Deans' stroke musings: Do Short Spurts of Physical Activity Benefit Cardiovascular Health? The CARDIA Study

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Do Short Spurts of Physical Activity Benefit Cardiovascular Health? The CARDIA Study

There really is almost nothing that I can do for short bursts because my doctors and therapists completely failed at getting me recovered. I can't run, bike or swim.

Abstract

Background

For optimal health benefits moderate to vigorous intensity physical activity (MVPA) is recommended in sustained bouts lasting ≥ 10 minutes. However, short spurts of MVPA lasting < 10 minutes are more common in everyday life. It is unclear whether short spurts of MVPA further protect against the development of hypertension and obesity in middle-aged adults beyond bouted MVPA.

Methods

Objectively measured physical activity was collected in the Coronary Artery Risk Development in Young Adults (CARDIA) study at the 20-year (2005–2006) examination, and blood pressure and BMI were collected at the 20-year and 25-year (2010–2011) examinations. Time spent in MVPA was classified as either bouted MVPA, i.e., ≥ 10 continuous minutes or short spurts of MVPA, i.e., < 10 continuous minutes. To examine the association of short spurts of MVPA with incident hypertension and obesity over five years, we calculated risk ratios (RR) adjusted for bouted MVPA and potential confounders.

Results

Among 1,531 and 1,251 participants without hypertension and obesity, respectively at Year 20 (Age 45.2 ±3.6, 57.3% Women, BMI 29.0 ± 7.0), 14.8% and 12.1% developed hypertension and obesity by Year 25. Study participants in the highest tertile of short spurts of MVPA were 31% less likely to develop hypertension 5 years later (RR=0.69 [0.49, 0.96]) compared with those in the lowest tertile. There was no statistically significant association of short spurts of MVPA with incident obesity.

Conclusion

These findings support the notion that accumulating short spurts of MVPA protects against the development of hypertension, but not obesity in middle-aged adults.
