Effects of a 12-week HIIT\u2009+\u2009group mediated cognitive behavioural intervention on quality of life among inactive adults with coeliac disease: findings from the pilot MOVE-C study.
Abstract
OBJECTIVE\nThe purpose of the pilot MOVE-C study was to examine the effects of a 12-week high-intensity interval training (HIIT) plus lifestyle education program on quality of life (QoL), behavioural and psychosocial outcomes among inactive adults with coeliac disease.\n\n\nDESIGN\nThis study used a 3 (time: baseline, immediately post and three months post) × 2 (group: experimental versus waitlist control) mixed design. After completing baseline testing, 41 participants were randomised to one of two groups: HIIT\u2009+\u2009or waitlist control (WLC). The HIIT\u2009+\u2009intervention involved twice-weekly HIIT, during which participants progressed to 14\u2009×\u200930\u2009s intervals (90% heart rate max; HRmax), with 2-minute recovery (50% HRmax). The HIIT\u2009+\u2009intervention also included six bi-weekly education sessions.\n\n\nRESULTS\nParticipants in HIIT\u2009+\u2009reported significant improvements in QoL and exercise behaviour immediately post-intervention, and this was sustained three months post-intervention, whereas no changes in QoL nor exercise behaviour were reported in WLC. Improvements were also reported among HIIT\u2009+\u2009immediately after the intervention for gastrointestinal symptoms and self-compassion. All participants reported significant improvements in adherence to a GFD immediately post-intervention.\n\n\nCONCLUSION\nFindings from this pilot study provide preliminary evidence that a tailored exercise and lifestyle intervention can lead to improved QoL, exercise behaviour, gastrointestinal symptoms and self-compassion among inactive adults with coeliac disease.
