If a test is too imprecise, it can merely simulate training progress
New data on sprint and step tests show which swimming metrics are reliable enough to detect small changes for real.

Five resisted 25s: Sprint profiling now measurable with a portable device
A study published only in September 2026 shows that load–velocity profiles in freestyle can be measured reliably with a simple portable resistance device.
Tethered swimming: Which force values are truly reliable
Ten- and 30-second tethered tests were repeated on three days. Mean force, peak force and impulse proved to be particularly stable metrics.
Force plate for swimmers: Can it help with return-to-swim?
A recent study tested shoulder, push-up and jump assessments on force plates in 32 university swimmers—with very different results.
Fewer test metres, similar information? A new short step test in the pool
A pilot project examines whether a compact test using 50, 100, 150 and 200 metres can replace parts of a classic 7×200 m step test.
Predicting 1500 m freestyle with data
Data models are becoming increasingly powerful in swimming as well.
Diagnostics for young swimmers
Technical factors can also be measured objectively in youth swimming—although diagnostics should remain age-appropriate.
Lactate and muscle-fibre type in swimming
Can performance testing help distinguish sprint and endurance talent more effectively?
