Onus Athletics

There are two reasons to put heat into a training. The first one is the more obvious one, and that is preparing for a hot race. The more interesting one is for a training effect - and that's what this episode is all about.Heat puts a load on the circulatory system, because your body has to work to keep its core temperature under control. That load drives adaptations, and some of them may help you run better in any conditions, including cool ones. In this episode I work through what actually happens - to your plasma, your stroke volume, your haemoglobin - then go through the evidence study by study, and finish with how to fit heat into a real training week without wrecking the running that matters more.To find out more and get in touch, visit onusathletics.com

Where did the interval session come from, and what does it actually do? In this episode of the Onus Athletics podcast, Connor follows it back more than a hundred years, to sprinters at the end of the 1800s, through a boxing manual, a Finnish handbook for training horses, a German coach and his star runner, and two labs, one in Freiburg and one in Stockholm, to what the science now says about the three things you can change in a session: the recovery, the length of the rep, and how fast you run it.It’s also the story of the rest between the reps. At first nobody planned it, then coaches timed it, then they controlled it by the pulse, and in 1959 two doctors in Freiburg argued that the rest was where the training actually happened.
