Kinesiology Exam
Solutions
Course Introduction
Kinesiology is the scientific study of human movement, performance, and function. This course explores the anatomical, physiological, biomechanical, and psychological principles underlying physical activity and motor skills. Students will examine the structure and function of the musculoskeletal system, the mechanics of movement, and the influence of physical activity on health and well-being. Topics include muscle physiology, movement analysis, skill acquisition, and the effects of exercise on the human body, providing a foundational understanding applicable to careers in health, fitness, sports, and rehabilitation sciences.

Answer: B
Q2) Define modulus of elasticity,stiffness,brittleness,and ductility.
Answer: The modulus of elasticity is the ratio of stress to strain at any point in the stress-strain curve.A large applied load that results in only a small deformation will have a high modulus of elasticity.The steeper the stress-strain curve,the higher is the modulus of elasticity.Because the material does not readily respond to an applied load,it is considered stiff (therefore,stiffness is equivalent to the modulus of elasticity).A tissue is brittle when the plastic region is very small or absent-that is,the material undergoes very little deformation prior to ultimate failure.A ductile material,in contrast,can undergo considerable deformation prior to failure.

Q1) 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
Answer: B
Q2) In order to produce maximum torque for an isokinetic concentric contraction,should the speed of the motion be fast or slow? For an isokinetic eccentric contraction?
Answer: Isokinetic contractions are most commonly concentric but may also be produced eccentrically.A slower concentric contraction will always produce greater tension than a faster one using the same number of motor units.The slowest isokinetic contraction (therefore,the one producing the greatest tension)is one that does not produce movement (that is,an isometric contraction-0°/sec).In an eccentric isokinetic contraction,a faster speed produces more tension than a slower contraction using the same number of motor units.Consequently,peak isokinetic eccentric torque will be greater for a given muscle with faster machine settings,as long as the person can maintain the preset speed.
