FOR COMPETITIVE SWIMMERS & COACHES
OptiSwim BASE monitors training load, sleep, and recovery with sports-science-based alerts that catch shoulder overuse before it becomes an injury. Built for swim teams and coaches — no wearables required. From the makers of OptiRun BASE, the condition-monitoring platform proven with running teams in Japan.
THE PROBLEM
Injury prevalence in competitive swimming runs 32-74%, and most of it is the shoulder. On most teams, nothing happens until a swimmer reports pain.
Dozens of swimmers per lane group. Tracking every athlete's sleep, fatigue, and soreness daily is physically impossible — until someone is already out.
Doubles are the norm in swimming. Whether fueling and sleep actually match that workload is impossible to judge by feel alone.

SWIMMER'S SHOULDER
Tape and treatment after the pain starts is too late. The only realistic prevention is catching the warning signs in daily load and condition - and adjusting before it hurts.
That is why daily monitoring of training load and athlete condition matters. The IOC recommends internal training-load monitoring in competitive swimming environments.


CONDITION
Sleep, fatigue and shoulder pain in one tap. Light enough to do every day - and every entry sharpens each swimmer's personal baseline.

ALERT
Deviations from personal baselines and sudden load spikes are combined into one clear flag, so no swimmer slips through - even on a large squad.

TAPERING
Volume coming down, intensity intact, frequency held. OptiSwim BASE checks your taper against the shape research says works - every day until race day.
FEATURES
Designed to work with just a phone. Meters and yards, SCY and LCM — supported from day one.
Sleep, fatigue, and soreness (shoulder, back, knee) logged in 30 seconds. As data accumulates, OptiSwim flags deviations from each swimmer's own baseline.
Load spikes overlaid with pain and fatigue signals generate automatic alerts to the coach — so training can be adjusted before it hurts.
Type or paste your workout in standard set notation. OptiSwim parses stroke, reps, and intervals, and totals weekly volume automatically.
8x100 Fr @1:30 → 800m logged with intensityA 400/200 time trial computes each swimmer's Critical Swim Speed and individual training zones. No heart-rate strap needed in the water.
Best times tracked separately for SCY, SCM, and LCM, with automatic World Aquatics Points conversion — one yardstick for progress across events and ages.
Every swimmer's condition and alerts on one screen, so you know who to talk to on deck. Taper readiness scoring is planned as well.
TAPERING SCIENCE
Swimming is the most-studied sport in tapering research. OptiSwim BASE turns that evidence into a daily tool.
OptiSwim BASE tracks volume, intensity and frequency from your daily set log and shows whether your taper is on course. In a sport decided by hundredths of a second, 2% is everything.
