Chronic diseases tend to depend on a large number of risk factors, both environmental and genetic. Average attributable fractions were introduced by Eide Gefeller as way partitioning overall disease burden into contributions from individual factors; this may be useful in deciding which factors target interventions. Here, we introduce new estimation methods for average that are appropriate case–control designs prospective studies. Confidence intervals, derived using Monte Carlo simulation,...

When oxygen delivery to active muscle is insufficient meet the metabolic demand during exercise, metabolites accumulate and stimulate skeletal afferents, inducing a reflex increase in blood pressure, termed metaboreflex. In healthy individuals, metaboreflex activation (MMA) submaximal exercise increases arterial pressure primarily via an cardiac output (CO), as little peripheral vasoconstriction occurs. This CO partially restores flow ischemic muscle. However, we recently demonstrated that...

Blood flow restriction training (BFRT) increases muscle mass, strength, and endurance. There has been minimal consideration of the reflex cardiovascular responses that could be elicited during BFRT sessions. We showed low-intensity exercise may trigger large in blood pressure sympathetic activity due to metaboreflex activation. Thus, we urge caution when employing BFRT, especially patients whom exaggerated occur cause sudden, adverse events.
