Topic 7: Strengthening- isometric exercise

What is isometric exercise?

• An exercise that involves lifting heavy weights

• An exercise that improves postural stability

• An exercise that focuses on dynamic strength

• An exercise given for fatigue muscles

What is the primary factor that determines the intensity of isometric exercise?

• The duration of the exercise

• The type of equipment used

• The angle of the body during exercise

• The amount of force applied

What is the recommended duration for holding an isometric contraction?

• 2- 4 sec

• 6- 10 sec

• 8- 12 sec

• 10-15 sec

What is the purpose of isometric exercise in preventing muscle atrophy?

• To improve joint flexibility

• To improve muscle contractility

• To improve muscle elasticity

• To reduce muscle activity

What is the effect of holding repetitive contractions in isometric exercise?

• Decreases muscle cramping

• Increases muscle cramping

• Reduces effectiveness of the regimen

• Has no impact on muscle strength

What is the recommended exercise intensity for improving strength in isometric exercise?

• 60% of MVC

• 70% of MVC

• 75% of MVC

• 80% of MVC

What is the MAIN benefit of isometric exercise in postural stability?

• Decreases muscle pain

• Improves dynamic muscle strength

• Reduces muscle over work

• Develops static muscle strength

What is the term used to describe isometric exercise with resistance at multiple joint positions?

• Multiple-resistance isometrics

• Dynamic-resistance isometrics

• Dynamic-angle isometrics

• Multiple-angle isometrics

What is the effect of isometric training on dynamic strength?

• Increases dynamic strength

• Decreases dynamic strength

• No impact on dynamic strength

• Improves flexibility

What is the recommended number of resistance points in multiple angle isometrics?

• 2 to 4 points

• 8 to 10 points

• 6 to 8 points

• 4 to 6 points
