The Golgi tendon organ is an essential component of static stretching because it
prevents muscle from being placed under excessive tension.
The force-couple relationship that allows for the upward rotation of the scapula?
Upper trapezus and lower portions of the serratus anterior
Deoxygenated blood is pumped from the right ventricle to the lungs through which vessel?
Dynamic stretching improves soft tissue extensibility by using what?
The oxidative system is primarily used when a client
jogs for 30 minutes
What would aid the primary respiratory muscles in breathing after a set of maximum effort sprints?
When an exercise is high intensity and lasts about 10 seconds, what is the energy pathway that is predominantly used?
A client who is practicing repeated squat exercises in order to create permanent changes in her technique is exhibiting
What stimulates muscle fibers to go through a series of steps that initiate muscle contractions?
What exercise uses a ball-and-socket joint as the primary mover?
Seated dumbbell lateral raise (shoulder)
The body's ability to differentiate between walking on concrete and walking on sand is an example of what function of the nervous system?
If a client exhibits increased force output of his hamstrings and adductor magnus to compensate for a weakened gluteus maximus during hip extension, this is an example of what?
If a client squats with his feet excessively externally rotated, it is evidence of what?
A functional unit of muscle
A structure of skeletal muscle that contains a combination of glycogen, fats, minerals and oxygen-binding myoglobin
A method to estimate the maximum heart rate of a client
Subtract the client's age from 220.
After performing a 3-minute step test, it is determined that a client falls in the "Fair" category for cardiovascular fitness. What is the appropriate starting zone for the client?
What muscle is probably underactive if a client's support or standing leg falls inward during a single-leg squat assessment?
A trainer is working with a senior client. The trainer should be aware of what physiological characteristic?
Decreased lean body mass
A client's head protrudes during a pulling assessment. What muscles should be stretched?
What is the purpose of the Davies test assessment?
Assessing upper extremity agility and stabilzation
During the overhead squat assessment, the client's arms fall forward. What muscles are considered to be overactive?
The client's feet turn out when performing the overhead squat assessment. What muscle is likely overactive?
Why is it crucial to have a client complete the PAR-Q?
It helps detect any possible cardiorespiratory dysfunction.
A personal trainer observes that a client leans forward excessively while performing an overhead squat. Based on this observation, the appropriate action is to
Static stretch the soleus, gastrocnemius, hip flexor complex and abdominal complex
What muscle is likely overactive if a client's head protrudes forward during the pushing assessment?
In order to ensure accuracy while taking resting heart rate, it is best that all three tests be taken
at the same time each day
What assessment is commonly used in exercise physiology laboratories to measure body fat composition?
During a standing pulling assessment, a client compensates by moving his head forward. Which of the following static stretches would be appropriate for this client?
