It tackles fundamental questions, like what genetic and metabolic adaptations occur with vigorous exercise and how it can contribute to combating heart's age-related changes. We also unpack how these rigorous exercises affect glucose transport, mitochondrial health, and brain health at an intricate level. Lastly, it introduces practical applications like the Norwegian 4x4 interval training protocol, the benefits of "exercise snacks," and how to incorporate vigorous-intensity exercise into everyday life.</p> <p><strong>In this episode, I discuss:</strong></p> <p><strong>(00:00)</strong> Introduction</p> <p><strong>(04:34)</strong> What differentiates "vigorous" from "zone 2" training</p> <p><strong>(08:34)</strong> Ties between VO2 max & life expectancy</p> <p><strong>(11:55)</strong> Why zone 2 training doesn't guarantee VO2 max improvements</p> <p><strong>(14:17)</strong> How to balance zone 2 training & vigorous-intensity workouts</p> <p><strong>(16:17)</strong> Why the Norwegian 4x4 protocol may improve your VO2 max</p> <p><strong>(19:35)</strong> Evidence-based methods to estimate VO2 max outside a lab.</p> <p><strong>(22:33)</strong> What it takes to reverse 20 years of heart aging: a two-year protocol</p> <p><strong>(28:24)</strong> HIIT and type 2 diabetes – how vigorous exercise can reduce risk.</p> <p><strong>(29:38) </strong>The mitochondria argument: HIIT vs. Zone 2 – which intensity is better?</p> <p><strong>(32:09)</strong> Rethinking the 80-20 rule for everyday exercisers (less zone 2, more effort)</p> <p><strong>(35:18)</strong> The role of high-intensity workouts in enhancing mitophagy</p> <p><strong>(38:03)</strong> Why lactate accumulation from higher training intensity benefits the brain</p> <p><strong>(40:28) </strong>Why the "glucose sparing" effect of lactate benefits brain injury and aging</p> <p><strong>(43:26) </strong>The unique BDNF benefits of high-intensity exercise: the lactate advantage</p> <p><strong>(44:42) </strong>The angiogenic effects of VEGF on the blood-brain barrier (in response to lactate)</p> <p><strong>(46:58) </strong>The greater the exercise intensity, the greater the myokine release</p> <p><strong>(49:48) </strong>How physical activity affects death risk in breast & colorectal cancer survivors</p> <p><strong>(50:56)</strong> How vigorous aerobic exercise kills circulating tumor cells</p> <p><strong>(52:36)</strong> Why exercise reduces depression and neurotoxicity (kynurenine mechanism)</p> <p><strong>(54:13)</strong> The surprising power of "exercise snacks" against mortality</p> <p><strong>(1:01:36)</strong> Download "The Cognitive Enhancement Blueprint" at <a href="https://bdnfprotocols.com?utm_campaign=vig_ex_podcast&utm_medium=podcast&utm_source=podcast_description"> bdnfprotocols.com</a> </p> <p><a href="https://youtu.be/YXl1evV_spo?si=G8ZHM1dbw2ua88xK">Watch this episode on YouTube</a></p> <p><a href="https://www.foundmyfitness.com/episodes/how-vigorous-exercise-improves-cognition-longevity?utm_campaign=vig_ex_podcast&utm_medium=podcast&utm_source=podcast_description"> Show notes are available by clicking here</a></p> <p dir="ltr">Get the latest distilled information straight to your inbox several times per month: <a href="https://www.foundmyfitness.com/newsletter?utm_campaign=vig_ex_podcast&utm_medium=podcast&utm_source=podcast_description"> https://www.foundmyfitness.com/newsletter</a></p> <p dir="ltr">Become a FoundMyFitness premium member to get access to exclusive episodes, emails, live Q+A's with Rhonda and more: <a href="https://www.foundmyfitness.com/crowdsponsor?utm_campaign=vig_ex_podcast&utm_medium=podcast&utm_source=podcast_description">https://www.foundmyfitness.com/premium</a></p> <p dir="ltr">Learn more about our premium podcast, The Aliquot: <a href="https://www.foundmyfitness.com/aliquot?utm_campaign=vig_ex_podcast&utm_medium=podcast&utm_source=podcast_description"> https://www.foundmyfitness.com/aliquot</a></p>
Actionable Insights
1. Prioritize Consistent Aerobic Exercise
Engage in any form of aerobic activity that resonates with you and can be consistently integrated into your routine, as consistency and habit formation are key for long-term benefits and sustainability.
2. Improve VO2 Max for Longevity
Strive to improve your VO2 max, especially if starting from below average, as even small increases are associated with significant increases in life expectancy and reduced mortality risk.
3. Reverse Heart Aging with Vigorous Exercise
Engage in consistent aerobic exercise with a high proportion of vigorous intensity (e.g., 5-6 hours/week with significant Zone 3 and weekly Norwegian 4x4 protocol) for two years to potentially reverse age-related heart changes.
4. Implement Norwegian 4x4 Protocol
Perform four 4-minute intervals at 85-95% of your max heart rate, followed by 3 minutes of light recovery (Zone 1 exercise) between each interval, repeating this cycle four times to significantly improve VO2 max.
5. Target 80%+ Max Heart Rate
Aim to reach at least 80% of your maximum heart rate during exercise to specifically target and maximize brain benefits, including enhanced neuroplasticity and neurogenesis.
6. Combine HIIT and Zone 2 Training
Incorporate both high-intensity interval training (HIIT) and moderate intensity Zone 2 training into your routine to achieve a more well-rounded approach to fitness and cover all physiological adaptations.
7. Add Vigorous Exercise if Non-Responsive
If moderate intensity exercise doesn’t significantly improve your VO2 max, incorporate vigorous intensity exercise like HIIT to stimulate physiological adaptations and achieve greater cardiorespiratory fitness gains.
8. Half of Workouts Vigorous for Committed Exercisers
If you’re a committed exerciser (3-5 days/week), dedicate about half of your total exercise time to vigorous intensity, aiming for at least 80% of your maximum heart rate, to optimize VO2 max and brain benefits.
9. More Than Half Vigorous for Casual Exercisers
If you exercise 2-3 times a week, spend more than half of that time engaging in vigorous intensity exercise to maximize fitness gains and adaptations within a shorter period.
10. Practice VILPA Daily
Integrate vigorous intermittent lifestyle physical activity (VILPA) into daily routines, such as sprinting up stairs instead of walking, for 3-4 minutes a day to achieve significant reductions in overall mortality risk.
11. Incorporate Exercise Snacks
Integrate short bursts of vigorous intensity exercise (e.g., jumping jacks, air squats, burpees) throughout the day, especially before or after meals, to improve blood sugar control and overall metabolism.
12. Boost Cognition with Exercise Snacks
Incorporate short exercise snacks (e.g., 2-10 minutes of HIIT every couple of hours) into your day to immediately increase blood flow to the brain, enhance mood, and improve cognitive function.
13. Break Sedentary Time with Exercise Snacks
Use exercise snacks to break up prolonged periods of sitting and sedentary behavior, which can reduce cancer risk, lower the risk of premature death, and provide various health benefits.
14. Stay Active for Cancer Prevention/Survival
Engage in any level of physical activity, both before and after a cancer diagnosis, to significantly reduce the risk of dying from cancer and all-cause mortality.
15. Increase Blood Flow to Combat Cancer
Engage in exercise with increased intensity and duration to boost blood flow, which creates shearing forces that can kill circulating tumor cells and improve cancer survival outcomes.
16. Boost Myokine Release with Intensity/Duration
Increase the intensity and/or duration of your exercise sessions to maximize the release of myokines from muscles, which have anti-inflammatory, anti-cancer, and metabolic benefits.
17. Estimate VO2 Max with Cooper Test
Perform the 12-minute run/walk (Cooper) test on a flat surface, covering as much distance as possible, then use the provided formula (distance in meters - 504.9) / 44.73 to estimate your VO2 max and track improvements.
18. Try One-Minute On/Off HIIT
Execute one minute of exercise at your highest sustainable intensity, followed by one minute of recovery, repeating this pattern 5-10 times for approximately 25 minutes to effectively improve VO2 max.
19. VILPA Benefits Non-Exercisers
Even if you don’t engage in formal exercise, incorporate VILPA (e.g., short bursts of high-intensity activity during daily tasks) to achieve significant reductions in mortality risk.
