We argue that physical strength is best understood, in philosophical terms, as the general agentive ability to exercise difficult physical effort. We develop this claim by examining the historically developed and paradigmatic test of overall strength: the sport of Strongman/woman. We identify the understanding of strength embedded in this sport and show how contemporary philosophical accounts of agentive ability capture its main features. Finally, we argue that Strongman/woman competitions are already well designed for assessing strength. By balancing the trade-offs involved in quantitative measurement, they provide a robust interdisciplinary tool for strength assessment.

Post-competition refeeding in physique athletes is poorly understood. We aimed to characterize physiological and psychological changes in natural physique athletes across contest preparation and a 12-week recovery period, and to explore the influence of post-competition refeeding strategies. Nineteen natural physique athletes (8 male, 11 female) were assessed at baseline (~21 weeks pre-competition; T0), 1-2 weeks pre-final competition (Tpre), and 2, 6, and 12 weeks post-competition (T2, T3, T4). Measures included body composition (DXA), resting metabolic rate (RMR), thyroid hormones (FSH, FT3, FT4), absolute strength (IMTP peak force), and psychometric questionnaires (POMS, ASSQ, EDE-QS). Body weight decreased from T0 to Tpre (-7.1 kg [-8.3, -5.9]), driven primarily by FM loss (-5.8 [-6.8, -4.8]), with modest FFM loss (-1.7 [-2.6, -0.9]). Both FM and FFM rebounded predominantly within the first 6 weeks post-competition (Tpre→T3: +3.4 [2.3, 4.4] and +2.7 [1.8, 3.6], respectively). By T4, FM was not clearly different from T0 (-0.8 [-1.8, 0.3], while FFM exceeded T0 (+1.6 [0.7, 2.5]). RMR·FFM^-1 showed a small, uncertain reduction from T0 to Tpre (-0.9 kcal·kgFFM^-1·day^-1 [-2.7, 0.9]), followed by increases from Tpre to T4 (+2.4 [0.7, 4.1]). Thyroid hormones decreased from T0 to Tpre (FT3: -1.4 [-1.8, -0.9], FT4: -1.4 [-2.6, -0.2]) and returned within reference ranges by T4. Strength was broadly maintained, while mood and sleep worsened from T0 to Tpre, and improved by T4. Eating-disorder symptom severity was highest during preparation and declined across the recovery period. In exploratory Bayesian modelling, larger post-competition increases in energy intake were associated with greater recovery of adjusted RMR. Contest preparation was accompanied by fat loss, thyroid hormone suppression, and modest reductions in RMR, with recovery characterized by early increases in RMR and tissue restoration following competition. Larger post-competition increases in energy intake were associated with faster recovery of adjusted RMR, although FM regain occurred concurrently. Post-competition recovery should be treated as an active, structured phase, with refeeding individualized to athlete goals and psychological readiness and guided by multi-system monitoring rather than RMR alone. Athletes and coaches should plan ahead for this phase, with structured increases in food intake, realistic expectations around fat gain, and avoidance of unnecessarily prolonged restriction that may delay physiological recovery.

Rapid weight loss is common in weight category sports, and large magnitudes of it can affect performance. This study explored relationships between changes in the Short Recovery and Stress Scale (SRSS) items and the magnitude of rapid weight loss in elite powerlifters competing at the World Championships. A total of 53 powerlifters (27 males, 26 females) who competed in either the 2019 or 2022 International Powerlifting Federation World Championships participated. At 7, 2, and 0 days out from competition, the participants completed the SRSS and recorded their body mass. Cumulative link mixed models were used to explore the relationship between SRSS score and proximity to competition, competitive caliber (good lift points [GLP]), sex, and magnitude of relative weight change. On average, the participants lost -2.5% (1.83 kg) of body mass from day 7 to day 0. The results suggest that (a) elite powerlifters can decrease subjective stress and promote recovery leading into competition, (b) powerlifters with higher GLP at competition are more likely to report better recovery and negative emotional state scores, (c) higher relative magnitude of weight loss is associated with worse subjective stress and recovery scores, and (d) female powerlifters experience worse negative emotional state responses with higher relative weight loss. These findings highlight that the magnitude of rapid weight loss can affect subjective stress and recovery and provide data to inform future hypothesis testing.

Bodybuilding and physique sports are often clouded by myths and misconceptions about training, nutrition, and supplements. This article examines some of the myths in the fitness community, including periodization for muscle growth, the belief that training to failure is required, and the idea that cardiovascular training impairs hypertrophy. In addition, this article covers misconceptions about nutritional strategies, such as the need for restrictive diets, the effectiveness of fasted cardiovascular training, and the importance of meal timing. The fear that women will become bulky from resistance training and the misclassification of creatine as a steroid are also addressed. Drawing on current scientific evidence, we demonstrate that progressive overload, intensity management, and flexible dieting are more effective and sustainable than other methods. Cardiovascular training, when properly integrated, does not hinder muscle growth, and women benefit from resistance training without developing excessive muscle mass. Creatine supplementation is validated as a safe and effective ergogenic aid and is distinct from anabolic steroids. By debunking and contextualizing these myths, this article provides bodybuilders and physique athletes with evidence-based training and nutrition strategies to optimize performance, support long-term health, and maximize results safely and efficiently.

Short Term Body Mass Manipulation (SBM) is frequently used in powerlifting by athletes to qualify for lower weight classes and improve relative competitiveness. The three primary physiological pathways that SBM leverages are gastrointestinal content reduction, glycogen storage and body water manipulation, in addition to post-weigh-in refueling. Despite its high prevalence among athletes competing in the International Powerlifting Federation (IPF), the scientific literature on SBM remains limited, and sport-specific guidelines are currently lacking. This narrative review summarizes the current evidence on SBM in powerlifting, with a focus on physiological mechanisms, practical implementation, and associated risks. The specific demands of IPF competition, consisting of maximal strength performance after only a two-hour window between weigh-in and competition, necessitate uniquely tailored SBM strategies. SBM should not be regarded as a standard preparation method. Instead, it should be seen as a targeted intervention to be applied with caution and strategic intent. The decision to implement SBM must be based on individual assessment, physiological plausibility, and a well-considered cost-benefit rationale. Ensuring effective rehydration and refueling between weigh-in and competition is critical to support both safety and performance. This review provides sport specific, evidence-based recommendations to assist practitioners in applying SBM responsibly within the context of powerlifting.

The inconsistency and disparities in existing functional training definitions have led to confusion when explaining the concept and its potential. The wide range of interpretations suggests that any training approach could be deemed functional, thereby diminishing the significance of the term and significantly limiting its understanding and application. Thus, this paper aimed to develop the first consensual definition of functional training using an international e-Delphi method. From a panel of 31 experts initially selected, 13 participated in the consensus. The panel presented the following definition: 'Functional training is a physical interventional approach that contributes to the enhancement of human performance, according to individual goals, in sports, daily life, rehabilitation, or fitness, and takes into consideration the specificity of the task and the unique responsiveness of each individual'. However, redundancy of the functional training definition emerged as a relevant consideration for this conceptual and methodological advancement, and a proposal to avoid the distinction between functional training and the general concept of training was presented (i.e., no real use of functional training as a concept). It was proposed that a training program or regimen could be analyzed based on a continuum of functionality, which could support further developments in this topic.

Both resistance training (RT) and long‐duration, high‐intensity stretching induce muscular adaptations; however, it is unknown whether the modalities are complementary or redundant, particularly in well‐trained individuals. A case‐study was conducted on a competitive bodybuilder implementing long‐duration, high‐intensity stretching of the plantar flexors (60 min 6x/week for 12 weeks) in conjunction with their habitual RT. Ultrasound muscle architecture (muscle thickness [MT], fascicle length [FL], and pennation angle [PA]) measurements were collected at multiple sites at four weekly baseline sessions, six (mid) and 12 (post1) weeks following the commencement of the intervention, and a week after the intervention (post2) while isometric strength and range of motion (RoM) were obtained once at baseline, mid, post1, and post2. 2SD band plots were constructed to determine meaningful changes in MT, FL, and PA from the four baseline measures while percentage and absolute change across each timepoint were calculated for all variables. From baseline to post 1, RoM, strength, and MT increased 25.9%, 11.4%, and 7.4%–23.4%, respectively, while four MT and two PA sites exceeded the threshold for meaningful change. The combined stretching and RT protocols resulted in flexibility, strength, and MT adaptations; however, findings should be generalized with caution given the case‐study nature of our investigation.

While body image dissatisfaction (BID) and eating disorders (EDs) are relatively common in athletes (ranging from 11% to 67% of athletes, depending on the sport) [1], they are also prevalent in weight-class restricted sports (a common format in strength sports), and among physique athletes [2]. These athletes manipulate their nutrition to reach aesthetic or body weight standards and, in that process, may undergo prolonged periods of low energy availability. Low energy availability, defined as consuming insufficient energy for one's lean mass and exercise activity, can lead to Relative Energy Deficiency in sport (REDs), a syndrome that can impact menstrual cycle (MC) symptoms (and many other aspects of physiology and psychology) [3]. There has not been an investigation into the relationships between these resistance-trained (RT) athletes' nutritional habits, MC-related symptoms, BIDs, and EDs. A survey was implemented to explore the dieting habits, MC characteristics, BID, and EDs in RT females. 64.6% (n = 469) of participants reported tracking calories, with a slightly higher percentage of competitive athletes tracking calories 71.8% (n = 181) than recreational-level athletes. Competitive athletes were significantly more likely to track calories than recreational-level athletes (p = 0.003). When asked what the primary purpose of calorie restriction was, most participants selected weight loss for aesthetic purposes 58.8% (n = 356). Competitive athletes were less likely to select weight loss for aesthetic purposes 35.7% (n = 77), but weight loss for the purpose of a weight class-based sport was higher at 43.5% (n = 94). There were no significant associations between BID and MC characteristics or most MC symptoms and limited associations between EDs and MC characteristics and symptoms. RT athletes exhibited a higher prevalence of calorie tracking than the general population. Competitive RT athletes were less likely to calorie restrict for aesthetic purposes than non-athletes, but more likely to calorie restrict for the purpose of weight-class-based sports. There were limited significant associations between BID and MC characteristics or MC symptoms, as well as between EDs and MC characteristics. However, there was a significant association between amenorrhea and EDs, which aligns with previous research in this area. Both BID and EDs were significantly associated with MC-based mental health effects; this is likely due to the interconnected nature of mental health concerns, such as EDs with depression and anxiety.

Homer, KA, Cross, MR, and Helms, ER. A survey of resistance training practices among physique competitors during peak week. J Strength Cond Res 38(10): 1745–1752, 2024—Physique athletes are ranked by their on-stage presentation of muscle size, proportionality, and leanness. To acutely maximize muscle size, competitors manipulate resistance training (RT) variables in the days before the contest, commonly referred to as peak week (PW). Resistance training manipulations during PW may act synergistically with nutrition strategies such as carbohydrate loading. However, because little information exists on changes made to RT during PW, the purpose of this research was to determine the current practices of physique athletes and whether competitor characteristics were predictive of the RT variables manipulated. A total of 104 responses to the RT section of a survey on PW nutrition and training were analyzed through a series of multiple logistic regression models to examine the relationship between RT manipulations and competitor characteristics. Furthermore, to determine the magnitude of differences between PW and the week before PW (WBPW) for these variables, a McNemar-Bowker test, paired t-tests, and Wilcoxon signed-rank tests were conducted for nominal, continuous, and discrete outcomes, respectively. For all statistical analyses, p <0.05 was deemed significant. Competitors generally adjusted RT in a variety of ways, where proximity-to-failure was the most frequently manipulated and training frequency was the least; however, no competitor characteristic predicted any of the RT variables manipulated. Within those who manipulated RT variables during PW, frequency, volume, and intensity decreased while repetition ranges of compound exercises increased, empirically confirming that competitors seek to reduce training stress during PW. Such findings can be incorporated in future experimental designs examining the efficacy of peaking strategies to enhance the generalizability of results.

Physique athletes are subjectively judged on their on-stage esthetic per their competition division criteria. To succeed, competitors look to acutely enhance their appearance by manipulating nutritional variables in the days leading up to competition, commonly referred to as peak week (PW). Despite their documented wide adoption, PW strategies lack experimental evidence. Further, the relationship between the specific strategies and the characteristics of the competitors who implement them are unknown. The aim of this research was to examine the effect of competitor characteristics on the specific nutritional peaking strategies implemented, the length of these strategies, and the range of daily carbohydrate (CHO) intakes during these strategies. A 58-item survey was developed to gather information on peak week nutrition and training practices of physique athletes. A total of 160 respondents above the age of 18 who had competed in the last 5 years completed the nutrition section. The topics analyzed for this paper included competitor demographics, peaking strategies utilized, and PW CHO intakes. Competitor demographics are presented with the use of descriptive statistics. Associations between competitor demographics and peaking strategies implemented, peaking strategy length, and daily CHO intake ranges were assessed using multiple logistic regression, multiple ordinal logistic regression, and linear mixed models, respectively. From the sampled population, ages 24-39 years (71.2%), male (68.8%), natural (65%), and amateur (90%) were the most common characteristics from their respective categories, while mean competition preparation length was 20.35 ± 8.03 weeks (Males: 19.77 ± 7.56 weeks, Females: 21.62 ± 8.93 weeks), competition preparation body mass loss was 11.5 ± 5.56 kg (M: 12.7 ± 5.76 kg, F: 7.16 ± 3.99 kg), and competition body mass was 72.09 ± 15.74 kg (M: 80.15 ± 11.33 kg, F: 54.34 ± 7.16 kg). For males, the highest and lowest daily CHO intake during PW were 489.63 ± 224.03 g (6.22 ± 2.93 g/kg body mass) and 148.64 ± 152.01 g (1.94 ± 2.17 g/kg), respectively, while for females these values were 266.73 ± 131.23 g (5.06 ± 2.67 g/kg) and 94.42 ± 80.72 g (1.81 ± 1.57 g/kg), respectively. CHO back loading (45%) and water loading (40.6%) were the most popular peaking strategies, while the most prevalent peaking strategy length was 7 days (27.2%). None of the competitor characteristics predicted the use of CHO-based peaking strategies nor peaking strategy length. For non-CHO-based strategies, drug-enhanced competitors were more likely to restrict water than non-drug enhanced, while males and professional competitors had greater odds of loading sodium than females and amateurs, respectively. Finally, when comparing the disparity in highest and lowest CHO intakes during peak week, sex was the only significant factor. The results of this survey provide further information on the nutritional peaking strategies implemented by competitors. Certain characteristics were identified as predictors of sodium loading and water restriction, and the range of daily PW CHO intake. Contrastingly, no associations were found for CHO-based peaking strategies or peaking strategy length. While our analyses may be underpowered, and thus results should be interpreted with caution, it appears the nutritional peaking strategies implemented by physique competitors are seemingly complex and highly individual.
