We’ve got all the buzz words teed up for this episode as Wes dives into the rationale and set-up of his study on CrossFitters and Keto diets, impacts the 12-week nutrition strategy had on the their performance (e.g. 1-RM squat and 400m sprint), body composition, and blood markers. Wes also discusses some limitations of the study and things for the coach or athlete to consider before diving into this approach, as well as sharing his thoughts on supplementation after years in the research side of things. All this and much more!

S2 EPISODE 26 - Sprinters, Hockey Players & Relative Energy Deficiency in Sport (RED-S) w/ Jen Sygo MSc RD

Season 2 Episode 26, Dr. Bubbs interviews Jen Sygo RD MS, Performance Nutritionist for the NBA’s Toronto Raptors and Athletics Canada to talk relative energy deficiency in sport (RED-S). In this episode, Jen will discuss her recent study on REDS in female sprinters, share primary red flag symptoms and secondary ones to watch out for, and talk about the common misconception of low energy availability in power and sprint sports, and the consequences on performance. Jen also shares new insights on within day energy balance, the difficulties in assessing energy intake and expenditure, when athletes are “circling the drain” and share her experience working with NHL hockey players during the grueling playoff run and fueling in compressed competition schedules. 

Lay-Ups In This Episode

1)    RED-S is Relative Energy Deficiency in Sport is the result of insufficient caloric intake and/or excessive energy expenditure.

2)    ‘Energy availability’ (EA) refers to the amount of energy left over and available for your body’s functions after the energy expended for training is subtracted from the energy you take in from food.

3)    Low Energy Availability is not just a problem for females or endurance athletes, it can impact all athletes.

S2 EPISODE 25 - Workload Monitoring & Player Development in the NBA w/ Ramsey Nijem MSc

Season 2 Episode 25, Dr. Bubbs interviews Ramsey Nijem MS, the Head Strength and Conditioning Coach for the NBA’s Sacramento Kings. In this episode, Ramsey will discuss workload monitoring in team sport, the acute to chronic ratio and the relationship that exists between workload, fatigue, and injury. He’ll share his insights on the fine balance between pushing athletes too hard and not hard enough, how to balance out workloads in team sports when players are logging vastly different minutes, as well as navigating the inter-individual responses to training and why some players can tolerate much more than others. Ramsey also talks about the role of sleep and nutrition in recovery, highlights some of the fundamental exercises he uses with the Sacramento Kings players and much more. 

Lay-Ups In This Episode

1)    Workload monitoring is the practice of tracking data to assess an athlete state of “readiness” for the next game or practice.

2)    Internal training load is how the athletes “respond” to training; the physiological or psychological stress during exercise such heart rate, rating of perceived exertion, heart rate variability, etc.

3)    External training load is what the athletes “do”; the speed they’re moving at, the distance they cover, the accelerations and decelerations, etc.
