Default Aging and Distance per Stroke

HI Guys,

This research may be of interest and very TI orientated.

The research published inthe European Journal of Applied Physiology looked at swimming efficiency measures including the energy cost (energy used) of swimming, stroke frequency and distance per stroke, as well as measuring factors affecting resistance to moving through the water. They looked at these factors in 47 male masters swimmers aged 31-85 years of age.

What did they find

Stroke frequency (strokes per 25m) was no different between any age group. However, distance per stroke dropped steadily with age from 2.3m in the youngsters (30-40 years) to 1.6m in the 70-80 years age group. The message is clear. The older we become the more we need to focus on technique, and especially distance per stroke.
