Common parkour vaulting techniques, landing styles, and their effects on landing forces

Abstract

The emerging sport of parkour has developed a landing technique focused on soft, quiet landings. The proficiency of traceurs for two-legged drop landing tasks is becoming increasingly established, but it is unknown whether the same aptitude will be demonstrated for different movements with different landing techniques. This poster investigates the ground reaction forces (GRFs) produced by three common parkour vault techniques and a drop, using two common landing styles, to assess the potential injury implications of choosing one movement or landing style over another. This poster was produced after the abstract for my dissertation, 'Common parkour vaulting techniques, landing styles, and their effects on landing forces', was accepted for poster presentation at the BASES Conference 2021.

References
Movement and landing style choice affect GRFs for common parkour vaulting techniques. While vGRFs increased in
running style landings, they still did not exceed those typically experienced in jogging (3-4 x BW), indicating that
traceurs mimic their performance in two-legged drop landings and continue to effectively mitigate vGRFs when
vaulting. Consequently traceurs are unlikely to be at risk of acute lower limb injury when vaulting, but may remain at
risk of chronic lower limb injury with high repetitions.
Conclusions
Results
Heaviest Vault
Kong
Heaviest Landing
Style
Running
Lightest Vault
Dash
A signicant interaction effect between movement choice and landing style was
found for both peak vGRF (p= 0.01) and peak bGRF (p< 0.01). All movements
increased in peak vGRF with a running landing, while only the drop and kong vault
increased in peak bGRF. The kong vault produced the greatest peak vGRF and
bGRF in both landing styles, while the dash vault produced the least. The step
vault did not signicantly differ from a drop landing with either landing style.
Method
10 traceurs (age 29.4 ± 7.2 yr, height
173.8 ± 8.1 cm, weight 74.2 ± 8.4 kg,
experience 9.7 ± 3.6 yr) performed a
drop landing, step vault, dash vault,
and kong vault onto a force plate
with a two-legged precision landing
(precision) and a single-legged
running landing (running). Peak
vertical (vGRF) and braking (bGRF)
GRFs per limb were analysed by
repeated-measures two-way ANOVA.
Investigate the ground reaction forces (GRFs)
produced by three common parkour vault techniques
and a drop, using two common landing styles, to
assess the potential injury implications of choosing one
movement or landing style over another.
Aim
Background
The emerging sport of parkour has developed a
landing technique focused on soft, quiet landings. The
prociency of traceurs for two-legged drop landing
tasks is becoming increasingly established (Puddle and
Maulder, 2013), but it is unknown whether the same
aptitude will be demonstrated for different movements
with different landing techniques.
