EPISODE 48 - Concussions, Brain Health and Ketogenic Diets w/ Dr. Paul Hrkal ND

In episode 48, Dr. Bubbs dives into the topic concussions with expert Dr. Paul Hrkal ND, who discusses the pathophysiological root causes, if clinical recovery and cessation of symptoms means you’re ready to play, biomarkers for diagnosis, specific dietary interventions, as well as supplements to support brain health and concussion recovery and more. Lots of great insights and actionable tips here from Dr. Hrkal!

Lay-Ups In This Episode

  1. A mild traumatic brain injury is classified as a concussion.
  2. The root cause of concussions can be due to soft tissue injury, metabolic or blood flow restriction, persistent inflammation, bio-psychosocial factors, etc.
  3. A ketogenic diet may be beneficial for recovery from concussion.

Performance Tips From This Episode

  1. Supplements to consider for concussion support include fish oils, curcumin and creatine (and possibly exogenous ketones).
  2. Caloric restriction can help calm low-grade inflammation and microglial hyper-activation.
  3. Clinical recovery (no symptoms) does NOT mean full physiologic recovery.

EPISODE 45 - Epigenetics, MTHFR Gene & Potential Dangers of Folic Acid w/ Dr. Ben Lynch

In this episode, Dr. Bubbs interviews epigenetics expert Dr. Ben Lynch, who dives into the emerging field of epigenetics, outlining how the environment impacts how your genes are expressed. Dr. Ben discusses the MTHFR gene, responsible for producing the rate-limiting enzyme in the folate pathway, and the implications on your health and performance. He shares insights on methylation and its role in optimal heath, as well as highlighting the dangers of excess folic acid, efficacy of different types of supplemental folate, and most importantly how to make sense of genetic tests.

Lay-Ups From This Episode

  1. Leafy greens are an ideal source of dietary folate
  2. Supplemental folic acid is not naturally occurring in food and first synthesized in the 1940s.
  3. Genetic tests must be interpreted with caution. Always remember… “Genes load the gun, environment pulls the trigger.”

Performance Tips In This Episode

  1. Supplemental folinic acid is highly beneficial for supporting improved energy levels.

  2. Dairy antibodies, methotrexate, low methionine (amongst other thigns) block intermediaries in the folate pathway.  
  3. Optimize.me – “Plus One” helps to support creativity in the morning and productivity in the morning.

EPISODE 44 - Physical Development, Managing Athlete Recovery & Building Buy-In w/ Josh Bonhotal

In episode 44, Dr. Bubbs sits down with Josh Bonhotal, Director of Strength & Conditioning for the Purdue Boilermaker men's basketball team, Big 10 conference champions in 2017. In this episode, Josh talks about how he got started in Strength & Conditioning, lessons learned from working with Al Vermeil and the Chicago Bulls, how he prepares his guys in the off-season, the importance of solid nutrition & sleep fundamentals with young athletes, things to consider in-season to keep the team fresh and of course, perhaps the most important area, how to build buy-in and build relationships with players to really propel their success. Great, practical tips and insights here from Josh.

Lay-Ups In This Episode

  1. Off-season – train general capacities, build maximal strength and speed development. (rather than a focus on conditioning)
  2. In-season – Build the “repeatability” of those qualities
  3. What is an athlete’s “trainability” – how do they control movement and how is their posture. 

Performance Hacks From This Episode

  1. Match up qualities in the weight room with qualities trained on the track or playing field.
  2. Player interactions, outside of the use of technology, are key in forming player bonds.
  3. Prioritize how athlete moves, rather than how much they move, to be able to drive maximal long-term gains.

EPISODE 36 - Sleep, Behaviour & Your “Body Clock”: Achieving Your Performance Potential w/ Dan Pardi MS

In this episode, Dr. Bubbs sits down with sleep and behaviour expert Dan Pardi MS and CEO of HumanOS.me to talk about the latest insights on sleep and circadian biology, the internal cellular “clocks” in your body which control sleep, recovery and overall performance. Dan dives into the latest research on sleep duration and common roadblocks to high-quality sleep, he discusses how “food timing” dramatically impacts your circadian rhythms and weight gain, highlights how melatonin is a “timing” hormone (and not a sleep hormone) and shares his favourite tips for overcoming jet lag and circadian disruption. Dan shares a ton of simple, actionable tips to upgrade your mental and physical performance.

Lay-Ups – Sleep & Circadian Biology

1)   National Sleep foundation suggests you get 7-9 hours of sleep per night

2)   Exposure to morning light, activity and caffeine are all effective at setting your daily circadian rhythm or “body clock”

3)   Lack of sleep increases cravings, particularly for higher carb (and fat) foods

Performance Hacks – Sleep & Circadian Biology

1)    Employ the “colour shift” at night on your computer (not just night shift) to minimize negative impact on sleep quality

2)   Melatonin - 0.3-0.5mg dose when sun goes down when trying to reset circadian rhythm and support deep sleep

3)    Lumos Tech eye mask – helps to accelerate how quickly you can shift circadian rhythm when travelling across time zones

About Dan Pardi

EPISODE 6 - Coffee: Caffeine, Your Genes & Performance Effects w/ Nanci Guest

In this episode, Dr. Bubbs is joined by expert Nanci Guest PhD (cand) to talk all things coffee and caffeine, such as: new findings on "fast" vs. "slow" caffeine metabolizers, impacts on performance (and which group has negative effects!), whether to choose supplements or coffee for elite performers and how your genes influence all of these parameters. As usual, check out my "Lay-Ups' and "Performance Hacks" below.

"Lay-Ups" in This Episode (easy, simple, actionable takeaways)

1) Drink no more than 2 cups of coffee per day, before noon, to reduce your risk of CVD.

2) 50% of people are slow "caffeine metabolizers", meaning caffeine levels in the body take 8-10 hours to drop by half. Slow metabolizers may not feel "stimulated" but the caffeine is still blocking the "calming" effect in their body.

3) For the general public, coffee before training is all you need (save your money on "pre-workout" caffeine supplements).

Caffeine "Performance Hacks" from This Episode

1) The most effective dose of caffeine is 3-4mg/kg bodyweight (there's no additional benefit once dose is greater than 5mg/kg).

2) 10% of population are "ultra-slow" metabolizers and will have WORSE performance when they consume caffeine before training.

3) The more elite the athlete, anhydrous (i.e. supplemental) caffeine is ideal because the caffeine concentration in coffee is highly variable.

Coffee Talk: What does Nanci herself drink?

EPISODE 4 - Sleep Performance: How Things Go Wrong, Impacts on Performance and Habits of Highly Successful People w/ Dr. Amy Bender

In this episode, Dr. Bubbs takes a deep-dive into all aspects of sleep with expert Dr. Amy Bender PhD. Amy discusses the benefits of "light box" therapy in the morning, tips to offset the blue light from devices in the evening, "cognitive reshuffling" and "4-7-8" breathing to increase parasympathetic tone and help you unwind and fall asleep, as well as the controversial "nap-uccino" that seems to be gaining in popularity. Dr. Amy drops a lot of knowledge bombs in this episode... Enjoy!

"Lay Ups" in This Episode (easy, simple, actionable takeaways)

1) Get exposure to morning light (outdoors) for 10-15 minutes during winter months.

2) Avoid blue light 1-2 hours before bedtime from phones, iPads, computers (and turn the lights down in your house).

3) If drinking alcohol, do so earlier in the evening rather than right before bed to minimize impact on sleep.

Sleep "Performance Hacks" from This Episode

1) Introduce light box therapy to trigger circadian rhythms in the morning during winter.

2) Use "4-7-8" breathing technique to trigger parasympathetic relaxation response (i.e. inhale 4 seconds, hold for 7 seconds, exhale for 8 seconds).

3) Limit naps to 20-minutes on game days.
