Anatomically asymmetrical runners move more asymmetrically at the same metabolic cost.

Abstract: We hypothesized that, as occurring in cars, body structural asymmetries could generate asymmetry in the kinematics/dynamics of locomotion, ending up in a higher metabolic cost of transport, i.e. more 'fuel' needed to travel a given distance. Previous studies found the asymmetries in horses' body negatively correlated with galloping performance. In this investigation, we analyzed anatomical differences between the left and right lower limbs as a whole by performing 3D cross-correlation of Magnetic Resonance Images of 19 male runners, clustered as Untrained Runners, Occasional Runners and Skilled Runners. Running kinematics of their body centre of mass were obtained from the body segments coordinates measured by a 3D motion capture system at incremental running velocities on a treadmill. A recent mathematical procedure quantified the asymmetry of the body centre of mass trajectory between the left and right steps. During the same sessions, runners' metabolic consumption was measured and the cost of transport was calculated. No correlations were found between anatomical/kinematic variables and the metabolic cost of transport, regardless of the training experience. However, anatomical symmetry significant correlated to the kinematic symmetry, and the most trained subjects showed the highest level of kinematic symmetry during running. Results suggest that despite the significant effects of anatomical asymmetry on kinematics, either those changes are too small to affect economy or some plastic compensation in the locomotor system mitigates the hypothesized change in energy expenditure of running.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The researchers explored whether anatomical asymmetry in humans leads to an increased metabolic cost — essentially, does being physically asymmetrical make running more exhausting. This was assessed by investigating the correlation between structural asymmetries and running kinematics/dynamics, and their relation to energy consumption during running. The research found no significant correlation between anatomical variation and energy expenditure, but did note that physical symmetry correlated with more symmetrical movement, particularly in highly trained runners.

Research Methodology

  • The research team started by hypothesizing that body structural asymmetries may result in asymmetrical locomotion, which could potentially increase the metabolic cost of running — essentially requiring more ‘fuel’ for the same distance. This is based on similar findings in studies of horse locomotion.
  • The anatomical differences between the left and right lower limbs were examined using magnetic resonance images (MRIs) from a group of 19 male runners. These were divided into three groups: untrained runners, occasional runners, and skilled runners.
  • Running kinematics were studied by observing and recording the movement of the runners’ bodies on a treadmill, focusing on the centre of mass. The body’s coordinates were measured using a 3D motion capture system, and a mathematical procedure was employed to quantify the symmetry of the body’s motion during running.
  • The metabolic consumption of the runners was measured in the same sessions, and the cost of transport — energy used relative to distance run — was calculated.

Findings and Implications

  • No significant correlation was found between anatomical and kinematic variables and the metabolic cost of running. This held true regardless of the runners’ training experience.
  • However, there was a significant correlation between anatomical symmetry and kinematic symmetry. The most trained subjects demonstrated the highest level of kinematic symmetry during running.
  • The research suggests that while anatomical asymmetry can affect running kinematics, it doesn’t noticeably impact the energy expenditure. Either the changes induced by asymmetry are too small to affect the cost of transport, or the locomotor system compensates for the differences to mitigate additional energy costs.
  • These results challenge the initial hypothesis, suggesting a more nuanced relationship between anatomical structure and running efficiency. It appears that training can minimize or control the impact of asymmetry on running dynamics.
