Through practice and proper instruction, pitchers can refine their pitching mechanics to maximize efficiency and throwing velocity in tandem with improving injury resistance. Non-specific training such as gym-based resistance training has been used concurrently with baseball skills training to enhance athletic abilities, including throwing velocity. Increases in throwing velocity have been observed while training with lighter (greater than 12 repetition maximum [RM]) and heavier (3–12 RM) loads. Specific training such as variably weighted baseballs has also been utilized to facilitate increases in throwing velocity. Throwing velocity has also been successfully increased using balls overweight and underweight than the standard five-ounce baseball. More clarity is needed regarding necessary strength levels, range of motion, and progressions in ball mass or throwing volume when applying this training mode. Training methods to increase throwing velocity in baseball athletes should include resistance training with a variety of loads and throwing variably weighted baseballs within the athlete's capability.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":" ","pages":"1 - 9"},"PeriodicalIF":2.5,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49174303","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}

Twenty-four studies were included from 3 electronic databases. The results showed that the RT protocols with medium ECC MAD and fast CON MAD, specifically cadences 2–4/0/1/0, produced the highest improvement values for the development of maximum dynamic strength, both in trained (18–24%) and untrained subjects (10–14%). For the development of maximum power, a medium total repetition MAD of less than 4 seconds and slow total repetition MAD, less than 8 seconds, seems suitable for untrained and trained subjects, respectively, with the condition that CON MAD is explosive or fast (cadence 4–8/0/max-3/0). Finally, muscle hypertrophy could be improved with a total repetition MAD less than 8 seconds in both trained and untrained subjects. The optimal timing of each muscle action to maximize hypertrophic training results is still not entirely clear. In conclusion, the prescription of the MAD, total and phase specific, should be planned according to the adaptations desired in untrained and trained individuals.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"44 1","pages":"39 - 56"},"PeriodicalIF":2.5,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42777291","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}

Therefore, this review aims to examine the manipulation of ST variables (i.e., load intensity, number of sets and repetitions, exercise order, and rest interval length) on BP and HRV after a session and a long-term program. The BP reduced significantly after an ST session independently of the load intensity, the number of sets and repetitions, the rest interval length, the mode, and the participant characteristic (healthy patients or patients with chronic disease). However, a high number of sets and repetitions, prioritizing multijoint exercises, with longer rest interval lengths between sets and exercises may potentiate these effects. In the HRV analyses, most of the trials showed a sympathetic predominance after an ST session. Hence, it is reasonable to confirm that central adjustments are responsible to control hemodynamics after an ST session.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"44 1","pages":"38 - 61"},"PeriodicalIF":2.5,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43186553","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}

ABSTRACT High-speed running (HSR) has been documented within rugby league to differentiate playing standard and position and often precedes pivotal match events. Practitioners and researchers place importance on HSR because of its inclusion in assessing the demands of training and match play to help prescribe accurate training loads and recovery methods. HSR can be quantified in absolute terms whereby the same threshold speed is applied to all players (e.g., 5.0 m·s−1). Within rugby league, differences in tactical demand, anthropometric, and physical fitness characteristics exist between positions and players, suggesting that absolute HSR thresholds may not be appropriate because of underestimations and overestimations of HSR data. Alternatively, practitioners may individualize the threshold speed to individual players' physical qualities such as peak sprint speed, maximal aerobic speed (MAS), or the speed at which the ventilatory thresholds occur. Individualizing HSR warrants the practitioner to select a valid and practical test to quantify the HSR threshold speed. It is suggested that using peak sprint speed to quantify HSR can produce erroneous interpretation of HSR data while the practicality of specific physiological derived thresholds can be questioned. Implementing MAS to quantify HSR using a set time/distance trial may be the most appropriate approach for rugby league practitioners.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"44 1","pages":"69 - 79"},"PeriodicalIF":2.5,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41534130","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 common COD maneuver is the 180-degree turn, which is commonly assessed through the 5-0-5 COD test. Coaches and practitioners need to assess an athlete's COD performance and have access to normative data for these assessments. This review focuses on the traditional and modified 5-0-5 COD test. The 5-0-5 COD performance results have been gathered across 50 different studies and 11 different sports to create sport, sex, and level specific normative data so performance comparisons can be made, which in turn can drive programming to better effect. The reliability of both the traditional and modified 5-0-5 COD tests has been evaluated and discussed. Traditional COD ability of male athletes is better understood given there were 300 male athletes, compared with 62 female athletes. On average, males were 6.03% faster than females. Elite males were 7.78% faster than subelite and novice males, and subelite females were 3.30% faster than novice female athletes. Further research or collation of normative data is needed on female, youth, and elite cohorts to build more comprehensive databases.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"44 1","pages":"22 - 37"},"PeriodicalIF":2.5,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47986762","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}

Injuries can have detrimental effects both for the dancers and the dance company. Most injuries are in the lower limb and reported as the gradual onset of overuse. Professional dance companies have reduced injury incidence and severity through the implementation of comprehensive injury audit programs and proactive exercise prescription. Injury prevention research in dance is scarce, and there has been no intervention targeting dance injuries. This article describes the development of 11+ Dance, an injury prevention training program designed for dancers, based on current evidence and best practice on injury prevention in sports. It is a 25–30-minute neuromuscular-based training program focused on strength, balance, and jumping/landing technique, with special attention to ankle, knee, and hip alignment. The high prevalence of injuries reported in the different styles of dance suggests that implementation of an injury prevention program is both the plausible and ethical action to take for all levels of performance.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"44 1","pages":"1 - 9"},"PeriodicalIF":2.5,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44607083","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}
