Hydration for teen (ages 14-17) doing soccer
Training-day target 3,100 ml/day. Near-constant movement with bursts of sprinting. Fluid loss scales quickly on warm days and the sport's culture of 'tough it out' routinely under-hydrates kids.

Teen athletes (ages 14-17) doing youth soccer face a different hydration problem than either the general age group or the general sport. Near-constant movement with bursts of sprinting. Fluid loss scales quickly on warm days and the sport's culture of 'tough it out' routinely under-hydrates kids. Field sports combine aerobic base + repeated sprints. Sweat rates of 500-900 ml/hour are typical for youth matches, higher in hot weather or on artificial turf. Full competitive load — multi-session training days, double-headers, and tournament weekends are routine. Target 3,100 ml (3.1 L) of total fluids on a training day — approximately 700 ml above the teen (ages 14-17) baseline to cover the session's fluid loss.
Targets for teen athletes (ages 14-17) doing youth soccer
Training-day target for teen athletes (ages 14-17): 3,100 ml
Baseline for the teen (ages 14-17) age band is 2,400 ml from IOM pediatric guidance. youth soccer adds approximately 700 ml on top, covering the ~650 ml lost in a typical 75-minute session.

Pre / during / post — the only framework that matters
Start the session ahead, not catching up. For this age band and sport: a pre-session dose 60-90 minutes before, scheduled sips during, and weight-based replacement after. Non-training days use the age-band baseline only — don't over-drink on rest days.
Urine colour is the cleanest daily signal
Pale straw by the mid-afternoon bathroom visit means the athlete started the session hydrated. Dark yellow or amber before training means a pre-session 500 ml top-up, not 'just start'.
Age maturity: Full competitive load — multi-session training days, double-headers, and tournament weekends are routine.
Match intake to real session length. A preschooler's 'soccer practice' is structurally different from a teen's — don't apply teen protocols to 5-year-olds, and don't apply preschool protocols to competitive tweens.
Practical tips for this age and sport
- Pre-match: 300-500 ml in the hour before kickoff, split across two drinks
- Halftime: 250-400 ml minimum — mandatory, not 'if thirsty'
- On-bench: sip every 10-15 minutes if rotating off the field
- Post-match: 500 ml within 30 minutes + salt from a snack (pretzel, cheese slice)
- Weigh pre/post for a week to calibrate the athlete's actual sweat rate
- Caffeine + pre-workout products: only with adult guidance; plain water + electrolytes handle 95% of needs

Signs of Dehydration
- Dizziness on standing after a hard set — immediate stop, 500 ml, no return without clearance
- Urine darker than light straw before training — pre-session deficit, top up 500 ml before starting
- Performance drop in the last third of the session — classic hydration signal, not 'being tired'
- Headache or nausea during or after training — stop, hydrate, don't push through
Frequently Asked Questions
How much water does a teen kid need on a youth soccer day?
About 3,100 ml (3.1 L) of total fluids across the day. Baseline for this age band is 2,400 ml, and youth soccer adds the rest to cover the 75-minute session's fluid loss.
What's the pre / during / post split for this age and sport?
Pre 500-700 ml in the 90-120 minutes before, during 250 ml every 15-20 minutes, post 1.5× any body-weight drop across the next 2 hours. Electrolyte during sessions >60 minutes of moderate-to-high intensity.
What about sports drinks — does youth soccer need them at this age?
For sessions or matches over 60 minutes at moderate-to-high intensity, yes. Otherwise water + a balanced post-session meal is better than a sports drink with added sugar.
