This study aimed to contrast the impacts of an exercise intervention using either bounce drop jump (DJ; fast stretch-shortening cycle exercise) or countermovement jump (CMJ; slow stretch-shortening cycle exercise) on measures of physical fitness in young females. A total of 23 young females (age: 19.7 ± 1.0 years, height: 159.8 ± 4.2 cm, body mass: 54.3 ± 14.3 kg) were randomly assigned to either DJ (n = 12) or CMJ (n = 11) training, which spanned 6 weeks. Pre- and posttraining assessments were conducted for 10 m and 30 m linear sprints, change-of-direction speed, CMJ, DJ (jump height, contact time, and reactive strength index), standing long jump, triple-hop distance, and isometric strength. Apart from the variance in jump technique, both interventions were standardized in terms of total repetitions, intensity, and surface type. No significant Group × Time effect was observed in any dependent variables (all p > .05). A significant time effect was observed in 10 m (p < .001, effect size [ES] = 0.70) and 30 m (p < .001, ES = 0.79) linear sprint, CMJ height (p = .012, ES = 0.34), DJ contact time (p = .012, ES = 0.34), and triple-hop distance (p = .006, ES = 0.38). Both DJ and CMJ training interventions led to comparable improvements in linear sprints, CMJ height, DJ contact time, and triple-hop distance. These findings suggest that the duration of ground contact during intervention exercises (i.e., fast vs. slow stretch-shortening cycle) did not significantly influence initial (6 weeks) physical fitness adaptations in young females. However, extending these results to highly trained groups (e.g., athletes) warrants further investigation.

Risk of Low Energy Availability in New Zealand National Team and U20 Female Football Representatives
Isabella Coombes and Claire E. Badenhorst
Background: Rates of low energy availability (LEA) in female footballers range from 12% to 66%, studies are limited, and no research has yet looked at the prevalence of LEA in a cohort of international players. Due to the negative consequences of LEA, more research is needed for a thorough investigation into prevalence rates and the associated risk factors of LEA within international environments. Methods: Twenty-two members of the New Zealand under 20 (U20) and National Women’s football teams (20.8 ± 3.5 years) participated in this study. Participants completed an online questionnaire composed of five independent validated surveys to assess LEA risk (Low Energy Availability in Females Questionnaire), eating disorder risk (Eating Disorder Examination Questionnaire), sleep quality (Athlete Sleep Score Questionnaire), nutrition knowledge, (Abridged Sport Nutrition Questionnaire), and mood (Profile of Mood States Questionnaire). Results: 59.1% (n = 13) of participants were identified as being at risk of problematic LEA. Players reporting menstrual disturbances (amenorrhea or oligomenorrhea) were 2.25 times more likely to be at risk of LEA than those who did not report a menstrual disturbance. Menstrual status (R = −.46, p = .030) and Profile of Mood States Questionnaire (r = −.46, p = .032) were significantly and positively associated with risk of LEA (R = −.46, p = .030). Conclusions: A significant proportion (59.1%) of players in the New Zealand national and U20 female football team are at risk of LEA. The positive and predictive relationship observed between mood disturbances, menstrual status, and risk of LEA suggests that regular monitoring of mood and menstrual cycle health may be used for the early identification of problematic LEA in national-level female footballers in New Zealand.

Motivations and Barriers to Leisure-Time Physical Activity Among Rural Women of Gipuzkoa
Olaia Eizagirre-Sagastibeltza, Uxue Fernandez-Lasa, and Oidui Usabiaga
Women do less physical activity than men, and physical inactivity among women is higher during active years (ages 18–65). In addition, women residing in rural areas do less physical activity than those living in urban areas. The aim of this study was to analyze the habits, motivations, and barriers linked to leisure-time physical activity (LTPA) among women of rural areas of Gipuzkoa (Basque Country, Spain), from a socioecological and feminist approach. Two hundred and ninety-six rural women from Gipuzkoa, aged 18–65 (41.1 ± 11.2), answered the Gipuzkoa Women’s Physical Activity Questionnaire. Pearson’s chi-square test and independent samples test were used to compare the responses between the active and inactive groups. 62.8% of the participants were active, while 37.2% were inactive. In terms of intrapersonal factors, being fit was the main motivation for doing LTPA, and lack of time was the main barrier. Among the interpersonal factors, the main motivation was being in contact with friends and people they enjoyed, and the main barrier was not having someone to go with. Motherhood was not an impediment to do LTPA, and the support received from partners, family, and friends made it easier for the subjects to remain active. The influence of the physical environment and sociocultural factors was small, with the COVID-19 confinement being the main reason motivating LTPA, and the weather the main barrier. There are multiple factors that affect LTPA among rural women, and it is important to consider this collective’s diversity in order to promote healthy lifestyle habits.
Female Physiology–Endocrinology: Education Is Lacking and Innovation Is Needed!
Anthony C. Hackney and Kirsty J. Elliott-Sale
Throughout their lifespans, women undergo unique endocrinological changes relative to their reproductive hormones. The influence of how the female sex steroid hormones have nonreproductive actions is a trending topic of great interest in the exercise–sports sciences, especially among women of reproductive age. Herein, we present several key points on our perspective for moving the study of this topic forward in the future. These are (a) encouraging researchers to pursue high-quality research on female physiology–endocrinology in the exercise–sports science setting, (b) the need for exercise–sports science educational curriculums at the university level to embrace the study of female physiology–endocrinology area, and (c) the need for innovation in the study of this topic. As such, we propose using research design models involving supraphysiological hormonal states in vivo, that is, pregnancy and in vitro fertilization treatment, to gain new insights on sex steroid hormonal actions in women. Herein, we provide the rationale for our recommendations as well as a brief physiological overview of these clinical states. We acknowledge, exercise sports sciences need more studies on women! But there is a need to “think outside the box” on this topic, and we encourage researchers to be unconventional, be bold, think creatively, and contemplate whether these supraphysiological hormonal states might give them insightful information on female physiology and ovarian sex steroid hormones actions.
Girls, Women, and Female Athletes in Sport Psychology: A Decade-Long Review of the Literature
Alex Murata, Cailie S. McGuire, Madison Robertson, Mia KurtzFavero, Jennifer T. Coletti, Philip B. Simpson, Ella Pierone, Luc J. Martin, and Jean Côté
The underrepresentation of female research participants, women, and girls has been highlighted as an issue of concern within a variety of research areas and disciplines across academia. More specifically, this lack of visibility has contributed to widening knowledge gaps regarding these populations while also perpetuating and strengthening existing inequities. Given these concerns, the purpose of this review was to explore whether similar imbalances could exist within the sport psychology literature and, if so, what future research projects might be completed to rectify these issues. To do so, all articles (n = 3,005) published between the years of 2011 and 2021 in five journals of sport psychology were assessed. Following an analysis of the relevant studies collected, it was found that more articles including all boys, men, and male athletes (n = 343) were published within this time frame compared with articles including exclusively girls, women, and female athletes (n = 155). Additionally, it also appeared that research working with girls, women, and female athletes was lacking: (a) in recreational sport, (b) at both young and older ages, and (c) within team sport contexts. Further, most of the studies assessed often conflated participant sex- and gender-descriptive terminology. As such, it is highly encouraged that researchers in sport psychology make greater strides to conduct purposeful and targeted research focusing on girls, women, and female athlete participants and their specific issues over the coming years.

Dance in Black and White: Examining the Stereotypes of Black and White Ballerinas and Hip-Hop Dancers
Sydney Klein, Colin A. Zestcott, and Alaina Brenick
Throughout the course of ballet dance history, White ballerinas have maintained the spotlight—subsequently leaving limited representation of Black ballerinas. However, other forms of dance, such as hip-hop, may yield greater representation of Black dancers due to hip-hop’s origins during the Harlem Renaissance. The current work examined if perceivers stereotype ballet and hip-hop as dance forms more suited for White or Black dancers, respectively. Two hundred sixty-eight online participants completed explicit and implicit (implicit association test) stereotyping measures examining endorsement of the ballet = White and hip-hop = Black stereotypes. In step with predictions, results showed that individuals were more likely to explicitly and implicitly endorse White women as ballerinas and Black women as hip-hop dancers. In addition, participants with ballet and hip-hop dance experience were less likely to endorse the stereotype that ballet dancers are White and hip-hop dancers are Black. Moreover, less stereotype endorsement also predicted greater likelihood of seeing a ballet or hip-hop performance in the future. These findings suggest that perceivers hold expectations about racial identities of dancers in ballet and hip-hop dance. Future directions regarding the role of race and stereotyping in the world of dance and the performing arts are discussed.
“Invisible Sportswomen 2.0”—Digging Deeper Into Gender Bias in Sport and Exercise Science Research: Author Gender, Editorial Board Gender, and Research Quality
Emma S. Cowley, Sam R. Moore, Alyssa A. Olenick, and Kelly L. McNulty
Objectives: Women are underrepresented as participants in sport and exercise science research, and most of the research is of low quality. To reduce the gender data gap, it is imperative to understand where this bias originates. The purpose of this study was (a) to evaluate the proportion of first and last author, and editorial board gender, and (b) to explore the association between gender and quality of female-specific research methods. Method: Studies exclusively investigating female participants (2014–2021) were extracted from a larger data set and updated through 2022. First author, last author, and editorial board gender were determined (e.g., from gender pronouns on institutional profiles, Google Scholar, and ResearchGate). Where applicable, study methodology was assessed by giving each study a quality score (0–1) based on key methodological considerations. Descriptive statistics were used to describe author and editorial board gender frequencies. Analyses of variance were used to investigate the associations between gender and female-specific methodological quality. Results: Within 438 female-only studies, data revealed a greater proportion of women first authors (55%) and men last authors (62%). There was an association between women authors (first, last, and both) and higher quality score for female-specific methods across all journals (p = .00–.04). The two lowest-ranked journals for quality score demonstrated worse gender parity within their editorial board (0%–12% women). Conclusions: The results from this study show that most female-only studies were senior authored by men. However, studies led by women had higher quality of female-specific methods. Future research is needed to explore gender distribution of senior academics.
