If you can measure it in sport, there is likely a ready-made tool waiting.

How accurate are the sports and fitness calculations?

Each tool applies the official or widely accepted formula for that metric — such as the U.S. Army's ACFT scoring tables and standard IAAF athletics formulas. Results are estimates intended for training guidance. These calculators are NOT medical advice; consult a qualified healthcare professional before making significant changes to your training load or nutrition plan.
