In endurance sports, power is king. Just like on the bike, where power meters help guide your training and race strategy, measuring power in the water gives you a clear picture of how much effort you’re putting in–and how effectively you’re using it.
In the past, swimmers and triathletes haven’t had access to an easy, accurate way to measure power in the pool. But new tools, like eo SwimBETTER, are changing the game. eo SwimBetter is a wearable device that tracks how much power your hands produce in the water and how effectively that power moves you forward.
Why Power Matters in the Water
Not all swimming effort is created equal. You might be working hard, but is that effort actually helping you swim faster? With technology like eo SwimBETTER, you’ll find out.
It shows you:
- How much work you’ve done during that session
- How much of that work translated into effective propulsion
- How much energy was wasted due to poor technique
- What you can change to swim more efficiently
For triathletes, this is a game-changer. Less wasted energy in the swim means more in the tank for the bike and run.
Like Your Bike Power Meter – But for Swimming
With eo SwimBETTER, you can collect power data – just like you get from your cycling power meter – and upload it to TrainingPeaks to determine your:
Intensity Factor (IF): measure how hard you’re working relative to your maximum
Training Stress Score (TSS): track training load across all your sessions
Energy Expenditure: plan your fuelling and recovery
Just sync your eo SwimBETTER data with TrainingPeaks, and you’ll have a fully integrated view of your training across swim, bike, and run.
How eo SwimBetter Works
Swimming is more complex than cycling. Your hands aren’t fixed to a crank like your feet are on the bike. They move freely, and that freedom introduces inefficiencies–unless you know how to control it.
Here’s what eo SwimBETTER measures:
- Force: How much force your hands apply to the water
- Velocity: How fast your hands move
- Direction: how much of the power (force and velocity) you are generating is propelling you forward
By analysing these metrics, eo SwimBETTER helps you swim faster by:
- Avoiding wasted motion that burns energy without improving speed
- Maximising power along your body’s centre line
The following two charts show the change in propulsive power after using the feedback provided by eo SwimBETTER to modify and improve swim technique.
Get out of the Water Ready to Ride
In short, eo SwimBETTER helps you swim smarter. You’ll improve your technique, track your performance, and manage your training load, all with real, objective data.
It’s not just about swimming faster – it’s about conserving energy early in your race, so you arrive at the bike ready and still have plenty left for the run.
