Muscle imbalance due to reduced muscular endurance is a significant risk factor. Thus, for the lower limb, muscle imbalance is one of the most common causes of traumatic injury. A number of studies on isoinertial technology have demonstrated that it allows the development of forces similar to or greater than those generated in the same exercise but performed with traditional weights. Our research aimed to analyze the morpho-functional changes at the muscle level using ultrasound, and the evolution of muscle power output express of maximal muscle strength at the level of the knee extensors, specifically the rectus femoris muscle, following an isoinertial training program. The study included 11 female soccer-practicing sportswomen with average age (15.18 ± 1.08). The assessment included an ultrasound assessment of the rectus femoris muscle, before and after isoiniertial training (post acute moment); a muscle force assessment using dynamometry; and an evaluation of isoinertial parameters as concentric and excentric power, in terms of coefficients that represent report between the left and right sides. The isoinertial protocols training included three weekly sessions of isoinertial exercises. The results show an increase in the values of the ultrasound dimensions, approximately at the same level for both measured dimensions, which is significant for demonstrating the existence of an increase in muscle volume. An important progress is observed in the mean maximum strength and maximum force, but especially in the duration of maintenance of the maximum loading force. There is no statistically significant symmetry at the level of the rectus femoris muscle for concentric power and no statistically significant symmetry tendency for eccentric power, although there is a favorable evolution in terms of values.

This study focuses on the experiences of female Paralympic athletes in Brazil through the lens of feminist disability studies. It is a qualitative study, grounded in the voices of disabled women, positioning them as the foundation of knowledge within a post-structuralist epistemological framework. The research involved in-depth interviews with four Brazilian Female Paralympians, conducted using a predefined interview guide, and the data were analyzed using thematic content analysis. The athletes were between 25 and 34 years of age and had experience competing in international competitions. From their narratives, two distinct yet interconnected categories emerge: (1) Being a disabled woman and (2) Like sportswomen. Disabled women have shown that they navigate an ableist and sexist society as disabled women within the context of sport; at the same time, they embody an empowered and inspirational identity as sportswomen. By exploring these perspectives, this study highlights the need to challenge and redefine societal perceptions and expectations surrounding disability. It provides insights into the experiences and agency of female Paralympic athletes. Full article

Background/Objectives: Implementing and optimizing pelvic floor muscle (PFM) training programs is crucial for reducing the risk of dysfunctions, improving athletic performance, and enhancing quality of life for athletes. The aim of this study was to assess PFM activation in female athletes during postural challenges. Methods: An observational and descriptive study was conducted with twenty-five female rugby players. Surface electromyography was used to evaluate the PFMs in five different body positions under stable and unstable conditions. Results: The peak amplitude of the PFMs at baseline differed according to the physical demand of each position (p < 0.001). The lowest percentage activation was in the supine position (16.23%), while the highest recruitment was observed during the parallel squat (40.69%). The percentage of maximum voluntary contraction also differed according to each position (p = 0.001). The values were similar in supine position, side plank (104%), and standing position, being significantly lower (p < 0.05) than those reached during the off-knees quadruped hold (121.58%), full plank (121.97%), and parallel squat (151.40%); however, the values were comparable between stable and unstable positions (p = 1.000). Conclusions: Positions that challenge gravity and pelvic biomechanics, such as the squat, plank, and quadruped, facilitate greater activation of the PFMs. Contrary to previous recommendations, these exercises do not appear to have significant negative effects; therefore, consideration should be given to the implementation of these exercises for the management of pelvic floor dysfunction and as part of comprehensive exercise programs designed to improve overall core and pelvic floor function.

This study explores the representation of female athletes cast in a South Korean reality show titled Sporty Sisters (Korean title: Nonun Unni). Though there have been attempts to understand the media representation of female athletes from diverse media landscapes, the analysis of Asian female athletes is limited. Such interpretations have been discussed through geopolitical relations or nationalistic representations, which lack in-depth understanding and exploration of Asian athletes. Therefore, this paper expands the narrative by analyzing the first season (54 episodes) of Sporty Sisters. It is observed that professional athletes who transition to the entertainment industry are identified as “spor-tainers” and implicitly follow norms and rules applied to public figures. In this reality show, female athletes express their opinions on marriage, menstruation, pregnancy, and domestic roles while displaying characteristics of a girl crush, manifesting a variety of the female attributes of sportswomen. Despite the social expectations to fulfill their roles as sports celebrities and Korean women, Sporty Sisters is an outlet for female athletes to an extent to freely expose and describe their experiences as athletes and individuals.

(1) Background: Pelvic-floor-muscle (PFM) activation acts synergistically with multiple muscles while performing functional actions in humans. The purpose of this study was to characterize the activity of the PFMs and gluteus medius (GM) while walking and running in physically active nulliparous females. (2) Methods: The peak and average amplitude of maximal voluntary contractions (MVCs) during 60 s of walking (5 and 7 km/h) and running (9 and 11 km/h) were measured with electromyography of the GM and PFMs in 10 healthy female runners. (3) Results: The activation of both muscles increased (p < 0.001) while walking and running. The MVC of the GM was reached when walking and tripled when running, while the PFMs were activated at half their MVC when running. The global ratio of the GM (75.3%) was predominant over that of the PFMs (24.6%) while static and walking. The ratio reached 9/1 (GM/PFM) while running. (4) Conclusion: The GM and PFMs were active while walking and running. The GM’s MVC tripled at high speeds, while the PFMs reached only half of their maximum contraction. Full article

Background: Exercise can stress the pelvic floor muscles (PFMs). This study sought to assess the strength of the PFMs according to the level of physical exercise. Methods: An analytical observational study was carried out using digital palpation and dynamometry measurements to assess PF strength. Healthy nulliparous women were stratified according to physical exercise (physically active and sedentary) and level of physical exercise (elite, amateur, and sedentary). Results: Fifty-four women were analyzed, with a mean age of 25.64 (5.33) years and a BMI of 21.41 (2.96) kg/m². Differences in the passive force and strength were observed between both groups of women (p < 0.05), and the strength was around two times higher in physically active women (p < 0.05). The strength was similar between elite female athletes and sedentary women (p > 0.05), but statistical differences were found with amateurs (p < 0.05). The PFM strength (p = 0.019) of elite female athletes (0.34 N) was almost half that of amateurs (0.63 N) and twice as strong as that of sedentary women (0.20 N). However, these differences were not significant using digital palpation (p = 0.398). Conclusions: Women who exercise generally have greater PFM strength than women who do not exercise. Physical exercise could strengthen the PFM; however, the high intensity demanded by high-level sports does not seem to proportionally increase the strength of the PFMs. Full article

This paper will show that sporting institutions that police the boundaries of women’s sports do so to keep sportswomen constrained in ways that men’s sports and male athletes are not. This paper explores three methods that sporting establishments have used to police and constrain women’s sports and sportswomen: the exclusion of women and the creation of different rules for men’s and women’s sports, the policing of international sporting administrations of which women can compete in women’s sports by invoking the specter of “gender fraud”, and the exclusion of trans women from sports by relying on conservative Christian notions of a gender binary motivated by a similar strain of homophobia that animated previous efforts to prevent the legalization of same-sex marriage. Taken together, these three threads reveal that gender policing in women’s sports is not and has never been about “fairness” but about preserving heteropatriarchal systems of power that position women as weak and inherently less athletic than men.

In order to maximize sports performance of team sportswomen, knowledge of the player’s characteristics in terms of different aspects and at different times of the season is needed. While the anthropometric and physical characteristics of men’s sports teams have been extensively studied, research on women’s basketball and volleyball is scarce. (1) Purpose: This study aims to contribute data about the anthropometric and physical characteristics of female basketball and volleyball players from elite women’s teams (age: 24.3 ± 2.7 years; playing experience: 14.825 ± 2.8 years) (n = 23) with a two-fold objective: (1) to describe and compare the anthropometric characteristics of these two disciplines; and (2) to identify possible differences in various parameters of sports performance depending on the discipline. (2) Methods: The anthropometric profile includes the measurements recommended by the International Society for the Advancement of Kinanthropometry; the performance tests described aerobic and anaerobic power exercises. (3) Results: The overall somatotype of the players was moderate mesomorphic and low endomorphic (5.107–3.046–1.883). Statistical differences were found between the improvement of the physical performance level of female basketball players (77%) and female volleyball players (10%) from the first to the last measurement, with better results in most of the performance tests (p < 0.05). The sum of skinfolds was higher in female basketball players (p > 0.05). The percentage of fat-free mass correlated with improvements in lower body strength. (4) Conclusion: Lean body mass is an important predictor of exercise performance intensity. Excess fat mass is detrimental to the development of strength and endurance. Full article

Paralympic participants represent a special subset of athletes. Although sudden cardiac death in this group is a rare event, it should be underlined that, in particular, Paralympians with movement restrictions have a higher prevalence of coronary heart disease. Numerous reports have focused on comparing athletes with spinal cord injury (SCI) and the ones with non-spinal cord injury—NSCI. The first group is more prone to develop arrhythmias, arterial hypertension, hyperlipidaemia including atrial fibrillation and atrial flutter, and this group potentially may have a higher risk of cardiovascular mortality. In ECGs of the disabled athletes with SCI, we more often find changes typically established as consequences of exercise training, such as T-wave inversions. The potential differences in the cardiovascular status of disabled athletes may depend not only on the class of impairment, but also on the discipline of sport and environmental conditions, which makes the analysis relatively complex. The paper analyses up-to-date articles discussing the cardiovascular problems in disabled athletes, pointing to scarce data in several fields of interest. Previous studies on the frequency of abnormalities of the cardiovascular system in Paralympic athletes highlighted the need to intensify preventive cardiology care for this group of athletes, and some activities could be proposed for sportsmen and sportswomen in this group, including more frequent screening ECG, application of 24 h ECG Holter monitoring, echocardiography and cardiological care. Due to the relatively few data available and existing discrepancies in this area, further research is necessary. Full article

Eating disorders are characterized by abnormal, unhealthy eating habits, and disordered body image. In severe cases, it can cause serious health consequences, including cardiac problems, osteoporosis, infertility, or missing menstrual periods. In women competitively training sports, the main cause for disordered eating behaviours are factors associated with dissatisfaction with their appearance and body image and a need to reduce body weight. Factors related to dissatisfaction with one’s own appearance and body image, a need to reduce body weight, a negative perception of themselves and their bodies, the pressure in sports circles, and stress are predictors for eating disorders. The aim of the study was to compare eating behaviours, body satisfaction, and taking various actions related to body mass reduction among women training competitively in volleyball, athletics, gymnastics, and young women not participating in sports. Material and methods: The study covered a group of girls and young women from the Silesian, Poland, who represented three sports disciplines (volleyball, athletics, and gymnastics), of which 30 girls were used as a control group (B). The study was conducted using a study questionnaire. Results: The study participants ate regularly and consumed all food groups during a week. The majority of girls from A1 (83.33%), A3 (53.33%), and B (80%) groups expressed their dissatisfaction with their body weight. In the group of gymnasts, a positive correlation was noted between the need to reduce body weight and regular eating (r = 0.449; p = 0.013). In the group of volleyball players, it was demonstrated that the higher the competitive experience and the greater the training load, the more regular their eating was (r = 0.475; p = 0.009). Conclusions: The importance of a diagnosis of early signs of eating disorders in girls and women as a basic component contributing to FAT development implies that further studies in this area, as well as education of the entire sports circle are necessary.

Increasing numbers of females are participating in elite sports, with a record number having competed at the Tokyo Olympic Games. Importantly, the ages of peak performance and fertility are very likely to coincide; as such, it is inevitable that pregnancy will occur during training and competition. Whilst there is considerable evidence to promote regular exercise in pregnancy, with benefits including a reduction in hypertensive disorders, gestational diabetes, and reduced rates of post-natal depression, few studies have been conducted which include elite athletes. Indeed, there are concerns that high-intensity exercise may lead to increased rates of miscarriage and preterm labour, amongst other pregnancy-related complications. There is minimal guidance on the obstetric management of athletes, and consequently, healthcare professionals frequently adopt a very conservative approach to managing such people. This narrative review summarises the evidence on the antenatal, intrapartum, and postpartum outcomes in elite athletes and provides recommendations for healthcare providers, demonstrating that generally, pregnant athletes can continue their training, with a few notable exceptions. It also summarises the physiological changes that occur in pregnancy and reviews the literature base regarding how these changes may impact performance, with benefits arising from pregnancy-associated cardiovascular adaptations at earlier gestations but later changes causing an increased risk of injury and fatigue.

The concept of emotional intelligence is related to the recognition of our own emotions, their regulation and our state of mind. Additionally, it is increasingly relevant in society in general, and in the field of sport in particular. The aim of this paper is to analyze the relationship between emotional intelligence and the theory of self-determination, specifically interpersonal relationships. For this purpose, sex was taken as a mediating variable, and a structural equation model was estimated through mediation. The sample was made up of a total of 165 active sportsmen and sportswomen who are studying undergraduate and master’s degree courses related to physical activity and sport sciences. The results show that gender acts as a mediating variable between emotional intelligence and relationships with others, becoming a mediating variable of two previously unrelated variables. The implications of these results lead us to study both emotional intelligence and its importance in the field of sport, as well as the fact of paying attention to the differences that may exist in this case depending on gender.

Sports are yielding a wealth of benefits for cardiovascular fitness, for psychological resilience, and for cognition. The amount of practice, and the type of practiced sports, are of importance to obtain these benefits and avoid any side effects. This is especially important in the context of contact sports. Contact sports are not only known to be a major source of injuries of the musculoskeletal apparatus, they are also significantly related to concussion and sub-concussion. Sub-concussive head impacts accumulate throughout the active sports career, and thus can cause measurable deficits and changes to brain health. Emerging research in the area of cumulative sub-concussions in contact sports has revealed several associated markers of brain injury. For example, recent studies discovered that repeated headers in soccer not only cause measurable signs of cognitive impairment but are also related to a prolonged cortical silent period in transcranial magnetic stimulation measurements. Other cognitive and neuroimaging biomarkers are also pointing to adverse effects of heading. A range of fluid biomarkers completes the picture of cumulating effects of sub-concussive impacts. Those accumulating effects can cause significant cognitive impairment later in life of active contact sportswomen and men. The aim of this review is to highlight the current scientific evidence on the effects of repeated sub-concussive head impacts on contact sports athletes’ brains, identify the areas in need of further investigation, highlight the potential of advanced neuroscientific methods, and comment on the steps governing bodies have made to address this issue. We conclude that there are indeed neural and biofluid markers that can help better understand the effects of repeated sub-concussive head impacts and that some aspects of contact sports should be redefined, especially in situations where sub-concussive impacts and concussions can be minimized.

We studied 6368 people (4544 women and 1824 men; aged 18–74 years). The research goal was to determine whether the Cognitive Reflection Test score (logical thinking compared with intuitive thinking) depends—and in what way it depends—on the healthy lifestyle components and emotional health-related components as well as age (18–74 years) and gender. We established that analytical vs. intuitive thinking depended on components of a healthy lifestyle, physical activity, sleep, eating habits, smoking and alcohol consumption, specificity of sporting activity, body mass index, and emotional health-related components (stress, depression, impulsivity, subjective health, emotional intelligence), as well as age and gender. We found that logical thinking was not associated with sleep, moderate-to-vigorous PA, impulsivity, subjective health, and components of a healthy lifestyle. However, logical thinking decreases with age, gender (higher in men than in women), BMI (decreases in both genders over the second degree of obesity), depression (the more severe depression in women, the worse their logical thinking), sedentary behavior (people who sat for longer periods had more difficulty solving problems), and in professional sportswomen (logical thinking is worse in professional sportswomen than in sedentary women, amateur sportswomen, or women who use gyms). Finally, we determined inverse correlations between logical thinking, emotional intelligence, and stress. Full article

Several aspects of systemic alterations caused by the SARS-CoV-2 virus and the resultant COVID-19 disease have been currently explored in the general population. However, very little is known about these particular aspects in sportsmen and sportswomen. We believe that the most important element to take into account is the neuromuscular aspect, due to the implications that this system entails in motion execution and coordination. In this context, deficient neuromuscular control when performing dynamic actions can be an important risk factor for injury. Therefore, data in this review refer mainly to problems derived in the short term from athletes who have suffered this pathology, taking into account that COVID-19 is a very new disease and the presented data are still not conclusive. The review addresses two key aspects: performance alteration and the return to regular professional physical activity. COVID-19 causes metabolic-respiratory, muscular, cardiac, and neurological alterations that are accompanied by a situation of stress. All of these have a clear influence on performance but at the same time in the strategy of returning to optimal conditions to train and compete again after infection. From the clinical evidence, the resumption of physical training and sports activity should be carried out progressively, both in terms of time and intensity. Full article
