Options available to increase the potency of this exercise to promote training adaptations are generally limited to manipulation of speed, gradient, and duration. However, emerging studies have suggested that blood flow restriction (BFR) combined with walking is a method that can accentuate training-induced adaptations compared with walking alone. This narrative review aimed to examine the effectiveness and safety of BFR walking in older adults according to the existing literature. Of the limited evidence available on this topic, it appears that BFR walking compared with walking alone can induce significant increases in muscular hypertrophy and strength. Therefore, implementing BFR walking may be a feasible and safe option for older adults to enhance the effectiveness of their walking interventions, at least from a musculoskeletal perspective.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135352144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major limitation of current approaches to performance support is they unduly constrain the conceptualization of high performance within precise boundaries. In contrast, we explore the notion of parallel incrementalism to guide the pursuit and support of athletic excellence. Given this context, we introduce the idea of performance-limiting factors (PLFs) to complement key performance indicators (KPIs) in informing performance support. Whereas KPIs directly influence or describe performance, PLFs are characteristics that indirectly affect performance in their current state. Considering human performance through the complex interaction of KPIs and PLFs will allow us to continue pushing the boundaries of high-performance sport.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135579254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The good morning may be particularly beneficial for lifters with lower levels of grip strength or upper-limb injury, which may prevent using a clean or opposing grip.

This effort has been less pronounced with first responders (police, firefighters, emergency services), despite the structured academy training typically completed by recruits, challenging job tasks and long-term health, fitness, and wellness concerns. One example of how sports science practices could be applied for first responders is through high-performance programs. High-performance programs are commonplace within elite sport and can help set roadmaps for success. Numerous factors contribute to an effective program, much of which relates to the resources provided to personnel. This can include a multidisciplinary team (e.g., strength and conditioning coaches, athletic trainers/medical staff, psychologists, nutritionists, researchers) and appropriate resources (e.g., gyms, facilities, testing and training equipment). This review will discuss whether high-performance programs, or at least components of these programs, could be adopted in first-responder populations. The authors will discuss literature to demonstrate how and why high-performance programs could be implemented for first responders and whether these programs are aspirational, attainable, or objectionable. Finally, the authors will provide actionable high-performance program-related information for the strength and conditioning coach and tactical scientist working with first responders.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136099031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of the 1,304 articles screened, 24 met the inclusion criteria. Of the included studies, 13 reported on the anthropometric and physiological measures of 4-wheeled racing athletes from both open and closed-wheel disciplines. The remaining 11 studies reported on the physiological profiles of 2-wheeled racing athletes from both on-road and off-road riding disciplines. Open-wheel racers have greater cardiopulmonary fitness than close-wheel racers, as well as greater strength throughout movements of neck lateral flexion and isometric knee extension. Close-wheel racers were shown to be heavier with greater fat mass than the open-wheel racers but exhibited greater isometric shoulder flexion and plantarflexion strength. Female 2-wheeled racers were also shown to have a weaker handgrip strength than their male counterparts.

Of those who responded, 20% of coaches were female, 57% obtained their master's degree, and 85% completed a degree in an exercise-related field. Regarding salary, the average income for strength and conditioning coaches increased since 2018. In 2022, average earnings by market ranged from $60,527 to $84,575. The highest average salary and highest total salary belonged to coaches working in professional sports. Salary trends demonstrated that higher education, years of experience, senior positions, and working in a higher professional league influenced higher earning potential.

ABSTRACT The effects of caffeine mouth rinse (Caff-MR) on sports performance have been evaluated by recent studies presenting contrasting results. Therefore, this systematic review aimed to summarize the evidence regarding the effects of Caff-MR on sports performance. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations, the search through PubMed, Web of Science, and Scopus databases was performed until December 2021. A random-effects meta-analysis of standardized mean differences was performed to assess the overall effect of Caff-MR on sports performance-related outcomes. Sixteen studies met the inclusion criteria (207 participants). The meta-analysis showed no significant overall effect of Caff-MR on sports performance (p = 0.09). Moreover, no effects were shown on maximal heart rate or ratings of perceived exertion. The risk of bias for the included studies assessed using the risk of bias in randomized trials Cochrane tool presented 87.5% (n = 14) of the studies as medium and 12.5% (n = 2) as high scores. These data do not support using Caff-MR for sports performance, although more consistent and well-controlled studies are warranted. Large heterogeneity in study designs precludes making practical recommendations for exercise performance. More research is warranted to elucidate the potential of Caff-MR, specifically focusing on determining the optimal dose.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"45 1","pages":"617 - 627"},"PeriodicalIF":2.5,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44366237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can help decrease resting BP at least as much as aerobic or dynamic resistance training. IRT can be as effective as one antihypertensive medication and likely lessens strokes and myocardial infarctions. It can be as safe as other exercise modes regarding acute BP rise and safer than aerobic exercise regarding cardiac demand. Grip IRT is currently more conducive than leg IRT to program delivery.
