The MRI scan is used to measure fat stored in the liver and muscles. A continuous glucose monitoring (CGM) sensor will be inserted to measure insulin sensitivity.\n\nVisit 3: Participants will arrive at the laboratory after an overnight fast (\\>10 h) to undergo a Hyperinsulinaemic euglycaemic clamp to assess whole-body insulin sensitivity. Plasma glucose will be measured at regular intervals and muscle biopsies will be obtained from the vastus lateralis muscle of one leg before and after 2 hours of the clamp.\n\nExercise intervention: Pairs of participants from each group (matched for gender, age and VO2max) will be randomized to undertake 12 weeks of steady walking combined with ingestion of either Acipimox or placebo in a counter-balanced, double-blind design. Supervised treadmill walking sessions will be undertaken at LJMU three times per week, with exercise performed at a speed equivalent to 45% VO2max. Participants will initially exercise for 30 mins per session (weeks 1 and 2), and each session will increase in duration by 5 mins every 2 weeks thereafter, up to 50 minutes of exercise. 1 hour before each walking session, participants will ingest either 250 mg Acipimox or nothing.\n\nPost-intervention assessments: The post-intervention assessments will be identical in all respects to the pre-intervention assessments and will be commenced ≥72 hours after the final training session.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '25 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* BMI \\>28 kg.m-2\n* Pre-diabetic\n* Not currently using any anti-diabetes medication\n* Physically inactive (performing less than two 30 min structured exercise sessions per week for the last year)\n* Not pregnant or currently breast feeding\n* Pre-menopausal\n* Not currently involved in a weight loss programme or using weight loss medication\n\nExclusion Criteria:\n\n* Involved in regular exercise (engaged in more than 2 sessions of structured exercise of \\>30 min per week)\n* Currently using anti-diabetes medication (e.g. insulin, metformin)\n* Currently using niacin/vitamin B3 supplements\n* Pregnant or breast feeding\n* Currently engaged in active weight loss programme or using weight loss medication\n* Diagnosed with chronic kidney disease'}, 'identificationModule': {'nctId': 'NCT03809793', 'briefTitle': 'Can the Health Benefits of a Walking-based Exercise Programme be Enhanced by Co-ingestion of a Lipid-lowering Drug?', 'organization': {'class': 'OTHER', 'fullName': 'Liverpool John Moores University'}, 'officialTitle': 'Can the Health Benefits of a Walking-based Exercise Programme be Enhanced by Co-ingestion of a Lipid-lowering Drug?', 'orgStudyIdInfo': {'id': '250408'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Acipimox ingestion', 'description': 'Individuals in this group will undergo pre-assessments for body composition (DXA), Insulin sensitivity (Hyperinsulinaemic Euglycaemic clamp and continuous glucose monitor), muscle biopsies pre- and post- clamp for analysis of lipid metabolites, liver fat (MRI) and exercise capacity (VO2 max).
