Eating for Muscle Strength
Spinach anyone? Popeye wasn’t wrong! Diet is important too, and studies show that Vitamin C and magnesium play a significant role in muscle health. A study by scientists of 5,700 older people by University College London showed that those who stick most closely to a Mediterranean diet are less than half as likely to become frail over a 4 year period than those who followed it less closely. I’ve mentioned this before in relation to weight control and longer- life studies, but it really does seem that a diet consisting of lots of fruit, leafy green vegetables and olive oil with moderate amounts of fish, poultry and dairy, and with low intake of red meat and added sugar is the way to go. Vitamin C is found in citrus fruits, but is also present in coloured vegetables like carrots and peppers (and spinach) as well as bananas, apples and pears. Plant foods are also a good source of magnesium, as is fish.
Activities for Muscle Strength
The more everyday physical activity you do, the stronger your muscles will be. Gardening is brilliant because you’ll be using your whole body through a range of movements, but so is brisk walking, carrying heavy shopping bags and energetic housework. However, as I am an occasional gardener in my tiny plot in Wimbledon, loathe housework and only shop a couple of times a week since Covid struck, I know that I need to make a concerted effort to stave off the inevitable sarcopenia. So, I have equipped myself with 3 sets of weights of 1, 2 and 3 kg and I now use them to do a series of exercises which are designed to maintain and (hopefully) gradually increase my muscle strength. Apart from the weights (each set was about £14 and I bought them online), my muscle strengthening routines require no other equipment and very little room. Here’s what I have found works for me:
1. Squats
This is where you go from standing and then bend your knees as if you are going to sit down in a chair, and then push yourself back up to a standing position. Make sure that your knees are not over your feet, but back slightly so that your leg muscles are working to maintain your position. A daily routine starting with just 60 seconds of squats will significantly boost strength. Why? Because squats engage the most powerful muscle groups in your legs and buttocks and also recruit multiple joints including the hips, knees and ankles. Start with 60 seconds of squats daily and add more as you feel you can. Fast and furious isn’t necessary - a slower squat still loads the same muscles and joints. In addition all movements that lift your own body weight is a form of resistance training. So, lunges, push ups, bear crawls and planks could be added to your squatting routine to bolster strength.
2. Weights.
Many of you will know that I spent the first 69 years of my life as a virtual couch potato, so when I use my weights I feel ridiculously sporty (and yes, I know how daft that sounds!). At one, two and three kilos my weights are not impressively heavy but they don’t need to be. I’m not aiming for bulging biceps, but creating muscle fatigue, so it doesn’t matter if that happens lifting lighter weights more often. Holding one weight in two hands or one in each I can create a workout designed to strengthen muscle groups in my upper body, including my arms, shoulders, back, chest, waist and stomach. I reckon that my manic pedalling on my exercise bike really helps to strengthen my calf and thigh muscles, so most weeks I am maintaining and hopefully enhancing my overall physical health and preventing the dreaded sarcopenia.
3. Grip Strength.
How can you measure how strong you are? Quite simply by using a dynamometer to do a grip strength test which is highly predictive of functional limitations and frailty in later life. In October 2017 I had one of those head to toe health check-ups. I was approaching 70 and felt that a physical once-over might be helpful. It showed that I was slightly overweight, had slightly raised cholesterol but was generally very healthy. My grip strength was ‘good’ at 31.4kg, which put me on a par with a female of 55-59 with a strong grip. Three years later I have considerably upped my level of aerobic activity with my exercise bike and I’ve also worked with Lindsay, a personal trainer in twice weekly sessions. I was interested to see if any of that had made me stronger, so this week I bought a Dynamometer for £12.99 online and did the test this morning. Gratifyingly, despite being three years older, my grip strength is now 34.8 kg putting me on a par with a female of 35-39 with a strong grip strength and way above the average for my age which is in the range of 14.7 (weak) 14.7 - 24.5 (normal) or more than 24.5kg (strong).
