Background: Regular physical activity (PA) is important for reducing the risk of chronic diseases and improving overall health. Activity Quotient (AQ) is a novel metric that translates heart rate during PA into a weekly score, providing an objective measure of an individual's PA. We prospectively examined the association of AQ with cancer and cardiovascular (CVD) mortality outcomes, the two major causes of death, in a Taiwanese population.

- The study aimed to find the cardiorespiratory fitness (CRF) levels necessary for older adults (70-77 years) to reduce their risk of death, hypothesizing that higher peak oxygen uptake (VO) would be protective.
- The research included a cohort of 1,565 older adults in Norway, who underwent VO testing and were monitored for all-cause mortality over five years.
- Results indicated that lower VO levels (less than 26.5 mL/kg/min for men and 22.2 mL/kg/min for women) significantly increased the risk of death, emphasizing the need for maintaining or improving CRF in later life.
Article Synopsis
- The study examined the link between Personal Activity Intelligence (PAI) scores and coronary heart disease (CHD) in a large group of healthy adults in Norway, emphasizing the impact of physical activity intensity on CHD risk.
- Researchers analyzed data from over 40,000 participants, finding that those with higher PAI scores (51-99 and ≥ 100) had a significantly lower risk of experiencing fatal and non-fatal CHD during a median follow-up of 13.1 years.
- The inclusion of PAI in traditional risk assessments improved the ability to classify individuals' CHD risk, highlighting that a PAI score above 50 is notably protective against CHD.
Comparison of exercise training modalities and change in peak oxygen consumption in heart failure with preserved ejection fraction: a secondary analysis of the OptimEx-Clin trial.

Aims: Exercise training (ET) is an effective therapy in heart failure with preserved ejection fraction (HFpEF), but the influence of different ET characteristics is unclear. We aimed to evaluate the associations between ET frequency, duration, intensity [% heart rate reserve (%HRR)] and estimated energy expenditure (EEE) with the change in peak oxygen consumption (V̇O2) over 3 months of moderate continuous training (MCT, 5×/week) or high-intensity interval training (HIIT, 3×/week) in HFpEF.
Methods And Results: ET duration and heart rate (HR) were recorded with a smartphone application.
Article Synopsis
- The study investigates the relationship between the left atrial (LA) and left ventricular (LV) volumes in healthy individuals to better understand the impact of factors like age, sex, and cardiovascular risk on heart function.
- Researchers analyzed data from 1,348 adults, discovering that higher LA to LV volume ratios are linked to an increased risk of diastolic dysfunction and that this measure can enhance the assessment of heart filling pressures.
- Ultimately, the findings suggest that the LA:LV ratio could be valuable in distinguishing between normal and pathological LA enlargement, particularly in those with enlarged LA volumes.
