Upper‐Limb High‐Intensity Interval Training or Passive Heat Therapy (Heat) Therapy to Optimize Cardiorespiratory Fitness Prior to Total Hip or Knee Arthroplasty: A Randomized Controlled Trial
Authors' conclusion
Heat therapy and HIIT improved indices of cardiorespiratory fitness preoperatively in patients who have difficulty performing lower-limb exercise.
Study context
- Population
- Participants with severe knee or hip OA awaiting joint replacement surgery
- Participants
- 93 participants
- Comparison
- Upper-limb high-intensity interval training (HIIT) vs passive heat therapy vs home-based exercise before total hip or knee arthroplasty
- Primary endpoint
- Peak oxygen consumption (V̇O2) on cardiopulmonary exercise testing
Primary result
As reported in the abstract
Peak V̇O2
Difference
+2.5 mL × min-1 × kg-1
95% CI 0.5–4.4P = 0.009
HIIT vs Heat
Difference
+3.2 mL × min-1 × kg-1
95% CI 1.2–5.2P = 0.001
HIIT vs Home
- Peak V̇O2 increased across HIIT
- 16%
