Types Of Contractions and training Flashcards
Concentric
Muscle shortens by overcoming resistance. Positive
Eccentric
Same muscle now lengthens from it concentric position. While still under tension. Negative
Isometric contraction
Muscle contracts creating tension yet does not result in any movement. Eg. Plank
Isokinetic contraction
Concentric concentric movement eg. Rehabilitation
Eccentric training
Negatives. Only muscle lengthening phase. Greater than 1RM
Strength curve accending
Heavy at top eg. Squat, bench, deadlift, shoulder press.
Strength curve decending
Most difficult at beginning eg. Upright row, leg curl, lat raise.
Strength curve bell shape
Strong in the middle eg. Bicep curl
5 components of fitness
Muscular strength Muscular endurance Flexibility Cardio Body composition
Karvonen formula
Target heart rate formula
220- age
Changed to crazy new formula
Interval training
High intensity shot period
1:3 work rest ratio to 1:6
3-4 sets per exercise
Anaerobic glycolytic system 30 secs to 2 minutes
Fartlek training
Aka speed play
Interval and regular distance training.
Sprint interval training
“Walk back sprinting”
Sprint then walk back
Anaerobic
High intensity interval training
Hiit aka hiie high intensity intermittent exercise sit sprint intervals training
Tabata
Anaerobic exercise with recovery periods
Cardiovascular exercise
Isotonic
Concentric and eccentric movement eg. Bicep curls
Bicep
Tricep
Back
Chest
Abs
Lower back
Shoulders
Chest back
Quads
Hamstring
Tibuialis anterior
Calf
Plyometrics
Sudden eccentric followed by
Amortization
Followed by
forceful concentric contraction of same muscles
Periodization
Changing intensity of work load to create results. Purpose is to reach maximum or peak performance at specific time
Pyramids
Primarily used for gaining strength aka light to heavy. Accending
Sometimes done heavy to light but make sure to warm up proper. Decending
Can be done light to heavy then back down heavy to light double progressive
One set to failure
Lift weight slow for 10-15 reps until failure
?add weight?
PNF
Proprioceptive
Neuromuscular
Facilitation
Calm to release muscle
Push
Chest shoulder triceps
Pull
Back biceps
Number of sets for big muscles
6
Number of sets for small muscles
3
Rest time for strength
% of 1rm
2 minutes
85%
Rest time for hypertrophy
% of 1 rm
30-130
70%-85%
Rest time for endurance
% of 1 rm
30 seconds
70% or lower
Tempo for general lifting
2 concentric 4 eccentric
Drop or strip set
Heavy weight to fatigue Take of weight Go to fatigue No rest 8-12 reps or till failure 2-3 drop sets Hypertrophy
Superset
Alternating muscle groups
Agonist antagonist
Biceps triceps 1 set
2 minutes rest after each set
Stacking flushing
2 or more exercises for same muscle groups in row
Aka pair set
Priority system
Perform exercises for major muscles goal early
Risk stratification categories
Low risk, moderate risk, high risk
Primary risk factors
Most significant influence on whether coronary heart disease will develop
Secondary risk factors
Some other unalterable factors that relate to the development of of CHD
Fitt principal
Frequency
Intensity
Time
Type
Aerobic
Using oxygen 2 minutes plus
Submaximal exertion
Thr 50-70% of max moderate
70-85% vigorous
Anaerobic
Not using oxygen
30sec - 2 mins
RPE scale
Rating of Perceived exertion
Borg scale used as visual to describe effort while training.
Fast twitch fibers
Muscle fibers that contract quickly, used for intensive short duration exercises eg. Weights, sprints red? Dark
Slow twitch fibers
Muscle fibers that contract slowly and is used in moderate intensity endurance exercises eg. Long distance running
Diastolic
When heart relaxes
Bottom smaller number
Systolic
When heart contracts
Top larger number
HDL
Happy cholesterol
40-59 normal
LDL
Lousy cholesterol
Less that 150
Normal total for both is 200
Normal heart rate
60-100
Normal glucose levels
70-174
Atp pcr system
1st system 1 enzyme reaction 30 seconds Anaerobic system High lactic acid Phospocreatine stores in muscles Atp to adp High intensity
Glycolytic system
2nd system 30 sec to 2 minutes 10-12 enzyme reactions Anaerobic 1 glucose = 2 atp Aka anaerobic glycolysis Aka lactic acid system Production of atp High intensity
Oxidative system
3rd system 2 mins and above Low intensity 124 enzyme reactions Sub cycles kreb cycle electronic transport chain 2 molecules hydrogen and oxygen = water
All 3 metabolic systems create
1 glucose = 38 atp
Cardiac output
The amount of blood pumped out of each ventricle each minute
Stroke volume
The volume of blood pumped out of the heart by the ventricles in one contraction
Agonist
The muscle that directly engages in an action.
Antagonist
The muscle that provides the opposing action. To the primary (agonist) muscle
