Randomized Controlled TrialLow-volume, high-intensity, aerobic interval exercise for sedentary adults: VO₂max, cardiac mass, and heart rate recovery.
The aim of this study was to compare the effects of low-volume, high-intensity aerobic interval training (HAIT) on maximal oxygen consumption (VO₂max), left ventricular (LV) mass, and heart rate recovery (HRR) with high-volume, moderate-intensity continuous aerobic training (CAT) in sedentary adults. ⋯ This study suggests that HAIT has potential as a time-efficient training mode to improve cardiorespiratory capacity and autonomic nervous system function in sedentary adults.

Comparative StudyThe validity of the Moxus Modular metabolic system during incremental exercise tests: impacts on detection of small changes in oxygen consumption.
We investigated the accuracy of the Moxus Modular Metabolic System (MOXUS) against the Douglas Bag Method (DBM) during high-intensity exercise, and whether the two methods agreed when detecting small changes in [Formula: see text] between two consecutive workloads ([Formula: see text]). ⋯ Although it was tested during high-intensity exercise and short sampling intervals, the MOXUS performed within the acceptable range of accuracy reported for automated analyzers. Most of the differences between equipments were due to differences in [Formula: see text]. Detecting small changes in [Formula: see text] during an incremental test with small changes in workload, however, might be beyond the equipment's accuracy.

Life-long physical activity restores metabolic and cardiovascular function in type 2 diabetes.
Short-to-moderate duration exercise training improves fitness and lowers cardiovascular risk in type 2 diabetes (T2DM). However, the impact of long-term compliance to an active lifestyle of T2DM patients on cardiovascular risk factors has never been studied but could provide information on the maximal achievable health effect of physical activity in T2DM. This study examined the impact of a life-long active lifestyle by comparing physical fitness, cardiovascular risk and vascular function between long-term physically active T2DM patients versus sedentary T2DM patients and controls. ⋯ Life-long active T2DM patients have superior fitness levels, HOMA-IR, cardiovascular risk and FMD compared to sedentary peers, whilst no differences were found when compared to controls. This study provides evidence that a life-long active lifestyle, even in T2DM, may be able to effectively normalize cardiovascular risk.
