Which sensory receptor will sense a muscle being stretched?
Muscle spindles
Chemoreceptor
Mechanoreceptor
Joint receptor
Muscle spindles are sensory receptors that run parallel to muscle fibers, therefore they are sensitive to when the fibers contract and stretch
Which of these muscle pairings can exhibit reciprocal inhibition and altered reciprocal inhibition?
The bicep and triceps
The pectoral and hamstring
The rear delt and the gastrocnemius
The bicep and the quadriceps
The bicep and triceps are the only agonist and antagonist pairings of muscles from the given options
What kind of stretching involves applying force to tender areas using implements such as a foam roll?
Self-myofascial release stretching
Static stretching
Dynamic stretching
Active-isolated stretching
Self-myofascial release (SMR) stretching often uses implements such as a foam roller to apply force to tender and sore areas of the body
Which of these is not a main goal of plyometric training?
Increase maximal heart rate
Enhance neuromuscular efficiency
Increase rate of force production
Improve functional eccentric strength
Increasing maximal heart rate is not one of the main goals of plyometric training which mostly focuses on developing explosive and quick movement
Which of these is not a benefit of a warm-up?
Direct hypertrophy of the muscles that are warmed up
Increased heart and respiratory rate
Increased tissue temperature
Increased psychological preparation
Hypertrophy, the building of muscles, is not a goal of warm-up; a warm-up is used to increase heart rate and temperature to provide an effective transition into exercise
