HIIT:n vaikutukset luun aineenvaihduntaan kroonista aivohalvausta sairastavilla henkilöillä

torstai 17. syyskuuta 2026 päivittänyt: The Hong Kong Polytechnic University

Korkean intensiteetin intervalliharjoittelun vaikutukset luun aineenvaihduntaan kroonista aivohalvausta sairastavilla henkilöillä: oivallus, satunnaistettu kontrolloitu koe

Objectives: To investigate the effects of high-intensity interval training (HIIT) on musculoskeletal fitness in chronic stroke survivors.

Hypothesis to be tested: HIIT, performed on a recumbent stepper, will significantly enhance muscle power in chronic stroke survivors when compared with moderate-intensity continuous training (MICT) Design and subjects: Assessor-blinded, stratified, randomised, placebo-controlled clinical trial involving eligible 66 chronic stroke survivors.

Interventions: Participants will be randomly allocated to one of three groups: the HIIT group, the MICT group, or a stretching group (active control). Each group will attend sessions three times per week for 12 consecutive weeks, totaling 36 training sessions.

Main outcome measures: Assessments will be conducted at baseline, at mid-term of the intervention (week 6), at the end of the intervention (week 12), and at a 12-week follow-up (week 24). The primary outcome measure will be muscle power. Secondary outcome measures will include muscle strength, body composition, biomarkers, motor function, balance function, cardiorespiratory response, and psychosocial response.

Aseet ja interventiot

Osallistujaryhmä / Arm
Interventio / Hoito
Kokeellinen: High-intensity interval training

The HIIT session will consist of a 3-minute warm-up, a 20-minute main exercise, and a 2-minute cool-down. The main exercise for HIIT will include ten high-intensity intervals, interspersed with ten low-intensity intervals.
Käyttäytyminen: High-intensity Interval Training

There will be three sessions per week for 12 consecutive weeks, totaling 36 training sessions.
Active Comparator: Moderate-intensity continuous training

The MICT session will consist of a 3-minute warm-up, a main exercise that approximately matches the total workload of the HIIT session (lasting about 30 minutes), and a 2-minute cool-down. The intensity during the main exercise for MICT will remain below the vigorous level by progressively adjusting the workload throughout the intervention period.
Käyttäytyminen: Moderate-Intensity Continuous Training

There will be three sessions per week for 12 consecutive weeks, totaling 36 training sessions.
Active Comparator: Stretching

The stretching group will receive 25 minutes of whole-body stretching.
Käyttäytyminen: Stretching

There will be three sessions per week for 12 consecutive weeks, totaling 36 training sessions.
