🎉 I am proud to announce the release of lactater version 1.0.0

lactater is my open-source R package for analysing lactate thresholds. This release covers the whole workflow: record the test, estimate the thresholds, check how much to trust them, build training zones, and hand the athlete a report.

Which threshold method should you use, and how much can you trust the number? This release is built around those two questions.

What's new:

→ Ten method families in one call: Log-log, OBLA, Bsln+, Dmax and its variants, LTP, LTratio, IAT, Stegmann, Keul and Simon. Each one is explained with its evidence. https://t.co/V9txf8n6eo

→ How sure are we? Confidence intervals, checks on the test, and a look at which stage moves the result. https://t.co/G1Xz9BL4ua

→ Training zones from LT1 and LT2, with heart rate and RPE for each zone. https://t.co/AcZOyRpjWD

→ Is the change real? Compare two tests against the test-retest noise of each method. https://t.co/vvI2FBWA7i

→ Race time predictions for running and cycling, or calibrate your own equation. https://t.co/tY2u7jGUki

→ A two-page report for the athlete or the coach. https://t.co/JWkJTp2kFb

→ A web form to record the test, and a guide to running a good one. https://t.co/tTFewICzLu
https://t.co/X3CoGQUxg5

→ A cheatsheet. https://t.co/MpIsEXeMgJ

It is free and open source. Install it with install.packages("lactater").

Thank you to everyone who reported issues and sent ideas over the years. If you use it in your lab or with your athletes, I would love to hear how it goes.

Now published! Our invited commentary on exogenous lactate as an endurance fuel is out today in @IJSPP_Journal.

Years of research, distilled into hypotheses worth testing. Thank you @borjammt and @adrian_science

I've coached over 30 Olympic gold medals.

I've worked with some of the greatest athletes in history.

Here are the lessons I wish more people understood:🧵

Delighted to see this one out in print now. Congratulations to my co-authors Giannis and great friend Argyris! 👏👏👏

In 2019, Jesse Faden entered the headquarters of the Federal Bureau of Control. What followed led to Jesse becoming the new Director of the FBC and helped her find her long-lost brother.

Periodising training around menstrual cycle phase is considered by some coaches, but a new review finds no evidence it is better than standard programming for strength or endurance athletes.

‘The head is in a race with the hands’.

It’s one of the easiest ways to help swimmers understand how they need to breathe effectively in butterfly.

First, the head needs to start coming up as soon as the arms start applying pressure with the pull.

If there’s a delay, swimmers are going to struggle to get the head up to breathe.

Second, the head needs to get back down in the water before the arms enter the water after the recovery.

If there’s a delay, swimmers are going to be creating more drag than they need to for longer than they need to.

And a mistake in one area is going to make a mistake more likely in another area.

It’s always a race.

The more swimmers can stay ahead of their arms when they breathe, the easier it will be to breathe effectively and the less likely it is that the breath will negatively impact the stroke.

Follow @andrewksheaff for more on the key skills in swimming, and how to improve them.

🚨💣 Jürgen Klopp addressing the German public during his introductory press conference as the new Bundestrainer:

“I’m not doing this job for myself. I’m doing it for you. I’m taking this job even though I’ve seen how you’ve treated Julian Nagelsmann. I’m taking it even though I’ve seen how you’ve treated Thomas Tuchel.

If you go after my family, I’m gone. If you think I’m rubbish, tell me to my face and I’ll leave immediately, without asking for any compensation.”
