Escape performance variables examined were: maximum instantaneous velocity (usually during stage 1 of the C-start), maximum instantaneous velocity during the propulsive tail stroke (stage 2), average velocity throughout the behavior, distance traveled during the behavior, time taken to complete the behavior, and time taken to reach the absolute maximum velocity (a measure of average acceleration).
Mean recruitment was at least 50% of maximum EMG for the soleus, gastrocnemius, hamstring, vastus medialis/lateralis, rectus femoris and gluteus maximus muscles during the propulsive phase (limb extension) and tibialis anterior muscle during the recovery phase (limb flexion) [ 25].
To augment resultant force, which affects swimmer's propulsion, the swimmer should concentrate in effectively optimising achievable hand areas during crucial propulsive phases.
A passive, slow return of the bell to its expanded shape is effected largely by the elasticity of the mesoglea layer, which crumples during the propulsive contraction.
Anyone accustomed to Mr. Maazel's seeming detachment during recent seasons with the New York Philharmonic would have been amazed by the sheer vitality he mustered to lunge and jab exacting cues during a propulsive account of Beethoven's Symphony No. 7. A youthful buzz also permeates Castleton's opera productions, but tempered with sophistication.
The shoulder flexors, adductors, and external rotators generated the largest moments in the sagittal, frontal, and transverse planes, respectively, during the propulsive phase of the cycle.
Main Outcome Measures: Kinetic information from the instrumented pushrim and kinematic information from a 10-camera motion analysis system were used to calculate seated elbow angle and mean peak sagittal, frontal, and transverse plane internal shoulder joint moments during the propulsive phase.
The audience mirrored the band's reserve; even during the most propulsive numbers, people seemed to remember that they were in a museum.
The start of the behavior was chosen as when the fish first began to bend into a "C" shape, and the end was defined as the instant when the tail, during its first propulsive stroke, passed through the midline of the body [16].
The limbs of quadrupeds, however, are more homogeneous, both pairs having a propulsive function during running.
