Kinesiology
The plane that divides the body into left and right halves
sagittal
A loss of more than this percentage of body mass via sweat can impair performance.
~2%
The physiological cause of exercise-induced hypotension post-exercise
peripheral vasodilation
fat soluble vitamin that is a powerful antioxidant, veg oils, green leafy vegetables, nuts, legumes
vitamin E
3.5 mL x kg(-1) x min(-1)=
1 MET
The muscle primarily responsible for producing a movement
agonist
ACSM recommends consuming fluids at this rate during prolonged exercise
~0.4-0.8 L per hour
The metabolic cause of exercise-induced acidosis
hydrogen ion accumulation
fat soluble vitamin, involved in blood clotting (anti-hemmorhagic vitamin), green leafy vegs, intestinal bacterial synthesis
vitamin K
sensory receptor; main function is to respond to stretch of a muscle and initiate a stronger muscle action to reduce this stretch
muscle spindle
A lever where the axis is between the force and resistance
first-class lever
Monitoring changes in this variable is a practical way to assess hydration status
body mass
What is the threshold for an action potential
-55 mV
vitamin, oxidation of carbs, eye function, healthy skin, milk, liver, whole grains
Riboflavin (b2)
this training strategy of planned cycles can overcome strength plateaus
periodization
The phase of gait where the foot is off the ground
swing phase
In athletes, prolonged low energy availability may lead to this syndrome
RED-S (Relative Energy Deficiency in Sport)
A post exercise phenomenon related to muscle creatine phosphate and oxygen restoration
excess post-exercise oxygen consumption (EPOC), oxygen debt
mineral that is the structure of bones and teeth, part of DNA, RNA and ATP, meats, cereals, grains, dairy products
phosphorus
the heart valve between left atrium and left ventricle
mitral valve
the sum of force and moment arm
torque
The principle governing adaptation magnitude
overload
Which ion is essential for triggering muscle contraction?
calcium (Ca²⁺)
What amino acids cannot be made by the body. As a result, they must come from food
essential
What is the term for the delay between a muscle action potential and the start of contraction?
latent period
