Venous hemodynamics during blood flow restriction exercise: Impact of cuff type and arm position.

Purpose: Blood flow restriction (BFR) training is an exercise training modality to accelerate fatigue in exercising limbs by restricting blood flow. Although arterial inflow has been studied, its impact on venous hemodynamics remains unclear. This study examined the effects of cuff type and arm position on venous hemodynamics during BFR exercise.

Vascular adaptations to blood flow restriction resistance training with different cuff types: the role of retrograde shear stress.

Purpose: Narrow-elastic bands (NE) and wide-rigid cuffs (WR) are two types of cuffs that are frequently used in blood flow restriction (BFR) training. Because these cuffs produce different hemodynamic responses, vascular adaptations might differ depending upon what cuffs are used. We examined the hypothesis that BFR with NE would improve vascular function while BFR with WR would decrease vascular function.

A new and specific automated blood pressure device for exercise stress testing.

Blood pressure (BP) measurement plays a critical role in cardiac stress testing and is most commonly assessed manually. The emphasis of social distancing during the COVID-19 pandemic has renewed the interest in and the need for an automated BP device for incremental exercise stress testing. We assessed the accuracy of a new automated blood pressure device specifically manufactured for cardiac stress testing.

Effects of supra high-intensity interval training in police officers.

Background: The job environment of a police officer involves unusually high physical and mental stressors paired with hours of prolonged sedentary behavior. The availability of police officers to engage in traditional regularly-scheduled exercises is generally restricted by irregular shift hours. Therefore, supra high-intensity interval training (supra HIIT) may be a viable training option as it elicits physical and mental health benefits and a training session can be completed in less than five minutes.
