Context:Sports nutrition experts recommend that team-sport athletes participating in intermittent high-intensity exercise for ≥1 hr consume 1–4 g carbohydrate/kg 1–4 hr before, 30–60 g carbohydrate/hr during, and 1–1.2 g carbohydrate/kg/hr and 20–25 g protein as soon as possible after exercise. The study objective was to compare observed vs. recommended macronutrient intake of competitive athletes under free-living conditions.Methods:The dietary intake of 29 skill/team-sport athletes (14–19 y; 22 male, 7 female) was observed at a sports training facility by trained registered dietitians for one 24-hr period. Dietitians accompanied subjects to the cafeteria and field/court to record their food and fluid intake during meals and practices/competitions. Other dietary intake within the 24-hr period (e.g., snacks during class) was accounted for by having the subject take a picture of the food/fluid and completing a log.Results:For male and female athletes, respectively, the mean ± SD (and percent of athletes meeting recommended) macronutrient intake around exercise was 1.4 ± 0.6 (73%) and 1.4 ± 1.0 (57%) g carbohydrate/kg in the 4 hr before exercise, 21.1 ± 17.2 (18%) and 18.6 ± 13.2 (29%) g carbohydrate/hrr during exercise, 1.4 ± 1.1 (68%) and 0.9 ± 1.0 (43%) g carbohydrate/kg and 45.2 ± 36.9 (73%) and 18.0 ± 21.2 (43%) g protein in the 1 hr after exercise.Conclusion:The male athletes’ carbohydrate and protein intake more closely approximated recommendations overall than that of the female athletes. The most common shortfall was carbohydrate intake during exercise, as only 18% of male and 29% of female athletes consumed 30–60 g carbohydrate/hr during practice/competition.

Analyze Data

The purpose of this investigation was to assess nutrition knowledge, opinions, and practices of coaches and trainers at a Division I university. Participants (n = 53) completed questionnaires regarding nutrition knowledge, opinions, and practices. Descriptive statistics and analysis of variance were used to analyze data. Overall, participants responded correctly to 67% of nutrition knowledge questions. Participants who coached/trained female athletes tended to score better than respondents who coached/trained male athletes. Strength and conditioning coaches and participants with greater than 15 years of experience scored higher than other participants. Nutrition opinions/practices responses revealed that nutritional supplements were provided for all but 6% of participants’ athletes. Participants rated body weight as more important than body composition to athletes’ performances. Over 30% of participants perceived at least one case of disordered eating within the past year. Some participants (53%) felt that athletes may consume more nutritious meals on team-sponsored trips if given larger food allowances. Thirty percent of participants reported dietitians were available to them; the same percentage reported utilizing dietitians. Coaches and trainers are knowledgeable about some appropriate nutritional recommendations, but registered dietitians or qualified sports nutrition professionals may complement the nutrition-related education and counseling of athletes (23).

Background: Sudden deaths in young competitive athletes are highly visible and tragic events, which receive much public visibility. However, little is known regarding the specific impact of gender on these events. Methods and Results: The U.S. National Registry of Sudden Death in Athletes was accessed to identify the causes, frequency and epidemiology of sudden deaths in U.S. competitive athletes by gender. A total of 2,408 deaths (2155 male; 253 female) were identified in athletes engaged in 41 diverse organized sports from 1980 to 2011. Most sudden deaths occurred with physical exertion during competition/training (66%), and were predominantly due to cardiovascular disease (54%). In high school and college athletes, accounting for participation rates, the ratio of male to female deaths was 5.4:1. Males were somewhat older than females (19±6 vs. 17.8±6; P=0.003), and were more commonly black (30% vs. 17%; P<0.001). Of the male athletes, the highest rate of cardiovascular sudden death was in blacks (65% vs. 49% in whites; P<0.001). The most frequent sports were football (n=725) and basketball (n=437) in males, and basketball (n=47) and cross country/track (n=41) in females. Most common cardiovascular cause of death was hypertrophic cardiomyopathy (HCM), which accounted for a greater proportion of confirmed cardiovascular deaths in males (47%) vs. females (14%; P<0.001); a 19:1 male:female ratio in high school and college athletes. In contrast, females experienced greater frequency of death due to congenital coronary artery anomalies (30% vs. 14%; P<0.001), arrhythmogenic right ventricular dysplasia (12% vs. 4%; P=0.018), and long-QT syndrome (7% vs. 1%; P<0.001). Blunt trauma, including commotio cordis, occurred more frequently in males (24% vs. 15% in females; P=0.001). Conclusions: Female athletes have a 5-fold lower risk for sudden death, compared to males, and were almost 20-times less likely to die of HCM. Black males had the highest rate of sudden death due to cardiovascular disease, with HCM most common.

Eligibility Criteria

Field-based team sports present large energetic demands given their intermittent high-intensity nature. Current evidence suggests that the dietary intake of female athletes may be insufficient to meet such demands, resulting in negative consequences for athletic performance and health. The primary aim of this review was to therefore assess the adequacy of dietary intake of female field-based team sport athletes when compared to dietary recommendations. A systematic search of databases, including PubMed, Web of Science, SPORTDiscus, and OpenGrey, was performed from the earliest record available until July 2020, obtaining an initial total of 2588 articles. To be included within the final review, articles were required to provide a quantitative assessment of baseline dietary intake specific to the target population. A total of 20 studies (n = 462) met the full eligibility criteria. A majority reported that the dietary intake of female field-based team sport athletes was insufficient in overall energy (2064 ± 309 kcal·day−1), carbohydrate (4.3 ± 1.2 g·kg·day−1), and iron intake (13.6 ± 6.2 mg·day−1) when compared to recommendations. Future research is required to establish why female team sport athletes consistently demonstrate deficient dietary practices, and to explore the potential negative consequences of this.

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.

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.

Energy needs of female team-sport athletes are poorly understood with no evidence highlighting differences present between scheduled activities. The purpose of this study was to examine the difference in energy expenditure between NCAA Division II female basketball (BBALL) and lacrosse (LAX) athletes during different scheduled team activities. Female BBALL (n = 13; 19.8 ± 1.3 yrs; 173.9 ± 13.6 cm; 74.6 ± 9.1kg; 27.1 ± 3.2%fat) and LAX (n = 20; 20.4 ± 1.8yrs; 168.4 ± 6.6cm; 68.8 ± 8.9kg; 27.9 ± 3.1%fat) athletes were outfitted with heart rate and activity monitors during four consecutive days on five different occasions (20 days total) across an entire academic year to assess differences in total daily activity energy expenditure (TDEE), activity energy expenditure (AEE), and physical activity level (PAL). Data were categorized by type of scheduled daily activities: Practice, Game, Conditioning, or Off. Independent of day type, TDEE, AEE, and PAL levels were greater (p < 0.05) in BBALL athletes. For each sport, TDEE, AEE, and PAL were significantly different (p < 0.05) between classified activity days. BBALL and LAX athletes experienced higher values on game days for TDEE, AEE, and PAL, with the lowest values experienced on off days. In conclusion, calculated levels of TDEE, AEE, and PAL in female collegiate BBALL and LAX athletes were determined to be different, irrespective of the scheduled activity.

Concussion Management

This research applied muted group theory to investigate female and male athletes’ experiences with not reporting concussions sustained during athletic competition. Using snowball-sampling techniques, a total of 365 women and 247 men completed an online open-ended questionnaire about their reasons for not reporting a concussion. Results indicated that male athletes were more likely to continue to play through and not report a concussion than female athletes. Participants also indicated that they did not report concussions due to (a) perceived lack of resources, (b) perceived lack of severity, (c) conformance to sport cultural norms, which was comprised of two subthemes: adherence to the pain principle and team allegiance. The results suggest that efforts to address concussion management in sport need to focus on the communicative and structural elements that privilege hegemonic masculinity and playing through pain, as they contribute to muting athletes in advocating for their health.

Female Coaches

Historically, the world of sport is considered a masculine domain characterized by power, aggression, and physical contact (Hall, 1996). The exclusionary elements of the male culture of sport have created gender inequities in participation (Birrell & Theberge, 1994), and a gendered perception of male and female coaches (Frankl & Babitt, 1998; Weinberg, Reveles, & Jackson, 1984). The purpose of this study was to examine the perceptions of male and female collegiate athletes of a hypothetical male and female coach, and to determine if female coaches are more accepted compared to Weinberg et al.’s study investigating male and female athletes’ perceptions of a hypothetical coach. The Attitudinal Questionnaire (Weinberg, Reveles, & Jackson, 1984) was utilized to determine athletes’ attitudes about a hypothetical coach. A 2 × 2 MANOVA indicated a significant interaction between the gender of a hypothetical head coach and the gender of an athlete, and a significant main effect for gender. Univariate ANOVA results indicate that males and females differed in their attitudes and perceptions of both a hypothetical male and female head coach. The female athletes, compared to male athletes, were more likely to be accepting of coaches regardless of the coaches’ gender. Furthermore, male athletes were less accepting of female coaches. In addition, when comparing the means of the current study to Weinberg et al.’s (1984) study, results indicate that female coaches were not more accepted than in 1984.

Abstract Introduction Mental fitness is increasingly considered key to an athlete’s competitive arsenal. Its active ingredients include cognitive fitness factors, such as impulse control, and recovery factors, such as sleep, which may differ between male and female athletes. Our study investigated: 1) gender differences in cognitive fitness; and 2) the associations of gender and cognitive fitness with sleep and mental health in competitive athletes during the COVID-19 lockdown. Methods 84 athletes competing at levels from regional/state to international (42F, mean age=23.2) completed a questionnaire battery containing validated measures of: a) depression, anxiety, and stress; b) sleep (Total Sleep Time, Sleep Latency, mid-sleep time on training- and competition-free days); and c) self-control, intolerance of uncertainty, and impulsivity (representing cognitive fitness constructs). Results Female athletes reported significantly higher depression, anxiety, and stress, a later mid-sleep time on free days, lower self-control, higher intolerance of uncertainty, and higher positive urgency impulsivity compared with male athletes. Self-control was negatively associated, and intolerance of uncertainty was positively associated, with depression, anxiety, and mid-sleep time on free days. Discussion Female athletes in our sample reported poorer mental health and cognitive fitness, and later sleeping times on free days. Greater cognitive fitness was associated with better mental health, independent of gender. Overall, these findings are consistent with prior work in community samples. Future work should examine the source(s) of these gender differences. If replicated, our findings would suggest a need to develop interventions aimed at improving athlete well-being, potentially with a particular focus on female athletes.

Objective Training monitoring has become an integral component of total athlete training. Systematically monitoring the physiological and biochemical variables related to performance helps coaches and athletes to measure the effectiveness of their training programs and decide how to revise or update those programs, especially in swimming training. The key purpose of this study is to evaluate the physical function characteristics during preparation season and stress response during competition training sessions in 2017, and provides the helpful data for scientific training for the implementation of the preparation process. Methods During the preparation period, the National Swimming Team athletes were planed to screen and test the physical function characteristics. There are 39 male athletes and 37 female athletes to participate in the study. Body composition was assessed with dual energy X-ray (DXA). Anthropometric characteristics were assessed using Anthroscan 3D VITUS body scanner, and pulmonary function test using CHEST portable lung function meter(HI-101). During the competition period, the training load monitoring targets were 2 elite players who participated in XVII World Aquatics Championship in Budapest-2017 and the National Games 2017. The monitoring methods mainly included: blood tests (including Hb, CK, BU, testosterone, cortisol and ferritin etc.) were used to monitor the athlete's fitness functional status, and the Z-score method was used to express the index changes of two athletes; blood lactate was used to monitor the training load of athletes, and urine indexes were used to monitor body fluid balance and fatigue. Results 1. During the preparation period, the weight of male athletes is 78.4±8.2kg, the percentage of body fat is 15.9±2.8%, the weight of female athletes is 64.8±6.6kg, and the percentage of body fat is 24.2±3.5%. The vital capacity(VC) was 6.65±0.87 L for males and 4.86±0.69 L for females, the value of forced vital capacity(FVC) was 4.29±1.33 L for males and 3.43±0.96 L for females, and the mean value of ventilation per minute was 148.1±23.12 L for males and 110.4 ± 19.67 L for females. 2. During the competition preparation period, Z score was used to express the blood indicators of two athletes, before the XVII World Aquatics Championship in Budapest-2017, the Z score of Hb, T, T/C ratio and ferritin were (-0.5, 0, -0.4, 1.1) and (-0.8, -0.1, -1.0, 0), respectively. Before the competition of the National Games, the Z scores were (1.0, 0.3, 0.7, 0.6) and (1.4, 1.0, 0.1, -0.6) respectively. 3. Training load monitoring was carried out using the blood lactate control test, as the training load increased, the athletes' performance improved and the lactate level increased slightly. 4. The urine indicator test is used to observe the athlete's dehydration and recovery. On the second morning after the intensive training day, both athletes were negative for urine protein and with normal urine specific gravity. Conclusions 1. The screen and tests about the physical function characteristics of swimming athletes during preparation period is useful to develop a personalized training plan; 2. Z-score is easy and feasible for the elite swimmers to monitoring physical fitness capabilities, and higher Z-score is related with better athletic performance; 3. Blood lactate control test can be used for the training intensity monitoring of swimmers, athletes show higher levels of lactic acid metabolism and higher athletic performance before the competition.
