More Aerobic Intervals

Some more aerobic intervals today with a female soccer player. She did 3 sets of 6 reps, 80% sprint the length of a soccer field.

The graph to the left shows the strong correlation between her sprint time and mean ground contact time (pearson = 0.725). Sprint time is generally faster with a longer mean ground contact time.

From this information it looks like this athlete has a tendency to 'jump' up into the air too much while sprinting. Next session I will cue her to try to not move up so high during her air times.
