Body Types
Name the 3 body types we discussed last week
mesomorph,ectopmorphs, and endomorphs
Type I muscle fibers are _____ twitch
slow
When training an endomorph, what is usually the primary focus?
________ respiration, which uses oxygen to produce energy.
aerobic
Type IIX muscle fibers are _____ twitch
fast
Who usually has medium bone structure and athletic musculature body type.
Mesomorph
Type I fibers are often associated with this category of sports
endurance
Which body type is most likely to benefit from nutritional protein shakes?
Ectomorph
During resistance training, lifting lighter loads and performing higher repetitions primarily trains which type of muscle fibers?
Type I (Slow twitch)
What color are most slow twitch fibers
Red
Who is characterized by narrow shoulders and hips, relatively smaller muscles, with a fast metabolism that makes it difficult to gain mass.
ectomorph
This muscle fiber type fatigues very qucik
type II (fast)
What training approach is suggested for mesomorphs?
power-lifting and sport-specific training
Strength or power training mostly trains which muscle fiber type?
Type II (fast- twittch)
Slow fibers have large _______ reserves
Mitochondria
Is it true that Dr. W.H. Sheldon theorized the concept of somatotypes in the early 1840.
False
Type II fibers have most beneficial for speed and P _ _ _ _ _ .
power
Which somatotype is associated with a naturally fast metabolism?
Ectomorph
Describe a muscle fiber
Muscle cells that help the body perform specific physical functions.
Which type has the quickest reaction speed? Type IIA or Type IIB
Type IIB
Which somatotype is associated with a naturally fast metabolism
Ectomorph
What is it called when training adapts to use both fiber types?
Hybrid
what is the primary factor influencing body composition changes over time?
consistent diet and exercise
O _ _ _ _ _ _ _ capacity refers to how much oxygen a gram of muscle can use in an hour.
Oxidative
