Why Some Swimmers Improve Faster Than Others: A Parent's Guide to Swimming Development
One of the most common questions parents ask in competitive swimming is:
"Why does that swimmer seem to improve so much faster than mine?"
Perhaps another swimmer is achieving PB after PB, qualifying for championships or moving through squads more quickly. Meanwhile, your swimmer may appear to be progressing more slowly despite working just as hard.
It's a completely natural question.
The reality, however, is that swimming development is rarely straightforward. Every swimmer follows a unique journey influenced by a wide range of physical, technical, mental and personal factors.
This guide explains why some swimmers improve faster than others and why comparing swimmers is often less useful than many parents realise.
The First Thing to Remember: Every Swimmer Is Different
Swimming is not a sport where every child develops at the same rate.
Two swimmers may:
- Be the same age
- Train in the same squad
- Attend the same sessions
- Have the same coach
Yet experience completely different rates of improvement.
This is entirely normal.
Just because one swimmer improves quickly today doesn't mean they will always progress faster in the future.
Early Developers vs Late Developers
One of the biggest influences on performance is physical development.
Children grow and mature at different rates.
Some swimmers develop earlier and may benefit from:
- Increased strength
- Greater power
- Improved coordination
- Larger body size
This can create significant advantages at younger ages.
However, many swimmers who develop later eventually catch up and sometimes surpass earlier developers.
This is why coaches often focus on long-term development rather than short-term results.
Growth Spurts Can Affect Performance
Parents are often surprised to learn that growth can temporarily affect swimming performance.
As swimmers grow, they may experience changes in:
- Height
- Limb length
- Coordination
- Strength
- Balance
During these periods, swimmers sometimes appear awkward in the water and may even stop achieving PBs for a while.
This is completely normal.
The swimmer is essentially learning how to control a new body shape.
Many swimmers emerge from these periods stronger and faster than before.
Training Age Matters
Swimming parents often focus on a swimmer's actual age.
Coaches often think about training age.
Training age refers to how long someone has been consistently training.
For example:
Swimmer A
13 years old
Swimming competitively for 6 years.
Swimmer B
13 years old
Swimming competitively for 2 years.
Although both swimmers are the same age, their development pathway may look very different.
Swimmer A has had thousands more opportunities to develop:
- Technique
- Race skills
- Confidence
- Competition experience
Training age can have a huge impact on progression.
Technique Makes a Huge Difference
As we've discussed in other Parent Hub articles, swimming is one of the most technical sports in the world.
Small technical differences can create significant performance differences.
For example:
- Better streamlining
- Stronger turns
- Faster breakouts
- More efficient breathing
- Better body position
These improvements often appear as faster race times.
What looks like natural talent is often the result of better technical foundations.
Consistency Often Beats Talent
Swimming rewards consistency.
A swimmer who attends training regularly is likely to accumulate:
- More practice
- More coaching feedback
- Better fitness
- Better habits
Many coaches will tell you:
Consistency often beats talent when talent isn't consistent.
Swimmers who repeatedly attend training and stay engaged often make substantial progress over time.
Confidence Plays a Bigger Role Than People Realise
Swimming is as much mental as physical.
Two swimmers with similar ability may perform very differently depending on confidence levels.
Confident swimmers often:
- Race more aggressively
- Commit to race plans
- Recover better from setbacks
- Enjoy competition more
Meanwhile, a swimmer who lacks confidence may struggle to show their true ability during races.
Confidence is a skill that develops over time.
Some Swimmers Learn Skills More Quickly
Just as children learn differently at school, swimmers learn differently in the pool.
Some swimmers naturally pick up:
- Technique adjustments
- Race strategies
- Skills and drills
- Coaching feedback
more quickly than others.
This doesn't mean they will always be the fastest swimmers.
It simply means their learning journey may initially look different.
Competition Experience Matters
The more swimmers compete, the more experience they gain.
Experienced swimmers often become better at:
- Handling nerves
- Understanding race tactics
- Managing competition days
- Executing race plans
This experience can contribute significantly to improvement.
A swimmer racing frequently may appear to progress faster than a swimmer who has less competition exposure.
Why Comparing Swimmers Can Be Misleading
One of the biggest traps in swimming is comparison.
Parents naturally notice:
- Rankings
- Medals
- Championship qualification
- Squad moves
What they don't always see are:
- Growth differences
- Training history
- Confidence levels
- Technical development
- Personal challenges
Comparing swimmers is often like comparing apples and oranges.
The circumstances are rarely identical.
Why Coaches Focus on Individual Progress
Great coaches typically ask:
Is this swimmer improving?
rather than:
Is this swimmer better than someone else?
Progress can be measured through:
✅ Technique improvements
✅ Better race execution
✅ Increased confidence
✅ Improved attendance
✅ Positive attitude
✅ Learning new skills
PBs and rankings matter, but they are only part of the bigger picture.
The Importance of Patience
Swimming is a long-term sport.
Some swimmers progress rapidly during their early years.
Others improve steadily over a much longer period.
Neither path is necessarily better.
The swimmers who ultimately succeed are often those who:
- Stay patient
- Continue learning
- Attend training consistently
- Trust the coaching process
- Remain positive during setbacks
Trust the Process
By now, you've probably noticed a recurring theme throughout the SportySwim Parent Hub.
Coaches frequently say:
"Trust the process."
There is a reason for that.
Many of the factors that influence improvement take time:
- Technique
- Confidence
- Fitness
- Strength
- Race skills
- Maturity
The swimmers who continue focusing on these fundamentals often achieve the best long-term results.
What Parents Should Focus On
Rather than asking:
"Why is that swimmer improving faster?"
Try asking:
- Is my swimmer learning?
- Is my swimmer enjoying the sport?
- Is my swimmer attending regularly?
- Is confidence improving?
- Is technique improving?
- Is my swimmer developing positive habits?
These are often much better indicators of future success.
Signs Your Swimmer Is Progressing
Progress isn't always visible on a results sheet.
Look for:
✅ Better starts
✅ Faster turns
✅ Improved streamlining
✅ Greater confidence
✅ Better race execution
✅ More independence
✅ Stronger work ethic
✅ Positive attitude
These improvements often appear before the next significant PB.
Frequently Asked Questions
Is it normal for some swimmers to improve faster than others?
Yes. Every swimmer develops at their own rate based on a combination of physical, technical and mental factors.
Does early success predict future success?
Not necessarily. Many successful swimmers develop later than their peers.
Why has my swimmer stopped improving while others continue?
Growth, technique changes, training load and confidence can all influence short-term progress.
Should parents compare swimmers?
Generally, no. Every swimmer follows a unique pathway.
What should parents focus on?
Effort, learning, enjoyment, consistency and long-term development.
Final Thoughts
Swimming development rarely follows a straight line. Some swimmers improve quickly, some develop later and many experience periods where progress appears to slow down.
The key thing for parents to remember is that every swimmer's journey is different. Growth, technique, confidence, training age and consistency all play important roles in shaping development.
The swimmers who thrive in the long term are rarely those who spend their time comparing themselves to others. Instead, they focus on learning, improving and trusting the process.
Because in swimming, success isn't about being ahead of everyone else today.
It's about continuing to move forward on your own journey.
