Characteristics of resistance training programs targeting improvements in health outcomes in postmenopausal women: A scoping review. J Strength Cond Res XX(X): 000-000, 2025-Currently there are no evidence-based recommendations for health-promoting resistance training programs specifically for postmenopausal women. The purpose of this scoping review was to explore the characteristics of resistance training programs targeting health-related outcomes in postmenopausal women. Three databases, PubMed, Embase, and CINAHL, were searched using both controlled language and keyword searches. A total of 790 studies were screened and 69 studies met the eligibility criteria. The studies incorporated a full-body resistance training protocol (n = 52), training for specific muscle group or body part, such as back extensors (n = 13), or aquatic resistance training (n = 4). Most commonly used dose was 3 sets of 8 repetitions (n = 8) or 3 sets of 10 repetitions (n = 7). Intensity was typically described as 80% of 1 repetition maximum or as 8 repetition maximum. In the full body training programs, most common exercises were leg extensions (n = 35), leg press (n = 35), and chest press (n = 33). Most commonly measured health-related outcomes were body size and composition (n = 33) or muscular performance (n = 32). The results of this scoping review demonstrate that studies targeting to improve health-related outcomes in postmenopausal women follow the established strength training guidelines but typically do not incorporate functional exercises. Functional exercises can be important for maintaining the ability to perform common daily activities, such as carrying groceries and lifting heavy household items. Future studies should explore the feasibility and effectiveness of training protocols that combine functional exercises with resistance machine exercises.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144182434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Volume-equated high-load resisted-sprint training: determining the longitudinal effects of varying distance and repetitions on acceleration performance in rugby players. J Strength Cond Res XX(X): 000-000, 2025-Understanding how to precisely program resisted sprinting to enhance sprint phase-based adaptations is an important yet underexplored topic. This pilot study examined the impact of high-load sled-resisted sprint training when varying distance and repetitions for the same overall volume on acceleration capabilities and performance. Twenty under-19 national-level rugby players were divided into 2 groups, performing sprint sets of short or long distances over an 8-week intervention. Resistance (∼50% individual maximal velocity decrement, through load-velocity profiling) and overall volume (distance × repetitions) were equated across groups. Preintervention and postintervention testing included 10, 20, and 30 m split times, and acceleration-speed profiles to characterize maximal acceleration and speed capacities. The main effects of group, time, and their interaction were assessed using linear mixed-effects models, with the athletes as random effects, and subsequent analyses of variance. Statistically significant large mean effects were observed across for 10 m split times, maximal theoretical acceleration, and the slope of the acceleration-speed profile (omega-squared = 0.19-0.34, p < 0.044). No significant group or interaction effects were observed for any variables (p > 0.05). The findings align with existing research suggesting that high-load resisted sprinting specifically enhances acceleration capabilities. The absence of clear differences in training outcomes between the groups may be attributed to the similarity of stimuli, indicating a need for greater variation in volume distribution (e.g., increased distances per repetition) to discern effects. However, our results imply that acceleration performance improvements might be less sensitive to volume distribution variations than expected, allowing practitioners flexibility in their programming within this study's parameters.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144179988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-six physiological and 8 training load parameters were analyzed retrospectively every month throughout a 6-month summer macrocycle for 32 elite male XC and 41 BI during 7 consecutive years. During the macrocycle, XC demonstrated lower body fat (6.7 ± 1.7 vs. 7.5 ± 1.5 kg, p < 0.001) and higher muscle mass (39.7 ± 3.0 vs. 38.5 ± 3.6 kg, p < 0.001) compared with BI. In addition, XC exhibited superior aerobic capacities at ventilatory threshold (VT), including oxygen pulse, oxygen uptake, power output, stroke volume, maximum oxygen uptake (V̇o2max), and cardiac output, and maximum rate and power output for 10-second Wingate double poling (all p < 0.001). Both XC and BI showed simultaneous improvements in aerobic and anaerobic capacities, peaking during the competition period. The most consistent improvements observed throughout the macrocycle were in the upper-body power output at VT and V̇o2max (correlation with the number of training days r = 0.3-0.4, p < 0.05). Cross-country skiers engaged in significantly higher volumes of low-intensity training (LIT), total strength training, and sport-specific training (SST) compared with BI (all p < 0.001).

The effects of mixed martial arts gloves on grip strength in trained fighters. J Strength Cond Res XX(X): 000-000, 2025-Grip strength is a key component during grappling segments of a mixed martial arts (MMA) competition. Gloves are worn during MMA competitions to reduce damage to the striker and the opponent during contact. Fighters often complain that MMA gloves reduce the ability to grip an opponent effectively. However, the reported decrease in grip strength has yet to be examined. The purpose of this study was to determine the effects of mixed martial arts gloves on grip strength. Fourteen trained fighters volunteered to participate in this study. Grip strength was measured using a hand grip strength dynamometer during 2 counterbalanced trials (1 with an MMA glove and 1 without). Grip strength was measured 3 times during each trial, with 1 minute of recovery between each attempt. The highest recorded grip strength was used for each condition. Means for dependent measures (highest grip strength for both conditions) were compared using a paired sample t-test with an alpha of 0.05. Grip strength was significantly greater in the no glove condition (46.21 ± 6.14 kg) than in the glove condition (35.57 ± 6.12 kg) at p ≤ 0.001, d = -3.09. Findings from this study indicate that MMA gloves significantly decrease grip strength by 23% in relation to the no glove condition. This reduction in strength could be significant enough to result in a decrease in the ability of the fighter to control an opponent's movement. Fighters should spend more training time grappling in MMA gloves, and MMA glove redesign should be considered.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144181395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

J Strength Cond Res XX(X): 000-000, 2025-The front kick is a fundamental technique used in self-defense and hand to hand combat. This study aimed to test whether front kick performance, both with and without a 30-kg carried load, can be effectively estimated or tracked through commonly available testing procedures such as the countermovement jumps (CMJ) and one repetition maximum back squat (1RM BS). In 2 testing sessions, 21 male participants (mean age = 22.7 years, SD = 1.9) performed 1RM BS, 5 front kicks peak force (FK) without and with 30-kg carried load (FK30), and 3 CMJ without and with 30-kg carried load (CMJ30). A force plate measured the peak force (N) of the FK and FK30 and the height (cm) of the CMJ and CMJ30. Statistically significant correlations were found between CMJ and FK (r = 0.55 [0.225-1], p = 0.005) and CMJ and 1RM BS (r = 0.54 [0.219-1, p = 0.005]). Carried load reduced both CMJ height by 61% (d = 3.35 [2.543-∞], p < 0.001) and FK peak force by 23% (d = 1.33 [0.828-∞], p < 0.001), compared without load condition. A regression model using 1RM BS and CMJ explained 31.5% of FK variance, with only the height of CMJ being statistically significantly associated, β = 0.626, p = 0.015. The study demonstrates that although there is a relationship between explosive power and maximum strengths, FK is more related to CMJ height than 1RM BS. From a practical standpoint, the study suggests that explosive power shows a better association with the FK than the maximal strength. Thus, training programs focused on lower limb explosive power could allow athletes and military personnel to achieve higher FK. Combat sports trainers and hand-to-hand combat instructors may thus consider accordingly updating their training schemes, emphasizing plyometrics and other explosive training methods for enhancing the peak force of kicks.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144180245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tethered force and upper-body strength measures were expressed as absolute values and relative to surfers' bodyweight. Lasso regression and machine learning analyses determined the tethered force and upper-body strength and ROM variables that indicated faster 5-, 10-, and 15-m sprint-paddling split times (p < 0.05). Analyses revealed that relative measures were superior in identifying variables significantly contributing to sprint-paddling split times and were better at predicting these split times. Greater relative mean tethered force, isometric shoulder strength and ROM ER:IR ratios, as well as relative and absolute 1RM pull-up significantly contributed to faster split times for all surfers.

Ten healthy young adults randomly completed both of 2 trials of ST exercises, for 30 (T30) or 45 (T45) seconds. The training load was monitored using a mobile gas analyzer, heart rate monitors, and blood lactate measurements. The total energy expenditure (TEE) (classified as the sum of oxidative [OES], glycolytic [GC], and excess postexercise energy cost [EPOC]) was estimated using the V̇o2 consumption (at rest, during exercise, and postexercise) and blood lactate (La) concentration (at rest and postexercise). The level of significance was set at p ≤ 0.05. All exercises were associated with a low-to-moderate physiological strain (rate of perceived exertion: 7.3-12.3; % of maximal heart rate: 52.3-61.7%; METs: 2.6-3.7; La: 2.2-3.9 mM; EPOC duration: 5.7-7.8 minutes), with the OS and the SLS associated with the greatest physiological/metabolic load in both trials. T45 induced a greater heart rate (53.7-61.7 %HRmax), with SLS and OS inducing the highest values. Minimal differences were noted between T30 and T45 for TEE, MET, and La values for most. EPOC had a greater contribution to TEE compared with OES and GC. Low-to moderate physiological effort during ST results in a TEE of 16.6-24.7 and 20.1-30 kcal·min-1 when performed for 30 and 45 seconds, respectively.
