Dr. Shawn Arent, an expert in exercise science and nutrition, discusses various interesting topics in this podcast. These include the importance of data in training, debunking misconceptions about aerobic exercise, the exercise metabolome, the concept of non-responders, the role of nutrient timing, a comparison of time-restricted feeding and chronic caloric restriction, the commonalities of tactical athletes, and an analysis of useful and ineffective supplements.
Combining Tiaquin and Diemine with caffeine can improve cognitive and physical performance in tactical athletes.
Tactical athletes have commonalities in job demands, such as sustaining vigilance and cognitive abilities, which can be addressed through specific training strategies.
Incorporating both aerobic and resistance exercise can lead to positive outcomes, and nutrient timing after exercise is crucial for optimizing glycogen replenishment and muscle protein synthesis.
Deep dives
Effects of Tiaquin and Diemine on Tactical Athletes
The study examined the effects of Tiaquin and Diemine in combination with caffeine compared to all caffeine and a placebo on tactical athletes. The participants engaged in a vigilance task, a physical movement task, and a target task to assess their performance. The study also measured blood pressure and hemodynamic responses. The results showed that the Tiaquin and Diemine combination, along with caffeine, led to improved performance in target acquisition, reaction time, and accuracy compared to the other groups. The study suggests that this combination may have potential benefits for tactical athletes in enhancing their cognitive and physical performance.
Defining Tactical Athletes
Tactical athletes encompass a range of professions such as police officers, firefighters, and military personnel. While there are physiological differences, there are commonalities in their job demands, including sustaining vigilance, quick response, power and coordination, and cognitive abilities. By identifying these underlying components, it is possible to refer to them as tactical athletes and develop training strategies that address their specific needs within their respective professions.
Intermittent Fasting and Performance
Intermittent fasting, specifically time-restricted feeding, has gained popularity, particularly for its potential benefits in weight loss. However, the literature suggests that there is nothing inherently magical about intermittent fasting for performance or fat loss. Some studies indicate that skipping breakfast may negatively affect performance later in the day, even if caloric intake remains the same. It is important to consider individual goals, training schedules, and the timing and composition of meals to optimize performance and recovery for tactical athletes.
Reaping the Benefits of Both Aerobic and Resistance Exercise
The podcast highlights the importance of combining both aerobic and resistance exercise for optimal results. While there may be differences in individual preferences and genetic factors, the overall consensus is that participating in both forms of exercise can lead to positive outcomes. The speaker also references the potential benefits of exercises like rowing and crossfit workouts, which incorporate elements of both aerobic and resistance training. Ultimately, the key takeaway is that individuals don't have to be limited to one type of exercise and can see benefits from incorporating both into their routine.
The Significance of Nutrient Timing and Supplement Performance
The podcast discusses the concept of nutrient timing and its impact on exercise performance and recovery. The speaker emphasizes the importance of consuming nutrients, particularly carbohydrates and protein, following exercise to optimize glycogen replenishment and muscle protein synthesis. While studies on specific nutrient timing supplements like caffeine and creatine are mixed, the overall consensus is that timing nutrient intake after exercise can have positive effects. Additionally, the podcast touches on supplements that may not live up to their hype, such as testosterone boosters and adaptogens, while highlighting the potential benefits of others, including beetroot, sodium bicarbonate, and fish oils.

He is also the Director of the USC Sport Science Lab. His research focuses on the relationship between exercise, nutrition, and stress and the implications for health, performance, and recovery. Dr. Arent is a Certified Strength and Conditioning Specialist with Distinction with the National Strength & Conditioning Association (NSCA), and a Fellow in the American College of Sports Medicine (ACSM), the International Society of Sports Nutrition (ISSN), and the National Academy of Kinesiology (NAK). He is also the immediate past-president of the ISSN. He was recognized as the 2017 Outstanding Sport Scientist of the Year by the NSCA, was awarded a Lifetime Service Recognition by the US Army 3-314th Field Artillery Thunder Battalion (the first such award given to a civilian), and he received the 2016 Directors Award for Scientific Excellence. He has received grant funding from the DoD, NIH, RWJF, and various industry sources. Additionally, he has worked with USSOCOM as well as teams and athletes in the NHL, MLB, NBA, NFL, US Ski and Snowboard, the US Soccer Federation, and a number of teams at the youth, high school, and collegiate levels. A former Division I college athlete and national champion, he refuses to believe he’s washed up even though his body likes to remind him otherwise.
