Basketball conditioning zones in bpm with a shuttle drill planner, heart-rate restart cue and one-minute recovery score.
This calculator turns your age or a measured maximum heart rate into five basketball conditioning zones in beats per minute, from shooting-day recovery work up to suicides and 17s, and shows the live-play band of roughly 85–90% of maximum that match analysis reports for time on court. It also plans a shuttle block — repetitions, work and rest seconds, work-to-rest ratio and total time — with a heart-rate restart cue so the next rep begins when you have actually recovered, and scores your one-minute heart rate recovery against the 12 bpm threshold used in the cardiology literature.

Each zone names the basketball work that lands in it, from shell drill to full-court live play.
The restart cue converts a percentage of maximum heart rate into a real bpm number to wait for.
One-minute heart rate recovery is calculated and compared against the published abnormal threshold.
Live play typically averages about 85–90% of maximum heart rate, with players spending most of their court time above 85%. For a 25-year-old with a Tanaka maximum of 191 bpm, that band is roughly 162–171 bpm.
Long enough for heart rate to fall back to around 70% of maximum before the next repetition, which for most players is 45 to 90 seconds after a 30-second shuttle. Using a heart rate cue instead of a fixed clock keeps every rep at the intended quality as fatigue builds.
A fall of more than 12 beats per minute in the first minute after stopping is the normal response; 12 bpm or less was classed as abnormal in the Cleveland Clinic cohort that established the marker. Well-conditioned athletes often drop 25 to 40 beats. A single low reading is not a diagnosis — repeat it rested and raise it with a doctor if it persists.
Heart rate takes 30 to 60 seconds to catch up with an effort, so a five-second closeout or a single fast break ends before the number moves. Use heart rate to judge overall session load and recovery between reps, and judge short bursts by output — shot quality, sprint times and how fast heart rate falls afterwards.
