Muscle Strength and Endurance

1
Muscle Strength and Endurance
2
Definitions

• Muscle Strength
• Ability to generate some force against some
  resistance
• Muscle Endurance
• Ability to perform low-intensity repetitive
  exercise over prolonged time period
• Power
• Strength that is applied over a distance for a
  specific time
• Relationship between muscle strength and
  endurance
• Resistance Exercise

3
Goals and Indications for Resistance Exercise

• Increase Strength
• Outcomes of resistance training
• Hypertrophy
• Recruitment of fibers
• Neuromuscular Efficiency
• Fiber Type
• Biomechanical Considerations
• Joint angle
• Length-tension relationship

4
Precautions to Strength Training

• Cardiovascular
• Valsalva maneuver
• Increases intrabdominal and intrathoracic
  pressure
• Fatigue
• Local and Total Body Fatigue
• Recovery Times
• Acute exercise 3-4 minutes 90-95 ore-exercise
  capacity
• Changes that occur
• Mild exercise
• Overtraining
• Substitute Motions
• DOMS

5
Contraindications to Strength Training

• Inflammation Phase
• Pain

6
Things to Consider in Developing Strength
Training Program

• Intensity
• Bouts and Frequency of Exercise
• Duration
• Speed of Exercise
• Mode of Exercise
• Static vs Dynamic
• Open vs Closed Kinetic Chain
• Which is better?
