Increasing energy with exercise

Increasing energy with exercise:  How does exercise increase our energy?

VO2

Improving the fitness of the heart and lungs through cardiovascular/aerobic exercise increases our VO2.  The higher our VO2 the more efficient we become at creating energy for ourselves by combining oxygen with glucose to make ATP.

Heart

Increasing fitness will increase the strength of heart. The heart can work more efficiently, expelling more blood with each beat.  More blood = more oxygen which means fewer beats required for any activity that increases the heart rate.

Strength

When we improve the strength of our muscles we do not need to max out our muscular effort.  If we could only lift 10 lbs of groceries, and now we have increased our strength to be able to lift 15 lbs of groceries, the 10 lbs will seem easy, with less effort required.  Therefore, more “energy” will be left over for other activities. 

Endurance

The same goes for endurance of a muscle.  I had a colleague that was used to treating shoulder problems. She decided to help out on the post-operative floor getting patients out of bed.  Half way through the morning, her back was sore and she needed a break.  The endurance of her back muscles was not sufficient for the task at hand.  Her back muscles were out of gas before the morning was over.  

Flexibility and range of motion

Having the flexibility and range of motion needed for a task will help conserve our energy bank.  For example, if you sit a lot, and have tight hip flexors (quad/psoas), every time you try to stand straight, there will be some relative resistance to standing straight.  This ultimately results in an increased use of our extensors(back and hips) and may make standing straight more effortful.

Endorphins

Endorphins are released during exercise and can make us feel lighter and brighter on a physical and cognitive level . Endorphins can also decrease the experience of pain. This may result in a reduced level of stress, leaving more energy for other tasks.

Summary and support!

Exercise will increase your energy levels.

Exercise resolutions 2023

Leave a comment

Not sure where to start with your exercise resolutions 2023? No pressure. I will go first:

First, my exercise evolution update

With the exception of the last 7 days, my routine has been pretty consistent and I look forward to resuming and evolving my program in the new year. In short, I will be continuing with lunchtime cycling, after work stretch and strengthening (machine, body weight and theraband, primarily legs), twice weekly Essentrics® class(teach), teaching a new mini class Wednesday am, weekly HIIT online class with my exercise peeps, and walks to and from work (get the snowpants out!)

I have some more specific goals that are exercise related:

A) I want to retest my VO2 max with a step test (Modified Canadian Aerobic Fitness Test (mCAFT)). Not sure what VO2 is? Check this post.

B) I want to retest my heartrate level during my fitness classes to see if my past calculations on time spent in a moderate intensity zone is accurate.

C) And I am strongly considering the dabble. This involves an in person or perhaps online ballet class. It will be very interesting to see how the class feels as it has probably been about 12 years since I have stepped into a dance studio. In person would be ideal as well as my biggest challenge. I will keep you posted.

Now for you.

If you don’t have any ideas, check out some of my past posts:

Q: Would you like to find out where you are on the exercise and activity spectrum? If you know where you are, you might be able to envision where you want to go.

Q: What do you want, what do you need? Check out Exercise Specificity.

Q: Do you need a story to get the ideas flowing? I’ve got a couple: The evolution of a group exerciser and Keeping it real.

I am going to open up the comments so if you wish to post your exercise resolutions or activity plans for the 2023 please do. It can be simple or with some detail.

If you don’t have any resolutions, don’t worry. The beauty of exercise and physical activity is that you can start anytime you want. Whenever you are ready. Exercise is one of those things that for many of us has its ebbs and flows. No guilt required.

And if you need help, find some help. Follow up with your favorite health practitioner or fitness professional. Complete an activity readiness questionnaire if you have any concerns. I plan to provide you with more structure and support, so feel free to join my email list for further updates very soon!

Are you ready? Then get set! Let’s GO!!
