Paris races: cardiac arrests spike in final kilometer

In this Spotlight, we run our eye and offer our insights on the world of sport, covering a range of sporting events. We start with the Six Nations, which went beyond the wire in a spectacular tournament that shows the health of "the product". We discuss the ongoing Cape Epic, where the pairs format throws up some pacing and tactical challenges for unbalanced teams. And we preview the year's first Monument, where Tadej Pogacar will have to test and challenge Mathieu van der Poel's durability and 5-min power to win the elusive title. We discuss the requirement for Pogacar and UAE to extend the efforts above FTP and even VO2max to climbs even before the Cipressa, in order to make van der Poel vulnerable to a five minute effort on the decisive Poggio climb.

Switching to running, we briefly discuss the remarkable 2:10 performance by Fotyen Tesfay in Barcelona, and why it's the de factor WR, but may be as questioned as the incumbent WR by Ruth Chep'ngetich. Another dramatic finish in Los Angeles, a marathon decided by 0.01s where the 'loser' went the wrong way, and didn't, apparently, take in a single gram of carbohydrates in the race.

While on the subject of dramatic finishes, recent research shows that the odds of a cardiac arrest are significantly higher in the final kilometer of running races (20km and half marathon). We compare that to triathlons, where the odds of cardiac arrests are way higher in the first part of the race, in the swim. We discuss the physiology and emotional reasons for these risk increases.

We then move into the resistance training space, to talk briefly about the American College of Sports Medicine's position stand on resistance training. It says what many people know, but challenges what a lot of people think, and the reaction has been enlightening!

And finally, a few short results and discussion points from around the world of sport, including an unprecedented reversal of an entire tournament result, and a rare "defeat" (on a technicality) for Johannes Klaebo in cross-country skiing
