The influence of a moderate versus high intensity training program on central pain processing: a pilot feasibility...

Area of Science:

• Exercise physiology
• Pain processing
• Digital health interventions

Background:

• Sedentary lifestyles contribute to chronic pain.
• Blended exercise programs offer flexible, accessible interventions.
• Evaluating novel exercise modalities is crucial for public health.

Purpose of the Study:

• Assess the feasibility of two blended exercise programs (MIT and HIT).
• Explore potential efficacy signals on central pain processing.
• Determine participant adherence, retention, and acceptability.

Main Methods:

• Randomized controlled trial comparing 10-week MIT and HIT programs.
• Blended format: 1 supervised session + 2 tele-supported home sessions/week.
• Quantitative sensory testing (QST) measured central pain processing.

Main Results:

• Feasible recruitment and high adherence in both MIT and HIT groups.
• HIT demonstrated higher participant retention than MIT.
• No significant group differences in QST, but individual responses varied.

Conclusions:

• Blended MIT and HIT programs are feasible for sedentary adults.
• Further research is warranted to optimize implementation and confirm efficacy.
• Individualized responses suggest potential benefits for pain modulation.
