What mental training can do – and what it can’t

Editorial background text · Status 18.6.2026

"Mental training" sounds like a shortcut. It isn't.

What's happening right now?

  • · Psychological skills work like technical ones: They need repetition in training, not just in competitive situations.
  • · Brief interventions change attention and activation, not talent, technique, or playing time.

Why does that happen?

  • · Self-talk and goal-setting show reliable, but moderate, meta-analytic effects (Hatzigeorgiadis et al., 2011; Kyllo & Landers, 1995).
  • · Imagery complements physical training, it doesn't replace it (Simonsmeier et al., 2021).
  • · For mental illnesses, mental training is not a substitute for treatment (Reardon et al., 2019).

What can you do?

  • · Choose one tool per situation and practise it in training for four weeks.
  • · Measure success by process, not outcome.
  • · If stress is persistent, involve a professional instead of training harder.

Try this

Choose one tool and use it in the same spot in the next three training sessions.

When to get help

  • · If symptoms last longer than two to four weeks or limit daily life.
Safety & Support

For Parents

What we know

  • · Psychological skills are trainable and have a positive overall effect.

What we don't know

  • · How significant the benefit is for an individual child.

What that means in practice

  • · Offer exercises, don't control them. Don't attach performance promises to them.
