Physical and cardiovascular performance in cases with acromegaly after regular short-term exercise

Area of Science:

• Endocrinology
• Exercise Physiology
• Metabolic Disorders

Background:

• Acromegaly, a condition caused by excess growth hormone, often leads to impaired physical performance.
• Evaluating interventions to mitigate these physical deficits is crucial for patient well-being.

Purpose of the Study:

• To assess the impact of a regular exercise program on physical performance in patients with acromegaly.
• To determine if exercise can ameliorate complications associated with acromegaly.

Main Methods:

• Acromegaly patients were divided into exercise and control groups for a 3-month period.
• Physical performance was measured using maximal oxygen consumption (VO2 max), Bruce protocol time, sit and reach test (SRT), and hand grip strength test (HGST).
• Body composition was assessed via BMI, WHR, skinfolds, body fat percentage (PBF), fat mass (FM), and lean body mass (LBM).

Main Results:

• The exercise group showed significant improvements in VO2 max and Bruce protocol time compared to the control group.
• Within the exercise group, VO2 max and Bruce protocol time increased, while heart rate during warming decreased.
• Muscle flexibility (SRT) improved, and body fat percentage and fat mass significantly decreased in the exercise group.

Conclusions:

• Short-term regular exercise can effectively improve physical performance in acromegaly patients.
• Exercise positively impacts muscle activity and body fat composition, suggesting it as a beneficial intervention.
• These findings highlight exercise as a viable strategy to manage acromegaly-related physical impairments.
