The impact of exercise-specific face masks (ESFMs) in aerobically fit individuals on physiological, perceptual, respiratory, and performance responses remains unclear. How ESFMs mitigate exercise-induced bronchoconstriction (EIB) is also unknown. Thus, this study aimed to determine how an ESFM altered within-exercise physiological, perceptual, respiratory, and performance responses to graded treadmill exercise. Twenty-four individuals (11 females) completed a discontinuous graded exercise test on a treadmill under two conditions (ESFM and unmasked). Physiological, respiratory function, and perceptual measures were assessed. Performance was determined by time to exhaustion. Statistical analyses included linear mixed-effects modeling, repeated measures analysis of variance, and pairwise comparisons using an alpha value of 0.05. ESFM use significantly impaired performance (median = −150.5 s) and decreased arterial oxygen saturation at maximal intensity (mean = −3.7%). Perceptions of air hunger and work of breathing were elevated across submaximal and maximal intensities. Perceived exertion and breathing discomfort were significantly elevated submaximally but not maximally. Spirometry measures were not significantly different at termination but were significantly improved at submaximal intensities in participants with and without EIB. ESFM use in fit individuals increased perceptual discomfort, impaired performance, and augmented arterial desaturation. Respiratory function improvements were observed but were accompanied by adverse perceptual sensations. Despite this, performance impairments may limit the real-world utility of ESFMs for athletes.

The purpose of this study was twofold: first, to identify who engaged with the Keeping Girls in Sport e-learning program and, second, to evaluate coach and activity leaders’ perceptions of the program and their perceived learnings gained from completing the program. An explanatory sequential mixed-method design was adopted. First, an online survey was distributed to all individuals who had participated in the program. In total, 511 (33% response rate) completed the survey. Quantitative survey data were analysed using descriptive statistics. Subsequently, interviews were conducted with 20 survey respondents. A realist logic of analysis was applied to the qualitative data, and context–mechanism–outcome configurations were formed. Overall, survey findings indicated that most participants identified as women (56%), coaches (69%), and were between 40 and 49 years of age (37%). In general, participants had positive perceptions of the program. Participants perceived that the accessibility and flexibility of the program increased opportunities to engage with content and, thus, their learning. They described improvements in knowledge and perspective regarding working with female athletes. This increase in knowledge provided participants with confidence to establish trusting and positive relationships with others, specifically parents. Nevertheless, participants highlighted a need for more tailored but also more expansive programs.
