Grip Strength Dynamometer & Rate of Force Development (RFD) Tutor
Interpret Jamar / Camry / EH101 grip readings against age/sex population norms (Massy-Westropp 2011: z-score, percentile, % of norm), sarcopenia weakness cutoffs (EWGSOP2, AWGS, Fried), the 10% asymmetry rule; compute rate of force development from force-time curves (0–50…0–250 ms windows, peak RFD, impulse, time-to-peak per Maffiuletti 2016); and repeated-trial fatigue index.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/grip-strength-dynamometer-and-rate-of-force-development-tutor' \
-H 'Content-Type: application/json' \
-d '{"mode":"norms","age":42,"sex":"male","unit":"kg","dominantHand":"right","rightReading":52,"leftReading":48,"bodyMassKg":78,"forceData":"","forceUnit":"newtons","trialsData":""}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
