• Cardiorespiratory endurance
• Flexibility
• Body composition
• Muscular strength

• Muscular endurance

6
Introduction

• A high level of fitness is important to
  competitive athletes
• General fitness is a prerequisite for the optimal
  development of sport-specific fitness

Muscular Strength
14
Muscular Strength

• The ability of a muscle or muscle group to exert
  force against a resistance
• Commonly measured as a maximal value
• Force and strength are synonymous (greater muscle
  mass results in greater strength)
• Force Mass x Acceleration

15
Power
16
Power

• The ability to overcome external resistance at a
  high rate of muscular contraction
• The ability to exert force is dependent on
  muscular strength
• Therefore, power is a derivative of muscular
  strength
