FLEXIBILITY- PROGRAMMING + PNF PROTOCOLS Flashcards
submodalities of flexibility
static
dynamic
ballistic
PNF
when does each submodality of flexibility occur
ALL in general prep
but can happen during any phase
when in session- static
end of session
-want to cumulatively achieve at least 60 seconds total
when in session- dynamic
beginning of session as warmup
when in session- ballistic
beginning of workout AFTER warmup
-muscle is less pliable when cold
when in session- PNF
end of session BEFORE static
**know- what makes PNF different from other submodalities of flexibility
with PNF we see more acute increase in ROM than other submodalities
tempo for all PNF
-passive pre-stretch: 10-15 seconds, 4-5 pain
-contraction: 6-10 seconds at 25-100% MVC
-passive stretch: 10-15 seconds, 4-5 pain
autogenic inhibition
when GTOs are activating in the SAME muscle we are stretching
-aka- if we are doing a hamstring PNF stretch + we do hold-relax, we are causing autogenic inhibition by contracting our hamstrings + causing our GTOs to activate causing hamstrings muscle to relax
which muscle contraction causes autogenic inhibition
antagonist muscle contractions
which PNF protocols have autogenic inhibition
ALL
reciprocal inhibition
seen in PNF protocols “with agonist contraction”
which muscle contraction causes reciprocal inhibition
agonist muscle contraction
what causes reciprocal inhibition
caused by CNS
-just the facilitation of saying “this is contracting so relax the agonist muscle”
-NOT CAUSED BY GTOs
hold-relax is what type of contraction
isometric contraction of muscle being stretched
