Female trail running: a systematic scoping review Javier Espasa-Labrador, Øyvind Sandbakk, Álex Cebrián-Ponce, Alfredo Irurtia, Marta Carrasco-Marginet, et al. Frontiers in Sports and Active Living, 2026 Trail running's popularity among women is increasing, yet research addressing the unique physiological demands, performance factors, and injury patterns in this population remains limited. This scoping systematic review aimed to map the existing research landscape on female trail runners; synthesize current evidence across physiological, nutritional, injury, and performance domains; and identify critical knowledge gaps to guide future investigations. A systematic search was conducted across four major databases (EBSCO, PubMed, Scopus, Web of Science) up to December 2024. Eligible studies were original peer-reviewed articles reporting sex-specific data on female trail runners within the above domains. Methodological quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. Results from the 22 included studies (pooled sample ≈ 2,476 participants), predominantly published in the last decade, primarily focused on physiology and biomarkers (10 studies) and nutrition and body composition (6 studies), with fewer investigations into injuries (4 studies) or performance (3 studies). These studies indicated significant exercise-induced physiological stress and highlighted links between nutrition, body composition, and performance outcomes. However, a recurring limitation was the pervasive inconsistency in reporting participant characteristics, especially evident for key female-specific factors such as menstrual cycle status and hormonal contraceptive use, which were sparsely detailed. Furthermore, considerable heterogeneity in methodologies and the poor reporting of race characteristics and environmental conditions limited the synthesis of actionable insights. Most included studies (21 out of 22) demonstrated good methodological quality. In conclusion, while the research on female trail runners is growing, its practical application and the ability to draw robust conclusions are constrained by widespread reporting inconsistencies and a notable lack of depth in female-specific physiological data. Further progress in this field relies on the adoption of standardized reporting guidelines and a concerted effort to conduct robust, longitudinal investigations. Future studies should address hormonal influences, energy availability, effective training methodologies, and targeted injury prevention strategies tailored to female trail runners, ultimately to optimize their health, well-being, and athletic potential.
The Influence of Menstrual Cycle Phase on the Physiological and Perceptual Responses to Low-Intensity Continuous and High-Intensity Interval Sessions in Endurance Trained Women: The FENDURA Project Madison Y. Taylor, Heleen Docter, Klavs Madsen, Vilde Sophie Sogn Tjernes, Boye Welde, et al. European Journal of Sport Science, 2026 The influence of the menstrual cycle (MC) on the acute responses to endurance training remains unclear. This study aimed to investigate the effect of the MC on the physiological and perceptual responses to standardized low‐intenstiy continuous (LIT) and high‐intensity interval sessions (HIT). Naturally menstruating endurance‐trained women performed a standardized LIT ( n = 23) and/or HIT ( n = 23) session during the early‐follicular (EFP), ovulatory (OP), and mid‐luteal (MLP) phases of 2 MCs. Physiological (i.e., oxygen uptake (O 2 ), heart rate (HR), and blood lactate concentration (BLa)) and perceptual variables (i.e., rating of perceived exertion (RPE) and mood state) were measured. MC phases were determined using urinary ovulation kits and verified with serum hormone analysis. Non‐eumenorrheic MCs were excluded from analysis. During LIT and HIT, ventilation (VE) was higher in MLP than OP ( p < 0.001) and BLa was slightly higher in EFP than OP (LIT, p = 0.004, HIT, p = 0.001). During HIT, O 2 ( p = 0.025) and HR ( p = 0.036) were slightly higher during MLP than OP. RPE was slightly higher in EFP than OP in the LIT ( p = 0.036) and HIT ( p < 0.001). Vigor ( p < 0.001) and tension ( p = 0.036) were highest in EFP. No phase by time interactions were observed for any of the outcome variables throughout either session type ( p > 0.05). MC phase had a modest effect on several physiological and perceptual measures during LIT and HIT. However, the between‐phase differences were small and no clear trends emerged across variables to indicate that the overall demands of a LIT or HIT session would be substantially altered in any one particular MC phase.
The Development of a Valid and Reliable Questionnaire to Measure Menstrual Cycle and Hormonal Contraceptive Knowledge Among Athletes and Sports Performance Support Staff Brianna Larsen, Erica Greet, Stephen P. Bird, Karlee Quinn, Alice McNamara, et al. Scandinavian Journal of Medicine and Science in Sports, 2025 This study aimed to develop the first valid questionnaire to assess menstrual cycle (MC) and hormonal contraceptive (HC) knowledge in athletes and sports performance support staff. Questions were developed following a literature review and four knowledge domains were identified: (1) Normal MC Function, (2) MC Dysfunction, (3) Oral Contraceptive Pills, and (4) Other HCs. Experts ( n = 6) reviewed the initial questionnaire, followed by pre‐testing with athletes and support staff ( n = 19). Validity (item analysis, construct validity) and reliability (test–retest, internal consistency) were assessed following questionnaire administration to athletes and staff without MC education (“Low Knowledge” [LK] group; n = 156) and “High Knowledge” [HK] participants ( n = 30) with MC education. Most ( n = 122) LK participants completed the questionnaire twice to assess test–retest reliability. Expert review showed good agreement (> 80%) on item clarity and relevancy and pre‐testing indicated good content and face validity. The HK group scored significantly higher than LK participants across the questionnaire (43 ± 5 vs. 28 ± 10; p < 0.001; d = 1.48 [1.05, 1.90]) and all knowledge domains ( p < 0.05). High item discrimination parameters were found for all domains, indicating effective discrimination between respondents with different knowledge levels. Test–retest reliability was excellent (intra‐class correlation coefficient estimates from 0.93 [0.90, 0.95] to 0.98 [0.96, 0.99]), with all domains showing good‐to‐excellent reliability. Internal reliability (Cronbach's alpha) was considered acceptable (0.93 [0.92, 0.95]; α ≥ 0.7). This questionnaire delivers a valid and reliable tool to assess MC and HC knowledge amongst athletes and support staff and is recommended to guide and evaluate educational interventions to improve menstrual health literacy within sport.
Lower Prevalence of Disordered Eating Behaviours Among Norwegian Female Athletes Compared to Non-Athletes: A Cross-Sectional Survey Using the Eating Disorder Examination Questionnaire Mimmi M. S. Vedenpää, Edvard H. Sagelv, Monica Klungland Torstveit, Kristin Benjaminsen Borch, John Owen Osborne European Journal of Sport Science, 2025 The purpose of this study was to report and compare the prevalence of disordered eating behaviours (DEBs) among Norwegian female athletes of different competition levels and sport types, and non‐athletes of different physical activity levels. A total of 565 females (athletes: n = 189; non‐athletes: n = 376) completed the Eating Disorder Examination Questionnaire 6.0 (EDE‐Q). Athletes were categorised as recreational (n = 72), national (n = 94), or elite (n = 23), while non‐athlete females were sedentary (n = 111) or physically active but non‐competitive (exercisers: n = 265). A global EDE‐Q score of > 2.5 was considered as increased risk of an eating disorder. Data were modelled using linear or logistic regression, adjusted for body mass index (BMI), age category, and education level. Global EDE‐Q score was lower among recreational (mean [95% confidence interval]): (1.73 [1.31, 2.14]; p = 0.003; d = 0.50) and national‐level athletes (1.89 [1.52,2.26]; p = 0.024; d = 0.39) compared to exercisers (2.47 [2.19,2.75]), with recreational athletes also scoring lower than sedentary females (2.43 [2.09,2.78]; p = 0.022; d = 0.47). Leanness focused sports had higher restraint (p = 0.046; d = 0.30) and eating concern (p = 0.025; d = 0.35) subscale scores compared to non‐leanness focused sports. Recreational‐ or national‐level athletes scored on average lower DEB symptoms using EDE‐Q, compared to sedentary and physical‐active non‐athletes. No EDE‐Q difference was found between competition levels. Leanness focused sport athletes were more concerned about eating behaviours and had higher restraint than athletes from non‐leanness focused sports. These findings suggest that sport participation may be associated with lower or higher disordered eating symptoms, depending on competitive level and type of sport, highlighting the complexity of these relationships in physically active females.
Prevalence of Hormonal Contraceptive Use and Self-Reported Symptomatic Experiences Attributed to the Menstrual Cycle or Hormonal Contraceptive Use in Norwegian Women: The Effect of Training Categories and Age Groups - The FENDURA Project John Owen Osborne, Jonas H. Storvand, Tina P. Engseth, Guro S. Solli, Bente Morseth, et al. Scandinavian Journal of Medicine and Science in Sports, 2025 The aims of the current study were to (1) report the prevalence of hormonal contraceptive (HC) use among Norwegian women across different training categories and age groups; (2) compare the frequency and severity of cycle‐related symptoms across differing training categories and age groups; and (3) describe the bleeding pattern and prevalence of menstrual disorder/disturbances among non‐HC users. A sample of 2059 Norwegian women completed a survey reporting: weekly training volume; current HC usage, type, and reasons for use; cycle‐related symptom frequency and severity; and the prevalence of menstrual disorders/disturbances. Respondents were categorized by age (youth: 13–20; young adults: 21–30; older adults: 31–50 years) and training category (minimal: 0; low: < 5; moderate: 5–9; high: ≥ 9 h·week−1). Half (51.6%) of respondents reported current HC usage, predominantly long‐acting reversible contraception or combined oral contraceptives. Young adults had the highest prevalence of HC use (62.7%) compared to youth (48.4%) and older adults (43.8%), although no differences in usage were seen across training categories. HC users reported fewer and less severe cycle‐related symptoms compared to non‐users. A third (30.8%) of non‐HC users had experienced a menstrual disorder/disturbance, with no significant differences observed across training categories or age groups. In conclusion, HC use is widespread among Norwegian women, with no differences between training categories. This similar HC prevalence suggests that HC research conducted in female cohorts may be generalizable, independent of training category. However, attention should be paid to participants' age due to differences in HC use between age groups.
Running Economy After a Low- and High-Intensity Training Session in Naturally Menstruating Endurance-Trained Female Athletes: The FENDURA Project Heleen Docter, Madison Taylor, Anna Lena Müller, Jos J. de Koning, Øyvind B. Sandbakk, et al. Scandinavian Journal of Medicine and Science in Sports, 2025 The ability to maintain running economy is generally evaluated during a long continuous exercise bouts, and it is unclear whether the menstrual cycle phase acts as a confounder. The first aim of this study was to evaluate the ability to maintain running economy during typical 1‐h low‐ (LIT) and high‐intensity training (HIT) sessions in female athletes. The second aim was to investigate whether menstrual cycle phase affected the ability to maintain running economy. Naturally menstruating endurance‐trained females performed three LIT (n = 16) (45%–55% of the maximal velocity achieved during the maximal incremental test) and/or three HIT sessions (n = 17) (5 × 4 min at 80% of the maximal velocity achieved during the maximal incremental test) during three distinct menstrual cycle phases: early follicular, ovulatory, and mid luteal. Running economy was determined before and after each session. Running economy, expressed as energy cost (before: 1.34; after: 1.34 kcal/kg/km, p = 0.797) and oxygen cost (before: 272, after: 273 mL/kg/min, p = 0.348), was not significantly different before versus after the LIT session. Energy cost (before 1.33; after: 1.34 kcal/kg/km, p = 0.130) was not significantly different before versus after the HIT session, but oxygen cost (before: 269; after: 274 mL/kg/km, p < 0.003) was slightly higher after the session. Menstrual cycle phase did not confound the ability to maintain running economy. Running economy can be maintained during a typical 1‐h LIT session. The ability to maintain running economy during a typical HIT session depends on the expression used; energy cost was unaffected, while oxygen cost may be slightly increased after HIT sessions.
Sex Differences in Double Poling Performance: The Role of Upper-Body Strength and Endurance in Youth Elite Cross-Country Skiers and Biathletes Carl‐Maximilian Wagner, John Owen Osborne, Øyvind Sandbakk, Stephan Schiemann, Daniel Röhrs, et al. European Journal of Sport Science, 2025 The study aimed to investigate sex differences in double poling (DP) ergometer performance among youth elite cross‐country skiers and biathletes and determine if these sex differences may be explained by upper‐body strength and endurance capacities. Thirteen female and nine male youth elite cross‐country skiers and biathletes (age: 16.7 ± 1.7 years; VO2max: 60.7 ± 6.3 mL·kg−1 min−1), matched for relative performance, completed a test battery evaluating upper‐body strength and power along with various endurance parameters on a DP ergometer. Testing included one‐repetition maximum (1RM) in upper‐body exercises, maximal oxygen uptake (VO2max) running test, and DP ergometer incremental test to exhaustion and sprint tests to determine peak oxygen uptake (VO2peak‐DP), maximal lactate accumulation rate (vLamax), and power. Body mass and body composition were measured using bioelectrical impedance analysis. The findings demonstrated that the absolute differences in maximal strength, peak, and mean DP power outputs from both sprint and incremental tests to exhaustion (29%–38% difference), as well as maximal and peak oxygen uptake (29%–31%) between male and female athletes, were considerably reduced (2%–12%) following normalization to fat‐free mass (FFM). Correlations of absolute and FFM normalized VO2max, VO2peak‐DP with peak and mean power output from both sprint and incremental test to exhaustion during DP ergometry were significant (rxy = 0.69–0.87) and remained consistent after correction for sex (rxy‐z = 0.61–0.84). These findings suggest that sex performance differences are primarily attributable to absolute differences in maximal aerobic power, maximal strength, and FFM.
Hormonal Contraceptive Use and Self-Reported Menstrual Cycle-Related Symptom Frequency and Severity in Norwegian Team Handball Players of Different Competition Levels John O. Osborne, Erik P. Andersson, Sigurd Pedersen, Boye Welde, Svein Arne Pettersen, et al. International Journal of Sports Physiology and Performance, 2025 Purpose: To compare the frequency and severity of self-perceived negative symptoms associated with the menstrual cycle or hormonal-contraceptive (HC) cycle between (1) HC users and non–HC users and (2) different competition levels. An additional aim was to describe the rate and type of HC use and prevalence of potential menstrual-cycle disturbances in female team handball players. Methods: A total of 136 team handball players, competing at different levels (international, 48; national, 52; local/regional, 36), completed a cross-sectional survey regarding self-reported negative cycle-related symptom frequency and severity, perceived influence on training/competition performance, menstrual function, and current and/or past HC use. Results: Although most players regularly experienced negative cycle-related symptoms, non–HC users reported more frequent and severe cramps (P = .001 to .026), as well as a higher occurrence of fatigue and skin problems (P = .019 to .045), compared with HC users. Negative symptoms such as fatigue were more common and severe for local/regional-level players compared with players at higher (international) competition levels (P = .006–.046). Half (47%) of the players currently used HC, primarily long-acting reversible contraceptives (52%), as well as the combined oral (33%) or progestin-only pill (14%). Notably, only 2% of players altered their training in response to negative cycle-related symptoms, despite 41% perceiving that these symptoms interfered with training quality and athletic performance. Conclusions: Negative cycle-related symptoms are common among team handball players, regardless of HC use, and are perceived by many players to adversely influence their athletic performance.
