neurological adaptations muscle fatigue genetic factors phycological factors alcohol
types of muscle contraction
isometric
isotonic
isokinetic
isotonic muscle contraction consist of
concentric …. muscle shortens
ecentric …. muscle lengthens
isokinetic consist of
constant angular velocity
the maximum force that a muscle can exert is during contracion is greater than each other in what order
eccentric
isometric
concentric
characteristics of isometric exercises
reduces blood flow to the body
causes a sudden increase in heart rate and blood pressure
it can deprive the body tissue of oxygen
according to the contraction of the muscles dynamic contraction can be divided into
concentric
eccentric
according to the changes in the resistance applied dynamic contractions can be divided into
isotonic
isokinetic
what is the main goal in concentric contractions
counter the force
what is the aim of the eccentric contraction
prevent the movement from happening suddenly
usually muscle activities occur by making what and what
isometric and concentric contractions reapetedly or together
why is the energy spent on eccentric contractions less than that of the concentric
it is due to the absence of atp
how many exercises should be done to train large muscle groups
8-10
types of strength training
calistenic
manual resistance
mechanical resistance
