Our data in active men and women showed that interval training is viewed as more enjoyable than higher volume moderate exercise.', 'detailedDescription': 'Twelve men and women who were habitually active initially performed ramp exercise on a cycle ergometer to assess maximal oxygen uptake (VO2max) and peak power output (PPO), which was used to determine workload for the subsequent 2 bouts. They returned at least 48 h later at the same time of day to complete high intensity interval training (HIIT consisting of repeated 1 min bouts at 85 %PPO) or moderate intensity continuous training (MICT consisting of 25 min at 40 %PPO). During exercise, heart rate, oxygen uptake, perceived exertion, pleasure:displeasure, and blood lactate concentration were continuously assessed. Ten minutes post-exercise, physical activity enjoyment was measured. Data showed that despite higher oxygen uptake, heart rate, blood lactate concentration, and perceived exertion in HIIT, enjoyment was higher in HIIT versus MICT.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '45 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Habitually active young men and women ages 18-45 yr', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Habitually active, healthy, non-obese\n\nExclusion Criteria:\n\n* Sedentary, unhealthy, joint pain precluding tolerance to exercise'}, 'identificationModule': {'nctId': 'NCT02981667', 'briefTitle': 'Higher Enjoyment in Response to High Intensity Interval Training Versus Moderate Intensity Continuous Exercise', 'organization': {'class': 'OTHER', 'fullName': 'California State University, San Marcos'}, 'officialTitle': 'Enjoyment Responses to High Intensity Interval Training and Moderate Intensity Continuous Exercise', 'orgStudyIdInfo': {'id': 'astorino1'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Active men and women', 'description': 'Healthy, active men and women ages 18-45 yr completed 1 bout of high intensity interval training and moderate intensity continuous training in a randomized, crossover design.', 'interventionNames': ['Other: Exercise intensity']}], 'interventions': [{'name': 'Exercise intensity', 'type': 'OTHER', 'description': 'Participants were randomized to 1 or 2 exercise intensities, moderate or high (interval training).', 'armGroupLabels': ['Active men and women']}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'Data are accepted for publication in PLoS One, an open-access journal, which makes the aggregate data available to all researchers.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'California State University, San Marcos', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor, Dept. of Kinesiology', 'investigatorFullName': 'Todd A.
