Is the Elite Female Athlete's Pelvic Floor Stronger?

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.

Musculoskeletal pains among amateur and professional athletes of five disciplines in Senegal: a preliminary study.

BACKGROUND: Musculoskeletal pains (MSPs) in sport are cause of poor performances and loss of competition in athletes. The present study aimed at determining the prevalence of MSPs with regard to sport disciplines and athletic status. METHODS: A cross-sectional study was conducted among 320 Senegalese professional and amateur athletes practicing football, basketball, rugby, tennis, athletics, and wrestling. Rates of MSPs in the past year (MSPs-12) and week (MSPs-7d) were assessed using standard questionnaires. RESULTS: Overall proportions of MSPs-12 and MSPs-7d were 70 and 74.2%, respectively. MSPs-12 were more frequently reported on shoulders (40.6%), neck (37.1%) and hips/thigh (34.4%), while MSPs-7d were predominant on hips/thigh (29.5%), shoulders (25.7%), and upper back (17.2%). Proportions of MSPs-12 and MSPs-7d varied significantly by sport disciplines, with highest values among basketball players. Again, highest MSPs-12 proportions on shoulders (29.7%, P = 0.02), wrists/hands (34.6%, P = 0.001), (40.2%, P = 0.0002), and knees (38.8%, P = 0.002) were seen among basketball players. High proportions of MSPs-7d were seen on shoulders (29.6%, P = 0.04) for tennis players, wrists/hands (29.4%, P = 0.03) for basketball and football players, and hips/thigh (38.8%, P < 0.00001) for basketball players. Football players had reduced risk of MSPs-12 by 75% on lower back (OR = 0.25; 95% CI. 0.10-0.63; P = 0.003) and by 72% on knees (OR = 0.28; 95% CI. 0.08-0. 95; P = 0.04). In contrast, tennis players were more at risk of MSPs-12 on shoulders (OR = 3.14; 95% CI. 1.14-8.68; P = 0.02), wrists/hands (OR = 5.18; 95% CI.1.40-11.13; P = 0.01), and hips/thigh (OR = 2.90; 95% CI. 1.1-8.38; P = 0.04). Professionals were protected from MSPs-12 on neck pain with a significant reduction of risk by 61% (OR = 0.39, 95% CI. 0.21-0.75, P = 0.03). CONCLUSION: MSPs are a reality among athletes and their risk is modulated by sport disciplines, athletic status and gender.

RESUMO A melhoria da técnica desportiva baseia-se na premissa de comparar os valores do movimento motor, que deve ser caracterizada a fim de corrigir erros detectados como parte do processo de gestão do treino desportivo. A tónica é colocada no desporto eminentemente técnico, como é o caso do treino de musculação. Neste sentido, o objectivo desta investigação era analisar a técnica de meio agachamento em musculturistas profissionais e iniciantes como um método empírico (medição específica do desporto). A investigação é descritiva-explicativa da ordem correlativa. Seis variáveis de interesse estão correlacionadas (X1: ângulo da articulação do ombro; X2: ângulo da articulação da anca; X3: velocidade máxima alcançada; X4: aceleração máxima alcançada; X5: centro de gravidade em X; X6: centro de gravidade em Y). Os meios estabelecem diferenças entre grupos independentes, tanto na variável X1 (Grupo 1: ≈66°; grupo 2: ≈70°; p=0,247), a X2 (grupo 1: ≈73°; grupo 2: ≈86°; p=0,002), a X3 (grupo 1: ≈1. 03m/s; grupo 2: ≈1.36m/s; p=0.017), o X4 (grupo 1: ≈2.93m/s2; grupo 2: ≈4.78m/s2; p=0.011), o X5 (grupo 1: ≈0.43m; grupo 2: ≈0.65m; p=0.000), e o X6 (grupo 1: ≈0.61m; grupo 2: ≈0.83m; p=0.000). O grupo 1 tem uma técnica mais eficaz, enquanto os iniciantes têm uma eficiência de movimento biomecânico mais baixa devido à sua inexperiência, eles mostram menos eficiência no movimento biomecânico. Dada a sua inexperiência, são mostrados valores elevados em velocidade e aceleração, e são incluídos ângulos de movimento como o ângulo da anca.

ABSTRACT The improvement of the sports technique is premised on comparing the values of the motor movement, this must be characterized to correct errors detected as part of the sports training management process. Emphasis is placed on highly technical sports, such as bodybuilding training. In this sense, the present research aimed to analyze the half-squat technique in professional and amateur bodybuilders as an empirical method (sport-specific measurement). The research is descriptive-explanatory of correlational order. Six variables of interest are correlated (X1: shoulder joint angle; X2: hip joint angle; X3: maximum speed reached; X4: maximum acceleration reached; X5: center of gravity in X; X6: center of gravity in Y). The means establish differences between independent groups, both in variable X1 (group 1: ≈66°; group 2: ≈70°; p=0.247 ), X2 (group 1: ≈73°; group 2: ≈86°; p=0.002 ), X3 (group 1: ≈1.03m/s; group 2:≈1.36m/s; p=0.017 ), X4 (group 1: ≈2.93m/s2; group 2: ≈4.78m/s2; p=0.011 ), X5 (group 1: ≈0.43m; group 2:≈0.65m; p=0.000 ), and X6 (group 1: ≈0.61m; group 2: ≈0.83m; p =0.000 ). Group 1 has a more effective technique, while the amateurs have less efficiency in biomechanical movement due to their inexperience, high values are shown in speed and acceleration, movement angles such as hip angles are included.

Omega-3 Fatty Acids for Sport Performance-Are They Equally Beneficial for Athletes and Amateurs? A Narrative Review.

Omega-3 fatty acids, specifically eicosapentanoic acid (EPA, 20:5n-3) and docosahexanoic acid (DHA, 22:6n-3) are receiving increasing attention in sports nutrition. While the usual focus is that of athletes, questions remain if the different training status between athletes and amateurs influences the response to EPA/DHA, and as to whether amateurs would benefit from EPA/DHA supplementation. We critically examine the efficacy of EPA/DHA on performance, recovery and injury/reduced risk of illness in athletes as well as amateurs. Relevant studies conducted in amateurs will not only broaden the body of evidence but shed more light on the effects of EPA/DHA in professionally trained vs. amateur populations. Overall, studies of EPA/DHA supplementation in sport performance are few and research designs rather diverse. Several studies suggest a potentially beneficial effect of EPA/DHA on performance by improved endurance capacity and delayed onset of muscle soreness, as well as on markers related to enhanced recovery and immune modulation. The majority of these studies are conducted in amateurs. While the evidence seems to broadly support beneficial effects of EPA/DHA supplementation for athletes and more so in amateurs, strong conclusions and clear recommendations about the use of EPA/DHA supplementation are currently hampered by inconsistent translation into clinical endpoints.

Valuing Shorebirds: Bureaucracy, Natural History, and Expertise in North American Conservation.

This article follows shorebirds-migratory animals that have gone from game to nongame animals over the course of the past century in North America-as a way to track modern field biology, bureaucratic institutions, and the valuation of wildlife. Doing so allows me to make interrelated arguments about the history of wildlife management and science. The first is to note the endurance of observation-based natural history methods in field biology over the long twentieth century and the importance of these methods for the persistent contribution of amateurs. The second major line of argument advances the historical significance of scientific, government bureaucracies as sites of natural knowledge production. Historians of biology and ecology have tended to stress scientists with institutional homes in universities, museums, and at land-grant field stations-particularly as various forms of field biology became professionalized over the twentieth century. In contrast, migratory animals like shorebirds, whether under the auspices of the US Biological Survey or the contemporary Fish and Wildlife Service, were primarily studied and conserved by biologists in bureaucratic agencies. Mid- to low-level bureaucrats, along with avocational birders, have mainly been responsible for developing what we know about shorebird migration, behavior, and life history. And third, shorebirds foreground the importance of bureaucratic context for the valuation of nature, from their economic value to agriculture in the early twentieth century to their value as rare, endangered species in the twentyfirst.

Influence of Contextual Variables on Physical and Technical Performance in Male Amateur Basketball: A Case Study.

Currently, most basketball research is focused on professional and elite players. Studies at the amateur level are important to explain the physical and technical demands of competition and thus improve players' and teams' performance. The purpose of the present study was to describe the competitive demands of an amateur-level basketball team and to analyze the influence of different situational variables on the physical and technical performance indicators. Eleven amateur senior basketball players participated in six official final-round games during the 2018/2019 season. External, internal load, and notational analysis were registered by inertial devices, heart rate bands, and video analysis. The Kruskal-Wallis H-test was applied for comparisons based on playing positions, periods, and final quarter game outcome, with the post hoc comparison accomplished by a Mann-Whitney U test. The Spearman correlation coefficient was realized for the relational analysis. The results showed that: (a) guards covered more volume of displacements (effective on-court time: p < 0.01, E R 2 = 0.05; steps/min: p < 0.01, E R 2 = 0.28) and the centers performed competitive actions of higher load ([>8G] Imp/min: p < 0.01, E R 2 = 0.20; jumps/min: p < 0.01, E R 2 = 0.33); (b) a performance decreasing was found between the first and second half of the game; (c) in balanced matches there was the most individual technical performance (PIR/min: p < 0.98, E R 2 = 0.01), while in the unbalanced games more high-intensity impacts were seen ([>8G] Imp/min: p < 0.01, E R 2 = 0.07). The situational variables analyzed had an influence on athletic performance in amateur senior basketball players and should be considered for designing training sessions and planning strategies during official matches.

Impacto de la pandemia por covid-19 en los deportistas / Impact of the covid-19 pandemic on athletes

La pandemia del covid-19 afectó a todo el planeta, alterando la salud, la libertad, la economía, la cultura y la seguridad. El mundo del deporte no quedó al margen de esta situación. Los deportistas debieron confinarse como el resto de la población, pero esto implicó para ellos un desentrenamiento prolongado (más de cuatro semanas) que provocó la pérdida de muchas de las adaptaciones físicas y psicológicas que genera el entrenamiento. Se generaron alteraciones en los sistemas cardiorrespiratorio, inmune y osteomuscular y endócrino, en el metabolismo, y un aumento de masa grasa en detrimento de la masa magra, lo que puede generar lesiones en el regreso a la actividad. Se tomaron medidas paliativas para que el desentrenamiento no fuera tan profundo, pero, como su nombre lo indica, estas medidas no reemplazan totalmente el entrenamiento. (AU)

The covid-19 pandemic has been affecting the worldwide, not only in relation to the health but also to the liberty, the economy, the culture and the security. However, sports have not been the exception. The athletes fell into confinement as the rest of the population, but these led to a prolonged detraining, (more than four weeks), which caused the loss of all physical and psychological adaptation generated by training. Some alterations were observed in the cardiorespiratory system, in the immunity, in the osteo-muscular apparatus, in the metabolic system, in the endocrine system and in the increase in fat mass at the expense of lean mass, which can cause injuries during the return to activity. Palliative measures were taken so that detraining wasn't so deep, but as the name implies, this measures do not totally replace training. (AU)

Naming names: the first women taxonomists in mycology.

The transition from amateur to professional in natural history is generally regarded as having taken place in the nineteenth century, but landmark events such as the 1917 appointment of mycologist Johanna Westerdijk (1883-1961) as the first female professor in the Netherlands indicate that the pattern of change for women was more varied and delayed than for men. We investigate this transition in mycology, and identify only 43 women in the Western World who published scientific mycological literature pre-1900, of whom twelve published new fungal taxa. By charting the emergence of these women over time, and comparing the output of self-taught amateurs and university graduates, we establish the key role of access to higher education in female participation in mycology. Using a suite of strategies, six of the self-taught amateurs managed to overcome their educational disadvantages and name names - Catharina Dörrien (the first to name a fungal taxon), Marie-Anne Libert, Mary Elizabeth Banning, Élise-Caroline Bommer, Mariette Rousseau, and Annie Lorrain Smith. By 1900, the professional era for women in mycology was underway, and increasing numbers published new taxa. Parity with male colleagues in recognition and promotion, however, remains an ongoing issue.

Motivos de participación en una carrera de fondo, según edad, sexo y experiencia deportiva, en corredores aficionados / Amateur runners' motivations for participating in long-distance races by age, gender, and sports experience / Motivos de participação em uma corrida de fundo, segundo idade, sexo e experiência esportiva em corredores amadores

Resumen Rosales-Obando, D.M.; Araya-Vargas, G. y Rivas-Borbón, O.M. (2018). Motivos de participación en una carrera de fondo, según edad, sexo y experiencia deportiva en corredores aficionados. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 16(1), 1-18. Propósito: examinar los motivos de corredores aficionados para participar en una carrera atlética de fondo, considerando su grupo de edad, experiencia deportiva y sexo. Participaron 404 personas (18 a 88 años; n=271 hombres y n=133 mujeres; entre 2 meses y 40 años de experiencia deportiva; ninguno profesional). Resultados: los motivos para correr relativos al control de peso tienden a perder valor conforme aumenta la experiencia deportiva (hombres r=-.121; p=.046; mujeres r=-.187; p=.031), y los motivos de superación de metas y competición tienden a disminuir su importancia conforme se avanza en edad (hombres r=-.231; p<.001; mujeres r=-.207; p=.017). Este patrón fue similar para ambos sexos. Además, tanto en los hombres como en las mujeres, sus motivos principales para correr fueron los motivos de reconocimiento y los motivos relacionados con significado de vida y autoestima. Conclusión: pese a la naturaleza amateur de la muestra y a su falta de preparación deportiva profesional para competir en carreras de fondo, su perfil motivacional, indistintamente del sexo, se caracteriza por la búsqueda de reconocimiento, significado de vida y autoestima mediante la práctica de esa actividad. Además, los motivos de salud explican poca varianza de la motivación para correr de esta muestra, tanto en hombres como en mujeres.

Abstract Rosales-Obando, D.M.; Araya-Vargas, G. & Rivas-Borbón, O.M. (2018). Amateur runners' motivations for participating in long-distance races by age, gender, and sports experience. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 16(1), 1-18. Purpose: examine amateur runners' motivations for participating in long-distance races, taking into consideration age, sports experience and gender. A total of 404 amateur runners participated (18 to 88 years of age, n=271 men and n=133 women, between 2 months and 40 years of sports experience, none professional). Results: motivations related to weight control tend to lose value as sports experience increases (men r=-.121; p=.046; women r=-.187; p=.031), while motivations related to overcoming goals and competition tend to decrease as age advances (men r=-.231; p<.001; women r=-.207; p=.017). This pattern was similar for both sexes. In addition, both men and women's main motivations for running were recognition and finding meaning to life and self-esteem. Conclusion: despite the amateur nature of the subjects and their lack of professional sports preparation to compete in long-distance races, their motivational profile, regardless of sex, is characterized by the search for recognition, finding meaning to life and self-esteem through the practice of this activity. In addition, health reasons explain little variance in the motivation for running in the sample, both men and women.

The effects of full marathon on hemodynamics related to cardiac electrophysiology of marathon amateurs / 中华急诊医学杂志

Objective To observe and assess the effects of full marathon on hemodynamics and cardiac electrophysiology of marathon amateurs without adverse event after the race.Methods Fiftyone subjects were included in the final analysis of the study,blood pressure,heart rate,body surface electrocardiogram (ECG) of all subjects under static status before the race and within (15-30) min after the race were detected,and sufficient amounts of the peripheral blood and the radial arterial blood specimens of all subjects under static status before the race and within (15-30) min after the race were collected instantly.The peripheral blood was used for measuring markers of muscle injury and NT-proBNP,and the radial arterial blood was taken for blood gas analysis.The QTc interval,QRS,PR interval,and QTd interval were recorded from the 12-lead ECG report.Results Compared with those under static status before the race,the systolic blood pressure,diastolic blood pressure,mean arterial blood pressure and heart rate of all the subjects within (15-30) min after the race were significantly higher (P＜0.05).When the markers of striated muscle injury were compared before and after the competition,levels of CK,cTNI,LDH,and myoglobin after the race were significantly increased compared with them under static status before the race (P ＜0.05),and the level of NT-proBNP after the race was also significantly increased compared with it before the race (P＜0.05).When blood gas analysis before the race was compared with that after the race,the PH values after race were significantly lower than it before race (P＜0.05).The level of lactic acid after the race was significantly higher than it before race (P＜0.05).After the race,the levels of PCO2,SBE and HCO3-decreased significantly compared with those before race (P＜0.05),and the QTc and QTd intervals after the race increased significantly compared with those before the race,however,the QTc interval and QTd interval for all subjects before and after the competition were within the normal range.Conclusions Full marathon significantly affect the myocardial electrophysiological markers of healthy amateur athletes without chronic diseases,but those markers fluctuate within the normal range.

Self-Administration of Medicines and Dietary Supplements Among Female Amateur Runners: A Cross-Sectional Analysis.

INTRODUCTION: Self-administration of medicines or dietary supplements without any physician's advice is a widespread behavior and appears to be more frequently practiced by women. Moreover, reasons to self-administer products are often pains and injuries especially among athletes who might also use remedies to improve physical performance. The objective of this study was thus to assess the prevalence of self-administration of medicines and dietary supplements as well as its determinants among female amateur runners. METHODS: Our sample was comprised of women who took part in amateur running events. Data regarding self-administration of substances, exclusively aiming at being physically prepared for the running event (i.e., intake the week before), were collected through an anonymous self-administered questionnaire including four specific themes (i.e., general information, self-administered medicines and dietary supplements, context of self-administration of substances and knowledge of the anti-doping regulations). RESULTS: A total of 136 women, with a median age of 39 years (interquartile range: 27-47), volunteered. Among them, 34.6% reported self-administration of medicines during the period immediately preceding the running event, with the aim to be physically prepared. More than one third (33.8%) also declared self-administration of dietary supplements. Furthermore, we observed that about 8.1% of the sample had consumed a potentially doping substance. After adjustments for confounding variables, the probability of self-administration of products (medicines or supplements) increased significantly with the intensity of the activity and the membership in a sports club. CONCLUSIONS: Our study showed that self-administration of products among female runners seems to be a widespread behavior, where the intensity of the sports practice and the network of runners seem to influence the decision to resort to this behavior.

The Too-Much-Precision Effect.

Past research has suggested a fundamental principle of price precision: The more precise an opening price, the more it anchors counteroffers. The present research challenges this principle by demonstrating a too-much-precision effect. Five experiments (involving 1,320 experts and amateurs in real-estate, jewelry, car, and human-resources negotiations) showed that increasing the precision of an opening offer had positive linear effects for amateurs but inverted-U-shaped effects for experts. Anchor precision backfired because experts saw too much precision as reflecting a lack of competence. This negative effect held unless first movers gave rationales that boosted experts' perception of their competence. Statistical mediation and experimental moderation established the critical role of competence attributions. This research disentangles competing theoretical accounts (attribution of competence vs. scale granularity) and qualifies two putative truisms: that anchors affect experts and amateurs equally, and that more precise prices are linearly more potent anchors. The results refine current theoretical understanding of anchoring and have significant implications for everyday life.

Citizen science networks in natural history and the collective validation of biodiversity data.

Biodiversity data are in increasing demand to inform policy and management. A substantial portion of these data is generated in citizen science networks. To ensure the quality of biodiversity data, standards and criteria for validation have been put in place. We used interviews and document analysis from the United Kingdom and The Netherlands to examine how data validation serves as a point of connection between the diverse people and practices in natural history citizen science networks. We found that rather than a unidirectional imposition of standards, validation was performed collectively. Specifically, it was enacted in ongoing circulations of biodiversity records between recorders and validators as they jointly negotiated the biodiversity that was observed and the validity of the records. These collective validation practices contributed to the citizen science character or natural history networks and tied these networks together. However, when biodiversity records were included in biodiversity-information initiatives on different policy levels and scales, the circulation of records diminished. These initiatives took on a more extractive mode of data use. Validation ceased to be collective with important consequences for the natural history networks involved and citizen science more generally.

Individual variability in cardiac biomarker release after 30 min of high-intensity rowing in elite and amateur athletes.

This study had two objectives: (i) to examine individual variation in the pattern of cardiac troponin I (cTnI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) release in response to high-intensity rowing exercise, and (ii) to establish whether individual heterogeneity in biomarker appearance was influenced by athletic status (elite vs. amateur). We examined cTnI and NT-proBNP in 18 elite and 14 amateur rowers before and 5 min, 1, 3, 6, 12, and 24 h after a 30-min maximal rowing test. Compared with pre-exercise levels, peak postexercise cTnI (pre: 0.014 ± 0.030 µg·L(-1); peak post: 0.058 ± 0.091 µg·L(-1); p = 0.000) and NT-proBNP (pre: 15 ± 11 ng·L(-1); peak post: 31 ± 19 ng·L(-1); p = 0.000) were elevated. Substantial individual heterogeneity in peak and time-course data was noted for cTnI. Peak cTnI exceeded the upper reference limit (URL) in 9 elite and 3 amateur rowers. No rower exceeded the URL for NT-proBNP. Elite rowers had higher baseline (0.019 ± 0.038 vs. 0.008 ± 0.015 µg·L(-1); p = 0.003) and peak postexercise cTnI (0.080 ± 0.115 vs. 0.030 ± 0.029 µg·L(-1); p = 0.022) than amateur rowers, but the change with exercise was similar between groups. There were no significant differences in baseline and peak postexercise NT-proBNP between groups. In summary, marked individuality in the cTnI response to a short but high-intensity rowing bout was observed. Athletic status did not seem to affect the change in cardiac biomarkers in response to high-intensity exercise.
