Cardio ~ Does It Make You Feel Young?
As you approach middle age and beyond, you may start noticing that things don't always work the way they used to. Maybe you get tired more easily or you find it's harder to stand up after you've been sitting on the floor for a while. You may even start to feel the occasional ache or pain in well-used joints. Just because you're aging chronologically doesn't mean you need to put up with aging biologically.
When an individual ages, a natural decline in aerobic capacity begins to take place at the rate of approximately five ml/[kg*min] per decade. This basically means that if you were in great cardiovascular shape in your 20s, with an aerobic capacity of 50 ml/[kg*min], by your 60s your aerobic capacity would have dipped to 30 ml/[kg*min]. Likewise, if you were in average shape in your 20s with an aerobic capacity of 40 ml/[kg*min], by your 60s your aerobic capacity would have dipped to 20 ml/[kg*min].
If you are looking to get healthy for you, or someone else, maybe your kids or grand kids, it isn't too late to get started. Always see your doctor first, and ease into the program.
Remember, a healthy approach to living is a journey. You need support, a good plan and program, and motivation. In order to improve your aerobic capacity, you have to challenge your heart and lungs. Just like you have to lift heavier weights in order to become stronger. If the thought of pushing yourself hard throughout your workout is enough to make you forget about starting, you can take a sigh of relief—pushing yourself hard throughout your workout is unnecessary.
