Sports Medicine Practice
Exam
Course Introduction
Sports Medicine is a multidisciplinary field focused on the prevention, diagnosis, treatment, and rehabilitation of injuries related to physical activity and sports. This course explores key concepts in human anatomy and physiology, the mechanisms of sports-related injuries, and the application of evidence-based strategies for injury management and performance enhancement. Students will examine topics such as athletic training principles, emergency care, injury assessment, nutrition, biomechanics, and rehabilitation techniques. Emphasis is placed on the holistic care of athletes, ethical considerations, and the role of sports medicine professionals in promoting health and safe participation in sports across various populations.

Q1) Define the terms hypermobility and hypomobility as each refers to human motion.
Answer: Mobility of joints is assessed passively and refers to the amount of motion that is available (rather than that which someone necessarily uses actively).Hypermobility refers to excessive joint mobility.It generally results from inadequate support from structures such as joint capsule or ligaments (torn ligaments,plastic ligaments,or high elastin content).Hypermobility may also result from inadequate muscular support (e.g.,weak or hypotonic muscles)around the joint.Hypomobility refers to limited joint mobility.It generally results from bony limitations to motion (e.g.,large bony prominences,bone spurs),adaptively shortened joint capsule or ligaments,or excessive muscle support around the joint (e.g.,hypertonic muscles or adaptively shortened muscles).
Q2) Increasing the rate of application of a force causes a ligament to ____________________.
A) store less energy to failure
B) require more force to rupture
C) decrease stiffness
D) elongate more

Sample Questions
Q1) The human body selectively recruits one size motor unit before another.Which size is recruited first,and why is this efficient?
Answer: Small motor units are recruited before large so that the "first" response is a small,relatively slow one.This allows the body to gauge the need for a large response in order to prevent both overresponse and waste of energy.
Q2) What must happen before a motor unit will fire (discharge)? What occurs immediately after discharge of the motor unit?
Answer: In order for a motor unit to discharge,there must be sufficient facilitation (buildup of charges)at the anterior horn cell (AHC).Once threshold is reached,an impulse is conducted down the axon and all innervated fibers contract.Immediately after firing and fiber contraction,the motor unit goes through latency,or a refractory period,during which depolarization cannot occur.
Q3) Aging will cause the following normal connective tissue change:
A) Decreased connective tissue stiffness
B) Increase in the amount of connective tissue in the extracellular matrix
C) Increase in the number of motor units
D) Decrease of sarcopenia
