Baby, it’s cold outside, but even if you’re willing to bundle up and go for a run or sprint to the gym to work out, should you?
I have a meaningful exercise routine, and I have never felt better. I am still glowing from that moment a few months ago when, at the age of 59, I crossed the finish, for the first time, at the Marine Corps Marathon.
At a certain point, when you get to a certain age — say, 60, which I’ll be this month — it is not just about your willingness to exercise.
It is about your readiness for exercise.
Aging athletes know we need more time to recover from our workouts, but how can we tell if we have recovered enough? Or whether we are not pushing hard enough for our exercise to matter? When we were younger all we had to do was lace up our shoes and go.
“Whether you’re a competitive athlete or a recreational one, either finding an intuitive understanding of your readiness to exercise or using some external measures can improve your overall fitness and help you avoid injury,” according to sports medicine specialist and physical therapist Kevin McGuinness, who practices at Washington Orthopaedics & Sports Medicine. Exercising, particularly as you age, might also require a more scientific approach to how you are feeling and how you are doing, he said.
The good news is there is some promising research on exercise readiness, according to Carwyn Sharp, chief science officer at the National Strength and Conditioning Association in Colorado Springs. Although there are no specific guidelines yet for recreational athletes, what experts have learned so far can help us enhance our intuitive sense of readiness by throwing some objective measures into the mix.
One way is to monitor your resting heart rate, which can help you understand how well you are recovering from your previous exercise session. If you keep a log of your resting heart rate, you will get a sense of what is normal for you. If it is higher than usual, McGuinness said, that is often a sign your nervous system may be overstressed, indicating a lower level of recovery.
“There is research that shows that changes in your resting heart rate over time can be a measure of total stress level in the body,” Sharp said. “And what you want to focus on is trends.” For example, over time with aerobic training we should expect our resting heart rate to decrease, which is a sign of improved cardiovascular fitness, Sharp said. So if your resting heart rate is going up over time, that can be a sign your body is experiencing too much chronic stress and needs more rest.
