Short brisk walking bouts lack cardiac benefit in middle-aged adults; challenges minimal-dose assumptions and extends RCT evidence for alternative regimens.
Does 18 weeks of accumulative short bouts of brisk walking improve cardiac function in healthy men and women aged 40-68 years who are not habitual exercisers?
Accumulative short bouts of brisk walking over 18 weeks do not appear to improve cardiac function in healthy, non-exercising middle-aged adults.
