Abstract Introduction:<\b>
Appetite and energy intake may be reduced following high-intensity intermittent exercise (HIIE). Yet, exploring such eating behaviour responses at pre-determined time points post-exercise restricts the ecological validity. In addition, the requirement of specialised apparatus questions the effectiveness of many HIIE protocols for public health interventions. Therefore, the purpose of this study was to investigate participant-determined eating behaviour in response to a previously studied protocol, of 2x30seconds or 4x30seconds, of apparatus-free HIIE (star jumps) in inactive, overweight females. Methods:<\b>
Twelve inactive, overweight females will complete three conditions in a randomised, counterbalanced manner. Recruitment and data collection is ongoing; five participants have completed so far. Following a standardised breakfast, participants rested for 2.5hours, before undertaking rest (REST); 2x30seconds (2x30) or 4x30seconds (4x30) of high-intensity intermittent star jumping. Time of request (feeding latency) of, and energy intake at, an ad libitum buffet available following each condition were measured. The complete dataset will be available at the time of the conference. Results:<\b>
Preliminary data (n=5), before statistical analysis, is presented as mean±SD. Following REST, 2x30 and 4x30, feeding latency was 31±16mins, 32±21mins and 30±30mins, respectively, and energy intake was 970±229kcal, 936±222kcal and 782±225kcal, respectively. Conclusion:<\b>
Preliminary results suggest a possible reduction in energy intake following 4x30, despite little change in feeding latency. Final findings will enhance understanding of short-term eating behaviour responses to apparatus-free HIIE in inactive, overweight females. This may inform effective physical activity strategies for regulating acute energy balance.
