Acute physiological, affective and enjoyment responses to apparatus-free protocols of high-intensity intermittent exercise in inactive females ALICE BURGINPhD STUDENTUNIVERSITY OF WORCESTER,  UKAlice Burgin, Dr Andrew Blannin, Prof Derek Peters, Dr Adrian Holliday INTRODUCTION• Perceived lack of time most commonly reported barrier to regular physical activity (Salmon et al., 2003; Cerin et al., 2010)• High-intensity intermittent exercise (HIIE) is posed as a time-efficient physical activity strategy (Gillen & Gibala, 2014)• Many HIIE protocols are high-intensity intermittent cycling-based and so require specialised apparatus (braked cycle ergometer) • Access to facilities and enjoyment are positive correlates whilst perceived effort is a barrier to regular physical activity (Trost et al., 2002)• Biddle & Batterham (2015) propose likely aversive psychological responses which may limit sustainable adoption of HIIE AIM To determine if apparatus-free HIIE elicits similar acute physiological responses and more positive affective and enjoyment responses compared with traditional, apparatus-based HIIE in inactive females.METHODS• 18 inactive females (35±11 years, 25.5±4.1kg•m2, 1244±694 MET minutes•week-1)• Within-subject, counterbalanced, crossover design of 4x30 seconds high-intensity intermittent cycling/squats/star jumpsStandardised breakfast2 hour rest period30 minutes rest periodExercise conditionHeart rate (HR)Blood lactate concentrationRate of perceived exertion (Borg, 1982)Feeling Scale (Hardy & Rejeski, 1989)Physical Activity Enjoyment Scale (Kendzierski & DeCarlo, 1991)RESULTS: HEART RATEF(6, 90) = 4.037, p=0.001, partial Ƞ2=0.212RESULTS: BLOOD LACTATEF(2, 32) = 46.913, p<0.001, partial Ƞ2=0.746RESULTS: RATE OF PERCEIVED EXERTIONχ2 (11) = 164.003, p<0.001χ2 (2) = 10.421, p=0.005χ2 (2) = 12.603, p=0.002RESULTS: AFFECTIVE VALENCEχ2 (8) = 38.158, p<0.001χ2 (2) = 11.623, p=0.003RESULTS: ENJOYMENTχ2 (2) = 16.618, p<0.001CONCLUSIONS• High-intensity intermittent star jumping saw no differences in   heart rate compared with 4x30 seconds of high-intensity intermittent cycling at any time point• High-intensity intermittent star jumping reached blood lactate concentrations similar to previous literature for typical HIIE protocols• Immediately post-exercise, affect was lower in high-intensity intermittent cycling compared with the high-intensity intermittent squat protocol as well as a trend for being lower than the star jump protocol• High-intensity intermittent cycling perceived to be less enjoyable than both the star jumps and squat protocols• High-intensity intermittent star jumping can achieve a high-intensity physiologicalstimulus• No requirement of particular physical activity apparatus or facilities• Preferable levels of enjoyment and significantly lower perceived difficulty compared with traditional cycling-based HIIE, despite similar heartrate reached • Future work to explore effects on long-term health adaptations and markers, including peak oxygenuptake, insulin sensitivity and body compositionIMPLICATIONSTHANK YOU FOR LISTENING!@_aliceburgina.burgin@worc.ac.ukQuestions?
