The Umeå High-Intensity Training Study: Feasibility and Effect of High-Intensity Training in Older Sedentary People

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 68 (actual)
• Sponsor: Umeå University · Academic / Other
• Sex: All
• Age: 65 Years
• Healthy volunteers: Accepted

Summary

This randomized controlled trial will evaluate the effect of high-intensity training (HIT) in older sedentary people. Seventy older people, aged 65 and over, will be randomized to HIT or moderate-intensity continuous training (MICT). HIT sessions will consist of 10 repeated 6-seconds regulated high intensity cycling sprints against an individualized load. MICT (control group) sessions will consist of aerobic training regulated against an individualized load set to reach a moderate submaximal exercise intensity. Both groups will be performed twice weekly for 12 weeks. The study will evaluate the effects on 1) Cardiovascular function, 2) Brain health, 3) Muscular function, 4) Psychological health, 5) Physical activity, 6) Metabolic health, and 7) Examine the feasibility (attendance, achieved intensity, adverse events) as well as the experiences of HIT. Most outcomes will be assessed at baseline, 3 months (directly after intervention period), and 9 months by blinded assessors.

Detailed description

Information about modifications of the study protocol (September 2020): Experiences of exercising and its effects were at the 9-month follow-up collected through individual interviews instead of focus group interviews (secondary outcome measures no. 31). Due to Covid-19, at the 9-month follow-up all outcome measurements besides the questionnaire (secondary outcome measures no 9, 10, 11, 12, and 14) and interviews (secondary outcome measure no 31) were terminated for 37 of the participants.
