What your heart rate says about an hour of padel
Padel does not feel like training until you look at the trace. An hour of it is a stop-start interval session, and the Apple Watch you are already scoring on is already measuring it.
Padel is intervals holding a racket
A padel point lasts a handful of seconds and then stops. Then it happens again, forty times a game. What comes out is a heart rate trace that spikes and falls all evening — much closer to an interval session than to a run, which is why judging the hour by how tired you feel at the end of it is usually wrong in both directions.
Because you are scoring from your wrist anyway, the watch is on you and awake for the whole session, and the trace lines up with the match. The set that went to a tiebreak looks nothing like the one you won 6-1.
Zones, fatigue, and the ratio that surprises people
Pelota keeps the time you spent in each of the five heart rate zones, from resting through to flat out, and shows how tonight's split compares with the last session. It follows the fatigue as it built, set by set, so a third set that fell apart has a shape rather than an excuse attached to it.
The work-to-rest ratio is the number most players find genuinely new. It says how much of the hour was actually work — which is rarely what it felt like, because the changeovers, the arguments about the score and the hunt for the ball behind the glass all count as rest.
How fast you come back down
The more interesting number arrives after the last point. Pelota offers a two-minute cooldown on your Apple Watch and measures how quickly your heart rate falls: the drop at sixty seconds and the drop at two minutes, plotted as a curve heading back towards your baseline.
Heart rate recovery at sixty seconds is one of the most validated markers of cardiovascular fitness in sports medicine, and unlike most fitness numbers it moves quickly when your fitness moves. Accept the cooldown once and it starts by itself after every session from then on. Measuring it needs a Pelota Pro subscription.
What to actually do with the numbers
Two of them are worth watching over a month; the rest is context. The first is the recovery drop. If the sixty-second number is getting bigger, your base fitness is moving, whatever the scorelines have been doing.
The second is the work-to-rest ratio read against how the session felt. An hour that felt brutal but was mostly rest usually means the intensity was fine and the legs were not. An hour that felt easy but was mostly work is how you end up sore on Wednesday without knowing why.
Zone time is best read as a comparison rather than a target. There is no correct zone distribution for padel — a social hour and a tight three-setter are supposed to look nothing like each other.
It belongs with the rest of your training
Everything the watch measures is written to Apple Health — heart rate, calories, steps, the workout itself — so Tuesday's match sits in the same record as your runs and your sleep instead of in an app of its own.
It works the same way for the hours that are not matches. Free Play measures the physical side of a casual hit with no score attached, and Practice does it for drill work, so a session still counts even when nobody was counting points.
What you need
An Apple Watch on watchOS 10 or later, paired with an iPhone on iOS 18.0 or later. Both apps come in one download and no account is needed to start.
Heart rate tracking works offline, in a basement court, with no signal at all. The app itself is free; the recovery measurement and the deeper analysis are part of Pelota Pro.
