Summary

Intermittent functional training (IFT) can achieve moderate aerobic exercise intensities post-stroke, similar to traditional ergometer training. While both methods showed some benefits, constant-load ergometer exercise yielded greater improvements in cardiorespiratory fitness.

Background:

Moderate-intensity aerobic exercise is crucial for post-stroke recovery and reducing cardiometabolic risks.
Stroke-related impairments often hinder participation in traditional ergometer-based exercise.
Task-oriented circuit training offers a potential alternative for aerobic exercise in stroke survivors.

Purpose of the Study:

To assess if intermittent functional training (IFT) can sustain moderate-intensity aerobic workloads over 10 weeks.
To compare the effects of IFT versus constant-load ergometer exercise (CET) on cardiorespiratory fitness and metabolic profiles in chronic stroke survivors.

Main Methods:

Forty chronic hemiparetic stroke survivors were randomized into IFT or CET groups.
Participants underwent 30 exercise sessions over a 10-week intervention period.
Cardiorespiratory fitness and metabolic markers were assessed pre- and post-intervention.

Main Results:

Both IFT and CET groups sustained moderate-intensity aerobic exercise workloads.
CET demonstrated significantly greater improvements in maximal oxygen uptake compared to IFT.
Combined analysis revealed improvements in C-reactive protein, short-term glycemia, and resting carbohydrate oxidation.

Conclusions:

Intermittent functional training (IFT) effectively replicates the aerobic intensity of constant-load ergometer exercise (CET) in stroke survivors.
While IFT is a viable option, CET may offer superior benefits for cardiorespiratory fitness.
Further research is needed to optimize IFT protocols for secondary stroke prevention across the recovery spectrum.
