ENS 331 Exam 2 Pre Questions With
Already Correct Answers.
Power: - Answer Rate at which work is performed (per unit time) or the velocity of force
production.
Speed: - Answer Ability to initiate movement rapidly (explosive) and achieve high-running
velocity.
Agility: - Answer Ability to rapidly and accurately change movement speed and direction
Coordination: - Answer Ability to process and execute appropriate action with proper
sequence and magnitude
Reactivity: - Answer Ability to rapidly respond to stimuli: reaction time (rate of processing
info.) and response time (rate of producing motor responses)
Balance-Static: - Answer Ability to maintain body's center of mass within its base of support
(standing)
Balance-Dynamic: - Answer Ability to move outside of body's base of support, yet maintain
postural control (walking)
Aerobic Fitness: - Answer Ability of cardiopulmonary system to efficiently deliver oxygen and
nutrients to cells, and of aerobic energy state.
Anaerobic Fitness: - Answer Ability of the anaerobic energy system to initiate and change in
activity (e.g., sit to walk) and sustain higher-intensity, shorter-duration bouts of activity
Flexibility: - Answer Amount of unrestricted, 3-dimensional movement available at, or across a
joint-determined by extensibility of muscle and other structures, and influenced by the nervous
system.
-Also defined as range of motion at a joint/ joints
, Muscular Strength: - Answer Ability of muscles to generate a maximal amounts of force
against external resistance (strength training, big load)
Describe methods by which one can to increase the balance challenge of an exercise: - Answer
a. develop static balance before dynamic, incorporate balance drills at beginning of training
b. duration, line of gravity, points of contact, base of support, sensory alteration, sensory
removal, center of mass, additional unstable surfaces, external perturbances
Describe the common symptoms associated with overtraining syndrome: - Answer a.
decreased performance over 1-2 week period
b. increased resting heart rate/blood pressure
c. decreased body weight
d. reduced appetite or loss of appetite; nausea
e. disturbed sleep patterns and inability to attain restful sleep
f. muscle soreness and general irritability
g. lack of motivation/adherence
Explain the causes of muscle soreness and when it is mostly likely to occur: - Answer a. acute
muscle soreness
i. happens during or after workout
ii. accumulation of waste products of exercise in muscles
1. H+ ions - lactate formation
2. fluid shift (from blood to tissue) exerting pressure on pain receptors
iii. ions change chemistry and fluid change physical properties of the tissue, activating receptors
creating pain and maybe muscle spasm, later body is restored to normal
iv. disappears within 30-60 minutes after exercise
