Chap 1-6 Flashcards
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
how to increase test
large mm groups
heavy resistence (85-95% 1rm)
mod (high volume)
Short rest (60-90sec)
How to increase GH`
high intensity (10rm or heavy)
3 sets
short rest (1 min)
can mm fibres change
transformation from type IIx to a (more aerobicaly resistent)
heavy resistence training changes
reduced mitochondrial density
reduced capillary density
increased buffering capacity
changes in mm substrate content + enzyme activity
what is MES and principals needed for change (4)
1/10 force required to snp bone
- mangnitude of load (intensity)
- Rate of loading
- direction of forces
- volume
how long do endocrine receptors get upreg after activtity
upregulate andrigen receptor content within 48-72 hours post workoit
chronic cardiovascular adaptations at rest from anerobic and resistence
anerobic= decreases or no change in resting HR+BP
Resistence- alters cardiac demensions
what intensity is peak power (lower/upper)
jump squar with loads 30-60% 1RM
Balistic bench 46-62% 1RM
acute changes to aerobic exercise
increases CO, SV, HR, O2 uptake, SBP, blood flow to active mm and DECrease in diastolic
