What a simulated Muay Thai match asked of the body

In a 2009 study, 10 Muay Thai athletes fought a simulated match wearing a portable gas analyser. Their oxygen uptake and heart rate stayed above the anaerobic threshold for the whole match. The anaerobic system surged in the first round, and from then on the aerobic system carried more and more of the work.

The authors concluded that Muay Thai leans hard on both energy systems, and that training should build each of them. The sessions below mix steady pad rounds with short, fast bursts for that reason.

This format suits anyone who trains kicks, knees, elbows and the clinch, whether or not they plan to fight.

The protocol

This timer rings a bell as each round starts and ends, warns ten seconds before each round ends, has a fullscreen key, and keeps the screen awake where the browser allows; it is free and needs no account. Keep this tab in front, because a browser may pause the sound of a tab you cannot see.

Sessions to try

These are our suggestions. Where one follows a published source, that source is cited under it.

Six palettes, and a phase keeps its meaning in all of them

The same four grounds, drawn six ways. Each is solved so that get ready, work, rest and done stay apart, and so the clock stays readable from across a gym. Pick one and the whole page turns with it; this browser remembers the choice.

The app

The same clock, in your pocket

Bursta is being finished for phones. Android comes first and iPhone after it. It is the timer you have above, built as an app: the same reading of the wall clock every frame, so a locked screen, a phone call or a backgrounded app does not make it drift.

  • It keeps sounding with the screen off

    The bell lands with the phone locked in your bag and your music still playing. A page in a tab cannot do that.

  • Your own workouts, and a record of them

    A builder, a library you name and reorder, a history that fills itself in, and a calendar with repeats and reminders.

  • Made to be read while you are breathing hard

    Six palettes, five text sizes, and the phase in the colour of the whole screen. English and Ukrainian.

Soon on Google PlaySoon on the App Store

The Bursta app on a phone, on its history screen: a calendar of August 2026 with a filled dot on every day trained: Monday, Wednesday, Friday, Saturday. Under it, the sessions themselves, each dated and timed: Boxing, 3 min, at 08:11, 8 of 8 rounds, 31:00; Tabata at 18:14, 8 of 8, 3:50; HIIT 40/20 at 18:49, 10 of 10, 9:40.
