Up & Down: Increased vertical oscillation
⬆️⬆️ 𝐔𝐏 & 𝐃𝐎𝗪𝐍 ⬇️⬇️
Are you a runner that can be heard a mile away pounding the pavement? Chances are, you may possess an increased vertical oscillation.
From the research, we know those with an increased vertical oscillation can experience:
🔹Increased peak knee extensor moment, peak vertical ground reaction force and braking impulse (Wille 2014, Napier 2018)
🔸Increased vertical displacement has been associated with low running economy (Moore 2016, Folland et al. 2017)
🔹Increased knee extensor moment, increased peak vertical GRF, increased AP GRF (Heiderscheit et al. 2011)
Runners that have excessive vertical oscillation can often be heard with a heavy landing. They also tend to display overstriding and a low cadence. At toe off they possess an angle of propulsion too vertical, which results in an increased vertical movement rather than a more preferable horizontal propulsion.
Firstly to measure this displacement we can take a line through the pelvis at the highest point during the flight phase, and then a line at the lowest point during mid-stance.
How to address this (if you need!)
The two most common cues to help with this include:
🔹Increasing cadence (Heiderscheit 2011)
🔸Cueing a lighter landing
