Missed Questions Flashcards
How does stimulation of the sympathetic system affect the conduction system of the heart?
Accelerates SA node depolarization, and thus speeds up contraction and HR.
Height of box for step ups?
12-18” (lifter’s leg should be 90 degrees when on the box)
What happens in the preparatory phase of periodization?
No competition - basic strength - strength endurance/hypertrophy
Do training programs have to be different for females vs males?
no
MOST important type of validity to be considered when evaluating the quality of a test?
Construct validity (how well a test actually measures what it is supposed to measure).
NOT face validity or content validity.
How much recovery time is allowed for muscular endurance resistance exercise?
Up to 30s. (higher loads, shorter rest)
Most popular dietary supplement consumed by young people in USA?
pre-workout ENERGY drinks
How many essential amino acids are there? List them.
9
histidine, isoleucine, leucine, lysine, methionine, phenylalinine, threonine, tryptophan, valine
What works to increase acceleration ability?
incline sprinting, sled tows (helps body find natural acceleration position)
Do spotters need to be able to handle the entire load?
no
Difference b/w essential and non-essential amino acids?
Essential amino acids must be consumed. Non-essential are synthesized within the body.
Defined augmented feedback
External feedback from coach or trainer (can be verbal or video) that can be used to immediately improve form, execution, or performance.
Anaerobic CAPACITY is quantified as maximal power output achieved during activity lasting how long? Anaerboic POWER?
30-90seconds for anaerobic capacity. Less than 10 seconds for anaerobic power.
How do you calculate glycemic load (GL)?
(Glycemic index of food (GI) x grams of carbohydrate per serving) / 100
What is a structural exercise?
A core exercise that loads the spine directly or indirectly. (e.g. overhead squat)
What phase of the power snatch are the knees flexed the most?
catch
What energy system is used during an all out sprint lasting 5 seconds? 6-30 seconds?
<5 s = phosphagen
6-30s = phosphagen + glycolytic
What is an example of a anabolic steroid?
stanozolol
Anavar
What muscle fibers are LEAST resistant to fatigue?
Type IIx
Series of reactions in which free fatty acids are broken down, resulting in Acetyl-CoA and hydrogen protons?
beta oxidation
How many vertebrae in C-T-L-S spine?
29
C=7
T=12
L=5
Sacral = 5
When an athlete works at an intensity of 65% of V02 Max or higher, what’s the body’s major source of energy?
Muscle glycogen
(liver glycogen is used for low intensity exercise)
A marathon runner requires a high amount of what?
liver glycogen
As exercise duration increases and glycogen stores are depleted, which process provides additional glucose for energy without ingesting any additional macronutrients?
gluconeogenesis = conversion of fat or protein into glucose
What type of training has the greatest effect on excess post exercise oxygen consumption (EPOC)?
Heavy resistance training above 80% 1RM for max reps
Anaerobic capacity is defined as maximal power output lasting how long?
30-90seconds
Type I muscle fiber characteristics
slow twitch
most resistant to fatigue
highest capacity for endurance
lowest capacity for power
Type IIx muscle fiber characteristics
fast twitch
least resistant to fatigue
lowest capacity for endurance
highest capacity for power
Type IIa muscle fiber characteristics
fast twitch
sit in the middle b/w I and IIx
more fatigue resistant than IIx
greater endurance than IIx but less than I
lower power production than IIx but greater than I
