Fingers, growth and physical preparation

CLIMBING TRAINING Reading time : 12 min Updated October 28, 2026
Contents
In the young climber, the injury that matters is the stress fracture of the growth plate of the finger. It is concentrated between 13 and 15, in 98% of cases at the middle finger joint, and comes from repeated loading, above all in the crimp grip and on the campus board. The written rule is the BMC's, approved by the UIAA Medical Commission: no campusing before 18. For the rest, one thing is established: no injury-prevention exercise programme has been proven in climbers, and none has been tested in under-18s. This guide says what the research supports, and nothing more.

The growth plate of the finger, between 13 and 15

The growth plate of the finger receives a concentrated force in the crimp grip and in the campus double dyno. In teenagers, it can fracture from fatigue: 36 of the 37 injuries in the Schöffl series come from repeated loading, and onset is most often insidious. The published series agree on age and on location.

Between 13 and 15, the growth plate of the finger is fragile

Stress fractures of the growth plate are concentrated in three years of growth.

An age axis from 9 to 19. The 13 to 15 zone is marked. A line at 18. Below, the FFME categories U11 to U19. A horizontal age axis from 9 to 19. A thick zone covers 13 to 15, labelled with growth-plate fractures of the finger. A vertical line at 18 marks the campus rule. Under the axis, the FFME categories: U11 from 9 to 10, U13 from 11 to 12, U15 from 13 to 14, U17 from 15 to 16, U19 from 17 to 18.

StudyWhat it shows
Schöffl et al., Am J Sports Med 202227 patients and 37 growth-plate injuries of the finger, age 14.7 ± 1.5; 66.7% competitors; 28 injuries of Salter-Harris type III; 36 of 37 from repeated loading; healing achieved in every case
Jaini et al., PM&R 2026 (scoping review)149 growth-plate stress injuries in 98 climbers, mean age 14 (10 to 18); 98% at the middle finger joint; 74% fractures
German review, Unfallchirurgie 2024more than 200 documented cases, “mostly between 13 and 15”, during the growth spurt
Bärtschi et al., Hand Surg Rehabil 201928 climbers treated, mean age 13.7 ± 1.9; the middle finger (58%) and ring finger (30%) most often affected; 54% fractures, 46% symptomatic sprains
Meyers et al., 2020 (267 young climbers aged 9 to 18)a history of growth-plate fracture is associated with regular training on the standard speed wall (adjusted OR 3.95; 95% CI 1.14 to 13.7): a cross-sectional, self-reported study, which does not prove a cause. Only 6% knew at what age the campus double dyno is safe
McMullen et al., 2021 (73 coaches)46 coaches (63%) have some or all of their climbers do full body-weight campusing; no consensus on who is entitled to it

All these data come from clinics, case series or questionnaires. No study has tested a campus ban, a crimp limit or a loading rule against the occurrence of the injury.

The rule, and who states it

The rule on young climbers' fingers rests on several sources of different weight. Mixing them up makes the BMC say what it has not written.

Rule before 18Who states it
No campusing with feet off or dynamicallyBMC, with the approval of the UIAA Medical Commission: “We advise that climbers aged under 18 do not campus feet-off or dynamically.”
Campusing is not recommendedMorrison and Schöffl, BMC article (2021): “campus board use is not recommended for any climbers aged under 18”
No added weight while climbingthe same article: “Young climbers must not wear any weights while climbing under the age of 18”
Avoid constant crimpingthe same article lists it among the methods that cause damage; Schöffl et al. 2025 conclude on reducing the crimp grip
No maximal hangs (hangboard, max-hang)Paak precaution: neither of the two BMC pages names the hangboard or maximal hangs

The BMC page for over-18s says, for its part, not to campus feet-off or dynamically unless you are an experienced climber who knows what you are doing, to warm up the fingers first and to place it at the start of the session. The page gives no year.

At the first pain on the back of the middle joint of a finger in a young climber aged 10 to 18, Paak's instruction is imaging without delay, not training through the pain. An untreated injury can damage the plate and leave an incongruence of the joint surface, with lasting damage to the finger (Bärtschi 2019).

Injuries by age and sex

  • In adults, the finger first: in one clinic series (836 patients, 911 injuries, 2009 to 2012), the fingers account for 52% of injuries, pulleys are the most frequent finger injury, and A4 pulleys are now more numerous than A2 (Schöffl et al. 2015). In a survey of 667 active climbers on their chronic injuries: fingers 41.3%, shoulders 19.4%, elbows 17.7% (Grønhaug 2018).
  • Shoulders in women, fingers in men: in a survey of 1,513 responses (877 men, 427 women), the shoulders are the first location in women and the fingers in men, with differences at six locations (Grønhaug 2024).
  • Rates in young climbers: 4.44 injuries per 1,000 hours of climbing (95% CI 3.74 to 5.23) in 116 climbers aged 11 to 19, in Alberta (Woollings 2015); 2.7 per 1,000 hours in young American competitors (Barrile 2022). The definitions differ: these two figures cannot be put in one total.
  • Falls: 9% of the FFME climbers surveyed had a fall-related injury in 12 months; no effect of sex; beginners (0 to 3 years of practice) had 1.7 times more than those with 5 to 8 years and 3.6 times more than those with 14 to 23 years (Luiggi 2023). The mechanisms cited: natural falls, unexpected falls and static belaying. It is a matter of belaying competence and supervision, not of a set of exercises.
  • Shoulder, elbow: the surveys above give their share of injuries; the detailed epidemiology (subacromial impingement, labrum tear, epicondylopathy) was not found, and no figure is put forward.

Prevention: what is not proven

The search of 28 October 2026 (PubMed, Europe PMC, ClinicalTrials.gov) found no proven injury-prevention exercise programme in climbers. It has to be said as it is. A 2015 systematic review judges the results on prevention measures inconclusive (Woollings), and the 2023 review on adult overuse injuries calls for new research on prevention programmes; it finds no link between warm-up, cool-down, stretching, taping or hydration and injury risk (Quarmby).

  • The only randomised trial with injury as the outcome: Kozin et al. 2021, 84 physical education students, all men aged 18 and 19, over one year. A 15-minute programme at every session (ring push-ups, feet-on-ground pull-ups, three-point climbing, an eccentric pronation exercise with a 4 kg dumbbell): 3 shoulder injuries per 6,000 exposures, against 21 per 6,600 in the control group. But: injuries were recorded by the athletes and coaches themselves, without blinding; the intervention group also attended a seminar on the causes of injuries; 24 injuries in total; no replication elsewhere. No women, no minors. It is not strong enough to suggest a programme.
  • Under-18s: no trial of any kind.
  • Girls and women: no trial with a female participant, no programme designed for them.
  • The hangboard, antagonist exercises: no trial with injury as the outcome. A core and antagonist exercise in the library is general conditioning; its effect on injuries has not been tested.

So never say that an exercise “prevents pulley injuries” or that the campus board has been “shown to be dangerous” by a trial: the under-18 rule is the advice of a medical commission, based on case series.

What remains: general conditioning

The studies on strength endurance and on antagonist work were not found: no figure or prescription is put forward. The library offers two conditioning drills with no load on the fingers, one on continuity, the other on core; they are in the hub's drill list, presented as common practices, never as proven programmes. Contact strength (campus, hangs, limit bouldering) is reserved for adults aged 18 and over, in another drill of the hub.

Frequently asked questions

Is there a warm-up that prevents climbing injuries?
No, not proven. No warm-up programme has been tested in climbers with injury as the measured outcome, and a systematic review found no association between warm-up, stretching or taping and the risk of overuse injury in adults. A progressive warm-up remains good coaching practice, with no proof of prevention.
Can a 15-year-old do hangs on a hangboard?
No text we read allows it or forbids it by name: the two BMC pages speak of the campus board. Paak's precaution is not to do maximal hangs before 18, and the Morrison and Schöffl article forbids added weight to under-18s.
What should you do about finger pain in a young climber?
Do not train through the pain: pain on the back of the middle finger joint in a young climber aged 10 to 18 calls for imaging without delay.
