bridges attached and hence greater tension is developed. >>
***Yes, studies seem to confirm this information on cross-bridging
efficiency, but we are still left with the problem that the highest levels of
tension in the muscle complex occur during explosive rebound movements or
rapidly terminated eccentric actions which apparently do not provide adequate
time for optimal cross bridging. How do we explain this apparent paradox?
