Practice Exam Flashcards
What is a limiting factor for how long anaerobic glycolysis can proceed?
Free hydrogen ions
Improved performance during a plyometric jump is dependent upon what?
Rapid amortization phase
How many minutes of vigorous exercise in hot, humid environments should children be restricted to (including frequent rest periods)?
30 minutes
Local muscles typically consist of which type of muscle fibers?
Type 1
What does the electron transport chain (ETC) do?
The ETC uses a hydrogen gradient to create ATP.
Scoliosis refers to deviations of the spine in which plane of motion?
Frontal Plane
Divides body into top + bottom
Transverse Plane
Divides body into front + back
Frontal Plane
Divides body into right + left
Sagittal Plane
What are the two primary actions of the muscle spindle?
Sense the change in muscle length and the speed of length change
What muscles does the tubing (shoulder) external rotation exercise primarily target?
Infraspinatus and teres minor
What best describes triple flexion when referring to frontside mechanics?
Ankle dorsiflexion, knee flexion, and hip flexion of the lead leg
What is excess postexercise oxygen consumption (EPOC)?
EPOC is the increase in aerobic metabolism above baseline that occurs for a period after exercise.
Define Lordosis
Lordosis is the natural curve of the lower back (lumbar) area of the spine. With an extreme curve, the lower spine will have a deep curve, causing the abdomen (stomach area) to stick out and causing the pelvis (hip areas) to curve back and up. Lower Crossed Syndrome.
Define Kyphosis
Kyphosis is an exaggerated, forward rounding of the upper back. Upper Crossed Syndrome.
For effective weight loss, how many calories should obese clients expend per exercise session?
200-300 kcal
How many Essential Amino Acids (EAAs) are there?
9
How many Nonessential Amino Acids are there?
11
What component of breathing improves blood flow back to the heart?
Inspiration with a decrease in intrathoracic pressure
Quadratus lumborum
Deepest back muscle
Which of the following modalities is most likely to allow for strength and/or power development in the transverse plane?
Medicine Balls
Which test provides the most personalized assessment of an individual’s true metabolic function?
VT1 Test
Define Isokinetic
A type of exercise that accommodates effort whereby the harder the individual pushes or pulls, the more resistance they feel, despite the movement speed remaining constant
Pronation of the foot describes what multiplanar movements?
Eversion, dorsiflexion, and ankle abduction
What are the recommended training variables for static stretching?
1 to 3 sets, hold each stretch for 30 seconds
For an individual training in stage 1, what training volume and frequency would qualify that person to progress to stage 2?
Ability to maintain zone 1 intensity for at least 30 minutes, 3 times per week
Using battle ropes is considered which sort of exercise?
Low-impact activity
How should the amortization phase of the stretch-shortening cycle be described?
The transition from eccentric loading to concentric unloading
The upper trapezius works with what muscle as a force couple to create upward rotation of the scapula?
Serratus anterior
What is the general recommended rest between SAQ reps for beginner clients?
15-60 seconds
Name an effect of the cardiovascular system that occurs during exercise
Increased Ventricular Filling
Which of the following would make a person better at oxidizing fat?
Having more mitochondria in their muscle
The ability of a test to produce consistent and repeatable results
Reliability
The ability to react and change body position with maximal force production, in all planes of motion, and from all body positions
Quickness
The human body’s ability to respond to the information received from the sensory nervous system.
Motor function
When glucose is broken down via glycolysis, what molecule is created that could also be oxidized under aerobic conditions?
Pyruvate
Starting at what percentage of bone density loss does the risk of hip fracture increase by 2.5 times?
10%
Triple Extension in Backside Mechanics
Knee Extension, Hip Extension, Ankle Plantar Flexion
The degree to which a test specifically measures what it is intended to measure
Validity
Transverse Abdominus
The deepest of the 6 abdominal muscles. Local muscle of the core. It extends between the ribs and the pelvis, wrapping around the trunk from front to back. (Drawing-in maneuver targets these muscles)
Which of the following benefits may occur as a result of exercises that comprise only eccentric muscle actions that are appropriately loaded?
Increased anabolic hormone stimulation
Type 1 Muscle Fibers
Slow twitch: Rich in capillaries, increased oxygen, smaller, numerous mitochondria, less force production, slow fatigue
