TUESDAY, Dec. 12, 2023 (HealthDay News) — Replacing sitting with even a little moderate exercise each day improves heart health, according to a study published online Nov. 10 in the\u00a0European Heart Journal<\/em>.<\/p>\n Joanna M. Blodgett, Ph.D., from\u00a0University College London, and colleagues investigated associations of five-part movement compositions with adiposity and cardiometabolic biomarkers. The analysis included data from six studies (15,253 participants; five countries) as part of the Prospective Physical Activity, Sitting and Sleep consortium.<\/p>\n The researchers found that a greater moderate-to-vigorous physical activity (MVPA) proportion and smaller\u00a0sedentary behavior (SB)\u00a0proportion were associated with better outcomes. For all outcomes, reallocating time from SB, standing, light-intensity physical activity (LIPA), or sleep into MVPA resulted in better scores. Replacing 30\u00e2\u0080\u0085minutes of SB, sleep, standing, or LIPA with MVPA was associated with \u00e2\u0088\u00920.63, \u00e2\u0088\u00920.43, \u00e2\u0088\u00920.40, and \u00e2\u0088\u00920.15 kg\/m2<\/sup> lower body mass index, respectively. There was a benefit to greater relative standing time. But sleep had a detrimental association when replacing LIPA\/MVPA and positive association when replacing SB. For improved cardiometabolic health, the minimal displacement of any behavior into MVPA ranged from 3.8 (hemoglobin A1c) to 12.7 (triglycerides) minutes\/day.<\/p>\n “The most beneficial change we observed was replacing sitting with moderate to vigorous activity — which could be a run, a brisk walk, or stair climbing — basically any activity that raises your heart rate and makes you breathe faster, even for a minute or two,” Blodgett said in a statement.<\/p>\n
