KAAP350 - Unit 3 Movement Analysis

What is the primary purpose of the stance phase in movement analysis?

• To reduce muscle activity

• To prepare for a jump

• To initiate a sport skill with a balanced body position

• To increase flexibility

During the preparatory phase, what happens to the muscles?

• Muscles relax completely

• Muscles lengthen and antagonists concentrically contract

• Muscles shorten and agonists eccentrically contract

• No significant muscle activity occurs

What type of muscle activity occurs during the movement phase of a sport skill?

• Isometric activity in involved muscles

• Concentric activity in involved muscles

• Eccentric activity in involved muscles

• No muscle activity

What occurs in the antagonist muscles during the follow-through phase of movement?

• Concentric contraction

• Isometric holding

• Eccentric activity

• Complete relaxation

What is the goal of the recovery phase in movement analysis?

• To increase muscle tension

• To return to a functional position

• To prepare for the next physical activity

• To relax all muscles completely

What is a characteristic of exercises that are classified as closed kinetic chain?

• The distal end of the limb is fixed to a surface

• The joint can move independently of other joints

• Movement of one joint necessitates the movement of other joints in the extremity

• Only the upper body is involved

Which of the following is an example of an open kinetic chain exercise?

• Squat

• Dead-lift

• Biceps curl

• Pull-up

In closed kinetic chain exercises, which of the following is NOT an example?

• Bench press

• Push-up

• Squat

• Olympic lift

What does the Overload Principle in physical training emphasize?

• The need for consistent exercise without variation

• The importance of mental stress in muscle growth

• The necessity of physical stress for muscle adaptation and growth

• The role of dietary supplements in muscle development

According to the Overload Principle, which factor is NOT considered when determining the physical stress needed for muscle growth?

• Frequency of exercise per week

• Intensity as a percentage of maximum weight

• Type of dietary intake

• Time or duration of training
