Isotonic maintains constant speed; isokinetic varies the speed
Isokinetic only trains the concentric phase; isotonic trains both phases
Question 16: Whose 1968 book shaped 50 years of fitness culture toward cardio at the expense of resistance training?
Dr. Doug McGuff
Dr. Kenneth Cooper (Aerobics, 1968)
Edward Deci
Hislop and Perrine
Question 17: Per Shailendra et al. (2022), at approximately what weekly resistance-training volume was the all-cause mortality reduction greatest?
30 minutes per week
~60 minutes per week (−27% mortality)
90 minutes per week
150+ minutes per week
Question 18: Which of the following is NOT one of the five documented reasons clients quit conventional fitness programmes?
Time barriers
Lack of perceived results
Equipment cost
Relational factors (weak coach-client connection)
Question 19: According to the meta-analysis cited in Lesson 1.1, how did eccentric loading compare to concentric loading in muscle cross-sectional area increase?
10.0% eccentric vs. 6.8% concentric
6.8% eccentric vs. 10.0% concentric
15% eccentric vs. 10% concentric
Equal increases for both phases
Question 20: What does Delayed Onset Muscle Soreness (DOMS) actually indicate, per Lesson 1.1?
Muscular damage that should be avoided in future sessions
An acute inflammatory response to eccentric-induced microstructural changes — evidence the intended stimulus occurred
A sign of dehydration during training
A sign of overtraining that requires a full rest week
Question 21: What are the three components of the "therapeutic alliance" described in Lesson 1.3?
Trust, empathy, and competence
Goal agreement, task agreement, and bond quality
Autonomy, competence, and relatedness
Rapport, reflection, and reinforcement
Question 22: Which intake question, per Lesson 1.3, is described as the most revealing of a client's true motivation?
"What made you reach out to us now?"
"What have you tried before?"
"What does success look like for you in 6 months?"
"How many times per week can you train?"
Question 23: Why is isokinetic loading specifically advantageous for rehabilitation clients, per Lesson 1.3?
It builds muscle faster than isotonic training
Resistance never exceeds the client's voluntary force output, eliminating the force peaks that stress healing tissue
It requires no coach supervision
It only loads the eccentric phase of the movement
Question 24: In Motivational Interviewing (Lesson 1.3), what is the purpose of "evoking change talk"?
To tell the client why they should change
To ask questions that invite the client to articulate their own reasons for change
To confront the client's resistance directly
To set the client's training schedule
Question 25: Per the Silver Senior clinical context in Lesson 1.3, what is the approximate 12-month mortality rate following a hip fracture in an older adult?
