Exercise Technique & Safety Flashcards

What exercise modification is appropriate for a client with low back pain during a bent-over row?

Answer: Use a single-arm supported dumbbell row to reduce spinal loading

A single-arm supported dumbbell row allows the non-working hand to support body weight, significantly reducing compressive forces on the lumbar spine.

Which stretching method involves contracting the target muscle before stretching it to achieve greater ROM?

Answer: PNF stretching

PNF (Proprioceptive Neuromuscular Facilitation) stretching uses a contract-relax sequence to activate the Golgi tendon organ, allowing greater muscle lengthening.

What is the primary concern when training pregnant clients?

Answer: Avoiding supine positions after the first trimester and monitoring intensity

After the first trimester, supine exercise can compress the vena cava, reducing cardiac output; moderate-intensity training must also be monitored carefully.

What should a trainer do if a client reports chest pain during an exercise session?

Answer: Immediately stop exercise, have the client rest, and call emergency services if needed

Chest pain during exercise is a serious warning sign that requires immediate cessation of activity, rest, assessment, and calling emergency services if symptoms persist.

What is the role of the Golgi tendon organ (GTO) in muscle function?

Answer: Sensing excessive muscle tension and causing muscle relaxation to protect tendons

The GTO senses excessive tendon tension and sends an inhibitory signal causing the muscle to relax, protecting the muscle and tendon from damage.

Which warm-up type is most recommended before dynamic activity like sports or strength training?

Answer: Dynamic warm-up with movement-based exercises

Dynamic warm-ups use active, controlled movements that raise body temperature, activate the neuromuscular system, and prepare movement patterns specific to the training session.
