump impulse produced the strongest association, upper body explosive strength showed noticeably larger associations than upper body strength, and flexibility was not significant. These findings can be used to ensure practitioners prioritise appropriate fitness testing protocols for golfers.</p>","PeriodicalId":21969,"journal":{"name":"Sports Medicine","volume":null,"pages":null},"PeriodicalIF":9.3,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11239735/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139997443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
