One group of participants will receive a WAT-based exercise intervention incorporated with the support of behavioral change techniques (BCTs) and technical issues, while the other group will receive only an exercise intervention incorporated with BCTs support.","overall_status":"Completed","phases":[],"study_type":"INTERVENTIONAL","sponsor":"The Hong Kong Polytechnic University","enrollment":40,"countries":["Hong Kong"],"start_date":"2018-06-01","completion_date":"2020-03-31","last_update_date":"2020-04-09","source_url":"https://clinicaltrials.gov/study/NCT03538418","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
