BACKGROUND & OBJECTIVE
Rapid increases in training load from running is a contributing factor to many running-related injuries. This study investigated whether there would be a difference in injury rate between two groups using different running load progressions: one focusing on progressing intensity and the other volume.
447 healthy recreational runners (defined as people who ran 1-3 times per week for the past 6 months) were randomized into two groups: intensity and volume. Each group performed the same eight-week training program and then performed different programs for the next 16 weeks.
The intensity group increased the weekly volume of running at a â€œhardâ€ pace (VO2max above 88%.) The volume group increased the total running volume at an â€œeasyâ€ pace (VO2max below 80%).
Both groups ran three times per week in a program that was periodised into 4-week blocks with structured progression/regression. In the first week in each block, weekly running volume would progress 23%, and in the last week running would regress 10%.
Despite the differences in the training programs, the injury rates between the two groups were not significantly different.
