What is the type of muscle called that operates involuntarily and is non-fatiguing? (Tip: located in the heart)
(a)
During a (a) contraction, muscles shorten whilst producing force. During the downward phase of a squat, the (b) contract eccentrically . The erector spinae acts as a (c) , preventing the back from bending forward, supporting the core.

Regular exercise will cause the following long-term aerobic adaptations to the muscular system.
Increased mitochondria, increased myoglobin and increased use of fat (as an energy source)
Increased mitochondria, reduced myoglobin and increased use of glycogen
Increased myoglobin, increased tolerance to lactate and increased stores of glycogen
