Hydration for Young Athletes

Health & Nutrition for Young Athletes — Part 3

When children train, run, sweat and play, their bodies lose water.

If they do not replace enough of it, they may feel tired, slow, unfocused or simply “off” during training.

That is why hydration is not just about drinking water when a child feels thirsty.

For young athletes, it is about building a simple habit:

Drink before training → Sip during training → Rehydrate after training

Why Hydration Matters

Water helps the body:

• Regulate temperature
• Support concentration
• Transport nutrients
• Maintain energy during activity
• Recover after training

Even small changes in hydration can affect how a child feels during sport.

Sometimes poor training quality is not only about fitness or effort.

It may also be because the child started the session already under-hydrated.

How Much Water Do Kids Need?

There is no single amount that is perfect for every child.

Water needs can change depending on:

• Age
• Body size
• Weather
• Training duration
• Training intensity
• How much the child sweats

The better approach is to encourage regular drinking throughout the day instead of trying to “catch up” just before training.

Parents can use the:

Use it as a general starting point. Children may need more fluids on hot, humid or harder training days.

Before Training

Children should not wait until practice starts to think about water.

Encourage them to drink regularly during the day and have some water before they step onto the court or field.

A simple question before leaving home can help:

“Do you have your water bottle?”

That small habit matters.

During Training

During training, children should have easy access to water and take regular sips.

They do not need to drink a huge amount at once.

Small, regular amounts are usually easier to tolerate.

For normal coaching sessions, water is often enough.

Coaches and parents should also be more attentive during hot or humid weather, when fluid losses can be higher.

After Training

After training, encourage children to drink again.

If the child has trained hard and sweated a lot, fluids after the session become especially important.

A simple post-training routine can be:

Water + Recovery Food + Rest

For example:

• Water + banana + curd
• Water + milk + fruit
• Water + normal dinner
• Water + sandwich + fruit

Hydration works best when it is part of the full recovery routine.

Signs a Child May Need More Fluids

Parents and coaches can watch for signs such as:

• Increased thirst
• Dry mouth
• Tiredness
• Headache
• Reduced concentration
• Feeling unusually slow
• Darker urine than usual
• Lower energy during training

These signs do not always mean dehydration, but they are useful reminders to check hydration habits.

A very simple everyday cue is urine colour.

Pale yellow usually suggests better hydration. Very dark urine can be a sign that more fluid may be needed.

Water or Sports Drink?

For most normal training sessions, children do not automatically need a sports drink.

Water should usually be the first choice.

Sports or electrolyte drinks may be more useful during situations such as:

• Long-duration training
• Very intense sessions
• Hot and humid conditions
• Heavy sweating
• Multiple matches in one day

They should not become an everyday replacement for water.

Many sports drinks also contain sugar, so they are better used for a reason rather than simply because a child is playing sport.

When Can Electrolytes Help?

Sweat contains not only water but also electrolytes, including sodium.

On longer or hotter training days, especially when a child sweats heavily, replacing electrolytes may sometimes be useful.

This can be more relevant during:

• Summer training
• Long tournament days
• Back-to-back matches
• Multiple training sessions
• Very high sweat loss

For normal daily sessions, regular meals plus water may already provide what many children need.

Hot-Weather Training

Hot weather changes hydration needs.

Children may sweat more and lose fluids faster.

On hot days:

• Encourage drinking before training
• Make sure the bottle is full
• Allow regular water breaks
• Watch for unusual tiredness or dizziness
• Rehydrate after training
• Avoid waiting until the child becomes extremely thirsty

The goal is not to force large amounts of water.

The goal is to make hydration regular and easy.

Tournament-Day Hydration

Tournament days are different from regular training.

A child may play multiple matches, wait between games and stay at the venue for several hours.

A simple routine can help:

Before the First Match

Drink water regularly and avoid starting the day dehydrated.

Between Matches

Take small sips regularly.

Do not wait until the next match starts.

After Matches

Rehydrate and combine fluids with a suitable snack or meal.

Tournament hydration is easier when parents carry:

• Water bottle
• Extra water
• Fruit
• Simple snacks
• Electrolyte option if the day is long, hot or very demanding

A Simple Rule Kids Can Remember

Hydration does not need to be complicated.

Teach children:

Before Training

Start Hydrated

During Training

Sip Regularly

After Training

Replace What You Lost

That is a habit they can carry into any sport.

The Best Hydration Habit Is Consistency

Parents do not need to measure every sip.

The bigger goal is to make water a normal part of the child’s day.

Keep a bottle nearby.

Send one to school.

Bring one to training.

Refill it when needed.

Small habits repeated every day are more useful than suddenly drinking a lot only when training begins.

At CSA, we see hydration as part of the complete athlete-development cycle:

Fuel → Hydrate → Train → Recover → Sleep → Grow

Every part supports the next.
