Tabata Time Calculator
Compute total Tabata workout time: 8 rounds × (20s on + 10s off) by default. Configurable rounds, on, off, blocks.
Tabata protocol: 20s on / 10s off
The classic Tabata protocol is 8 rounds of 20 seconds at maximal intensity + 10 seconds rest = 4 minutes total. Designed by Dr. Izumi Tabata in 1996 with Japanese speed-skating athletes, the original study (Med Sci Sports Exerc) showed it simultaneously improves VO2max (aerobic capacity) and anaerobic capacity — a rare combination in such a short window. It's a canonical form of HIIT (High-Intensity Interval Training). Typical exercises: burpees, sprints, jump squats, mountain climbers, kettlebell swings. Frequency: 2-3×/week with a full rest day between sessions, since the intensity is genuinely maximal. Common alternatives: EMOM (Every Minute on the Minute), AMRAP (As Many Rounds As Possible), and the 30/30 ratio for less-trained beginners.
Applications and context
Widely used in CrossFit WODs, athlete conditioning when time is tight, residential HIIT routines, and military/firefighter physical preparation. Effective when the "all-out" intensity is real — at moderate effort it loses its physiological signature and becomes just another circuit.
FAQ
Is 4 minutes really enough? Yes, if the intensity is maximal — 170%+ of VO2max in the original study. Most "Tabata" videos online run at moderate intensity and are not real Tabata.
How many days per week? 2-3 sessions with a full rest day between. Daily Tabata leads to overtraining quickly.
Tabata vs HIIT in general? Tabata is a specific HIIT protocol (20/10 × 8). HIIT is the broader category including 30/30, 40/20, EMOM, AMRAP and other ratios.

Irrigation Time
Calculate the required irrigation time, t = depth ÷ application intensity, dividing the depth to apply (mm) by the system's application intensity (mm/h). The result, in hours, is how long the system (sprinkler, pivot, drip) must run to apply the desired depth. The application intensity must not exceed the soil's infiltration rate, or it causes runoff and erosion. Multiplied by the flow, it gives the water volume; combined with the number of sectors, it sets the total irrigation time of the area. It is a routine calculation in daily irrigation management. Enter the depth and the application intensity.
