Long Term Effects of Physical Training

• Modifications in
• Heart Rate
• Stroke Volume
• Cardiac Output
• Blood Volume
• Heart Volume
• Respiration
• Metabolism

4
Aerobic Capacity

• Is finite
• Improves by 5 to 25 with training
• Decreases with aging
• Decrease slower in those who are physically fit.
• The training effect is lost in stages if exercise
  is interrupted or discontinued.

5
Exercise

• Blood pressure

Exercise

• The principles of exercise can be manipulated to
  meet any exercise objective.
• Exercising by varying the activities per exercise
  session or during exercise sessions is
  cross-training.
• The heat generated by exercise is lost from the
  body by conduction, convection, radiation, and
  evaporation.
• Evaporation of sweat is the major mechanism for
  ridding the body of heat that develops during
  exercise.
• Hypothermia is the most severe problem associated
  with exercise in cold weather.
