Kaurukisan Exam Prep: Mastering Sports Mechanics
Are you ready to test your knowledge on sports mechanics and injury prevention? This quiz will challenge you with thought-provoking questions designed to enhance your understanding of biomechanics in running, jumping, and throwing.
- Evaluate your grasp of contraction types and their effects
- Understand the roles of key muscle groups
- Explore injury risks associated with various athletic actions
Which contraction type poses the highest risk of injury during running?
Concentric
Eccentric
What purpose does the glute max have in the 'end of swing' phase during running?
Slow the hip flexors
Propulsion
Prevent tripping
Resist flexion of joints
What purpose do the plantar flexors have in the 'late stance' phase during running?
Propulsion
Prevent tripping
Slow lower leg
What contraction type occurs in the hamstrings in the 'late in swing' phase as they slow knee extension before contact during running?
Eccentric
Concentric
Isometric
Hopping is defined as...
Propelling from one or both feet and then landing on both feet
