right..the muscle can contract without shortening and it is called isometric contraction.
the muscle consists of muscular portions and the fibrous portion(tendons) and the fascia covering the muscle entirely.
in isometric contractions, the muscle contracts but the load opposes shortening, thus the tendinous portion lengthens. thus the muscle length remains the same.
hope u got the difference btwn contraction and shortening.

Yes, the actin and myosin filaments bind and apply tension, but it is not enough to overcome whatever opposing forces are acting on that muscle (like when you strain with all your might but can't lift something heavy) The muscle stays the same length but becomes tense, and like SAMI said is called and isometric (means same length) contraction as opposed to isotonic (contant tone, lenght shortens) or isolytic, in which the opposing force overpowers the muscle and causes it to lengthen.

I'm with Doug here. Contract = Shorten........

well no contraction= shortening but if only individual cells contract you wont see an actual shortening of the muscle but the individual cells will still shorten

Yes. That is called isometric contraction.
