  Purpose

The goal of this project is to understand the effect of regular practice of long distance running on the posture and movement control of older adults.

For such, the investigators will conduct an experiment with longitudinal design where sedentary elderly individuals will be trained in long distance running for about 4 months.

Primary Outcome Measures:
  • Change from baseline of posture and movement patterns at 16 weeks [ Time Frame: Two weeks before and two weeks after the training for sixteen months ] [ Designated as safety issue: No ]
    biomechanical and physiological measures of the posture and movement patterns


Secondary Outcome Measures:
  • Change from baseline of mechanical joint moments estimated by inverse dynamics at 16 weeks [ Time Frame: Two weeks before and two weeks after the training for four months ] [ Designated as safety issue: No ]
    Estimated joint moments by inverse dynamics at the ankle, knee, and hip joints during the support phase of walking and running

  • Change from baseline of muscle activity measured by surface electromyography of selected muscles of the lower limb at 16 weeks [ Time Frame: Two weeks before and two weeks after the training for four months ] [ Designated as safety issue: No ]
    Electromyographic activity of lower limb muscles during walking and running

  • Change from baseline of body sway measured by estabilography with a force plate during standing at 16 weeks [ Time Frame: Two weeks before and two weeks after the training for four months ] [ Designated as safety issue: No ]
    Measurements of balance control during quiet and unconstrained standing using a force platform.

Detailed Description:

In a study the investigators conducted about elderly runners, the main observed difference by the first time was that elderly individuals present greater foot abduction (toe-out) during running than young adults. This alteration has been observed in elderly individuals in general during walking, and identified as a protective mechanism to not overload the medial compartment of the knee joint. It is also known that elderly individuals present a different joint torque distribution in the lower limbs during walking in comparison with young adults. However, it's not known the relation between the movement patterns, particularly the foot abduction pattern, and the mechanical load on the knee joint during running by elderly individuals and neither the longitudinal effect of running practice on this relation and on the mechanical joint load distribution. Another unknown aspect is the actual effect of the running practice on the posture control of elderly individuals.

With this project, the investigators want to understand why elderly individuals change their movement pattern during running, to determine for the same subjects if this altered pattern is also present during walking and standing, and to determine the effect of running practice on the elderly posture control. Our hypotheses are that the strategy of greater foot abduction is present in all movement tasks and that the use of this strategy is related to the integrity of the knee joint, even considering the highly active elderly individuals and that the practice of running contributes for a better postural control in this population.

These findings will contribute for a greater understanding of the benefits of the practice of running and the adaptations developed by the elderly runners and in this way to contribute for the prescription of this activity to the elderly population.
