Most studies that have shown the positive effects of caffeine supplementation on sports performance have been carried out on men. However, the differences between sexes are evident in terms of body size, body composition, and hormonal functioning, which might cause different outcomes on performance for the same dosage of caffeine intake in men vs. women. The main aim of this systematic review was to analyze and compare the effects of caffeine intake between men and women on sports performance to provide a source of knowledge to sports practitioners and coaches, especially for those working with women athletes, on the use of caffeine as an ergogenic aid. A structured search was carried out following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines in the Web of Science, Cochrane Library, and Scopus databases until 28 July 2019. The search included studies in which the effects of caffeine supplementation on athletic performance were compared between sexes and to an identical placebo situation (dose, duration and timing). No filters were applied for participants’ physical fitness level or age. A total of 254 articles were obtained in the initial search. When applying the inclusion and exclusion criteria, the final sample was 10 articles. The systematic review concluded that four investigations (100% of the number of investigations on this topic) had not found differences between sexes in terms of caffeine supplementation on aerobic performance and 3/3 (100%) on the fatigue index. However, four out of seven articles (57.1%) showed that the ergogenicity of caffeine for anaerobic performance was higher in men than women. In particular, it seems that men are able to produce more power, greater total weight lifted and more speed with the same dose of caffeine than women. In summary, caffeine supplementation produced a similar ergogenic benefit for aerobic performance and the fatigue index in men and women athletes. Nevertheless, the effects of caffeine to produce more power, total weight lifted and to improve sprint performance with respect to a placebo was higher in men than women athletes despite the same dose of caffeine being administered. Thus, the ergogenic effect of acute caffeine intake on anaerobic performance might be higher in men than in women.

Aim. The aim of this study was to assess the vitamin status of athletes involved in various sports before important competitions. Materials and Methods. Athletes (n = 176) from six sports (сross-country skiing, biathlon, cycling, track-and-field, taekwondo, basketball) living in the territory of the Komi Republic were examined. Blood sampling was performed from the cubital vein 5–7 days before important competitions. Results. The results of this study showed widespread inadequate levels of some of the vitamins in athletes. The greatest number of people with hypovitaminosis (especially vitamins B1 and E) was among cross-country skiers, biathletes and taekwondo athletes. In general, the situation was similar for men and women. Comparative ana­lysis of the vitamin status in athletes and people from this area (not athletes) showed that women-athletes had a generally higher incidence of deficiency than nonathletic women, and men-athletes had a similar vitamin status to nonathletic men. Conclusion. The results of this study showed that highly skilled athletes, regardless of the sport, were characterized by a high risk of vitamin deficiency. It is necessary to pay attention to the vitamin status of athletes, so as not to put at risk their health and physical performance.

In contrast to the sex-segregated model that dominates sport and contributes to its tradition of hegemonic masculinity, collegiate track and field typically follows a sex-integrated structure whereby men and women train, travel, and compete together. In this article, the authors examined how six collegiate male track-and-field athletes who are part of a sex-integrated team navigate gendered norms and hierarchies with a particular focus on their understandings of gender(ed) performance and abilities. Grounded in a feminist poststructuralist framework, the authors’ analysis found that although the participants were accepting of a sex-integrated training environment and challenged some gender stereotypes and instances of sexism, they simultaneously reified these same gender stereotypes by characterizing women athletes as “emotional” or “less competitive” and advocated individual solutions to institutional sexism.

This study analyzed the frequency with which the 2018 Pyeongchang Winter Olympic broadcasts featured men and women athletes. To understand these portrayals, all 557 hr and 15 min of National Broadcasting Company’s (NBC) 2018 Winter Olympic telecasts were recorded. This recorded content included the 62 hr and 30 min of NBC’s primetime program and, for the first time, all of the remaining non-NBC primetime coverage on NBC’s other networks. Women athletes received the majority of the clock time on the NBC primetime broadcast; however, men received significantly more clock time on the remaining Olympic telecasts. Additionally, for both sets of broadcasts, differences were found between the amount of coverage for men and women athletes by sport. Through the lens of agenda-setting theory, potential reasons and ramifications for the different trends of coverage by broadcast are discussed.

Abstract Background Caffeine supplementation (CAFF) has an established ergogenic effect on physical performance and the psychological response to exercise. However, few studies have compared the response to CAFF intake among athletes of different competition level. This study compares the acute effects of CAFF on anaerobic performance, mood and perceived effort in elite and moderately-trained recreational athletes. Methods Participants for this randomized, controlled, crossover study were 8 elite athletes (in the senior boxing national team) and 10 trained-recreational athletes. Under two experimental conditions, CAFF supplementation (6 mg/kg) or placebo (PLAC), the athletes completed a Wingate test. Subjective exertion during the test was recorded as the rating of perceived exertion (RPE) both at the general level (RPEgeneral) and at the levels muscular (RPEmuscular) and cardiorespiratory (RPEcardio). Before the Wingate test, participants completed the questionnaires Profiles of Moods States (POMS) and Subjective Vitality Scale (SVS). Results In response to CAFF intake, improvements were noted in Wpeak (11.22 ± 0.65 vs 10.70 ± 0.84; p = 0.003; $$ {\eta}_p^2 $$ηp2=0.44), Wavg (8.75 ± 0.55 vs 8.41 0.46; p = 0.001; $$ {\eta}_p^2 $$ηp2 =0.53) and time taken to reach Wpeak (7.56 ± 1.58 vs 9.11 ± 1.53; p <  0.001; $$ {\eta}_p^2 $$ηp2 =0.57) both in the elite and trained-recreational athletes. However, only the elite athletes showed significant increases in tension (+ 325%), vigor (+ 31%) and SVS (+ 28%) scores after the intake of CAFF compared to levels recorded under the condition PLAC (p <  0.05). Similarly, levels of vigor after consuming CAFF were significantly higher in the elite than the trained-recreational athletes (+ 5.8%). Conclusions CAFF supplementation improved anaerobic performance in both the elite and recreational athletes. However, the ergogenic effect of CAFF on several mood dimensions and subjective vitality was greater in the elite athletes.
