High-Intensity Interval Training (HIIT) Improves Age-Related Decline in Muscle Mitochondria.
Aging can take a toll on the body all the way down to the cellular level. Older muscles do not regenerate easily and become weaker, as the energy producing mitochondria decrease in stamina and number. Even so, according to the Journal of Cell Metabolism, there are certain workouts that can reverse the damage of aging. Cell Metabolism
Researchers at the Mayo Clinic in Rochester, Minn., conducted a 12-week study on 72 sedentary, but healthy men and women in various age groups. Participants were randomly assigned a particular exercise routine several times per week and a control group that did not exercise.
Results of the study found that among the younger subjects (30 yrs. and younger) who went through interval training, the activity levels had changed in 274 genes, compared with 170 genes for those who exercised more moderately and 74 for the weight lifters. Among the older participants (64 yrs. plus) engaged in HIIT, almost 400 genes were working differently now, compared with 33 for the weight lifters and only 19 for the moderate exercisers.
The older subjects involved in HIIT showed a noticeable increase in the health and number of their mitochondria; thus, the decline in the cellular health of muscles can be improved with HIIT exercise. No matter how old you are, it’s time to start an exercise routine. A perfect class to start your journey is Yoga+Hot Pilates @ Yoga Kula Project.
