Effecten van HIIT op het botmetabolisme bij personen met een chronische beroerte
Effecten van intervaltraining met hoge intensiteit op het botmetabolisme bij personen met een chronische beroerte: een proof-of-concept, gerandomiseerde gecontroleerde studie
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.

Experimenteel: 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. |
There will be three sessions per week for 12 consecutive weeks, totaling 36 training sessions. |
|
Actieve vergelijker: 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. |
There will be three sessions per week for 12 consecutive weeks, totaling 36 training sessions. |
|
Actieve vergelijker: Stretching
The stretching group will receive 25 minutes of whole-body stretching. |
There will be three sessions per week for 12 consecutive weeks, totaling 36 training sessions. |
