HPEX 310 CHAPTER 4 QUESTIONS WITH
VERIFIED ANSWERS 2025 - 2026
muscular strength ANS - ability of muscle to generate force
muscular endurance ANS - ability to generate force over and over
muscular functionality ANS - combination of strength and endurance
benefits of strength training ANS - reduces low back pain, joint/muscle injuries, increases resting energy
expenditure
how many skeletal muscles are in the body? ANS - 600
fascia ANS - dense layer of connective tissue surrounding muscle fibers
motor unit ANS - motor nerve and all the fibers it innervates
isotonic (dynamic exercise) ANS - movement of a body part at a joint
what are the two types of isotonic muscle movements? ANS - concentric: muscle shortens during
movement against resistance
eccentric: muscle lengthens during movement against resistance
isometric (static exercise) ANS - uses muscle tension but involves no movement
isokinetic ANS - application of force at a constant speed and direction (machine supplying resistance
through full range of motion)
slow twitch fibers (type 1) ANS - contract slowly, highly oxidative (aerobic)
