Chap 1-6 Flashcards
(33 cards)
which bands shorten with mm flexion
H and I zones
(H is just myosin, I is just actin, A is overlap)
How to train phosphogen and rest intervals
100% - exercise 5-10 sec 1:12-1:20 rest
Fast glycoloss and slow glycolosis, work time and rest intervals
Fast (75-90%) exercise 15-30 sec 1:3-1:5
slow 30-90%- 1-3 mins 1:3-1:4
Oxidative work and work to rest
20-30% >3 mins work 1:1-1:3
Test effects
-promotes GH response in pituitaty, effects neurotrans to change pro sturcture to produce more power
GH effects
causes hypertrophy of both tye ½ fibres
increase FA utalization
effects of cortisol
Carbs metabolisms
converts AA to carbs
increase w exercise-may be a sig of overtraining
inhibits pro synthesis
causes mm tissue remodeling
1st, 2nd, 3rd class lever and ex
1st- mm force and resistance on opposite sides of lever (tris)
2nd- muscle force + resistance on same side as lever (calf)
3rd- mm and restance on same side but resistance is further (biuceps)
force eq
mass x acceleration
strength equatipn
max force in a specific velocity
Power equations (2)
work/time
force x velocity
Work equations
force x distance
newtons x distance x reps
(newtone 4.48)
Rotational work
torque x angular displacement
resistance equation
gravity= mass * gravity acceleration (9.8m/s)
weight vs mass
weight dependent on gravity, mass is a constant
what is bracketing technique
do sport mvmts with more or less acceleration
What is fluid vs form drag
fluid- friction of fluid passing along skin
form- the way in ehivh a fluid pass0es against the front or rear of an object
type 11a/x vs type11b/bx
a/x- fast twitch aerobically resistanct
b/bx- fast twitch, fatiging
energy yielf from 1 blood glu and 1 mm glycogen
blood glu 2 atp
mm glycogen 3 atp
when does lactate threshold start in untrained and trained athletes
untrained 50-60% of max O2 uptake
trained 70-80% in trained
When is OBLA
4mmol/L
how much does CP depreleate during first 5-30 sec of HI activity
50-70%
how long does it take for complete resynthesis of ATP post activity
3-5mins
role of catecholamines
increase force production
increase mm contraction rate
increase BP
increase blood flow
augment secretion of other hormones
