Core Concepts
Components of Fitness
Cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition.
FITT Principle
Frequency, Intensity, Time, and Type โ the four variables for designing effective exercise programs.
Aerobic vs Anaerobic
Aerobic: with oxygen, sustained activity (running, swimming). Anaerobic: without oxygen, short bursts (sprinting, weightlifting).
Motor Skill Development
The progression of movement skills from fundamental (running, throwing) to specialized (sport-specific techniques).
Periodization
Systematic planning of training phases: preparation, competition, recovery.
Worked Examples & Applications
FITT Principle Example: Cardiovascular training: Frequency = 3-5 days/week, Intensity = 60-80% max HR, Time = 20-60 minutes, Type = running, cycling, swimming.
Target Heart Rate Calculation: Karvonen Formula: Target HR = [(Max HR โ Resting HR) ร %Intensity] + Resting HR. Example: Max HR = 220 โ 25 = 195. Resting HR = 60. 70% intensity: (195โ60) ร 0.70 + 60 = 154.5 bpm.
