Endurance training involves manipulation of intensity, duration, and frequency of training sessions. The relative impact of short, high-intensity training versus longer, slower distance training has been studied and debated for decades among athletes, coaches, and scientists. Currently, the popularity pendulum has swung towards high-intensity interval training. Many fitness experts, as well as ...

CONTEXT A higher duration and intensity of exercise may improve long-term weight loss. OBJECTIVE To compare the effects of different durations and intensities of exercise on 12-month weight loss and cardiorespiratory fitness. DESIGN, SETTING, AND PARTICIPANTS Randomized trial conducted from January 2000 through December 2001 involving 201 sedentary women (mean [SD] age, 37.0 [5.7] years; me...

BACKGROUND Limited data exist directly comparing the relative benefits of moderate- and vigorous-intensity activities with all-cause and cardiovascular (CV) disease mortality rates when controlling for physical activity volume. METHODS AND RESULTS We followed 7979 men (Harvard Alumni Health Study, 1988-2008) and 38 671 women (Women's Health Study, 1992-2012), assessing their physical activity...

BACKGROUND It is generally accepted that physical training decreases blood pressure in hypertensive subjects, but the importance of training intensity has not been established. This study compared the effects of endurance training at different intensities on ambulatory blood pressure and on blood pressure load (percentage of readings above 140/90 and 120/80 mm Hg during the waking and sleeping ...

the aim of this research was to evaluate the effect of one session of exhaustive exercise with low intensity (55-65% vo2max), moderate intensity (65-75% vo2max) and high intensity (75-85% vo2max) on adiponectin in active women. for this purpose, 30 healthy women (mean age 21.6 years, weigh 59.7+3.35 kg, vo2max 39.1+0.58 ml/kg/min, no history of cardiovascular diseases and diabetes) were selecte...
