Nutrition, sleep, yoga, stretching, and recovery.

Fuel

A surprising share of junior "mental" collapses are energy problems. A player who eats breakfast at 7am, plays at 10am, and plays again at 4pm without a plan is not having a confidence crisis in the third set — they're empty.

The tournament-day pattern that works

• Breakfast two to three hours before the first match: carbohydrate-led, familiar, nothing new.
• During the match: something drinkable with carbohydrate and electrolytes. Changeovers are feeding opportunities, not just sitting.
• Immediately after: carbohydrate plus protein within about an hour, especially if there's a second match or a next-day match.
• Between matches: small and digestible. A full meal with ninety minutes before the next call is a mistake players make once.
• Evening: the real refuelling meal. Most juniors under-eat here, then wonder why day three is flat.

Never experiment on tournament day. New foods, new drinks, and new supplements are for training weeks.

Hydration and heat

Cramping is rarely just "not enough water" — it's usually a combination of fluid loss, sodium loss, and accumulated load. Start hydrated rather than catching up mid-match, include sodium in hot conditions, and treat a player's sweat rate as individual. Two players in the same draw can have very different needs.

Sleep

If you could buy one performance intervention for a junior, it would be an extra hour of sleep. It outperforms most extra court hours and nearly every supplement, and it's free.

• Consistent windows matter more than total hours on any single night.
• After a late match, the nervous system is still active. A wind-down routine — low light, no screens, breathing — beats lying in bed replaying points.
• Travel: shift toward the destination's clock a day or two early where possible, and get morning daylight on arrival.
• Growth phases increase sleep need. A fourteen-year-old training fifteen hours a week is not an adult.

Mobility

Ten consistent minutes beats an hour once a week. Priorities for tennis players: hips and thoracic spine for rotation, shoulders for serve integrity, ankles for deceleration.

Yoga is the most under-used tool in junior tennis — cheap, scalable, and it doubles as breathing and attention training. Two sessions a week costs almost nothing relative to the rest of a tennis budget.

Note the difference between warm-up (active, before play, raising temperature and preparing movement) and stretching (longer holds, after play or in separate sessions). Static stretching immediately before a match is not a warm-up.

Mind

Recovery isn't only physical. A player who finishes a match and spends four hours replaying it on a phone hasn't recovered.

• Between-point routine — the three seconds after losing a point is the most trainable moment in tennis.
• Breathing — a simple extended-exhale pattern on changeovers, practised in training so it's available in matches.
• Journaling — three lines after a match: what worked, what didn't, one thing for tomorrow. Closes the loop and stops the rumination.
• Boundaries — the match post-mortem on the drive home is, for most families, counterproductive. Agree a time and keep it there.

Who should own this

For most competitive juniors, a one-off nutrition consult plus a check-in is better value than an ongoing retainer, and the fitness trainer usually owns mobility and load. Recovery support scales up around heavy tournament blocks. The Team Builder maps which of these roles to add next, and this article covers the physical side in detail.

If recovery keeps getting squeezed out of the week, that's a scheduling problem rather than a discipline problem. The Training Schedule Planner is the place to start.
