Plyometrics: What Muscles Do Plyometrics Work?


what muscles do plyometrics work today we
want to talk about what muscles do plyometrics work which muscle groups react favorably to
plyometric training and the reason why what muscles do plyometrics work first and
foremost I usually don’t think about muscles I think more about movement and there is a
wise guy his name is name is his one of the early strength and conditioning
coaches he said i think movement not muscles and i can fully relate to that comment because
in sports it’s not so much about isolated muscles it’s more about the muscle chain and
the movement resulting from that muscle change so let me explain that for example if we are
interested in jumping then there is a chain of muscles that is active in order to jump
so that could be for example the hip the gluts the quadriceps and the calves as a very simple
example so it’s not one muscle that works It’s a chain of muscles that work so what
muscles work or what muscle chain works is dependent on the exercise you choose so if
you choose to jump as i just explained then we have the muscle chain of cobs quadriceps
and gluts that is for the triple extension extension of the ankle extension of the knee
and extension of the hip If we’re looking at an upper body plyometrics then the muscles
of this muscle chain works off we thinking for example medicine ball chest pass then
we have the muscle chain consisting of the (inaudible) the chest muscle the deltoid the
shoulder muscles to triceps the muscle that is responsible for extending the arm so it’s
more thinking about a muscle chain that works rather than one muscle in isolation generally
speaking plyometrics work better for muscle are muscle chains that are (inaudible) muscles
rather than pulling muscles let me explain what i mean so an (inaudible) muscle for example
the same example of the jump go down the muscles extending into a jump these are (inaudible)
muscles the same as i said for the chest pass these also (inaudible) a muscle to extend
the arm for example It works better for these muscles because they work more in an eccentric
concentric fashion I’ve explained that in previous video we have eccentric contraction
and concentric contraction so if we’re standing upright and we descend the muscles work eccentrically
and then concentrically the same as for the chest pass we started that position with the
arms extended are similar to a bench press the muscles work eccentrically in the first
part of the movement they get lengthened and concentrically they get shortened so they
work in an eccentric concentric fashion if we think about pulling muscles for example
something like the vertical pull or horizontal pull so a vertical pull could be a chin up
or a pull up the muscles work in a concentric eccentric fashion so it’s different so the
plyometrics work better for movements that are working in eccentric concentric fashion
rather than a concentric eccentric fashion for the simplicity of the old principle about
plyometrics is eccentrically stretched and then this eccentric stretch is used for the
concentric unloading so as a recap think movement not muscles or at least think in muscle chains
not in isolated muscles for plyometrics the muscles or muscle chains that are worked depend
on the activity and generally speaking plyometrics work better for (inaudible) muscles that work
in an eccentric concentric fashion
