Biology & Nervous System

Preliminary note: Please, no jumping to conclusions
Statements like 'Teenagers are like that because of hormones' are not scientifically sound. Adolescent behaviour arises from the interplay of biological, psychological, social, and environmental factors.
Biological knowledge helps understand tendencies. It doesn't explain a single situation or excuse behaviour – it just makes it more comprehensible.
Puberty
Physical development happens at different rates. Comparing height, strength, or maturity between teammates says nothing about their self-worth or their sporting future.
If you notice unusual movement patterns or physical complaints, speak with the coaching team and, if necessary, a doctor to decide on sensible adjustments. Do not draw long-term conclusions about development from a single phase of training.
Stress Physiology
A racing heart and tension are normal before a match. This page can't tell whether a physical symptom is down to nerves or something else.
Keep an eye on their mood and everyday life. Lasting symptoms or noticeable changes call for professional advice, not a judgment on their mental toughness.
- There's no set timetable for when a child is ready to talk again.
- A calm breathing exercise can be tried voluntarily. Stop if dizziness or discomfort occurs; it is no substitute for medical advice.
- Taking one small action of your own can provide direction without making every pressure disappear.
Nervous system and emotional regulation
How an emotion is felt and expressed varies from person to person and situation to situation. Ask about pressure and needs rather than reducing a single reaction to biology.
One snappy reaction on a tough evening doesn't define their personality. Check in about the situation later and talk about how you speak to each other.
Hormones – a nuanced view
Don't put conflicts down to "raging hormones". Ask how your child is experiencing things and respect their privacy when it comes to bodily changes.
If you have concerns about eating, body image or changes to the menstrual cycle, seek medical advice. Do not set dietary rules, weight targets or introduce supplements off your own bat; physical symptoms belong in qualified hands.
Experience and brain development
When symptoms keep returning, your child's wellbeing comes first. A quick exercise is no substitute for a medical assessment.
The brain continues developing into early adulthood, shaped directly by experience. Whether a short exercise helps is something your child works out through experience – not because this website promises it will.
Observing without using the body as the explanation
After a growth spurt, movement can suddenly feel unfamiliar. Discuss specific observations with the coaching team, without turning height or development into predictions about the future. If pain, unusual fatigue, or other symptoms appear, consult a doctor.
Physical changes are personal. No weight comparisons, calorie targets, or public discussions about your child's body. Period pain, eating concerns, or changes to the menstrual cycle should also be discussed matter-of-factly with a healthcare professional – without putting sporting goals ahead of health.

- Biology explains tendencies, not individual behaviour.
- Activation is functional – recovery makes it healthy.
- Seek professional advice if there are physical symptoms or unusual changes.
These everyday reflections do not constitute a diagnosis or prove an individual cause. Specific physical or psychological symptoms should always be evaluated by a professional.

These classifications are possibilities, not diagnoses. You know your child better than any text. If you are unsure, a professional assessment is always better than waiting.
