Unit 3 - Biomechanics Summative Test

How should the arms move during the arm swing phase of a vertical jump?

• Arms should swing powerfully upward

• Arms should stay at the sides

• Arms should cross in front of the body

• Arms should be kept behind the back

Which phase of the vertical jump involves controlled eccentric loading that activates the quads and glutes?

• Eccentric Phase

• Concentric Phase

• Arm Swing

• Landing

Why is the arm swing important during a vertical jump?

• It helps maintain balance

• It should swing powerfully upward to aid the jump

• It keeps the arms relaxed

• It prevents injury

Which of the following is NOT a reason to perform a jump analysis according to the lecture material?

• To choose the right exercises

• To progress or regress drills

• To track fatigue and readiness

• To improve nutrition planning

What is the significance of improving reactive strength in jump analysis?

• It allows for quick ground contact during plyometrics and sport moves

• It increases the time spent in the air

• It reduces the need for arm movement

• It focuses only on flexibility

What is a potential consequence of ignoring asymmetries found during a jump analysis?

• Increased risk of injury to lower body joints

• Enhanced cardiovascular endurance

• Improved flexibility in the upper body

• Better coordination of arm movements

How can jump analysis be used after an injury?

• To determine if the athlete has gained weight

• To check if mechanics and symmetry have returned

• To measure the athlete's height

• To assess the athlete's nutrition

Which of the following patterns is considered risky and can be spotted during a jump analysis?

• Knee valgus

• High jump height

• Fast running

• Deep breathing

Which condition is shown in the diagram where the knees angle inward?

• Knock knees (valgus)

• Normal alignment

• Bow legs (varus)

• Flat feet

What should be observed when analyzing knee alignment during running gait?

• Whether the knees are bent or straight

• Whether the alignment is inward, outward, or neutral

• The speed of knee movement

• The color of the runner's shoes
