Ace Chapter 9 Review Questions

QuestionAnswer
Which of the following joints is classified as favoring stability over mobility? Scapulothoracic
A lack of hip joint mobility is BEST likely to lead to which of the following? Compromised stability in the knees and lumbar spine.
Limited movement over an extended period of time can result in muscle shortening on one side of a joint and muscle lengthening on the other side of the joint. How do these length changes affect the force generating capacity of these muscles? They will have greater force-generating capacity at their new lengths, but diminished force-generating capacity at normal resting lengths.
Which force couple creates posterior rotation to pull the pelvis out of the anterior pelvic tilt? Hamstrings and rectus abdominis.
The middle layer of torso muscles that are commonly referred to as "the core" consists of the ___. Multifidi, quadratus lumborum, transvers abdominis, deep firbers of the internal oblique, diaphtagm, and pelvic floor musculature.
Once a client can perform two sets of 10 repetitions of glute bridges, which exercise would provide the MOST appropriate progression? Single-leg glute bridge with opposite knee to chest.
When helping a client build scapulothoracic stability, which exercise should a trainer have him or her perform FIRST to teach the client how to "pack" the scapula? Supine shoulder depression and shoulder retraction
Once a client can demonstrate good static balance while standing on two feet, what exercise could the trainer introduce that would provide the MOST appropriate progression? Narrowing of the base of support
Which progression follows the part-to-whole teaching strategy in helping a client learn proper technique for the bend-and-lift squatting movement? Hip hinge, lower extremity alignment, figure-4 position.
Once a client demonstrates good form while performing kneeling wood-chop spiral patterns with short and long movement arms, what exercise would provide the MOST appropriate progression? Standing wood-chop spiral patterns with short moment arms.
Muscles have been shown to shorten when help passively in shortened positions in as few as ___. Two to four weeks
Which of the following neuromuscular principles occurs when the activation of a muscle on one side of a joint coincides with neural inhibition of the opposing muscle on the other side of the joint? Reciprocal inhibition
Which muscle group is primarily responsible for the "hoop tension" effect during core stabilization techniques? Transverse abdominis
Which of the following joints favors stability over mobility? Knee
Which of the following muscles exerts an upward pull on the anterior, inferior surface of the pelvis in an effort to maintain a neutral pelvic position? Rectus Abdominis
When trying to meet the objective of the stability and mobility training phase by reestablishing appropriate levels of stability and mobility through the kinetic chain, a personal trainer should begin by targeting which region of the body? Lumbar Spine
After proximal stability is established in the lumbar spine, the focus of the stability and mobility training phase shifts to establishing _______________. Mobility of the pelvis and thoracic spine
Which stretching technique is MOST appropriate for deconditioned clients to perform DURING a workout? Dynamic stretching
A skilled performance athlete who has established good flexibility would like to address functional flexibility during his pre-exercise stretching routine. What two types of stretching would be the BEST choices for this client? Dynamic stretching and ballistic stretching
Which of the following muscles is part of the outer layer of the core? Latissimus dorsi
The strengthening of weakened muscles should begin with the performance of two to four repetitions of isometric muscle contractions, each held for five to 10 seconds at less than 50% of maximal voluntary contraction in a supported, isolated environment. True
A key role of the serratus anterior during open kinetic chain movement is to move the thorax toward a more fixed, stable scapulae. False
The center of mass is generally slightly lower in men due to their increased body mass and narrower stance. False
Which of the following techniques will reduce the balance challenge of an exercise? Lowering the center of mass
Standing on a single leg and taking a step mandates stability in each of the following regions EXCEPT the __________. Raised Leg
Which type of movement has the GREATEST need for thoracic mobility? Rotational Movements
Which of the following exercises BEST addresses the rotational movement pattern during the movement-training phase? Wood-chop
