Elite female Australian Rules footballers report poorer mental health relative to elite male players, especially when their sleep is disrupted, Monash University-led research has found.
All elite athletes face a unique set of stressors on a daily basis, which make them vulnerable to sleep disruption and associated mental health symptoms. The results of this study strengthen the calls for more support for the AFLW competition and its players.
Published in the , the study investigated sex differences in sleep, circadian rhythms and mental health, as well as the moderating role of sex in the prediction of mental health, among AFL and AFLW players.
Participants included 87 elite Australian Rules footballers, of whom 43 per cent were female. Their mean age was 24. They completed questionnaires, two weeks of sleep/wake monitoring, and a biological clock assessment. Data were collected during their pre-season training periods over two seasons.
The AFLW players, relative to male players, reported poorer mental health (a higher athlete psychological strain score), had later sleep-wake timing (by 28 mins), reported a greater preference towards being a ‘night owl’, and had a later body clock measured by the hormone melatonin (by 33 mins).
For the female athletes, less efficient sleep and more irregular sleep were associated with poorer mental health. In addition, those that were more extreme morning or evening types and those who were not in sync with their body clocks reported poorer mental health.
However, when it came to the male AFL players, the researchers found no significant relationships between these factors.
First author and PhD candidate , from the Monash University School of Psychological Sciences, said the findings were relevant for athletes.
“Our findings suggest that athletes and sports organisations should consider monitoring sleep and body clocks in the management of mental health, and this may be of particular value to those who may be vulnerable to disruption,” Mr Mascaro said.
Senior author and Deputy Director of the School’s Sleep and Circadian Rhythms Research Program, – and her team – had been conducting research with elite athletes across the AFL, NRL and NBL for the last few years and recognised the importance of these results.
“Our findings might be associated with factors relevant to the elite semi-professional status versus elite full-time professional, such as training schedules, remuneration and access to support,” Dr Facer-Childs said. “More research is needed to tease apart the possible environmental or biological mechanisms at play, and to monitor outcomes longitudinally.
“We have seen a huge increase in the interest of women’s sport over the last few years, and the growth of the AFLW competition is testament to this. However, the majority of sports science research has been conducted in men.
“These findings support the need for more studies with female athletes and the development of tailored programs to improve sleep, circadian alignment and mental health among female semi-professional elite athletes.”
