Personal Trainer Flashcards

Which of the following best describes the overload principle?

Answer: Progressively increasing training stress beyond what the body is accustomed to

The overload principle states that the body must be subjected to a greater stress than it is accustomed to in order to elicit a training adaptation.

Which muscle is the primary hip extensor during a conventional deadlift?

Answer: Gluteus maximus

The gluteus maximus is the primary hip extensor and contributes significantly to the hip extension force required to complete a deadlift.

What does RPE stand for, and what scale is most commonly used in fitness settings?

Answer: Rate of Perceived Exertion; Borg 6–20 scale

RPE stands for Rate of Perceived Exertion; the Borg 6–20 scale is the original and most validated scale used in exercise science and fitness settings.

A new client has a BMI of 32 and no diagnosed medical conditions. According to ACSM/NSCA preparticipation screening, this client is classified as:

Answer: Moderate risk due to BMI alone

BMI ≥ 30 is considered a positive cardiovascular risk factor; combined with age/sex considerations, this client may be classified as moderate risk and may benefit from medical clearance before vigorous exercise.

Which of the following is an example of an open kinetic chain exercise for the lower extremity?

Answer: Seated leg extension

A seated leg extension is an open kinetic chain exercise because the distal segment (foot) is free to move, allowing isolated quadriceps activation.

What physiological adaptation primarily explains the strength gains observed in the first 4–6 weeks of resistance training for beginners?

Answer: Neural adaptations and improved motor unit recruitment

Early strength gains in beginners are driven primarily by neural adaptations, including improved motor unit recruitment, synchronization, and reduced antagonist co-activation.

A client's blood pressure reading is 145/95 mmHg on two separate occasions. How should the trainer proceed?

Answer: Refer the client to a physician before continuing exercise

Stage 1 hypertension (≥130/80 mmHg) warrants a physician referral prior to beginning or continuing a vigorous exercise program.
