This document differentiates between health-related and skill-related fitness components. Health-related components include muscular strength, endurance, cardiovascular endurance, flexibility, and body composition, which help reduce disease risk, maintain a healthy weight and lifestyle. Skill-related components include agility, balance, coordination, speed, reaction time and power, which are important for daily living and motor skills, though their importance for survival has lessened over time compared to health-related components. Both types of fitness are beneficial not just for sports but real life, as they improve health, confidence, and ability to perform daily activities.
