[Effect of corticosteroids on inspiratory muscle function]

|December 1, 1994
Summary
Corticosteroids weaken inspiratory muscles, reducing strength and endurance. Inspiratory muscle training prevents this decline, while tapering steroid dosage aids recovery.
Area of Science:
- Respiratory Medicine
- Muscle Physiology
Context:
- Corticosteroids are widely used for nonrespiratory conditions.
- Potential side effects on respiratory muscle function are not fully understood.
Purpose:
- To evaluate the impact of corticosteroids on inspiratory muscle strength and endurance.
- To assess the efficacy of inspiratory muscle training in preventing corticosteroid-induced muscle weakness.
Summary:
- Corticosteroid administration led to decreased maximal inspiratory mouth pressure (PImax) and inspiratory muscle endurance.
- Tapering corticosteroid dosage improved inspiratory muscle function.
- Specific inspiratory muscle training prevented the decline in inspiratory muscle strength and endurance during corticosteroid therapy, unlike sham training.
Impact:
- Corticosteroids significantly impair respiratory muscle function.
- This impairment is reversible with dose reduction and preventable with targeted exercise.
- Highlights the importance of monitoring and mitigating side effects of corticosteroid therapy on respiratory health.
