How Physical Activity Affects Knee Cartilage and a Standard Intervention Procedure for an Exercise Program: A...

Area of Science:

• Biomedical Science
• Sports Medicine
• Orthopedics

Background:

• Cartilage degeneration mechanisms with aging remain unclear.
• The specific effects of physical activity on cartilage health require further elucidation.
• Understanding these factors is crucial for developing effective joint health strategies.

Purpose of the Study:

• To review the impact of diverse physical activity interventions on cartilage.
• To establish a Standard Operating Procedure (SOP) for exercise programs promoting knee joint health.
• To provide a unified direction for future scientific research in cartilage wellness.

Main Methods:

• Systematic literature search across three electronic databases.
• Screening of articles based on predefined eligibility criteria.
• Narrative discussion of outcomes from 24 included studies.

Main Results:

• Included studies encompassed aerobic, strength, flexibility, postural balance, and mobility interventions.
• Various exercise protocols and intervention types were identified across studies.
• Physical activity interventions generally demonstrated positive effects on cartilage structure.

Conclusions:

• Physical activity interventions show promising outcomes for cartilage structure.
• Significant variability exists in current exercise protocols for cartilage wellness.
• A proposed SOP for physical intervention aims to standardize clinical and research approaches to cartilage health.
