It’s normally acknowledged that most cardio capability (VO2Max) declines with age at a charge of about 10% per decade in sedentary folks, however that those that proceed to do health coaching will solely lose this capability at about 5% per decade. A typical examine upon which this rule of thumb is predicated is ref. 1. This is without doubt one of the causes for the maxim “use it or lose it”. It seems to be “actually use it so that you lose it extra slowly”. But it surely’s vital as a result of the distinction between 5% and 10% is large for high quality of life. Actions of each day dwelling like with the ability to go up stairs grow to be very troublesome or inconceivable if VO2Max goes beneath about 20. This may occur by the point you’re about 70 or 80 if sedentary, however will be delayed till greater than 100 years of age when you preserve coaching.
One other vital issue is that it has been proven that cardio capability will be regained considerably over just a few months of coaching in older individuals who have beforehand been sedentary (Ref 2). So when you get to a sure age, and notice you’re slowing down (“Why am I beginning to get winded strolling over to the mailbox?”), you may readily flip the clock again just a few many years, fitness-wise, by getting severe about coaching to get in form.
However a 2022 meta-analysis [2] seemed on the knowledge from numerous earlier research to reexamine this matter. I realized of this from Alex Hutchinson’s “Sweat Science” in Exterior Journal (there could also be a pay wall on the hyperlink however they normally permit you just a few free peeks at articles). A very powerful discovering is that even severe athletes who proceed coaching, have a tendency to cut back their coaching quantity (variety of hours per week) over time. Amongst those that sustain their quantity, the speed of loss in VO2Max is even smaller, extra like 2.5% per decade. Alex identified that coach Alan Couzens, based mostly on knowledge from his personal athletes, goes additional to recommend {that a} decline in health could also be prevented totally if we enhance our coaching quantity as we age. Coach Couzens got here up with the rule of thumb that we’ve got to coach our age, in hours, every month, to realize this. So if you find yourself 80 you simply have to coach 80 hours monthly, or 20 hours per week. This can be a lot, clearly, and properly past the 150 minutes (2 1/2 hours) per week of coaching usually advisable by well being authorities.
However this will likely truly be possible for a few of us who’re retired and for whom health is our interest. By coincidence, I presently do practice for about 2 1/2 hours per day on common, as a result of I take pleasure in it, which precisely meets Couzens’ rule. If I simply bump it up a bit every year, and by the point I’m 80 I do about 3 hours per day, does that imply I’ll lose no health in any respect? I’ll be excited to seek out out 10 years from now.
All of this has oversimplified the difficulty by solely contemplating coaching quantity and never depth. Varied strategies exist for enhancing VO2MAX considerably with decrease quantity and better depth coaching. In all probability probably the most well-known is the Tabata protocol, which takes solely 4 minutes complete however includes 8 rounds of 20 seconds of sprinting with solely 10 seconds of restoration in between. Time-efficient, however very robust! I might speculate that those that practice with significantly much less quantity, however preserve their depth excessive sufficient, may additionally combat off the decline in health with age fairly properly. I’ve additionally seen the alternative impact. There are cyclists within the membership I experience with which have stored their coaching quantity fairly excessive for many years, however their depth has decreased over time (they’ve both gotten slower or are doing fewer climbs). So I think protecting quantity excessive and persevering with to do some high-intensity work are each vital to stop getting slower.
What about for these of us for which health is not a interest and usually are not notably excited on the prospect of coaching for hours per day? I might say simply attempt to get the general public well being suggestion of two 1/2 hours per week of exercise. And throw in some higher-intensity stuff like strolling up stairs or biking up hills not less than as soon as per week (different features of health like resistance coaching and steadiness coaching are additionally vital). Your health could decline some over time, however lots lower than for a sedentary individual, and also you’ll nonetheless be capable of do actions of each day dwelling at 100. Not a foul consequence.
