The aim of this research was to designate and compare the pacing profiles of the Turkish and Non-Turkish female and male athletes completed and ranked in the first tenth (n = 79) in the determined half-marathon road races held in Turkey. The pacings of the athletes were divided into 5 separate segments (0-5, 5-10, 10-15, 15-21.1 km) and calculated on the basis of their average transition speed (min:sec/km). The differences both between the pacing profiles of the Turkish and Non-Turkish athlete groups and between the successive segments within the groups were examined separately for women and men with the variance analysis for mixed patterns. According to the results, there was no statistical differences between the pacing profiles of both female and male Turkish and Non-Turkish athletes (p > 0.05). In addition, there was also no difference between the successive segments within the groups (p > 0.05). According to these results, it can be said that the pacing profiles of the Turkish and Non-Turkish elite athletes were similar and close to even pacing profile without a last sprint. Although it was not statistically significant, all the athletes had small decreases in their pacings in the first 15 km of the race. In the last 6.1 km segment, while small increases in the pacings of the Non-Turkish female athletes were observed, the pacings of the Turkish women athletes were more even with small decreases. Considering the whole race, it was seen that the athletes showed pacing profiles close to positive and reverse J-shaped pacing profile.

ObjectivesTo compare the mortality of Japanese athletes in the 1964 Tokyo Olympic Games with that of the Japanese population, and to elucidate factors associated with their mortality.MethodsWe obtained from the Japan Sport Association study subjects’ biographical information, information on lifestyles and medical data. Missing data were obtained from online databases. Standardised mortality ratio (SMR) was calculated to compare athletes’ mortality with the Japanese population. Cox proportional hazards model was applied to estimate the HR for each category of body mass index (BMI), smoking history and handgrip strength. This analysis was limited to male athletes due to the small number of female athletes.ResultsAmong 342 (283 men, 59 women) athletes, deaths were confirmed for 70 (64 men, 6 women) athletes between September 1964 and December 2017. Total person years was 15 974.8, and the SMR was 0.64 (95% CI 0.50 to 0.81). Multivariate analysis performed on 181 male athletes. Mortality was significantly higher for BMI≥25 kg/m2 than for 21–23 kg/m2 (HR: 3.03, 95% CI 1.01 to 9.07). We found no statistically significant associations between smoking history and mortality; the HR (95% CI) for occasional and daily smokers were 0.82 (0.26 to 2.57) and 1.30 (0.55 to 3.03) compared with never smokers. We also found no statistically significant associations between handgrip strength and mortality (P for trend: 0.51).ConclusionJapanese athletes in the 1964 Tokyo Olympic Games lived longer than the Japanese population. BMI≥25 kg/m2 was associated with higher mortality, but smoking history and handgrip strength were not associated with mortality.

The Relationship

There were two main purposes in the present study. The first was to identify the nature of the self-handicaps reported by elite female and male athletes (N = 245). School commitments and sport problems represented the most frequently cited impediments. Female athletes reported a significantly greater number of disruptions and had a greater tendency to report that sport problems, physical state/illness, and family/friend problems hindered their preparation. The second purpose was to determine whether cohesion would moderate the extent to which athletes would use self-handicapping strategies prior to competition. Hierarchical multiple regression revealed that cohesion was a moderator in the relationship between the trait of self-handicapping (Excuse Making) and the use of self-handicapping for both female and male elite athletes. Results of post hoc analyses indicated that athletes who were highly predisposed to self-handicap and who perceived their group as more cohesive, had a greater tendency to proactively perceive impediments to subsequent performance.

Aim. The article deals with the assessment of the thyroid status of athletes engaged in physical activity of varying intensity. Materials ant methods. 146 elite athletes involved in bobsleigh, biathlon, shooting and snowboarding participated in the study. We determined the serum concentration of thyroid stimulating hormone (TSH), free triiodothyronine (f.T3), free thyroxin (f.T4) and thyroid peroxidase antibodies (TPO-ab) with the COBAS e411 immunochemistry analyzer (Roche, Germany). The integral thyroid index ((f.T3 + f.T4)/TSH) was used for the assessment of the level of function of the thyroid proper. The conversion index of thyroxin to triiodothyronine (f.T4/ f.T3) was also studied. Results. 40 % of the bobsleigh athletes examined and 29 % of the snowboarders had high serum f.T3. The concentration of f.T4 in all examined athletes both male and female was within normal limits. Approximately 25 % of the male athletes examined had low II values. Among female athletes, 25 % of shooters and 33 % of bobsleigh athletes had low II values. In male biathletes and bobsleigh athletes, TPO-ab was 56 % higher than in shooters and snowboarders. In 43 % of bobsleigh athletes, 19 % of shooters, 10 % of biathletes and snowboarders, the content of TSH in males exceeded the reference intervals. Among females, TSH was high in 25 % of shooters and bobsleigh athletes. Conclusion. There were no statistically significant differences in the content of thyroid hormones in the compared sports groups, which can probably be explained by the activity of deiodinases at the local, intracellular level. At the same time, in a large number of respondents surveyed, the indicators of II and TPO-ab were outside the physiological norm.

Background: Asian representation in sport is increasing, yet there remains a lack of reference values for the Asian athlete's heart. Consequently, current guidelines for cardiovascular screening recommend using Caucasian athletes' norms to evaluate Asian athletes. This study aims to outline electrocardiographic and echocardiographic characteristics of the Asian athlete's heart using a Singaporean prospective registry of Southeast (SE) Asian athletes.Methods and Results: One hundred and fifty elite athletes, mean age of 26.1 ± 5.7 years (50% males, 88% Chinese), were evaluated using a questionnaire, 12-lead electrocardiogram (ECG) and transthoracic echocardiogram. All ECGs were analyzed using the 2017 International Recommendations. Echocardiographic data were presented by gender and sporting discipline. The prevalence of abnormal ECGs among SE Asian athletes was 6.7%—higher than reported figures for Caucasian athletes. The abnormal ECGs comprised mainly anterior T wave inversions (ATWI) beyond lead V2, predominantly in female athletes from mixed/endurance sport (9.3% prevalence amongst females). None had echocardiographic structural abnormalities. Male athletes had reduced global longitudinal strain compared to females (−18.7 ± 1.6 vs. −20.7 ± 2.1%, p < 0.001). Overall, SE Asian athletes had smaller left ventricular cavity sizes and wall thickness compared to non-Asian athletes.Conclusion: SE Asian athletes have higher abnormal ECG rates compared to Caucasian athletes, and also demonstrate structural differences that should be accounted for when interpreting their echocardiograms compared to athletes of other ethnicities.

Background. We aim to link fitness-related genotypes to the development of specific physical fitness phenotypes and a predisposition towards a specific sport category in Lithuanian elite athletes. Materials and methods. The study involved 193 athletes (152 male and 41 female) and 250 controls. The athletes were stratified into four groups: endurance, mixed sports, speed / power, and team sports. Genotypes of the athletes were identified according to the genetic polymorphisms: ACE (rs1799752), ACTN3 (rs1815739), PPARGC1A (rs8192678) and PPARA (rs4253778). One-way analysis of variance and logistic regression modelling were used for testing the genotype–phenotype association. Results. The frequency of ACE I allele was higher in athletes than in controls, although only male athletes showed a significant difference from male controls. The PPARA C allele was more common in the athlete group than in the general population of Lithuania. There were no significant ACTN3 and PPARGC1A SNP allele / genotype frequency differences between the athlete group and the controls. We have found that the ACTN3 RR genotype is associated with single muscular contraction power; the PPARGC1A Ser482Ser was associated with the muscle fat mass index; the PPARA CC and ACE II genotypes are associated with the muscle mass and single muscular contraction power. The effect of the gene variants was different for male and female athletes. Conclusions. The ACE II, PPARA CC, ACTN3 RR genotypes are related to the speed/power sports and the ACE DD, PPARA GG are related to the endurance sports in Lithuanian athletes. PPARGC1A Ser482Ser may be not critical but rather additive to endurance performance. Keywords: physical performance, ACE, ACTN3, PPARGC1A and PPARA genetic variants, sport category

ObjectiveThe increasing incidence of sports injury among athletes calls for systemic surveillance of injuries and illnesses in this field to develop preventive measures. The patterns of injuries and illnesses that occurred among Korean athletes during the 2018 Asian Games held in Indonesia were studied.MethodsWe recorded the occurrence of all injuries and illnesses reported to the chief medical officer, coordinated with the help of an instant social messaging application in real time.ResultsA total of 782 elite athletes participated in 46 sporting events. A total of 141 (18.03%) injuries were recorded, with 121 (15.47%) athletes suffering at least one injury. Out of 141 injuries 80 (56.74%) were in male athletes and 61 (43.26%) were in female athletes. The highest number of injuries was seen among sport climbing athletes (n=10, 71.43%), followed by sepak takraw. A total of 16 (11.35%) injuries were expected to prevent athletes from participation in competition/training. Most of the injuries occurred during training (46.10%), with lower lumbar spine being the most common part injured. A total of 209 (26.72%) illnesses were reported, with at least one illness in 170 (21.73%) athletes. The incidence among female athletes (26.90%) was comparable with that of male athletes (26.90%). Maximum illness rate was reported in table tennis (100%). The most common system involved was gastrointestinal (n=93, 44.49%), followed by respiratory (n=53, 25.36%). Environmental factors were causative in 111 athletes (53.11%) and infection in 79 (37.79%). Illnesses resulted in loss of at least 1 day among 30 (14.35%) athletes.ConclusionOverall 15.47% of athletes suffered at least one injury and 21.73% suffered at least one illness; the incidence of injury and illness varied depending on the type of sports.

Previous studies have suggested that media reify frames that subtly enforce sex differences in a manner that detracts from women athletes’ athleticism. This phenomenon is referred to as ambivalence. To analyze ambivalence, this study introduces a theoretically and empirically supported coding scheme that was used to conduct a quantitative frame analysis of 157 images featured in ESPN’s The Body Issue. These images were coded for frames that de-emphasize athleticism, sexualize athletes, or deny a sporting context. Results suggest that athlete sex is associated with de-emphasized athleticism and sexualized frames, and sport gender is associated with context frames. Results also support longitudinal trends in The Body Issue series, which suggest that the series has become more sexualized and removed from a sports context but has decreased the use of frames that de-emphasize athleticism. In general, The Body Issue continues to reinforce established media trends that trivialize female athletes, despite claiming to do the opposite.

To examine prevalence of verbal, physical, and sexual abuses in young elite athletes, a cross sectional questionnaire-based survey was conducted during the World Athletics under 20 World Championships. This questionnaire aimed at distinguishing between abuses perpetrated in the context of Athletics from those which were unrelated to Athletics. Four hundred and eighty athletes (52.3%, male) from North America, South America, Europe, Africa, Asia, and Oceania took part in the electronic anonymous survey. Outside Athletics setting, no gender difference was found for the prevalence of verbal, physical, and sexual abuses. However, 45 males (18% of the male population) and 34 females (15% of the female population) athletes reported sexual abuse. Asian athletes reported a slightly higher rate of sexual abuse; three quarters of them being non-touching abuses. Inside Athletics setting, no gender difference was found for the prevalence of verbal, physical, and non-touching sexual abuses. However, 58 males (23%) and 47 females (21%) reported verbal abuses. Thirty-one males (12%) and 20 females (9%) reported physical abuses, whereas 30 males (12%) and 17 females (7%) reported sexual abuses. Physical abuses were slightly more frequent in Asia and in Africa and less frequent in South America. Sexual abuses inside Athletics also differed over regions, and were unexpectedly twice more frequent than expected in Asia and slightly less frequent than expected in Europe. Friends and partners were identified as the more frequent (>50%) abusers outside or inside the Athletics settings, whereas outside Athletics and inside Athletics, coaches were identified as sexual abuse perpetrators in 8 and 25% of cases, respectively. The prevalence of verbal, physical, or sexual abuses is high but consistent with what has been reported in United Kingdom, Norway, Canada, and Sweden at national level in recreational or elite athletes. Sexual abuse, including touching or penetrative abuses, occurred significantly more often in male athletes when compared to female athletes. This finding invites healthcare and social workers, and policymakers to also consider the risk of sexual abuse of young male athletes in Athletics. These results also call for longitudinal studies on young elite athletes.

The chasse step is one of the most important footwork maneuvers used in table tennis. The purpose of this study was to investigate the lower limb kinematic differences of table tennis athletes of different genders when using the chasse step. The 3D VICON motion analysis system was used to capture related kinematics data. The main finding of this study was that the step times for male athletes (MA) were shorter in the backward phase (BP) and significantly longer in the forward phase (FP) than for female athletes (FA) during the chasse step. Compared with FA, knee external rotation for MA was larger during the BP. MA showed a smaller knee flexion range of motion (ROM) in the BP and larger knee extension ROM in the FP. Moreover, hip flexion and adduction for MA were significantly greater than for FA. In the FP, the internal rotational velocity of the hip joint was significantly greater. MA showed larger hip internal rotation ROM in the FP but smaller hip external rotation ROM in the BP. The differences between genders can help coaches personalize their training programs and improve the performance of both male and female table tennis athletes.
