Summary

Andy King, PhD, is an exercise physiologist at the Australian Catholic University. Andy joins us to discuss the science and application of hydrogel products like Maurten and SiS Beta Fuel. Do they work, how do they work, and is it worth paying the premium compared to regular sports nutrition products? IN THIS EPISODE YOU'LL LEARN ABOUT: -What are hydrogels, and how are they different from regular gels? -The theory behind how hydrogels could work to improve endurance performance -What does the science say? Do hydrogels improve endurance performance, metabolic markers, or gastrointestinal symptoms compared to regular gels? -Practical recommendations: is it worth it to use hydrogels? -Glucose and fructose - is there an ideal ratio for sports nutrition products? -How to maximise carbohydrate intake (e.g. taking in 120 g/h of CHO) SHOWNOTES: https://scientifictriathlon.com/tts333/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/ SPONSORS: Precision Fuel & Hydration - Optimise and individualise your fueling and hydration strategy using the free online Sweat Test and Quick Carb Calculator on precisionfuelandhydration.com.

0:00.0	The Traathlon Show 333.
0:04.8	Hey, what's up, everybody?
0:19.3	Welcome back to another episode of That triathlon show, the podcast presented by
0:24.1	Scientific Triathlon.com.
0:26.6	I'm our host Michael, and on today's episode, I interview Dr. Andy King.
0:30.2	Andy is an exercise physiologist at the Australian Catholic University, and he joins us today
0:34.9	to discuss the science and application of hydrogeal products,
0:38.2	for example, the likes of Morton and SIS beta fuel.
0:42.6	Do they work?
0:43.5	How do they work?
0:44.3	And is it worth paying the premium compared to regular sports nutrition products?
0:47.7	Those are questions we'll try to answer in this interview.
0:50.7	But before that, big thanks to our sponsors, precision fuel and hydration.
0:54.6	Precision fuel and hydration have two new and exciting products that I want to highlight today. First, they
0:59.7	have the PF-90 gel, which is affectionately known as a jumbo gel. It has 90 grams of carbohydrate
1:06.3	in it and a resellable cap. So it's a great product for carrying efficiency because having even one
1:12.0	or just a couple of these gels can go a pretty long way even on your longer workouts.
1:17.5	The other new product is the PF-32 which you can get in two flavors either the original
1:23.2	which is a mild and neutral flavor or in a mint and lemon flavor.
1:27.1	These chews are great alternatives to gels or sport drinks,
1:30.2	especially during longer workouts at lower intensities,
1:32.9	because they can feel a bit more satiating and satisfying than the alternative.
