Dear Performance Nutrition Leaders,
This week: heat adaptation, hiring news, and lessons from applied performance nutrition.
💡 LATEST RESEARCH
Research and applied practice work to different clocks.
Research is careful and considered, built on review and replication, while applied practice has to act in real time because a Saturday fixture will not wait.
Dr Andy Kasper, now more than a decade into Premier League delivery, currently at Newcastle United, has spent his career with a foot in both.
Speaking inside the Performance Nutrition Network, Kasper walked practitioners through a PhD that grew out of his applied work, writing papers to answer the questions the day job kept throwing up.
The framing device was the Paper-2-Podium Matrix, a way of scoring a study on its context, design, feasibility and risk before deciding when to act on it.
Timing cuts both ways, with performance on offer for those who move at the right moment, and real cost to the athlete for those who move on evidence that is not ready.
From there Kasper moved through the tools we lean on daily, showing how far apart experienced and inexperienced nutritionists were when estimating energy intake from a photograph, and why he now treats snap-and-send with caution.
On supplementation he returned to a familiar tension, the food first approach that quietly becomes food only, and how that caution can cost an athlete the omega-3 or creatine dose they were never going to get from the plate.
His work on oral nicotine, the "You Snus You Lose" commentary written with Graeme Close, was picked up and turned into an infographic now used across football, a neat example of research reaching the changing room.
The takeaway was less about any single nutrient and more about the person delivering it, knowing your players, being present at mealtimes, and earning the buy-in that no framework can hand you.

💡PERFORMANCE TECH
Every marginal gain against heat is getting a look.
CoreCtrl is made by truefuels, the endurance nutrition brand co-founded by Olympic triathlon champion Alistair Brownlee alongside performance nutritionist Nigel Mitchell.
truefuels CoreCtrl is distinct from the hydration and fuelling products it sits alongside. Reporting this week (via The Guardian) has England players using it to help cope with extreme World Cup heat.
The formula centres on a high dose of L-Taurine (4,000mg), which truefuels says needs eight days of daily loading to reach levels where it affects sweat response and core temperature rise.
Supporting it: potassium (300mg), calcium (120mg) and magnesium (60mg) for muscle and nervous system function under heat stress, Himalayan rock salt for sodium, and black pepper extract (piperine) included specifically to improve absorption of the other actives rather than for its own effect.
CoreCtrl is Informed-Sport certified.
The use case is the important detail: this is not a raceday electrolyte mix. It's an eight-day daily protocol — one sachet in 500ml cold water — with the final dose on the morning of competition, positioned for endurance athletes (triathletes, marathoners, cyclists, HYROX) training or competing above roughly 15°C.
The planning requirement, and the price, are real considerations: $50 buys one 8-sachet box — a single protocol — with 16- and 32-sachet options for athletes or squads running it repeatedly across a season.
