Exercise: Fountain of Youth and Miracle Healer? Part 1

Exercise: Fountain of Youth and Miracle Healer? Part 1

A recent study has shown exercising 2.5 hours a week may slow Parkinson’s progression. 3,400 patients in N. America, the Netherlands, and Israel participated in the study.

Exercise Keeps Your Cells Young!

In fact, it could be considered a ‘fountain of youth’. Even older folks (we know who we are) can REVERSE certain aspects of “cellular” aging with high intensity, interval exercise. This type of workout is brief bursts of vigorous exercise, alternating with periods of moderate exercise. For example, going all-out on a Stationary bike for a few minutes, then easing up for a few and then starting again. It can be done with walking, swimming, or any number of activities. Interval training boosts cellular “rejuvenation” better than continuous moderate aerobic and strength training exercise. If you want to better understand where you can tweak your exercise routine, here is the study specifics described in Cell Metabolism.

Exercise Variations for Great Results

One group did high-intensity interval training three days a week. They pedaled on an exercise bike at their maximum speed for 4 minutes, before easing up for 3 minutes. They repeated the process four times. The participants also worked out more moderately -- walking on a treadmill -- twice a week. A second group performed moderate aerobic exercise -- using an exercise bike at a less-intense pace: five days a week, for 30 minutes. They also did some light strength-training four days a week. The third group performed strengthening exercises only, twice a week. After 12 weeks, the researchers found all the groups were showing positive changes -- younger and older exercisers alike.

Which is Better?

People who performed strength-training -- alone or with aerobic exercise -- increased their muscle strength. People who performed moderate aerobic exercise boosted their fitness levels and the body's ability to supply blood and oxygen to working muscles, and the improvement was greater for older adults, who generally started out with lower fitness levels than younger people. The interval-training group showed only small gains in strength, but the training improved mitochondrial function in the muscles, especially among older adults. Study authors conclude this proves interval training is “probably the best form of exercise.” If you have health problems, consult your physician before jumping into this. If your exercise is outdoors, click here to see how to do it without adding sun damage to your skin. The goal is 150 minutes a week and that’s a lot of outdoor sun exposure to “un-rejuvenate” your skin cells and collagen! Stay tuned for Part 2! Reference: HealthDay SOURCES: K.
