Physical preparation and prevention

RUGBY TRAINING Reading time : 12 min Updated August 30, 2026
Physical preparation in rugby is collision preparation, and its centre of gravity is the head. Two truths this guide holds together, softening neither. First: after a concussion, return to play is a staged process governed by minimums — you do not guess a date. Second: the prevention programmes (Activate, neck strength) are worth doing, but the evidence is promising, not conclusive — the sport’s own biggest trial, on tackle height, came back null.
Graduated return-to-play ladder after concussion Six steps from rest to return to match play, each step at least 24 h: rest, light aerobic exercise, sport-specific exercise, non-contact training, full-contact training, return to play. Minimum stand-down 21 days for adults, 23 days for under-19s. 1 · Rest relative 2 · Aerobic light 3 · Specific running, no impact 4 · Non-contact training 5 · Contact full training 6 · Return to play ≥ 24 h / step

Graduated return to play after concussion — World Rugby (GRTP), Paak protocol CONC-001: 6 steps, at least 24 h each; minimum stand-down 21 days (adult) / 23 days (under-19).

Graduated return-to-play (GRTP)

Concussion in rugby follows a common framework, World Rugby’s graduated return-to-play (GRTP), which Paak encodes as protocol CONC-001. The starting rule has no exception: a player with a suspected concussion is removed and does not return the same day. Recovery then follows a staged, symptom-limited progression, with a minimum time per stage and medical clearance required before contact and before return to play.

The number of steps and the 24 h minimum set a floor, not a calendar: six steps, each at least 24 h, with two medical locks. On top of that floor, World Rugby sets a minimum stand-down of 21 days for adults and 23 days for under-19s — youth and community-game timeframes are more conservative than the elite. Those are the figures carried by the ladder above and by protocol CONC-001.

Return is never a single number. The earliest return date is computed from the incident date, the age and — in France — the number of concussions. So a club must not display “X days” as a constant: it is a computed date, and a minimum, not a target.

The carton bleu and the FFR timelines

In France, the FFR layers onto the GRTP an age-differentiated medical protocol built around the carton bleu (blue card): a match official removes a player with a suspected concussion. The blue card triggers a mandatory medical pathway before any return, and Paak treats it as a first-class event. The timelines below are minimums, not targets.

Age group1st concussion — earliest return2nd concussion3rd concussion
Under 19day 23day 42 + specialist opinionday 180
19 and overday 21+ specialist opinionday 90

Notice the consistency with the GRTP: World Rugby’s minimum stand-down — 21 days adult, 23 days under-19 — matches the FFR minimums for a first concussion exactly. France tightens from the second onward, requiring a specialist opinion, up to 90 days (adult) and 180 days (under-19) at the third. The carton bleu also imposes an initial rest period before any return; the exact number of hours should be read off the current-season FFR form, as the public documentation is not perfectly unambiguous on that point — but it does not change the return minimums above.

This schedule is specific to France. Outside France, with no confirmed national protocol — for Switzerland (FSR), Germany (Rugby Deutschland), Austria (ÖRV) — you apply World Rugby’s GRTP (the six steps, 24 h, 21 / 23 days). Never present the FFR days as the rule in another market.

Prevention: Activate

Rugby’s reference prevention programme is called Activate: a structured, exercise-based warm-up (balance, whole-body strength, agility, and a neck-activation block), with age-banded versions — U13-U15, U16-U18, and adult / community. In the corpus, the associated form is rug-activate-prep.

Activate is a foreign programme. It is published by the RFU / World Rugby (an English curriculum), and not by the FFR or the Swiss FSR. You may take inspiration from it, but cite it for what it is: imported content, to be checked against national protocols where they exist.

What the evidence says. Movement-control warm-ups of this family have exposure- and injury-behaviour evidence in rugby, and strong evidence in other sports. But their effect depends on consistent, dosed use, not one-off application: an Activate done occasionally does not protect. That is the guide’s first piece of honesty — the programme is recommended, provided it is kept up over time.

The neck and the trunk

Neck strength is a rugby-specific focus, because the neck is in the front line of the tackle and the scrum. The corpus trains light isometric neck conditioning with the form rug-gainage-cou, presented as collision preparation, kept light and age-appropriate, and marked rung 3 (the exercise exists in coach education, but no federation fiche dates it by youth band).

Does the neck prevent concussion? Promising, not conclusive. Neck strength is a candidate protective factor for head and neck loading in the tackle and the scrum. The evidence for concussion prevention specifically is promising but not conclusive: it is recommended as collision preparation, not sold as a guarantee.

Being honest about the evidence: tackle height

The tackle is rugby’s single most injurious phase, which is why the tackle-height law has been actively changed — and studied. From 1 July 2026, in the World Rugby community game, the legal tackle height is set by the match organiser, who chooses the waist or the base of the sternum; the elite game keeps the shoulder line.

Lowering the tackle line is not proven to cut concussion. The key trial is a null. The RFU community-game lowered-tackle-height trial (Stokes et al., BJSM, 2021) found no statistically significant reduction in concussion: the head-injury rate ratio was about RR 1.31 (95% CI 0.85–2.01) — the confidence interval crosses 1, i.e. not significant — and, strikingly, tacklers were concussed at a higher rate (about RR 1.90). The trial was ended early.

How to read it. Lowering the tackle line is plausible but unproven as a concussion-reduction measure; it also shifts risk toward the tackler (a lower body position brings the head closer to the hips and knees). The law is a risk-management choice under uncertainty, not a settled fix. Two instructions follow: never present tackle-height lowering as proven to cut concussion; and do not cite the superseded 2019 “armpit” trial. The low-tackle technique itself is covered in Tackling & the breakdown.

What hurts players, and how often

Epidemiology figures are counted in injuries per 1000 player-match-hours. At the 2019 World Cup (analysis in SAJSM 32(1)), the overall rate was about 79.4 / 1000 match-hours, the tackle accounted for about 47.8% of injuries, and concussion sat at about 12.2 / 1000 (reported not significantly different from previous events).

  • The tackle causes roughly half of all injuries — hence the weight the whole corpus puts on tackle technique and head placement.
  • Concussion is the most-reported single diagnosis at elite level (English PRISP surveillance; Rugby Europe development data, tackle-dominant).
  • Rates rise with age and level: youth rugby is far lower-incidence than the professional game — which is exactly why contact is layered on gradually.
These figures are elite figures. The 2019 World Cup is professional men’s rugby — not a benchmark for a youth club. They are used to justify a direction (the emphasis on the tackle, the gradual build-up of contact), never to set a numeric expectation for young players.

Collision load

In rugby it is not only running load that counts: it is collision load. Total contacts — tackles, rucks, scrums — are the driver of fatigue and risk. So monitor contact volume alongside distance and intensity, not distance alone.

Physical development follows maturity. Strength work is bodyweight-based for the youngest bands, then progresses to loaded work with maturity. The corpus sorts this thread onto three forms of rising demand: rug-motricite-ballon (movement), then rug-activate-prep (Activate), then rug-gainage-cou (neck and trunk).

Frequently asked questions

After a concussion, what is the minimum before playing again?
No same-day return. Recovery follows graduated return-to-play: six steps, at least 24 h each, with medical clearance before contact and before return. Minimum stand-down is 21 days (adult) and 23 days (under-19) for a first concussion, rising to 90 / 180 days at the third under the FFR schedule — these are computed minimums, not a single number.
Does lowering the tackle line cut concussion?
It is not proven. The RFU trial (Stokes et al., BJSM 2021) is a null: no significant reduction (RR ≈ 1.31, CI 0.85–2.01 crossing 1), and a higher rate among tacklers (≈ 1.90); the trial was ended early. The law is a precaution, not a settled fix.
Is Activate published by the FFR?
No. Activate is an RFU / World Rugby curriculum (foreign), not an FFR or FSR publication. Outside France, until a national protocol is confirmed, you apply World Rugby’s GRTP; the carton bleu schedule is specific to France.
Does neck strength prevent concussion?
It is promising but not conclusive. It is recommended as collision preparation, kept light and age-appropriate (rung 3), without being presented as a guarantee against concussion.
