There is no difference between continuous and accumulated patterns of exercise in terms of effects on fitness , blood pressure , lipids , insulin and glucose .
There is some evidence from a small number of studies that changes in body mass and LDL cholesterol are more favourable following the accumulated condition .
Collectively our findings suggest that adults are likely to accrue similar health benefits from exercising in a single bout or accumulating activity from shorter bouts throughout the day .
Public health guidelines suggest that physical activity can be accumulated in multiple short bouts dispersed through the day .
A synthesis of the evidence for this approach is lacking .
Our objective was to undertake a systematic review and meta- analysis to examine if exercise interventions consisting of a single bout of exercise compared with interventions comprising the same total duration , mode , and intensity of exercise accumulated over the course of the day have different effects on health outcomes in adults .
Walking trials in postmenopausal women: effect of one vs two daily bouts on aerobic fitness.
We compared the effects of one vs two daily bouts of walking on aerobic fitness and body composition in postmenopausal women . One hundred and thirty-four subjects were r and omized into exercise groups or a control group and 130 completed the study . The subjects walked 5 d/week for 15 weeks at 65 % of their maximal aerobic power expending 300 kcal ( 1255 kJ ) in exercise in one ( Group S1 ) or two daily sessions ( Group S2 ) . VO(2max ) was measured in a direct maximal treadmill test . Body mass index ( BMI ) was calculated and the percentage of body fat ( fat% ) estimated using skinfold measurements . The net change in the VO(2max ) was 2.5 mL min/kg ( 95 % CI 1.5 , 3.5 ) ( 8.7 % ) in Group S1 and 2.5 mL min/kg ( 95 % CI 1.5 , 3.5 ) ( 8.8 % ) in Group S2 . The net change in body mass was -1.2 kg ( 95 % CI-1.9 , -0.5 ) in Group S1 and -1.1 kg ( 95 % CI -1.8 , -0.4 ) in Group S2 . The net fat% change was -2.1 % ( 95 % CI-2.7 , -1.4 ) in Group S1 and -1.7 % ( 95 % CI-2.3 , -1.0 ) in Group S2 . Exercise improved the maximal aerobic power and body composition equally when walking was performed in one or two daily bouts
