Abstract

Objective: To investigate the stride pattern of different age groups of veteran runners in a marathon road race. Methods: This kinematic study investigated the stride pattern (stride length, stride period, velocity, stance time and non-stance time) for 151 runners (78 men aged up to 75-80, 73 women aged up to 60-64) at the 7 mile point.

Results: Significant declines for men with aging were found for mean stride length from 2.4 m at age 40-49 to 2.0 m at age 60+], velocity and non-stance time (p < 0.05), while stride period changed little. The findings indicate that older runners' lower velocities are associated with shorter strides while cadence changes little. However, when a statistical adjustment was made for the variation in runners' velocity it was found that older runners did not have a significantly shorter stride length at any given velocity.

Conclusion: While a shorter stride is the mechanical route by which older runners lose velocity, the shorter stride may not be the fundamental cause of the velocity reduction with age. This has implications for researchers and coaches when investigating and training veteran distance runners.
