2. Top-100 Study
The purpose of this study was to investigate the performances of elite level swimmers based on the USA Swimming’s All-Time Top 100 times.
May early high-level performances limit a swimmer’s progression later in his/her career?

3. Methods
Analysis of USA Swimming’s All-Time Top 100 age group times by girls and boys.
Five age groups: 10-under, 11-12, 13-14, 15-16, and
Swimming events: 100, 200, and 500 freestyle; 100 and 200 backstroke; 100 and 200 breaststroke; 100 and 200 butterfly; and the 200 individual medley.

8. Age vs 17-18
There is still a low number of elite swimmers at age for girls and boys.
About half of the elite swimmers in the Top 100 at age were new swimmers who were never ranked in the Top 100 at any age.
This statistics shows that most of the future elite swimmers swim under Top 100 times until age

9. Females vs Males
There is a small difference between elite female and male freestyle swimmers at age and 13-14, where it appears that higher numbers of female freestylers were ranked in the Top 100.
Higher numbers for females may be related to earlier biological maturation in girls.

10. Selection of Main Event by Females
51.6% of elite female swimmers are listed in other events at age 10 and under.
This number decreases with age and reaches 37.9%, 26.6% and 24.9% at age 11-12, and 15-16, respectively.
Most of elite female swimmers select their event at age

11. Selection of Main Event by Males
69.6% of elite male swimmers are listed in other events at age 10 and under.
This number decreases with age and reaches 55.6%, 40.8% and 26.7% at age 11-12, and 15-16, respectively.
The elite male swimmers select their events at age or about 2 years later than elite female swimmers.

12. Conclusion 1
A small number of elite swimmers from the Top 100 at age were ranked in the Top 100 at a younger age. Typically, a little over 10 % were ranked as a 10-under, less than 20% as a year old, a little over 30% as a year old, and about 50% as a year old.

13. Conclusion 2
The analysis shows that most of elite level swimmers were unknown at young ages. About a half of elite swimmers at Top 100 at age are new swimmers, which never were listed at Top 100 at any age. Most of future elite swimmers swim slower than age group champions, especially at ages until years.

14. Conclusion 3
Many participants ranked in the Top 100 as age groupers are not present in the Top 100 as they become an elite swimmer in the age group. It may be related to their early biological maturation and/or a high training volume and intensities at a young age.

15. Conclusion 4
Elite level swimmers change their events during long-term training. Elite female swimmers tend to change their events until the age of Elite male swimmers tend to change their events until the age of

PUBERTY
Age 12-17:
Improved attention and decision making skills
Rapid growth and development (sensitive period). Decrease in strength and power because of rapid growth.
Improved aerobic capacity
Deterioration in postural and balance skills (it is important to continue working on swimming skills at this age)
Greater potential of skeletal-muscular injuries

POSTPUBERTY
Age 16-19:
Appreciation of variety in training and swimming sets
Improvements in racing skills
Increased muscle mass and tolerance to the high-intensity work (anaerobic capacity)
Increased sprinting ability (strength and power)
Improved cardio-vascular system

41. Sensitive Periods of Development
Physical characteristics and physiological systems develop at different rates during maturation.
During the adolescent growth spurt many parameters show accelerated growth size and strength.
These accelerated phases of development are called “sensitive periods” and represent the fastest rate of development.

Measure height at least twice a year. Increase workload volumes accordingly:

64. Optimizing Long-Term Training
Identify early/late maturers:
Early maturers experience early success due to physical growth advantage
Early success does not predict later success
Late maturers often catch up and exceed the performance of early maturers
Keep success in perspective
Develop sets to monitor individual progression

65. Optimizing Long-Term Training
Evaluate distance orientation (sprint, middle distance, distance):
