Windsurfing’s Rapid Global Diffusion: The Evolution of a 1970s Technology-First Sport

There has been considerable academic interest in what has been variously labelled new, lifestyle or, as used here, technology-first sport. This category of participatory sport covers a wide range of activities – among them windsurfing. Like some other sports initially relying on the development of technological equipment, it spread across the world from California. Technology-first sport is positioned as a useful lens, and this is applied to windsurfing showing the value of exploring a sport’s development from this perspective. Distinctive elements of windsurfing’s early history are explored that relate to its rapid growth being intimately linked to technological evolution, intellectual property battles and globalisation processes. The genesis of the sport is contextualised in terms of favourable Californian circumstances and the trajectory of the American plastics industry at the time. Its diffusion across 1970s Europe featured intense technological and market competition which created a rapid evolution of the sport before consolidation. Distinct periods of evolution from 1970 to 1990 are evaluated. These include diffusion processes and the influence of national socio-political factors as it spread to Eastern Europe and to China. A final reflection of the present-day technology fragmentation of windsurfing further reinforces how use of a technology-first sport lens has value.

Exercise-induced cardiac remodelling in elite athletes is characterized by a stronger ventricular mass-volume association in females as compared with males: MRI results from the ELITE cohort

Abstract Background Differentiation between exercise-induced cardiac remodelling (EICR) and cardiac pathology constitutes a central challenge in sports cardiology. To assist clinicians, theoretical frameworks have been developed: i.e. dynamic sports are associated with ventricular dilatation, static sports with hypertrophy, and sports containing both components with both dilatation and hypertrophy. However, EICR frameworks have been almost exclusively based on findings in male athletes, and whether these associations are found in female athletes is to date unclear. Purpose We aimed to investigate intersex differences in left ventricular (LV) remodelling in the extreme phenotypes of elite athletes. Methods We included 227 healthy, elite athletes from the ELITE cohort who underwent cardiac magnetic resonance imaging (CMR). Our outcomes of interest were absolute and body surface area (BSA) indexed LV end-diastolic volume, LV end-diastolic wall mass, LV end-diastolic mass-volume ratio to express cardiac remodelling (LV end-diastolic wall mass / LV end-diastolic volume) and correlations of BSA-indexed LV mass with LV end-diastolic volume to compare LV remodelling between sexes. Results A total of 122 male and 105 female elite athletes (age 26±6 years) were included. The age and division in sports categories according to the ESC classification were similar between the sexes. Male athletes showed larger indexed LV end-diastolic volumes (127±19 versus 108±14 ml, p <0.001) and indexed LV wall mass (66±12 versus 50±11 grams, p <0.001) compared to female athletes. Male athletes had a proportionally larger LV mass-volume ratio than women (0.53±0.12 versus 0.46±0.09 g/ml, p <0.001). Female elite athletes showed a moderate association between indexed LV mass increase with indexed LV end-diastolic volume increase (Spearman’s rho 0.45, p <0.001), whereas male athletes showed a weak association (Spearman’s rho 0.25, p =0.006). Conclusions Elite male athletes have larger left ventricular volumes and wall mass, with a greater mass-volume ratio, than their female counterparts. However, female athletes demonstrate a stronger mass-volume association than males. Our findings suggest the presence of distinct sex-dependent features of EICR.

Sport-specific cardiac adaptation in 104 female elite athletes: MRI findings from the ELITE cohort

Abstract Background The overlap between exercise-induced cardiac remodelling (EICR) and cardiac pathology is a key challenge in sports cardiology. Mainly based on findings in male athletes, EICR is thought to be sport-specific, and varyingly characterised by increased ventricular volumes, cardiac mass and/or wall thickness. However, no large cardiac magnetic resonance imaging (CMR) study in female elite athletes has extensively examined sport-specific cardiac adaptations. Purpose To investigate sport-specific EICR on CMR in a large cohort of female elite athletes. Methods We performed a cross-sectional CMR analysis in female elite athletes (Para-/Olympic or professional athletes competing ≥10 hours per week at a national/international level) aged ≥16 years, included in the ELITE cohort (1). We excluded athletes with known cardiovascular disease, and classified athletes according to the ESC sports disciplines classification. Our outcomes of interest were sport-specific EICR, defined as BSA-indexed LV and RV end-diastolic volume (EDVi), LV wall mass (LVMi), and maximal LV wall thickness (LVWdmax), LV remodelling index (LVMi/LVEDVi), and LV/RV ratio (LVEDi/RVEDVi). CMR was performed according to a uniform protocol, preferentially on 1.5T. A dedicated core-lab analysed all CMRs in Circle Cardiovascular Imaging. Results We included 104 female elite athletes, 96% Caucasian, mean age of 26.1 ±5 years, BSA 1.8 ±0.1 m2, and mean professional (≥10 hours/week) athlete years of 11.6 ±5. The athletes were classified as skill (n=8), power (n=9), mixed (n=39) and endurance (n=48) sports. Endurance athletes had markedly increased left- and right ventricular volumes compared to power (LVEDVi 111.2 ±15 vs 98.7 ±11 ml/m2, p=0.009; RVEDVi 114.8 ±18 vs 101.7 ±10 ml/m2, p=0.006) and mixed athletes (LVEDVi 111.2 ±15 vs 107.3 ±13 ml/m2, p=0.058; RVEDVi 114.8 ±18 vs 107.8 ±12 ml/m2, p=0.031) (Figure 1). No differences were found between endurance, mixed, power and skill athletes in LVEDVi/RVEDVi ratios (0.97 vs 0.99 vs 0.97 vs 0.99), LVMi (52.6 ±12 vs 46.9 ±10 vs 48.7 ±10 vs 50.4 ±11 g/m2) (Figure 2), LVWdmax (8.1 ±1 vs 7.9 ±1 vs 7.9 ±1 vs 8.9 ±1 mm), LV remodelling index (LVMi/LVEDVi 0.47 vs 0.44 vs 0.49 vs 0.48), LV ejection fraction (56.3 ±4 vs 56.7 ±5 vs 58.2 ±3 vs 57.7 ±3 %), and RV ejection fraction (54.6 ±4 vs 55.7 ±4 vs 55.4 ±3 vs 56.7 ±4). Conclusion In female elite athletes, EICR according to sport categories is mainly characterised by balanced increases in ventricular volumes in endurance athletes, but not in increases in left ventricular wall-mass and thickness, even in sport categories with high static demands. Our findings constitute a first step towards the understanding of sport-specific EICR in female elite athletes.Figure 1.Figure 2.

Immunological indexes for assessing parameters of cardiovascular system in athletes of different qualification

Timely diagnosis and prevention of cardiovascular diseases is based on markers that detect changes in the athlete’s body at an early stage of disease. To implement this task, it is important to use novel laboratory techniques. We have carried out a comparative determination of immunological markers, specific antibodies to angiotensin, bradykinin, histamine, dopamine, serotonin and functional indicators of the cardiovascular system in athletes of various qualifications. The object of study included athletes of the Russian national teams who underwent an in-depth examination (IME) as part of medical survey. The participants were divided into groups depending on the sport arts and qualifications. Representatives of the group “Cyclic sports” included athletes without a category of 30 people and 29 qualified athletes (1st step, Candidate Master, Master of Sports, etc.). The “Combat sports” group consisted of 32 people without a category and 31 athletes with qualifications similar to those indicated above. Athletes of “Speed-strength” sports are represented by a group of 31 people without a category and 29 athletes with qualifications. The functional parameters of the cardiovascular system included analysis of heart rate, systolic blood pressure and diastolic blood pressure, which were compared with control values established for the athletes. The immunological indexes were determined in blood serum of the athletes and in subjects from control group by means of the solid-phase ELISA method using conjugated antigens of angiotensin, bradykinin, histamine, dopamine, serotonin for absorption on the plates. To compare the indexes, a control group of 30 people without cardiovascular symptoms was examined. Diastolic blood pressure for athletes of cyclic sports and combat sports was below the control values, and, for athletes of speed-strength sports, it was higher than in control group. A decrease in diastolic blood pressure for the above subgroup of athletes may indicate characteristic adaptive physiological changes in myocardium. The levels of immune-related indexes for serotonin, dopamine for the athletes of all groups corresponded to the control values. The only exception concerned qualified athletes of cyclic sports, which significantly differed from the normal values, compared to athletes without a sports category. Significantly high immunological parameters for histamine and angiotensin did not depend on the athlete’s qualification. In athletes involved in speed-strength sports, the levels of indexes for bradykinin did not differ from the normal values, and, for athletes in cyclic sports and combat sports, they significantly exceeded the norm.We have shown that different levels and types of sports activities affect the performance of cardiovascular system in their own way. The changes in immunological parameters reflect regulatory state of cardiovascular system. Accordingly, their simultaneous increase against the control may indicate participation in the development of cardiovascular diseases. The differences in their levels for athletes involved in combat sports, cyclic and speed-strength sporting activities show deeper changes in regulatory systems associated with duration and level of physical activities.

Influence of sport type and gender on bone turnover markers in young athletes

BackgroundExercise is beneficial to bone health. However, little is known about the interaction effect of gender and sport type on bone turnover in young athletes. This study aimed to examine the influence of gender and sports categories (high, medium, and low impact) on bone turnover: reabsorption markers–osteocalcin, calcium, inorganic phosphate (IP), alkaline phosphatase (ALP), and resorption marker–cross-linked N-telopeptides of type 1 collagen (NTx) among a university’s undergraduate athletes.MethodsThe study was an ex-post facto design involving forty-seven purposively recruited gender- and sport-type-matched undergraduate athletes whose demographic characteristics and BMI were obtained. Participants’ 5 mL antecubital blood samples were collected and analysed for serum levels of osteocalcin, calcium, IP, ALP, and NTx using standard laboratory protocols, Bio-Tek spectrometer, and KC4 (3.3) software. Data were analysed using descriptive statistics and two-way ANOVA.ResultsThe study involved 24 females and 23 males (n = 47) aged 22.15 ± 3.35 years with an average BMI of 23.34 ± 4.66. There was no significant gender effect on the biomarkers. However, there was a significant effect of the sports category on IP (F = 4.307, p = 0.020), calcium (F = 6.807, p = 0.003), and ALP serum levels (F = 11.511, p < 0.001). Specifically, mid-impact sports participants had a higher IP than the low-impact group (mean difference [MD] = 0.81 mg/dL, p = 0.036). Low-impact had a higher calcium level than mid-impact (MD = 0.40 mg/dL, p = 0.022) and high-impact (MD = 0.49 mg/dL, p = 0.003). Conversely, low-impact had lower ALP than mid-impact (MD = − 11.13 U/L, p = 0.013) and high-impact (MD = − 17.44 IU/L, p < 0.001).ConclusionModerate to high-impact sports positively affected bone turnover in young athletes. However, gender had no significant impact.

Heranwachsende in der cyber-physischen Stadt – Kategorien hybrider Sport- und Bewegungswelten aus Sicht der Stadtplanung

ZusammenfassungDigitale Hilfsmittel wie Navigations- oder Tracking-Apps verändern Bewegung in der Stadt. Digitalisierungsprozesse von Sport- und Bewegungsaktivitäten sind kaum Gegenstand raumwissenschaftlicher Forschungen, gleichzeitig veranschaulichen sie – insbesondere aus Sicht der Stadtplanung – die transformativen Kräfte in Städten an der Schnittstelle von Digitalität, Raum und Bewegungserleben. Denn bisher werden hybride Sportformen in erster Linie sichtbar durch die zunehmende Beanspruchung öffentlicher Räume. Digitale Raumaneignung findet ausgehend von Plattformen, Communities und weiteren Online-Angeboten bereits überall statt. Infolge der Vermischung von online, offline und hybriden Settings stehen nicht nur die Koordination und Gestaltung von öffentlichen Grünanlagen sowie Sportinfrastruktur unter Veränderungsdruck. Es geht darum, ein grundlegendes Vokabular zur Neuorganisation von Bewegungsaktivitäten und Stadträumen zu formulieren. Im Fokus des Beitrags stehen deshalb vor allem Anknüpfungspunkte für die qualitative Raumforschung und Digitalisierungsforschung: Anhand einer bundesweiten Online-Befragung (n = 861) werden Eigenschaften für sportaffine Heranwachsende (Altersgruppe 15–19 Jahre, n = 128, und Altersgruppe 20–24 Jahre, n = 152) mittels der folgenden Kategorien vorgestellt: Akteur*innen, digitale Hilfsmittel, Sport‑/Bewegungsformen, Orte und Infrastrukturen, Angebote und Aktivitäten. Die systematische Stichprobe kombiniert Ergebnisse aus Gruppendiskussionen (n = 31) mit Akteur*innen aus der Plattformökonomie, Sportunternehmen, Verwaltungen und Zivilgesellschaft. Diese Analyse der Raumproduktion Heranwachsender stößt Fragen zum Einfluss der Digitalisierung auf soziale Prozesse sowie zu sich verändernden Orten und zukünftiger Planung an. Schließlich werden Einblicke in die alltäglichen Sporterlebnisse der eher informellen Lebenswelt von Jugendlichen sowie jungen Erwachsenen für ein transdisziplinäres Forschungsfeld offeriert. Innerhalb einer vielschichtigen Gemengelage bietet der Beitrag einen Überblick anhand eines erneuerten und gegenwartsnahen Kategorisierungssystems hybrider Sport- und Bewegungswelten für Forschung und Praxis an.

Edukasi Penanganan Cedera Akut Pada Komunitas Bulutangkis Di Gor Bello, Laweyan : Metode RICE

Badminton is included in the category of non-contact sports which can be played individually or in groups, where the game of badminton requires many combinations of movements such as stepping, jumping, lunges, and quite a bit of acceleration and arm movement. Usually a badminton match from the start of the game to the end takes around 30-90 minutes or more, this shows that badminton is a sport that requires good body condition. Musculoskeletal complaints are a disease caused by repetitive work or unergonomic working methods. Musculoskeletal disorders (MSDs) usually appear as pain in the nerves, muscles or tendons. In Indonesia alone, the prevalence of Musculoskeletal Disorders (MSDs) is 11.9% based on diagnosis by health workers, whereas if seen based on symptoms the prevalence is 24.7%. The aim of this activity is to gain insight into the first treatment for sports injuries in badminton players in Gor Bello, Laweyan. This activity carried out counseling using the lecture method using poster media and evaluation of knowledge of injury management was carried out using a questionnaire both before and after providing the counseling. The conclusion of this community activity is that education regarding handling injuries to badminton players has had a positive impact in increasing knowledge among badminton players at Gor Bello Laweyan regarding handling badminton sports injuries using the RICE method.

Comparison of Body Compositions among Endurance, Strength, and Team Sports Athletes

Regular monitoring and evaluation of body composition determine an athlete’s output, such as their probability of winning competitions. The purpose of this study was to analyze the differences in athletes’ body composition among several sports categories. The data collected were on 251 athletes aged 20 to 30 years during the pre-competition period. The subjects were divided into three groups: endurance, power, and team sports. SECA 515mBCA was used to analyze the athletes’ body composition, which included their body fat percentage (BFP), fat mass (FM), fat-free mass (FFM), skeletal muscle mass (SMM), total body water (TBW), and extracellular water (ECW). The results showed that all body composition parameters were lowest in the endurance category. Fat composition was lowest in the endurance category but did not differ significantly between categories in male athletes. Meanwhile, in female athletes, there was a significant difference in FM between sports categories (p=0.009). FFM, SMM, TBW, and ECW differed significantly between categories (p&lt;0.05). In female athletes, these variables were higher in the team sports category, as opposed to the power category among male athletes. This study concluded that there were differences in lean body mass composition between sport categories, while fat mass did not differ between sport categories in male athletes. This can be attributed to the differences in training programs and needs of each sport category in maximizing performance. These findings can provide advice to sports professionals that each sport category has its own body composition specifications.

Prevalence and Association of Exercise Dependence and Eating Disorder Risk in Collegiate Student-Athletes.

Exercise dependence (EXD) is a compulsive and addictive behavior that can negatively affect physical and mental health, leading to significant impairment or distress. Exercise dependence has been associated with symptoms of eating disorders (EDs). Student-athletes are an at-risk population for EXD and EDs given the physical and psychological demands of competitive sports. To examine the EXD and ED risks in student-athletes across sex and sport category and to determine the association between EXD and ED. Cross-sectional study. Collegiate athletics. National Collegiate Athletic Association Division I and II student-athletes (n = 1885; age = 19.8 ± 1.4 years; females = 69.6%, n = 1312; males = 30.4%, n = 573). A web-based survey including demographics, the Exercise Dependence Scale-21, the Eating Attitudes Test-26, and questions about pathogenic behaviors. Overall, 4.9% (n = 92) of the student-athletes were categorized as at risk for EXD (females = 4.8%, n = 63/1312; males = 5.1%, n = 29/573), with differences across sex and sport categories (all: χ28,1885 = 99.1, P < .001). The ED risk in student-athletes (Eating Attitudes Test-2, pathogenic behavior use, or both) was 22.7% (n = 428; females = 25.5%, n = 334/1312; males = 16.4%, n = 94/573), with differences by sex (χ24,1885 = 10.1, P = .039). Multiple logistic regressions indicated a significant association between the risks of EXD and ED for all student-athletes; athletes at risk for EXD were also at greater risk for EDs (odds ratio = 5.104; 95% CI = 3.237, 8.046) than nondependent-asymptomatic athletes (odds ratio = 2.4068; 95% CI = 1.5618, 3.7089). Although physical activity has become a public health intervention to improve overall health in populations, EXD can be considered a problem related to physical activity. Exercise dependence can negatively affect physical and mental health, whereas EDs may be psychiatric disorders influenced by EXD, as exercise can be a compensatory behavior to achieve weight loss. To minimize the overall risk of EDs in student-athletes, additional education and awareness are needed. Special attention should be given to any student-athletes, in particular females, who display signs of EXD.

Testosterone, Sex, and Sport

Recent policies banning or limiting the participation of transgender and intersex women from the women's category of sport have called upon the science of testosterone to justify exclusion and define eligibility criteria. Scientific evidence supports a male advantage in sport, substantial sex differences in circulating testosterone, permanent effects on physiology from its long-term exposure, and a dose-dependent sporting advantage to its exogenous use. Yet, evidence connecting these findings has major gaps. Notably, no direct evidence shows that transgender and intersex women have a systematic sport advantage or that testosterone is the causal link. A brief review covers the relevant societal context, the science of testosterone, and the existing data used to support policies of exclusion. Key complexities, gaps in knowledge, and related ethical concerns all point to the need for more rigorous research.

Sensory Mechanisms for Precise Movement Control of Athletes

Purpose. To establish the variability of the state of sensory systems and the dependence of control on the precise movements of basketball players from various sensory functions. Investigate. 30 basketball players of the student league at the age of 17–18 years who had a level of preparation of the first sports category and candidate for the master of sports. Result. Established a reliable level of communication between the functions of kinesthetic, visual, vestibular analyzer and the dependence of the accuracy of ball throwing into the basket from individual sensory functions. Conclusion. Results of the conducted researches have determined the sensory regularities of the control by precision throw movements. Studies have established that the accuracy depends on the intensity of the training exercises. Game activity of basketball players occurs at a very high intensity. Therefore for improving the accuracy of throwing the ball requires sensory functions to train with intensity of the exercises, close to the competitive activity.

Perspective directions of motorcycle tourism development in the western territories of ukraine during the war and post-war period

The article defines the concept of motorcycle tourism as an active recreation, which consists in travelling on a motorcycle on routes with tourist objects of excursion nature. The main differences of such motorcycle tours from sports motorcycle tourism, focused on obtaining sports categories and titles, are analysed - refusal to deliberately complicate the route, division of tours into categories of complexity and combination of the sports component of the tour with the inspection of cultural and natural attractions. It is substantiated that the complexity of such hikes can range from simple to extremely high, and the routes are laid out in such a way as to take advantage of the advantages offered by a motorcycle for fast movement along the route. The article briefly describes the development of tourist motorcycle traffic in the western territories of Ukraine and the problems it has encountered recently. The classification of types of motorcycles in terms of their suitability for travelling is presented. The author suggests ways to reorient the flow of motorcycle tourists to the western part of Ukraine due to the increased risk of being hit by explosive devices when travelling through the territory that was under occupation or in close proximity to the war zone. A number of attractive motorcycle tourist routes have been developed in western Ukraine during the war and post-war period.

Planning Life Outside of Sport: Elite Aathletes’ Help-seeking Behaviours Toward Career Support Resources

Despite results showing that planning the transition out of sport is associated with more positive emotional responses and fewer emotional difficulties in retirement, only a small proportion of athletes are using the resources available through support programs. This study investigates factors associated with the help-seeking behaviours toward career support resources of 191 surveyed elite athletes of Canada. Information on perceived barriers to help-seeking, the level of engagement to a career outside of sport, and the use of resources was collected using a survey. Results from descriptive and predictive analysis indicate three main perceived barriers to help-seeking: lack of time (51.8%), lack of knowledge (35.1%) and a fear of stigma associated with the use of career support resources (12.6%). Athlete age, sport category (winter, summer) and level of engagement in a career outside of sport are predictors of the use of career support resources.

Summer Olympic sports and female athletes: comparison of anti-doping collections and prohibited substances detected in Australia and New Zealand vs. France.

Like any athlete, female athletes may be tempted to use prohibited substances during competition or training to enhance their performance. Anti-doping tests performed on female athletes in summer Olympic sports from two geographical areas: Australia/ New Zealand, and France were compared. First, the distribution of sample collections across different sports disciplines, as well as the distribution of substances was investigated. Then the distribution of collections and substances detected in the five sports categories (Strength/Speed, Endurance, Mixed, Motor Skills with High Energy Expenditure, and Motor Skills with Low Energy Expenditure) were studied with consideration of therapeutic use exemptions obtained by the athlete. Australia/New Zealand and France were similar in their overall number of anti-doping collections performed. Likewise, both regions had the same sports disciplines (athletics, aquatics, cycling) and sport categories (Mixed and Endurance) as having the highest number of sample collections. The Motor Skills with High Energy Expenditure, and Motor Skills with Low Energy Expenditure categories had the lowest number of sample collections. However, the number of substances detected was significantly different (p < 0.05) with a greater number of substances found in the French data. There were a few substances in common between the two geographical areas, namely prednisone/prednisolone, carboxy-THC, terbutaline, vilanterol and methylphenidate, but most were different. In-competition tests were the category where most of the AAFs were found.

Cross-sectional study on ankle sprain and its related factors in physical education college

To explore prevalence, risk factors and treatment of ankle sprain of young college student , in order to obtain accurate epidemiological data. From March 2019 to May 2019, 552 college students(1 104 sides of anke joints) from Xi'an Physical Education university were enrolled in study according to inclusion and excludion standard, including 309 males and 243 females aged from 16 to 24 years old with an average of (20.9±3.7) years old. Age, gender, and body mass indes(BMI) etc were recorded. Morbidity of acute and chronic ankle sprains of physical students, treatment after the first sprain (cold compress, cast or plaster bracing and medicine), visual analogue scale (VAS) during walking were assessed through ankle sprain questionnaire;Cumberland ankle instability tool (CAIT), Maryland foot score were applied to assess ankle function. Lateral ankle ligament injury was objectively assessed by musculoskeletal ultrasonography. The prevalence of acute ankle sprain(AAS) was 96.20% (531/552), and the incidence of AAS was 59.96% (622/1 104). The prevalence of chronic ankle joint instability(CAI) was 16.85% (93/552), and the incidence of CAI was 8.97% (99/1 104). In the four categories of sports, college student suffered from multiple sprains in performance majors group was 22.20% (14/63), including of aerobicsand dance performance. The incidence of AAS of ball sports was 8.60%(14/163). After the first sprain, most college students(94.4%) were received cold compression, about 60% of them went to hospital;however, only 44.7% students were received standard treatmens(cast or plaster), only 35.3% of them were received hard ankle orthosis. In 552 college students, 44 students were suffered from more than 4 times of ankle sprain, and the total incidence was 7.97% (44/552). Cumberland score was 26.6±2.4, Cumberland score of students sprained ankle joint more than 4 times was (29.2±1.1), suggested it was a risk factor for ankle joint instability. VAS of students sprained ankle joint more than 4 times was higher than that of less than 4 times(P<0.05), Maryland foot score was significantly lower than that of that of <4 times(P<0.05). Musculoskeletal ultrasonography measured the thickness of anterior tibiofibular ligament(ATFL) was (2.41±0.41) mm, and the thickness of calcaneofibular ligament(CFL) was (1.92±0.21) mm, and had no statistical difference(P>0.05). Ninty-four percent college students had at least once ankle sprain, ankle sprains were more common in erobics and ball sports. After the first sprain, the proportion of cast or plaster treatment was less than 50%. Sprained ankle joint more than 4 times is a risk factor, and musculoskeletal ultrasonography showed thickening of both ATFL and CFL, while no statstical difference.
