N1-PA

• Nutrition


  Science of nutrients and other substances for maintenance, growth, reproduction, health and disease
• Physical Activity


  Any bodily movement produced by skeletal muscles that results in energy expenditure (in kJ or kcal)
• Physical Activity


  • Amount of muscle mass
  • Intensity
  • Duration
  • Frequency of contractions
• Exercise


  Planned, structured, repetitive, and purposive physical activity to improve or maintain fitness
• Exercise


  Total daily Physical activity = Exercise + nonexercise
• Sport


  Governed by a set of rules or customs, often competitively, including physical, mind and motor sports
• Physical Fitness


  The capacity of the heart, blood vessels, lungs, and muscles to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations
• Skill-Related Fitness Components


  • Agility
  • Balance
  • Coordination
  • Power
  • Reaction time
  • Speed
• Health-Related Fitness Components

  • Aerobic Fitness
  • Muscular Strength
  • Muscular Endurance
  • Flexibility
  • Body Composition
• Physical activity and physical fitness are related but different concepts
• Methods of measuring physical fitness


  Objective, with consideration of cost, precision, and accuracy

  
• Cardiorespiratory endurance

  • Indicator of body's ability to transport and use oxygen, most important component of health related fitness, negatively related to many diseases, improved by aerobic exercise
• Strength


  Ability of the muscle to exert a single maximum force without strain and undue fatigue
• Muscular endurance

  The ability to repeat submaximal contractions for long periods without undue fatigue
• Flexibility


  The range of motion in a joint, improved by stretching
• Body composition


  The ratio of lean body weight to fat, not too much not too little
• Agility


  • Ability to change direction quickly and accurately during movement, necessary for sports and games
• Balance


  Ability to maintain equilibrium while moving or standing still
• Coordination


  Ability to use senses with the body parts to perform movement tasks, like hand-eye or foot-eye coordination
• Power

  The ability to apply a force at a high rate of speed
• Reaction time


  Elapsed time between a stimulus and the resulting response
• Speed


  The rate at which a movement is performed, important in most sports
