Anticipate Change

Adapt. Innovate. Improvise. Overcome. That’s a group of words I put together years ago about how to respond when faced with challenges. The approach works in the present. When it comes to changes in health that are associated with aging, we don’t know exactly what they will be. Therefore, we must anticipate what might happen. I’ll give you some examples to consider.

Things to Consider

What we value the most is our independence. Still, your body will change; you may see changes in strength, balance, vision, joint health, mental acuity, or fitness. That doesn’t count any new conditions or diseases.

Should you continue to drive? That would be about the last thing I’d want to give up, but glaucoma may have a say in it. And reaction time declines with age. Which abilities can you work to improve? What alternatives can you prepare for?

Having a two-story home with a basement is great. Will you always have the capacity to go up and down the stairs to do laundry or to retrieve stored items? Would moving to a ranch home with everything on one level be a better choice?

Going up and down a ladder to clean gutters could become a problem. Heck, getting the extension ladder out of the garage could be an issue. Plan for gutter covers. That’s one change I made when I could do it myself. I could still clean them, but now I don’t need to.

What about cooking? Cleaning? Snow shoveling? Lawn maintenance? Anticipate what you really want to do yourself and what you’re willing to let someone else do.

Am I Just Giving Up?

Understand this. This is not about giving up; this is making a conscious decision to adapt to new circumstances. Your body is different from what it used to be.  Doesn’t matter whether you’re 40 now, or 50 or 60 or over 70—your body doesn’t have the same capabilities, and it will differ even more in 10, 20, or 50 years. You must adapt to it, or you’re going to end up frustrated all the time. Because believe me, you’re not going to be able to do everything that you used to do in the same way.

Anticipate the changes that may occur. If you start preparing for that now while you may not need it, you’ll be ready for it if you do. The choices of what you will and will not be able to do are going to be different for every person, but we can probably all stand to simplify our lives.

Anticipate. Innovate. Improvise. Adapt. And you will overcome.

The Bottom Line

There’s a new year on the horizon, so now is a good time to think about the changes I’ve talked about. Most of us are not good at anticipating what our bodies will do, but I can virtually guarantee one thing: the less body mass you have, the easier it will be to do everything. What you can do starting now is methodically get to a normal body weight for your height, stay active, and work on your strength and stamina. I’ll continue to provide you with research-based actions you can take to age with a vengeance. Nobody ever said you have to go quietly.

Life Is Change

Do you ever think about your life in five or ten years or even longer? Doesn’t matter how old you are today, whether you’re 30 or 70. What will your life be like? Let me define it more clearly for you with this example.

After Thanksgiving, Paula began setting up the Christmas tree. As she hit a snag with the lights, she stopped and asked herself a question: will I be able to do this in five or ten years? Not just putting ornaments on the tree, but all the other tasks associated with it. We talked and she decided the answer was no; it just wasn’t worth the tears and frustration. I heartily agreed—I can’t stand it when she cries. We bought a smaller tree that’s easier to set up, sold the old one to a younger family who wanted one that large, and moved on.

That’s what I’m talking about. It doesn’t matter your age or your health today. Your body is going to change as you get older. What are you going to be willing to change? What are you determined to fight for? It’s not a question of giving up; it’s a question of planning. We’re trying to be smart about choosing our battles.

We’re still going to have a large-ish tree with amazing decorations. Ten years from now, we may downsize again, but in the meantime we have a tree we can manage.

Then there are the things we’ll fight for. Two torn biceps and a fall on the ice last winter has made picking things up over my head challenging. I found that out when Riley asked me to pick him up like I used to even as little as a year ago. Training will only get me so far; the joints and tendons still have the damage of seven decades, but I’ll keep working to build back strength. Paula is working in physical therapy toward another new knee in January, because she has things to do and places to go.

I’ll continue this train of thought in the Saturday Memo with some potential solutions.

The Key to Building Muscle

The mega meta-analysis I talked about on Tuesday found that every combination of resistance, sets, reps, and number of days per week resulted in increased strength and increased muscle size compared to people who did nothing, but there were some combinations that provided the best results.

Finding the Best Approach to Building Muscle

Without question, lifting multiple sets with heavy weights improved strength the most. Even just one day per week showed an improvement in strength, but the most consistent results were found with at least two weight training sessions per week. What was surprising was that two sessions per week of multiple sets with light weights also saw a significant improvement in strength.

When it came to muscle hypertrophy, or more simply put, muscle size, lifting light weights for multiple sets twice per week saw the same improvement as lifting heavy weights multiple sets twice per week. That seems a little odd but may be supported by another recently published study.

In a pilot study with 22 subjects, half the group was put on a low-resistance, high-repetition weight training program while the other half was put on a more traditional heavy weight training program with fewer repetitions. The low-weight, high-repetition group performed sets of 20 to 24 repetitions, while the heavy-resistance group did the more traditional eight to 12 repetitions per set. The results showed similar benefits. There was an increase in muscle strength and muscle size in both approaches. Also the mean age of the subjects was 59 years. That eliminates the “younger people are stronger to begin with” factor.

Volitional Exertion
The pilot study reveals the key: in both approaches, the subjects were trained to push themselves to voluntary or what’s termed in the business as “volitional exertion.” It doesn’t mean barely able to lift the weight without assistance—it means that it would be a challenge to do one more repetition. It wasn’t the weight; it was the effort.

The Bottom Line

Since I talked about the 3/7 weight training program in the last Super Bowl webinar, I’ve favored that approach the most in my recommendations. It would be the low-resistance, high-repetition, two days per week approach. It seems better for beginners because even a two-pound resistance will produce results as long as they go to volitional exertion.

The author of the Washington Post article got it wrong when she said it would be easy to add muscle; it still requires consistency and effort. But it’s easier because it can be done in the comfort of your own home. Now, if we can just get everyone to do that—but that’s a challenge for another day.

Protein Intake: Perspective Required

The research paper that concluded that higher protein intake was associated with muscle loss and sarcopenia seems to offer more questions than answers. That’s actually a good thing, because future research can examine those questions. But there are questions that the researchers didn’t mention.

Researcher Observations

This is an observational study. Simply put, the subjects who completed all the tests were followed for several years, depending on when they joined the study. Therefore, no cause and effect can be inferred because the researchers were watching, not intervening.

The original number of subjects with sarcopenia was low at just 4.3%. With so many subjects over 72, the number should have been closer to 10%. The researchers acknowledged as much. If the study’s subjects had less sarcopenia than the general population, it’s hard to draw conclusions that are helpful to everyone.

My Observations

The single characteristic most closely associated with loss of muscle mass and sarcopenia was age. Protein intake was a covariate for sarcopenia but it was actually in the middle of the pack as a risk; a covariate is a separate attribute that can be measured alongside the primary variable being investigated.

The study included limited data on diet and exercise. I would expect that not very many subjects were exercising at levels high enough to sustain or increase muscle mass. That conflicts with the research data from clinical trials that show that increasing protein intake in older subjects on a weight training program increases strength and muscle mass.

What stood out more than anything was the limited amount of testing for sarcopenia and the mixed bag of testing procedures. If it’s such a problem, which every researcher in aging admits is the case, why aren’t there better diagnostic tools available to diagnose the condition? How can physicians treat a disease they aren’t diagnosing?

The Bottom Line

There is no reason to worry about protein intake as we get older based on this observational study. What we need to do is begin to retain muscle mass or reclaim our muscle through resistance training, better protein intake, and the strategic use of supplements. If you’re interested in a program to do just that, the Taking Back Your Muscle is still available on my website.

Is High Protein Intake Associated with Sarcopenia?

If there’s one thing I’ve learned studying health, fitness, and nutrition for 35 years, it’s this: what we thought we knew yesterday may change based on what we learn today. Given that, I was still surprised to see an article in my news feed with a title “High Protein Intake Associated With Sarcopenia.” The Taking Back Your Muscle webinar uses strategies that research has shown help increase muscle strength, including eating more protein. What gives with this latest research?

Researchers selected as their subjects from the TwinsUK cohort. Subjects must be over 60 years old and have completed specific tests since 2010. Just over 3,300 men and women were selected to be included in the data analysis. Researchers examined a variety of variables including education, income, other diseases and conditions, strength, and muscle mass. Protein intake was measured. Researchers did find the opposite of what they expected: higher protein intake was associated with sarcopenia.

Did I get it wrong? I’ll talk about the rest of the study on Saturday. I wouldn’t change your protein intake just yet because there seems to be a larger problem that looms over us as we age. The article is open access, and you can read it at this link.

Aging Stressor: The Muscular System

Sarcopenia is the number one issue that impacts muscles—that’s the loss of skeletal muscle mass and strength that comes with age. It can begin as early as the 20s in some and accelerates once we pass 60; it’s thought to be primarily due to the genetics of aging. There’s also little question that a sedentary lifestyle contributes to muscle loss. Losing muscle mass impacts not just strength, but also stamina, posture, balance, and the ability to move your body.

There are several types of muscle fibers, but they all appear to become slow-twitch fibers as we age. And they get smaller. However, and this is important, they don’t ever seem to go away completely. Strength training has been shown to be effective even for people who are 100 years old; they get stronger, which helps deal with all those issues I mentioned before. The research hasn’t demonstrated that muscles will get larger, but most studies end at three to six months, which is too soon to really judge results; it’s probably going to take more than six months to gain back what we lost over many decades.

The key to dealing with sarcopenia is strength training—the earlier in life the better, but it’s never too late. Strength training can encompass many approaches from doing squats by standing up from sitting in a chair (using a walker if balance is an issue), push-ups and other calisthenics, and weight training using bands, tubes, machines, and free weights.

There are hundreds of programs and thousands of exercises to help build strength using every modality. I think it should all begin with an evaluation by a healthcare professional to test posture and balance, as well as strength. The next step is to see a physical therapist who can evaluate your limitations and put together a plan to get you started safely; it’s hard to keep your positive attitude if you get hurt right away and need to pause. Once you get approval and a plan to train, then getting muscles prepared is important. Calisthenics, which include chair exercises for those with arthritis, are a good place to begin.

Final memo before Christmas on Tuesday with one more place to attack when we’re aging with a vengeance.

Wait a Minute!

It was a beautiful day in Grand Rapids on Thursday: 65 degrees, hazy sunshine, no wind, and a perfect day to take a kid to the park. Riley likes basketball (as is required of all children in the Midwest); he can’t hit the rim with the net at 10 feet, but that didn’t stop him and three other kids his size. Attempts were many, but baskets were few, and they didn’t seem to care.

Naturally I had to give it a try. I tried from 10 feet to the right of the basket, but my shot fell two feet short. Whoa! Tried again, and watched the ball sail under the basket. So in spite of having a three-month old knee, I tried a jumpshot—and stumbled a little as I landed. Yikes. My balance, spatial awareness, equilibrium, and power all seem to have left me in the past few months.

I sat down on a bench and pondered, “How do I get back from this far down?” I never expected things to get this bad so quickly; or has it really been even longer? I haven’t attempted anything like a jumpshot in a while. Then a phrase Riley likes to say popped into my head: “Wait a minute!” I already know the answers: Eat less. Eat better. Move more.

Moving more may mean going back to working on balance movements; spatial awareness may mean standing tall, closing my eyes, and touching my nose with my index finger. Neural pathways have to be awakened. They’re still there, just dormant.

There may be no NBA in my future, but I’ll get back to hitting that 15-foot baseline jumper this summer. Lucky for me, I have a built in practice buddy who’s always ready to play. Grandkids are the best!

Preventing Muscle Loss

This final installment on muscle focuses on keeping the muscle mass you’ve got. That’s one of the keys to living every day you’re alive: the ability to move at every age. There are three things that are important to hanging onto muscle.

  • Use it or lose it. Actually, you’re going to lose it not matter what, but the degree to which you will is partially dependent on using it. Whenever you can take the stairs, take them. Whenever you can lift something, lift it. While I would hate it personally, it was better when we had to get up and actually walk to the television to change the channel. More today than ever, we don’t take the opportunity to build muscle or increase stamina.
  • Exercise regularly. No matter your age, there’s always something you can do. Orthopedic issues happen as we get older—arthritis in hands, shoulders, hips, and knees, or torn ligaments and cartilages. They can all put limitations on what we can do. We have to work within those restrictions and do as much as we can to maintain and even increase what we have. A session with an excellent physical therapist (ask your doctor if you qualify for some free sessions) or certified personal trainer could be worth the money. It’s never too late to begin. Research has shown that even people over 100 years old can increase strength and stamina.
  • Consider taking essential amino acids every day. While the focus has been on what EAAs can do for people who train hard, the bulk of the research has been done on people 50 and older. It’s clear you can slow down muscle loss and increase muscle strength by exercising regularly and taking EAAs every day. I’ve been taking them the days I lift, but I’m considering taking them every day. In continuing to research the benefits, there doesn’t seem to be a downside to taking EAAs. There’s some preliminary research that indicates that taking EAAs may even be beneficial for pre-diabetics to reduce insulin levels and triglycerides if they exercise regularly as well.

The purpose for the month’s Memos is showing you how to learn to live every day you’re alive. Muscle is critical to that goal. We’ll move on to another important physical component of living next week.

Skeletal Muscle: Strength

This week, we’re turning our attention to skeletal muscle. Skeletal muscle allows us to move and to lift ourselves and other objects. The two primary features are strength and stamina. Let’s begin with strength.

A simple definition of strength is the most weight you could lift once. That could be as little as a couple of pounds, or it could be as much a thousand pounds as some weight lifters have done. To me, as a minimum, strength is the ability to be able to do everyday tasks. We’ll start with the most fundamental, which would be sitting down in a chair or on a commode and then having enough leg strength to stand up. It would be enough to be able to lift a bag of groceries. To lift a hammer to hit a nail. To hold a hair dryer over your head while you do your hair. You can probably think of a few more.

Years ago, I mentioned to my mother-in-law that most women over 65 can’t lift 10 pounds. We lose strength as we age. She had just gotten back from grocery shopping and she picked up a 10-pound sack of flour. She began lifting it up over her head and back down to her lap and said, “Look Chet, I can do that!” She was in her mid-seventies at the time.

Strength can vary by body joints. With two torn biceps, I don’t have nearly the strength in my arms and shoulders as I used to, but I still have pretty good leg strength and pretty good back strength; my exercise routine includes strength training for all those areas.

How do you increase strength? Challenge the muscles to lift more weight than you currently can for any different set of muscles: your shoulders, your arms, your quads, your calves, and of course, there’s your core. I’ll save that for later in the month. Next time, we’ll take a look at muscular stamina.

Move Up to Interval Training

Recently I watched an interview with the cast and production staff of the third John Wick movie, which will be released soon. What struck me was the physical preparation to do the action and fight scenes. When the third installment of the movie was announced, Keanu Reeves shouted to himself. “All right. It’s time for John Wick Training!” He worked more than six months for six to eight hours per day on physical training specific to the fights and action scenes that were going to be in the movie, and he uses stunt doubles very rarely—it’s all up on the screen. Halle Berry, who’s new to the series, jumped at the chance to do that training as well. I can’t wait.

You and I don’t have the hours in the day to do that type of training, but we can do better than we are right now. Interval training seems to have become a mainstay of fitness recommendations. I’ve used it for years to increase my fitness level. It’s stressful because the effort is so hard, but you can adjust the effort to where you are today.

Check out the Health Info titled Interval Training. It explains the concept and how to construct your own interval program. If you want to take it one step up in intensity, check out the Spartan Workout that combines strength with endurance interval training.
