Assessment of energy availability and associated risk factors in professional female soccer playersThis study aimed to assess energy availability (EA), alongside possible risk factors of reduced or low EA of professional female soccer players during a competitive season. Thirteen players (age: 23.7 ± 3.4 y, stature: 1.69 ± 0.08 m, body mass: 63.7 ± 7.0 kg) engaged in a 5-day (two rest days, one light training, heavy training and match day) monitoring period. Energy intake (EI) and expenditure during exercise (EEE) were measured. EA was calculated and categorised as optimal, reduced or low (≥45, 31-44, ≤30 kcal·kg FFM-1·day-1, respectively). Relationships between EA and bone mineral density, resting metabolic rate (RMR), plasma micronutrient status, biochemical markers and survey data were assessed. EA was optimal for 15%, reduced for 62% and low for 23% of players. Higher EA was observed on rest days compared to others (P<0.05). EA was higher for the light compared to the heavy training day (P<0.001). EEE differed significantly between days (P<0.05). EI (2124 ± 444 kcal), carbohydrate (3.31 ± 0.64 g·kg·day-1) and protein (1.83 ± 0.41 g·kg·day-1) intake remained similar (P>0.05). Survey data revealed 23% scored ≥ 8 on the Low Energy Availability in Females Questionnaire and met criteria for low RMR (ratio <0.90). Relationships between EA and risk factors were inconclusive. Most players displayed reduced EA and did not alter EI or carbohydrate intake to training or match demands. Although cases of low EA were identified, further work is needed to investigate possible long-term effects and risk factors of low and reduced EA separately to inform player recommendations.
When transport policy becomes health policy: A documentary analysis of active travel policy in EnglandThere has been a succession of policy documents related to active travel published by the British government since the implementation of a National Cycle Network (NCN) in 1995. However, as the latest National Travel Survey (NTS) reveals, the number of journeys made by bike in the UK has remained steadfastly around only 2% (Department for Transport [DfT], 2018a). By using documentary analysis of the available official policy documents and statements, the aim of this paper is to make sense of the policies that have been published concerning active travel (AT) in England. This is done from a figurational sociological perspective. Three key themes emerge from the analysis: (1) the rhetorical, advisory level of the vast majority of the policies; (2) the reliance on a wide network of local authorities to implement AT policy; and (3) the focus placed on individuals to change their behaviour. Furthermore, the analysis reveals that despite a large number of policy publications from a range of government departments claiming to promote AT, little has actually changed in this time period in terms of a national agenda. Despite the successive policies, it seems there is little appetite on behalf of recent governments to make widespread infrastructural changes, where instead the focus has largely been on persuading the individual to seek more active modes of travel, increasingly for their own, individual ‘health’ gains.
