The Journal of Sports Science and Medicine has published two studies, which were conducted in New Zealand by Damien Puddle of NZ Parkour and others, looking into the landing technique used in parkour, described as typically characterised by landing on the forefoot only.
The first was published in 2013 titled ‘Ground reaction forces and loading rates associated with parkour and traditional drop landing techniques’, and the second was published in 2015 titled ‘A Comparison of the Habitual Landing Strategies from Differing Drop Heights of Parkour Practitioners (Traceurs) and Recreationally Trained Individuals’. More recently, NZ Parkour posted two infographics summing up the findings:
- When compared to non-parkour landings (characterised by forefoot to heel landing), parkour landings (characterised by forefoot only landing) were found to be safer.
The full details of what counts as safer can be found in the full studies, both of which are free to view online.
