|---|---|---|---|---|---|
| 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
🗑
