At the top of a lateral raise, a client holds the upper arm still at shoulder height. Bending the elbow brings the dumbbell closer to the shoulder and makes the hold easier. What explains the change?
Correct answer: A - The shorter external moment arm reduces the torque the shoulder must resist.
A rested lifter completes a near-maximal repetition in about three seconds. Which pathway can resynthesize ATP most rapidly to support this brief effort?
Correct answer: A - The phosphagen (ATP-phosphocreatine) pathway
The prescription is three sets of 8-12 repetitions, ending with about two good-form repetitions in reserve. Two consecutive sessions produce 12, 12, and 12 repetitions with approximately four repetitions in reserve. Technique and between-session recovery are good. Which load adjustment keeps the client on target?
Correct answer: D - Increase the load modestly, then reassess repetitions and effort.
After three weeks of resistance training, a novice lifts substantially more weight through the same range of motion. Muscle size has not changed detectably. The most likely major contributor to this early improvement is:
Correct answer: D - Improved motor-unit activation and coordination between muscles.
During a Romanian deadlift, a beginner keeps the bar close and the spine controlled until the bar passes the knees. Reaching the instructor's mid-shin finishing position requires the beginner to round the lower back; the movement is painless. How should the instructor adjust the exercise?
Correct answer: C - Shorten the descent so it ends before lumbar control is lost.
A suitcase carry is performed with a dumbbell hanging directly beside the right hip. The client walks with the trunk upright rather than leaning toward the weight. The principal trunk movement being resisted is:
Correct answer: D - Lateral flexion
Before a client uses a leg-extension machine, the instructor notices that the machine's rotational axis sits several centimeters in front of the client's knee joint. The selected load is light and the adjustment pins are secure. What needs correction first?
Correct answer: A - Reposition the seat or backrest to bring the knee closer to the machine's axis.
A client's push-up record shows 16 repetitions at baseline and 24 six weeks later. The first test used floor push-ups; the second used push-ups with the hands elevated on a bench. Both instructors counted complete repetitions. What can these scores establish?
Correct answer: B - The protocol change prevents a valid estimate of improvement.
An otherwise healthy 74-year-old wants to rise from a low sofa without using the armrests. The client walks comfortably and completes controlled, pain-free chair stands from a firm, higher seat, but needs arm support from a lower seat. Which starting approach most directly addresses the goal?
Correct answer: B - Practice controlled stands from the higher seat, lowering the seat as ability improves.
'I already get enough protein, so I do not need carbohydrate after lifting.' A recreational athlete makes this claim while discussing recovery between demanding training days. Which reply accurately distinguishes the two nutrients?
Correct answer: C - Protein provides amino acids for tissue repair; carbohydrate helps restore muscle glycogen.
