Cycling strategies of young and older cyclists.

This study concentrates on the cycling strategies of older cyclists (54-62year olds) in comparison to young cyclists (20-30year olds). While cycling in a safe laboratory set-up, controlled lateral perturbations are applied to the rear of the bicycle. Three possible strategies to keep balance are analysed for a young and older aged group: steering, lateral trunk movement and outward knee movement.

Can vertebral density changes be explained by intervertebral disc degeneration?

One of the major problems facing the elderly spine is the occurrence of vertebral fractures due to low bone mass. Although typically attributed to osteoporosis, disc degeneration has also been suggested to play a role in vertebral fractures. Existing bone adaptation theories and simulations may explain the biomechanical pathway from a degenerated disc to an increased fracture risk.
