What does NASM’s OPT model stand for?
NASM’s OPT model stands for Optimum Performance Training, which includes:
1. Stabilization Endurance
2. Strength Endurance
3. Hypertrophy
4. Maximal Strength
5. Power
What is the primary focus of the Stabilization Level of the OPT model?
The Stabilization Level focuses on improving muscular endurance, joint stability, posture, and neuromuscular efficiency.
What is homeostasis in the context of exercise physiology?
Homeostasis is the body’s ability to maintain a stable internal environment, even during exercise.
What are Type I muscle fibers known for?
Type I muscle fibers are slow-twitch fibers that are fatigue-resistant and specialized for endurance activities.
Which type of contraction occurs when a muscle lengthens while contracting?
Eccentric contraction.
What is the primary component of the extracellular matrix in bones?
Type I collagen (organic) and hydroxyapatite (inorganic).
Osteogenic cells develop into which type of bone cell, and what do these cells become when trapped in the bone matrix?
Osteogenic cells develop into osteoblasts, which, when trapped in the bone matrix, become osteocytes.
What is the function of osteoclasts in bone tissue?
Osteoclasts are responsible for bone resorption, breaking down bone tissue to release minerals like calcium.
What structure surrounds the bone’s outer surface where it is not covered by articular cartilage?
The periosteum.
What type of bone predominantly composes vertebral bodies?
Trabecular (spongy) bone, surrounded by a thin layer of compact bone.
What are the small spaces in bone that house osteocytes?
Lacunae.
If an 18-year-old has clear epiphyseal plates, are they likely to grow taller?
Yes, because the presence of epiphyseal plates indicates that the growth plates are still active.
