Propping up rugby’s front row

The front row in rugby union is not for the faint of heart.

Watch any Six Nations match and look at what goes on between the sets of props and hookers. Immense power, scrumming technique, and gamesmanship create a kind of magic you won’t find anywhere else on the field.

However, being a tighthead, loosehead or hooker takes an immense toll.

“The amount of force your neck and spine take in the front row is incredible,” says Ultra Sports clinic senior physiotherapist and former player Travis Masters.

“It's a controlled collision, with compression – often several times the bodyweight of a person – moving rapidly through the neck and spine. There is also sheer force pushing one vertebra forward or backward relative to the one below or above it.”

He adds that flexion and rotation often occur in an asymmetrical loading pattern.

As a result, the neck must stiffen to absorb and transfer force, maintain alignment, and transmit power coming from the hips and legs. The neck is not working in isolation; rather, it is the top of a kinetic chain that includes the hips, trunk, lumbar, and thoracic spine.

“Then comes the sustained drive. There is prolonged isometric contraction of the muscles around the neck, namely the cervical extensors under compression. The thoracic spine is resisting collapse, while the lumbar spine is transferring force from the legs,” Travis explains.

“As fatigue sets in, sheer force increases and small technical faults are amplified, thereby increasing the risk of injury.”

Cervical spine issues are the most common type of injury based on scrum-engagement volume.

Thoracic and rib issues also occur because the thoracic spine is absorbing sustained compression loads during scrums, while binding, tackling volumes, and impact play frequently lead to shoulder problems.

It goes without saying that front-rowers risk concussion.

Fortunately, concussions are now better managed in the modern game thanks to strict guidelines on when a player may return to action and changes to the laws that have reduced engagement impact and head contact.

A multi-faceted approach looking at neck endurance, motor control, fatigue resistance, and technical precision is needed to prevent injuries. “We focus heavily on isometric endurance in neutral and slight flexion – controlled resisted rotation and progressive axial load tolerance.”

According to a recent review, incorporating cervical muscle strengthening into rugby training is associated with a 45% reduction in concussion incidents in male rugby players.

Physios will also focus on glute strength, trunk stiffness, and anti-rotation control since the cervical spine absorbs the compensatory load if front-rowers’ hips collapse.

“What can really change the long-term trajectory for front-row players is a combination of early intervention, smart load management, and whole-chain conditioning,” Travis says.
