Running-related injuries in recreational runners remain a significant reason to discontinue participation, with potential effects on health and well-being.
Epidemiological and biomechanical studies have traditionally associated injuries such as Achilles Tendinopathy, Plantar Fasciitis, and calf muscle injuries with increases in running intensity; the same has been said about Patellofemoral pain, Iliotibial Band Syndrome, and Patellar Tendinopathy and increases in running volume.
In this study, these injuries were hypothesized to be associated with each running parameter. A sample of 231 recreational runners was randomised to either volume-based or intensity-based progressive running schedules. At least 80% of the running sessions had to be completed. Standardized diagnostic criteria were used for each injury across the entire follow-up period.
