Purified antibodies to the thick filament accessory proteins, C-protein, X-protein and H-protein, have been used to label fibres of three rabbit muscles, psoas (containing mainly fast white fibres), soleus (containing mainly slow red fibres) and plantaris (a muscle of mixed fibre type) and their location has been examined by electron microscopy. These(More)
OBJECTIVE To compare overground and treadmill running for differences in the three-dimensional angular kinematics of the lumbo-pelvic-hip complex. DESIGN A within-subject repeated measures design. BACKGROUND The treadmill is an attractive research instrument as speed and slope are easily controlled and the required calibration volume is reduced.(More)
The intra-subject repeatability of measuring the three dimensional (3D) angular kinematics of the lumbo-pelvic-hip complex during running was evaluated. Spatio-temporal parameters were found to be repeatable. All angular kinematic parameters displayed high within-day repeatability despite numerous potential sources of variability in the data. Most angular(More)
The locations of C-protein, H-protein and X-protein in rabbit psoas, plantaris and soleus muscles have been investigated with fluorescently tagged specific antibodies. Two systems have been examined: isolated myofibrils allowed the locations of these proteins within the sarcomere to be determined, while cryosections allowed a comparison of the amounts of(More)
The variability in the three dimensional (3D) lumbo-pelvic angular kinematic patterns during running when using differing Cardan angle sequences was quantified. Data for four able-bodied subjects running on a treadmill at 4.0 m/s were captured using a motion analysis system with six cameras operating at 200 Hz. The adjusted coefficient of multiple(More)
