In a randomisation crossover design, the study was divided into caffeinated chewing gum trial (CCG) and placebo trail (PL). Participants wore a heart rate monitor to record their heart rate and heart rate variability during the experiment, and were given either a caffeinated chewing gum containing 3 mg/kg of body weight (CAP trial) or a placebo chewing gum, and rested for 15 minutes. After the warm-up, the athletic ability test and shot put performance were conducted in order. Saliva samples were collected for analysis of caffeine and α-amylase before and at the end of the experiment.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '40 Years', 'minimumAge': '20 Years', 'genderBased': True, 'genderDescription': 'Only male subjects', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* activity athlete\n* No cardiovascular and joint diseases\n\nExclusion Criteria:\n\n* Non-active athlete\n* Caffeine-sensitive individuals'}, 'identificationModule': {'nctId': 'NCT07412951', 'briefTitle': 'Effects of Caffeine and Shot Put Performance', 'organization': {'class': 'OTHER', 'fullName': 'National Taiwan Sport University'}, 'officialTitle': 'Effects of Caffeinated Chewing Gum on Shot Put Performance', 'orgStudyIdInfo': {'id': '115-2'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'caffeine gum', 'description': 'Chewing caffeine gum for 10 minutes', 'interventionNames': ['Dietary Supplement: caffeine']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'placebo gum', 'description': 'Chewing placebo gum for 10 minutes', 'interventionNames': ['Dietary Supplement: caffeine']}], 'interventions': [{'name': 'caffeine', 'type': 'DIETARY_SUPPLEMENT', 'description': 'The participants chewing either caffeine Gum (CAF trial, containing 3 mg/kg of caffeine) or Placebo Gum (PL) for 10 minutes.', 'armGroupLabels': ['caffeine gum', 'placebo gum']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Taichung', 'country': 'Taiwan', 'facility': 'National Taiwan University of Sport', 'geoPoint': {'lat': 24.1469, 'lon': 120.6839}}], 'overallOfficials': [{'name': 'Chih-Hui Chiu', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Sport Science Research Center'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'National Taiwan Sport University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor', 'investigatorFullName': 'Chih-Hui Chiu', 'investigatorAffiliation': 'National Taiwan Sport University'}}}}
