Parent guide: intensive training in young athletes
Sport supports health, skills and valuable experiences. When practices, matches and other activities accumulate, the question is whether the load allows the young athlete to recover, grow and keep enjoying sport. This guide helps structure that conversation with the coach and clinician.
The focus is the young athlete’s physical health. Planning figures help review training; none guarantees freedom from injury. Individual assessment considers age, maturation, intensity, history and symptoms.
Before deciding: count the actual load
Sport can offer health, skills and enjoyment. This guide focuses on protecting a young athlete’s physical health and helping families recognise when load exceeds recovery. More training is not always better training.
Count every organised activity: sports school, club, representative team, matches and demanding classes. Record duration, but also intensity, repetitions and travel or tournaments. The same number of hours can involve different demands.
Listen to your child: how they feel during practice, afterwards and the following morning. A schedule compatible with sleep, food, school and rest matters as much as preparation for competition.

Traffic light for load, symptoms and recovery
Use each row as a signal for discussion and decisions. Green means continue monitoring and recovery; amber means review and adjust; red means prioritise assessment or pause the activity provoking symptoms. A limp, focal bone pain, pain at rest or loss of function takes priority over a low number of training hours.
Weekly organised sport hours
Green · routine monitoring
Compare hours with age and check recovery: hours ≤ age is a planning reference.
Amber · review
More hours than age, several clubs/teams or rising commitments: review the total, even without pain.
Red · assess or pause
Volumes of 16–20 hours/week or more merit particular review, especially in younger children; they are not a diagnosis or universal limit.
Weekly rest days
Green · routine monitoring
Plan 1–2 days without competition or sport-specific training.
Amber · review
Only 0–1 rest day, or rest lost when combining teams: review the schedule.
Red · assess or pause
No scheduled rest day, especially over several weeks. Do not wait for an injury.
What to do: Protect genuine rest. Replacing one session with another demanding practice does not provide a break from organised training.
General AAP recommendation; individualise the schedule.
Sources: [1]
Months each year in the same sport
Green · routine monitoring
Up to 8 months: the original guide’s conservative reference for breaks and variety.
Amber · review
9–10 months: confirm 2–3 months each year away from that sport; the number alone does not make a plan unsafe.
Red · assess or pause
11–12 months without a clear off-season: review the annual schedule.
Increase in volume or intensity
Green · routine monitoring
Gradual changes, maintained technique and good recovery. The original ≈10% weekly figure is a reference, not a compulsory target.
Amber · review
Changes around 10–20%, crowded tournaments or simultaneous rises in volume and intensity: monitor the response.
Red · assess or pause
Abrupt load changes, repeated spikes, accumulating pain or fatigue. No percentage guarantees tolerance.
Pain and function
Green · routine monitoring
No limp or altered technique. Record mild, brief discomfort; it is not automatic permission to continue training.
Amber · review
Repeated pain, pain lasting into the next day or limiting a session. The original 0–2/10 and 3–5/10 bands describe symptoms; they do not diagnose injury.
Red · assess or pause
Limp, swelling, focal bone pain, pain at rest/night or loss of function: stop impact activity and arrange assessment.
Energy, growth and recovery
Green · routine monitoring
No concerning changes in appetite, sleep or recovery; growth followed at routine visits. Stable weight does not rule out low energy availability.
Amber · review
Persistent fatigue, reduced appetite, poorer performance or repeated injuries: discuss and review.
Red · assess or pause
Weight loss, faltering growth, dizziness, bone stress injuries or menstrual changes: prioritise medical and nutritional assessment.
What to do: Girls and boys can be affected. Review energy needed for growth and recovery; do not start restrictive diets or diagnose REDs using this table.

Example: age 10 and 5 hours of training a day
An educational example from the original guide; it does not describe a diagnosis or a current clinical case.
With 5 hours of training each day, the total depends on how many days training takes place:
- 5 days × 5 h = 25 h/week
- 6 days × 5 h = 30 h/week
- 7 days × 5 h = 35 h/week
This is a high load that merits individual review for a 10-year-old, particularly if it leaves little time for sleep, meals, school, play and recovery. Comparing the total with one figure is not enough: the amount of intense activity, the breaks and the child’s response matter.
- Check what each five-hour block includes: intense activity, technique, breaks or other tasks.
- Bring together the full training and competition schedule, including other teams.
- Agree on genuine rest and adjustments with the coach and clinician; high-performance programmes also need periodisation and supervision.
- Act on pain, limping or poor recovery without waiting for the season to end.
When to adjust, stop or seek assessment
If pain returns each week, sleep or performance worsens, or fatigue accumulates, review the plan promptly with the coach and the clinician caring for your child. Do not treat these changes as a lack of discipline.
A 20–40% load reduction and a review after 2–3 weeks are examples of individual planning in this guide. The percentage and timing are agreed for each case; they do not justify waiting when warning signs appear.
Pause running, jumping or other impact when there is focal bone pain, limping, swelling or loss of function. Back pain with hyperextension or radiating pain also deserves assessment. Avoid repeating the painful movement to test tolerance.
After trauma, breathing difficulty, confusion, deformity, inability to bear weight or a cold/numb limb needs emergency care. Do not simply wait for a routine appointment.
Physical problems we aim to prevent
Overuse injuries can develop when load is repeated without enough recovery. They may affect tendons, growth plates and bone: examples include Sever’s or Osgood-Schlatter symptoms and bone stress injuries in the tibia or metatarsals. Stress injuries can also affect the lower spine, such as spondylolysis. Not every childhood ache is “growing pain”.
Fatigue can make movement control more difficult. Previous injury, deteriorating technique or equipment that no longer fits should also be considered when planning effort.
Long sessions in hot conditions require planned breaks, access to fluids and adjustments to timing and intensity. Dizziness, weakness, nausea or feeling unwell during exercise in heat means stopping activity and seeking help according to severity.
REDs: insufficient energy for training, growth and recovery
Low energy availability means the energy remaining after exercise is insufficient for the body’s needs. Girls and boys can be affected; this is not limited to aesthetic or weight-category sports.
Watch for changes in weight or growth, persistent fatigue, repeated or bone stress injuries, changes in menstrual cycles or delayed first menstruation. Appetite or appearance alone cannot confirm or exclude the problem.
This guide does not diagnose RED-S. Arrange medical and sports-nutrition assessment when these signals appear, protecting growth, bone health and the relationship with food. The 2023 IOC consensus describes its possible effects on health and performance.

Prevention organised by impact and effort
Start with changes your family can sustain. A simple plan that is followed is more useful than a long list that does not fit the schedule.
High impact / low effort
- Protect weekly rest and record hours, pain, sleep and fatigue.
- Avoid continuing impact activities with persistent pain or a limp.
- Share one calendar across family, coaches and teams to identify overlapping sessions.
High impact / moderate effort
- Plan preparticipation assessment and routine follow-up; seek earlier advice for recurring pain.
- Review sufficient nutrition and individual bone-health needs. Calcium or vitamin D should not become a supplement prescription for everyone.
- Review footwear/equipment and technique, progressions and landings, with coaching or physiotherapy support where appropriate.
Moderate impact / greater effort
- Organise seasons, competitions and lighter weeks. The original lighter week every 3–5 weeks is a planning option, not a universal requirement.
- Consider preventive strength, mobility and movement-control work; the original 2–3 weekly sessions are an example to adapt to total load.
- Vary suitable activities to reduce repetition without filling every rest day with another demanding practice.
Rest, sleep, food and strength
Taking a break from competition and structured practice does not erase all progress. Free play and suitable other activities can be part of an active life when an injury does not restrict them.
For general health, AASM recommends 9–12 hours of sleep each day at ages 6–12 and 8–10 at ages 13–18. Review regularity and quality as well; early training should not consistently replace needed sleep.
Plan meals and opportunities to eat around the sports day. Seek individual assessment when recovery, growth or the relationship with food is concerning rather than imposing restrictive diets.
Strength work can suit age and development when technique and supervision are appropriate. It is not limited to lifting weights: body control and well-taught progression matter too. Do not add prevention sessions without reviewing whether the child is already overloaded.
Weekly record to print and review together
Complete one row each day. Add several teams to a row or use an extra sheet. The aim is to recognise trends and prepare for a consultation, without turning the record into a test for the child.

How to use the record
- Record actual minutes from all organised sessions; divide the total by 60 to obtain hours.
- Describe pain before, during, after and the following day. A 0–10 score helps describe it but does not determine whether training is appropriate.
- Record matches, tournaments and preventive training: they also contribute to the load.
- Bring the sheet to the consultation if symptoms recur or the schedule needs adjustment.
The record helps recognise trends and prepare for a consultation; it is not a self-diagnosis tool. If assessment is needed, seek care without waiting to complete the week.

Applying the guide to common situations
These situations guide discussion; they are not treatment prescriptions.
Fatigue, repeated pain or insufficient sleep accumulate
Review the schedule and reduce or redistribute the load causing problems. The original guide’s 20–40% reduction and review after 2–3 weeks are examples of an individual plan, not an automatic instruction. Arrange an earlier assessment if symptoms worsen or function is lost.
Sources: [1]
Limping, focal bone pain or loss of function appears
Pause impact or painful activity and arrange assessment. Do not use jumping tests to check tolerance or painkillers to finish a session. After trauma, deformity, inability to bear weight, numbness or a cold limb needs prompt care.
Sources: [9]
Weight loss, slowing growth or repeated injuries occur
Prioritise medical and nutrition assessment. Menstrual changes in teenagers are also an important signal. These findings have several possible causes; the healthcare team determines whether low energy availability or another problem is present.
Sources: [5]
Pain at night or at rest, persistent swelling or symptoms limiting everyday life also justify consultation. Urgency depends on the context and accompanying signs.
Agree a plan that can be reviewed
Discuss what your child wants to keep doing, what feels difficult and what they enjoy. Loss of interest, irritability or feeling forced to train deserves listening alongside review of physical demands.
Ask the coach and clinician for specific guidance: permitted activities, load adjustments, signs to stop and a reassessment date or criteria. Return is based on injury and recovery, not simply the next championship.
Keep the record for family discussion and the appointment. It helps reveal patterns; it does not diagnose an injury, grade the child or establish that a green light guarantees safety.
