Why Exercise Intensity Matters for Longevity | CrossFit for Health 2024

I recently had the privilege of presenting at the CrossFit Health Summit, where I described a constellation of factors that influence longevity - with special emphasis on the pivotal role of vigorous exercise throughout life.
Given that CrossFit has become almost synonymous with the type of intense, demanding workouts that are central to our discussion, the venue provided an ideal audience for exploring the profound impacts of this fitness approach.

🎯 Key Takeaways for quick navigation: 00:40 *🧠 Importance of High-Intensity Interval Training* - High-intensity interval training (HIIT) offers cognitive and mood enhancements in just 10 minutes. - HIIT boosts cognition through lactate production, which influences neurotransmitterrelease like norepinephrine and serotonin. - Studies indicate HIIT as a potent method for improving brain function and mood rapidly. 01:52 *💓 Significance of Cardiovascular Fitness for Longevity* - Cardiovascular fitness, especially measured by VO2 Max, correlates strongly with longevity. - Improving VO2 Max from below normal to elite levels can significantly increase life expectancy. - Each unit increase in VO2 Max is associated with an approximately 45-day increase in life expectancy. 06:56 *💪 Best Practices for Improving Cardiovascular Fitness* - The Norwegian 4x4 protocol, involving high-intensity intervals followed by recovery, is an effective method for enhancing cardiovascular fitness. - High-intensity interval training (HIIT) is superior to moderate-intensity exercise for increasing VO2 Max. - The 12-minute run test provides a practical estimation of VO2 Max for those without access to laboratory testing. 08:02 *🏋️‍♂️ Structural Heart Changes with Vigorous Intensity Exercise* - Vigorous intensity exercise can reverse structural heart changes associated with aging, making hearts more malleable and akin to those of younger individuals. - Ben Levine's study demonstrated significant heart structural improvements in sedentary 50-year-olds engaging in vigorous exercise. - These findings underscore the profound impact of vigorous exercise on cardiac health and aging. 10:24 *🩺 Cardiovascular Benefits Beyond Heart Health* - Vigorous intensity exercise significantly improves blood pressure, comparable to anti-hypertensive medications. - Lowering blood pressure through exercise reduces the risk of dementia and Alzheimer's disease. - Exercise's benefits extend to reducing circulating tumor cells, thus acting as a preventive measure against cancer metastasis. 11:18 *🧠 Cognitive Benefits of High-Intensity Exercise* - Lactate, produced during intense exercise, plays a crucial role in enhancing brain function. - High-intensity exercise triggers the release of neurotransmitters like norepinephrine and serotonin, improving focus, attention, and mood. - Even short bouts of high-intensity interval training can lead to significant cognitive improvements, attributed to lactate's influence on brain function. 16:53 *🍎 Metabolic Health and Exercise Snacks* - Exercise snacks, brief bursts of high-intensity exercise, improve metabolic health by reducing postprandial glucose response and increasing mitochondrial biogenesis. - These snacks, integrated into daily routines, significantly reduce mortality risk, even in individuals who identify as non-exercisers. - Implementation of exercise snacks offers a feasible and effective strategy for enhancing overall health and longevity. 21:16 *🏃 Importance of Avoiding Sedentary Behavior* - Sedentary behavior, such as prolonged sitting, is an independent risk factor for health issues, including cancer. - Incorporating short breaks of physical activity, termed "exercise snacks," can help break up sedentary time and mitigate its negative effects. 22:10 *💪 Muscle Preservation and Protein Intake* - Peak muscle mass occurs around ages 20-30, with a gradual decline thereafter, leading to muscle loss over time. - Skeletal muscle serves as a reservoir for amino acids, necessitating regular protein intake to prevent muscle breakdown. - Recommended protein intake levels may need to be revised upwards, especially for older adults, to maintain muscle health and functionality. 28:36 *🏋️‍♂️ Benefits of Resistance Training for Aging Adults* - Resistance training is crucial for maintaining and even recovering muscle strength and mass in older adults. - Even short periods (8-18 weeks) of resistance training, one to three times a week, can help regain lost strength from years of inactivity. - Older adults can benefit from resistance training with lighter weights, as long as the effort and volume are sufficient, offering a safer and effective approach to muscle preservation. 30:56 *🌡️ Deliberate Heat Exposure for Health* - Deliberate heat exposure, such as sauna use, induces physiological responses similar to moderate-intensity aerobic exercise, including increased heart rate and improved cardiovascular function. - Sauna use, along with exercise, can enhance cardiovascular fitness and other health markers, offering benefits for both active and less active individuals. - Heat shock proteins activated during heat exposure play a crucial role in preventing protein aggregation, potentially slowing muscle atrophy and offering neuroprotective effects. 41:51 *🧬 Exercise Intensity and Elite Athletes* - Elite endurance athletes, despite potential cardiovascular risks like coronary calcification, still exhibit lower cardiovascular death rates compared to non-athletes. - Coronary calcification risks may be relatively lower even with higher levels among elite athletes. - Endurance athletes demonstrate unique physiological adaptations that contribute to their overall lower risk of cardiovascular mortality. 42:48 *🧖‍♂️ Finish Saunas vs. Infrared Saunas* - Finish saunas and infrared saunas both provide benefits through mechanisms such as increased heart rate and elevation of core body temperature. - Finish saunas, operating at around 174 degrees Fahrenheit, offer robust benefits, including improvements in cardiovascular fitness and reduced dementia risk. - Infrared saunas work differently, requiring longer durations to achieve similar benefits, and may not provide the same cardiovascular improvements as traditional saunas. 47:20 *🌡️ Optimal Sauna Temperature* - The ideal sauna temperature typically ranges around 174 to 180 degrees Fahrenheit, with personal preferences varying. - While some may prefer temperatures up to 190 degrees Fahrenheit, caution should be exercised to avoid exceeding 200 degrees Fahrenheit, as it may lead to adverse effects. - Maintaining a temperature range below 200 degrees Fahrenheit appears to offer optimal sauna benefits without unnecessary risks.

[@FoundMyFitness]

My practical takeaway is that for high-intensity cardio work, the Norwegian 4x4 method is an excellent research backed protocol. The study you mention just gives us a frame of reference for increases in circulating BDNF in association with a measure of intensity, but I don't think it's useful to extrapolate as a prescription. To learn more about intensity work, listen to my interview with Dr. Martin Gibala at: foundmyfitness.com/episodes/martin-gibala

Isn't there reverse causation because only healthy, mobile, non-diseased people can engage in the vigorous exercise needed to increase VO2 max? So are we just saying that healthy people live longer? The authors of the discussed study admit that they don't know: "The degree to which high CRF preselects patients with lower mortality vs causes a reduction in mortality is not discernible from our study."

[@luzaguirre2830]

If we do the regular intense exercise then we can Become mobile, non diseased, healthy individuals

[@belle2263]

The issue in Australia is the saunas are rare not very common and the leisure centre will charge copious amounts of money to use the sauna. Some gyms have them but the membership is slightly higher. With the cost of living not very likely we will be able to have access to it here. I do have hot baths.

[@whiterabit09]

[@wiltonpt1]

The most longevous person I have had notice of was a russian man who worked in agriculture every day (low load , low intensity) and had to climb a hill on the way to work every day. Most longevous people belong in the older times. None of which seem that developed activities that would match these modern theories about longevity, yet their testament remains. Most of them were not even that active but had lived an active life with peace of mind and eat moderately. Its amazing how many theories and relationships we can articifially conjure up to explain something that was quite common back 200 years ago when deaths were mostly by infections.

[@TO-il3vc]

It is very possible that that same man would have lived even longer if he employed some of the strategies recommended in this new research. It is also likely that he did hours upon hours of low intensity manual labor each day, given the nature of agriculture. It is very difficult to recommend something like 5+ hours of exercise per day to a modern-day adult in a metropolitan area. Dr. Patrick's guidelines are realistic and actionable, that's why they're notable.

[@wiltonpt1]

@@TO-il3vc I know Rhonda personally and respect here. BUt the voice of science is not always the voice of realism. Science has for the past 80 years had to reword and take down enourmous amounts of its claims and hyperboles. Its scientism dressed in robes of enthusiasm. Reality teaches us differently. There are physiological limits to things, age is one. One variable cannot overturn a complext and philosophical mistery such as ageing and death. We were created for a garden for hours of activity....the benefits of that have never been replicated my a few hours of intense training in any machine. The model is the best we have, but our society has built many other ways which quite don't make it ....Therefore there is no one alive that can say," I implemented this theory" and here I am , 100 some years old. So , its good to ground ourselves in the observed past and in truth (ALETHEIA)

[@TO-il3vc]

@@wiltonpt1 i agree that humans are built for endurance rather than short bursts of high intensity activity, however i think its hard to measure and test such long periods of activity over so many years, thats why we don't hear about the benefits of low-intensity long-form exercise routines. Like i said above, Dr. Patrick's advice is actionable - something a normal adult could actually do. Most normal adults sitting at a desk for 9 hours a day simply do not have the time to do long-form exercise routines. I would also like to point out that what a human perceives as "realism" is merely in the eye of the perceiver. Perspectives, imperfect senses, biases, and emotions can all cloud that "realism". Science removes that subjective eye and makes things concrete.

[@wiltonpt1]

@@TO-il3vc I fully agree that exercise programs are necessary , actionable and mitigate the damage sustained by excessive inactivity and lack of physical stimulation. I don't argue the point. Adaptations in many exercise modalities are lost rapidly, and it requires keep doing this beyond retirement age, which also is not realistic for some. Exercise is also number 1 risk for MSK injury. As far as reality, the word in greek says it all. We don't build or imagine. Maybe in the perceptural world things can be argued but in physical fitness , number of years healthy or degenerative agains we don't get to pick our prefered reality. The word in greek is the same for truth. There are not Two truths regarding the same observable phenomone. We can still argue causality or other dimentions. People lived long lives back in the days.

[@warrenhenning8064]

Your claim is provably false. Life expectancies have increased over time, not decreased. A properly run scientific study is not "artifically conjuring" something up. Infections were but one of the many ways to die young 200 years ago. You neglected to mention disease, famine, war, death during child birth, etc.

[@lokeshvaishnav5808]

How you calculate the increase in the life expectancy?

[@scottk1525]

We need to pump the brakes on this obsession with VO2 max & HIIT until there's some interventional data showing causality, lest you make the exact same mistake as people who think improving grip strength will increase lifespan. Yes, both VO2 Max and grip strength are highly correlated to life expectancy, but it's possible (I'd say likely) that they're both just markers of overall good health, as opposed to causal (ie: healthier people have stronger grips, and only people that are already healthy can achieve a high VO2 max.)

[@myrtoashe]

But then you have the study showing improvements in the heart with a 2 year intervention. This suggests you get some benefit from exercise. That wasn't specifically about VO2 max, but it was most likely relevant to longevity.

[@scottk1525]

Regarding muscle preservation & RDA for protein intake. Does body fat come into play? If 2 people have the same amount of muscle, but one weight 30 lbs. more because of additional adipose tissue, does the person who weighs more still need to consume additional protein?

Some here have mentioned they know 90+ year old people who never excersized past highschool and are healthy and spry... My Dad died a few years ago from covid. He was 100 yrars old, and if not for covid would still be alive. He never intentionally excercized, but loved being active. I believe in what Rhonda is teaching. I have a friend who is 64 years old, 40 lbs overweight, borderline hypertension. We are just starting to ride bikes together. But, I think if she does not make healthy changes with more excersize. Her life expectancy around 10-15 years more. With weight loss and increased exercise she could add 5-10 years easy. We who are saved Christians will be raised together with Jesus Christ, and enjoy eternal life with Him forever! Those without this hope, only can hope to live longer in this life.

Would like to know what is realistic for 70

[@matthewcohen6339]

Do moderate exericse regularly, and high intensity once every couple of weeks. Because she's so obsessed with HIIT, she makes it sound like that's the only exercise you should do, but that doesn't work for us old-timers. Rhonda considers 50 to be old age, but when you're 70, 50 was the good old days when you could do anything LOL For high intensity session, I still do 20 minutes of regular moderate exercise to get warmed up, then maybe 10 minutes of intervals (30 secons of all-out effort, then 1 minute rest) then 5-10 more minutes of low-inensity to cool down.

@@jamesgordon8867 Keep doing what's working for you!

[@HSLSFirst]

Push as hard strength/cardio/HIIT as it is sustainable for you 5-6 days/ week. The more fit you are the more you can push. If you start from total sedidentary, you must start slowly just a few days per week and increase from there.

[@oliverteekahrealestatebrok6300]

Such precise claims. Your Methodology/rigour & numbers sited must be taken with a cautious lump of salt. Good intentions from this scientist tho!

[@GARIMITO]

Dr. Rhonda Patrick is neither an exercise scientist nor an endurance athlete. Low intensity or low heart rate training is superior to higher intensity training provided time is a non issue. 2.5 hours/week is not sufficient time for low intensity training. It needs to be at least 5 hours/week. High intensity training leads to burn out and injury. Follow Floris Gierman’s KZbin channel for better information.

[@jakubchrobry3701]

What if it's relatively easy for me to do 80% of my max heart rate? Why shouldn't I do that? I typically like to finish my lower rep weight training for legs with a set of 20 rep squats or leg presses. That's difficult and raises my heart rate. When I go to the bike after this, I can easily do 20 minutes of 80% max heart rate. If anything is going to injure me, it's my low rep (4-6) heavy squats. 80% of max heart rate on the bike almost feels like a cool down (I'm not saying I actually cool down, it's just easy) regarding effort. I'm 60 years old. My max heart rate is at least 180 bpm. I try to keep my bpm over 150 for twenty minutes.

[@GARIMITO]

@@jakubchrobry3701 so basically there are different methods for low heart rate training such as zone 2 or maffetone method. The maffetone method is 180-age for the top end of your goal heart rate. For your age, your goal heart rate is 110-120. If you can be in this heart rate zone for 10 hours a week (and the more the better), you’re going to make incredible progress. The top athletes do this. I recommend base building with this for 6 months before including any high intensity (at which time you can do the 80/20 rule with 20% of exercise being high intensity). It’s good to have a goal, so try a marathon or half marathon. Occasional high intensity training isn’t superior to low intensity training. The study she presented is disgraceful.

[@GARIMITO]

@@jakubchrobry3701 To answer your question, 80% of your max heart rate is too hard on the body to be done for long periods every day. Try to find a pace that gets your heart rate up and that is enjoyable and go for longer duration.

[@jamesgordon8867]

Heart rate goes up with lifting weights

[@oliverallen5324]

Being unfit is as bad as being diseased. Lift heavy, don't kid yourself. There's no easy way.

[@crouching-alpaca-nu9tm]

I would say there's a bit more nuance to lifting though, unless you're an athlete there's little reason to risk injury doing even 80-90% 1RM squats and deadlifts when you can just do more low weight high volume work and most likely get the exact same health benefits and closer to zero injury risk. Or even just do a bodyweight regime.

[@falsificationism]

Glad Patrick is dying on the higher-intensity hill. I think the evidence will mount over time, and in hindsight, this position will look better and better. ALL exercise is good, and varying exercises and intensities is excellent. That being said, it's VERY LIKELY true that motivated reasoning tends to guide is to things that feel 'easy' but promise outsized results. Yoga comes to mind. Again, ALL exercise, including things like yoga, is good. But there's an opportunity cost to doing nothing but lower-intensity work, and I'll bet that cost is relatively large. Happy she's proselytizing on this one!

[@TO-il3vc]

I run and lift multiple days a week and doing yoga really helps me feel "good" and relaxed afterwards. Especially in my lower back.

[@falsificationism]

@@TO-il3vc Ha! Same here. We're onto something. I do Orangetheory (sort of HIIT), a few lower-intensity zone 2 runs, Olympic weightlifting and powerlifting (I compete in both), and flexibility/yoga on recovery days. I'm definitely less injury-prone than I was in my 20s and 30s as a competitive athlete.

[@dove72]

As devil's advocate, where is there any comparison between the length of time spent performing arduous exercise versus the length of extra life gained? In other words, why is this worth the time and effort?

[@matthewcohen6339]

Exercise will improve your current quality of life, that's why it's worth the time and effort. For example just the release of endorphins from exercise will make you feel better than if you didn't do anything.

[@HSLSFirst]

This is the difference for a person later in life being able to do whatever they want whenever they want without being limited by their physical capacity’s but only by their technical skills. My wife started surfing at 58 and rock climbing at 56 motivated by my son in his 20’s

Yes. Dr Rhonda talks about "when you age..." but she's too young to really know what it feels like to have chronic joint pain/arthritis etc, or how it limits what you can do.

[@AkSeapilot]

When i started CrossFit at age 45 i couldn't do a pullup because of serious shoulder issues, i had occasional back pain and it was sometimes severe as well as knee issues (could hike up, but not down a mountain). My joints have mostly improved/healed through gaining strength in the surrounding muscles. Fast forward 11 years.. i have competed at games 2x and done a lot of things i never thought i could do.. 100 foot handstand walk in competition, 36 bar muscle ups in a competition. Ran 2 half marathons in 1 week, one at a 7:39 pace (without running to practice).. Weight 200 lbs, age 56, long term damage, possibly caused by CrossFit, my wrist hurts and i haven't found a solution. What matters most in CrossFit or similar is that you have a coach who genuinely cares about you and your injuries and knows how to prescribe the right workouts/modifications. Some might be out for profit, but most care about their members.. It is some scary shit for sure when you have a lot of aches and pains.. Given what i know 3 to 4 hours in the gym, 30% resistance training ,30 percent HIIT or some form of intense exercise, 30% stretching. Either way.. no insult to anyone who is getting into the gym at whatever level they are comfortable with.. - I would agree that some of the motions that are done to get a better time on a workout are not ideal at all. Cheers.
