The Junior Athlete's Training Load
A 15-year-old representative basketball player trains four evenings per week (90 minutes each) and plays two games on weekends, plus school physical education. Over six weeks, the coach records a weekly session load (RPE × minutes). Weeks 1–3 average 1,850 units; week 4 jumps to 3,100 units during a tournament; weeks 5–6 average 2,400 units. The athlete reports sleep of 6.5 hours on school nights, one episode of sharp knee pain during landing in week 4, and has missed two school days with fatigue. The athlete wants to add a strength session and a second team's training.
1. Analyse the training load data and identify the injury and wellbeing risks, explaining the physiological basis.

Analysis:
- Baseline load is 1,850 units. Week 4 rises to 3,100, a 68% increase, well above the commonly used guideline of limiting week-to-week increases to about 10%. Weeks 5–6 fall to 2,400, a 23% drop from the spike, showing an erratic load pattern.
- The acute:chronic workload ratio around week 4 is high (approximately 3,100 divided by the preceding average of about 1,850, i.e. about 1.7), a pattern associated with increased injury risk.
Physiological basis:
- A sudden load spike exceeds the tissue's adapted capacity. Bone, tendon, and cartilage adapt more slowly than muscle and cardiovascular fitness, so rapid increases stress the knee, patellar tendon, and growth plates in an adolescent.
- The sharp knee pain on landing suggests patellofemoral or patellar tendon loading, and in a growing athlete, growth-plate-related pain must be considered. Pain during landing is a warning sign, not normal soreness.
- Sleep of 6.5 hours is below the 8–10 hours recommended for adolescents and impairs recovery, growth hormone release, and mood. Combined with missed school days, this indicates non-functional overreaching rather than normal training fatigue.
Risk: Continued loading risks overuse injury, illness, and burnout. Adding a strength session and a second team now would compound the spike.
2. Recommend a revised plan for the next six weeks and justify each element.

Revised plan:
- Reduce and stabilise load: Bring weekly load back to about 2,000–2,200 units and increase by no more than 10% per week. Avoid tournament spikes by rotating players and capping minutes.
- Delay the extra commitments: Do not add the second team's training this season. Add one short strength session (30–40 minutes, twice weekly, bodyweight and landing mechanics) only after two stable weeks, and count it in the load total.
- Address the knee: Refer for assessment before returning to full landing and cutting drills. Use a graded return with low-impact conditioning, and include eccentric quadriceps and hamstring work and landing technique coaching.
- Protect sleep: Set a target of 8–9 hours on school nights, with a consistent bedtime and reduced screen use before bed. Monitor sleep and fatigue weekly.
- Monitor and communicate: Use a simple daily wellness check (sleep, soreness, mood, fatigue) and a session RPE log. Share data with parents, coach, and school so load is coordinated across settings.
- Prioritise school: Missed school days are a red flag; if fatigue persists after two weeks of reduced load, seek medical review.
Justification: Progressive overload within tissue tolerance builds capacity, while stable sleep and coordinated communication address the recovery and total-load drivers of the problem.
