Here is a fairly typical week for a 15-year-old tournament player. Tennis practice five days a week, Monday to Friday. Strength and conditioning on top of that, Tuesday and Thursday. A mental performance session on video every other Sunday. A tournament most weekends.

Three professionals work with this player every week, each of them competent, and in many cases they have never been in the same room. The strength coach programs heavy lower-body work on Thursday without knowing Friday is a high-volume live-ball session before a three-match tournament day. The mental performance coach is building a between-point routine the tennis coach has never seen and occasionally talks over. The tennis coach is rebuilding the backhand while the player’s tournament schedule says it is a competition month.

The only person holding the whole calendar is usually the parent, and the parent is the person least equipped to integrate it.

What the research calls it

Sport science has a name for this pattern. A 2026 paper on multidisciplinary support teams describes specialists working in silos, which leads to fragmented athlete support and over-specialised advice. A survey of high-performance practitioners found that the teams that collaborate well share a few features: role clarity, a shared mental model of the athlete, learning outside their own discipline, and leadership that makes collaboration a priority.

When this works, the results are concrete. At one professional football academy, technical coaches, sports scientists, and medical staff planned together around players in the growth spurt and reduced injury incidence and burden in the highest-risk group. The interventions were ordinary ones, delivered by staff who were finally working from the same plan.

Most junior tennis players will never have an academy support team. They have an independent tennis coach, a trainer at a gym, and maybe a mental coach found through a friend. The principle still scales down to that.

What a shared plan looks like

1. One development calendar. Training blocks, tournaments, school exams, travel, and recovery weeks on a single shared calendar every professional can see. Most load mistakes are calendar mistakes.
2. Three or four priorities per cycle. Every six to eight weeks, agree on a short list of priorities written in plain language, and map each professional’s work to them. If the priority is holding court position against deep, heavy balls, the tennis coach works on recovery footwork and depth patterns, the strength coach on lateral deceleration and single-leg strength, and the mental coach on a reset routine for the moments the player gets pushed back.
3. A weekly load note. One short message from the tennis coach: hours on court, intensity, what is coming at the weekend. The strength coach adjusts. It takes two minutes to write.
4. The meeting. Twenty minutes, once a month, every professional on one call. Review the priorities, the calendar, and anything the player or family has raised. This is the meeting that almost never happens.
5. Shared language. Agree on the cue words and use them across sessions. A player who hears “early contact” from the tennis coach and “load the back leg” from the strength coach should be able to hear how they connect.
6. One accountable person. Someone owns the whole plan, keeps the calendar honest, and is the single voice the family hears. In most setups it should be the head tennis coach. When nobody owns it, the parent ends up owning it by default.

What it asks of coaches

This asks coaches to share information they have often guarded and to accept that their sessions sit inside a bigger plan. It is a real cultural shift, especially in a sport where coaches are independent and competition for players is constant. The players who benefit are the ones whose coaches decide that the player’s development matters more than who gets the credit for it.

If you coach a player who works with other specialists, send them one message this week with your current priorities and the next eight weeks of the calendar. It is the cheapest performance intervention in junior tennis.
