“Is my conditioning good for my age?” doesn’t have one answer, because the honest answer depends on the sport. A 14-year-old distance runner, a 14-year-old swimmer, and a 14-year-old soccer player are all being measured against completely different systems, because each sport has built its own way of tracking whether an athlete’s engine matches their age and level.
This guide walks through how conditioning is actually benchmarked in four widely tested sports, using the real testing systems coaches and governing bodies use, with sample age-by-age numbers pulled from those standards, so you can see what “good” looks like in the sport that actually matters to you rather than a generic age chart.
Quick Answer
There’s no single conditioning standard that applies across sports, and each one ties its benchmark to a specific age. Distance running and general school fitness use tests like the FitnessGram mile run/PACER (youth), which sets a maximum “Healthy Fitness Zone” time for each age and sex (for example, roughly an 11:30 mile or faster at age 10, dropping toward the 9-minute range by age 15 for boys, with a slightly more gradual drop for girls), and USATF/World Masters age-grading tables for adults. Competitive swimming uses USA Swimming’s National Age Group Motivational Times, tiered by age bracket. Soccer conditioning is commonly tested with the Yo-Yo Intermittent Recovery Test, where total distance covered roughly doubles from the early teens (U13 squads often cover several hundred meters) to the late teens (elite U19 players can cover well over 2,000 meters). Basketball conditioning is often gauged through vertical jump and agility testing, where a “good” jump climbs from roughly the low-to-mid-teens in inches around age 12 to the high-teens/low-20s by age 16 and beyond. Each system accounts for age and sex differently, so “good” only means something within that sport’s own scale.
Running and General Aerobic Fitness
For school-age kids, the most widely used benchmark in the U.S. is FitnessGram, developed with The Cooper Institute and used in the Presidential Youth Fitness Program. It scores the one-mile run or the PACER shuttle-run test against a ‘Healthy Fitness Zone’ (HFZ) for each age and sex, a criterion-referenced range meant to reflect a level of aerobic fitness associated with health, not a competitive ranking. As a sense of scale, the HFZ maximum mile time for boys runs from roughly 11:30 at age 10 down to around 9:00-9:20 by age 15, while for girls it runs from about 11:30 at age 10 down to around 10:00-10:20 by age 15 (exact cutoffs shift slightly with each edition of the standards, so treat these as ballpark figures rather than the current published table). A student landing at or under their age-and-sex cutoff on the mile run, or the equivalent PACER lap count, is considered conditioned appropriately for their age; times well above it flag a need for more aerobic work.
For adult and masters runners, the comparable system is USATF/World Masters Athletics age-grading. Instead of a fixed time, your finish time at a given distance is converted into an age-graded percentage that estimates how it compares to the best possible performance for your age and sex. Roughly, scores above 70% are considered regional class, above 80% national class, and above 90% world class, which gives older runners a way to track genuine conditioning progress even as raw times naturally slow with age.
Swimming
Competitive swimming has one of the most structured age-based systems of any sport: USA Swimming’s National Age Group Motivational Times. These are published in tiers, from B and BB up through A, AA, AAA, and AAAA, for the standard age brackets (10 & under, 11-12, 13-14, 15-16, 17-18), separately by sex, stroke, and distance. A swimmer hitting the ‘A’ standard for their age group is swimming solidly for their age; AAAA represents a very small slice of swimmers nationally in that age group. Times are refreshed on a multi-year cycle so the bar keeps pace with how the sport as a whole is improving, which is also why this guide doesn’t print specific cutoff times here, since they age out quickly (check USA Swimming’s current published tables for the exact figure for a given age, sex, stroke, and distance).
Because the standards reset at each new age bracket, a swimmer’s conditioning progress is really measured by whether they hold or climb standard levels as they age up, not just by whether their raw times get faster (times should improve even with no fitness gain simply from growth and technique).
Soccer
Youth and academy soccer programs commonly assess conditioning with the Yo-Yo Intermittent Recovery Test (Level 1), a shuttle-run test with brief active-recovery jogs built in to mimic the stop-start demands of a match, unlike a steady-pace beep test. In published youth-development research, total distance covered climbs sharply with age: club-level U13 players have averaged distances in the roughly 800-1,200 meter range, U16 players have averaged distances in the roughly 1,500-1,600 meter range, and elite academy players in the U15-U19 range have posted average distances from around 2,000 meters up past 2,500 meters by U19. Those numbers vary by study, league, and playing level, but the pattern is consistent: covering meaningfully more ground on this test in the late teens than in the early teens is expected, not exceptional, as aerobic capacity and repeated-sprint ability develop.
Because soccer conditioning blends aerobic endurance with repeated high-intensity bursts, a player who does well on a straight distance run but fades on Yo-Yo-style intervals usually has a conditioning gap specific to match demands, not a lack of general fitness.
Basketball
Basketball conditioning is typically assessed through a mix of vertical jump testing and on-court agility drills rather than a single official age-based chart. Vertical jump in particular climbs sharply through adolescence: a roughly 12-15 inch jump is commonly cited as solid for a 12-year-old, climbing to roughly 17-21 inches as “good” and above 22 inches as strong by around age 14, and into the high-teens to low-20s (often cited as roughly 18-22 inches) by age 16. From there it keeps climbing into the early-to-mid 20s for athletes who train it, with high-school varsity players commonly landing in the low-to-mid 20-inch range and college-level players often higher, before gradually declining in adulthood without targeted work. Camps, combines, and college programs use vertical jump alongside agility and conditioning drills (shuttle runs, lane sprints) as a practical snapshot of an athlete’s power and repeat-effort capacity relative to their level.
Because these tests aren’t standardized the way swimming’s or school fitness testing is, the most useful comparison for a basketball player is usually against their own team or league level, tracked over time, rather than a fixed external number.
Tips and Common Mistakes
The biggest mistake is borrowing a benchmark from the wrong sport, expecting a soccer player’s conditioning to look like a swimmer’s, or judging a 12-year-old against a standard built for 16-year-olds. Match the test, and the age-specific number, to the sport it was actually built for.
The second common mistake, especially with kids under 12, is testing too early and too formally. Most youth development frameworks favor broad movement skill and enjoyment before age 10-12, with structured, sport-specific conditioning testing becoming more meaningful in the mid-teens as training itself becomes more structured.
Across every sport, the standards above are most useful as a way to track an athlete’s own trajectory over time, not as a one-time pass/fail grade. A swimmer holding their AA standard as they age up, a runner maintaining their age-graded percentage year over year, or a soccer player adding meters to their Yo-Yo distance each season tells you more about real conditioning progress than any single test result.

Conditioning standards by sport and age FAQs
Which sport has the most standardized conditioning benchmarks by age?
Competitive swimming is probably the most formally standardized, through USA Swimming’s National Age Group Motivational Times, which set specific time standards by age bracket, sex, stroke, and distance. School-age general fitness (FitnessGram) is similarly standardized for aerobic capacity, strength, and flexibility, with published maximum times for the mile run at each age and sex.
Can I compare conditioning test results across different sports?
Not directly. A strong FitnessGram mile time doesn’t translate into a strong Yo-Yo Intermittent Recovery score, because the tests measure different things (steady-state aerobic capacity versus repeated high-intensity effort with recovery). Use the test built for the sport you’re evaluating, and compare against the age-specific benchmark for that test.
At what age should sport-specific conditioning testing start?
Most youth development frameworks suggest holding off on formal, sport-specific conditioning testing until the early-to-mid teens, once an athlete has built general movement skill and basic strength. Before that, broad activity and skill development matter more than test scores.
