Important Info Flashcards
Davis Law
States that soft tissue molds along a line of stress
Altered reciprocal inhibition
Overactive agonist muscle decreases neural drive to a functional antagonist muscle
Sliding filament theory
Muscle contraction involving actin & myosin sliding past one another shortening muscle during concentric muscle action
Intrinsic motivation
you feel a sense of satisfaction, belonging. (feeling happy)
All-or-nothing principle
Motor units cant vary amount of force they generate, they either contact maximally or not at all
Length-tension relationship - resting length if a muscle and the tension it can produce at this
length, AKA relationship between actin & myosin (myosin is the larger myofilament)
Resting length if a muscle and the tension it can produce at this length, AKA relationship between actin & myosin (myosin is the larger myofiliment)
Principle
of specificity
states that the body will adapt to specific demands that are placed on it
Neuromuscular specificity
refers to speed of contraction & exercise selection
Mechanical specificity
refers to weight and movement placed on the body
Type I muscle fibers
Slow twitch
marathon runner
aerobic / fat utilization
Type II muscle fibers
Fast Twitch
Sprinter
carbs
Bio Energetics
Phosphagen = high intense / explosive with long recovery (when creatin is used)
Glycolsis = middle (mod intensity)
Oxidation - low intense / short rest period
