Alteration to the surface cushion appears to be sufficient to produce subtle changes in stride characteristics.
These results support the idea that strengthening the hip extensors may improve stride characteristics in elderly individuals.
Main Outcome Measures: Maximal isokinetic torque in the sagittal plane of hip, knee, and ankle muscles; stride characteristics of speed, stride length, and cadence recorded during walking at a self-selected velocity.
Mean stride lengths at the walk (P < 0.05) and trot (P < 0.01) and carpal joint circumference (P < 0.01) were greater in the SD phase than the barefoot phases.
In comparison, the gait test produced only a small, albeit statistically significant, reduction in the mean stride length (94.55% of control).
Design: Simultaneous recording of stride characteristics and kinematic, kinetic, and intramuscular electromyographic data; paired t tests identified significant between-condition differences.
Objective: To examine the relation between certain lower extremity isokinetic muscle torque capabilities and selected stride characteristics for a group of elderly, sedentary men.
Regressions of data coded by posture (crouched vs. erect) reveal nonlinear patterns in metabolic cost, limb muscle mass, effective mechanical advantage, and stride characteristics.
Biomechanical changes to LBPPT running are not well defined and, in the case of stride characteristics, are inconsistent.
Results are also conflicting regarding stride characteristics while running on LBPPT [10, 12, 22, 26, 28, 29].
