To compare the physiological and perceptual responses during fixed-power and perceptually regulated cycling, both without and with blood flow restriction (CON, BFR, CON and BFR). Twelve recreationally active men cycled for 10 min at the power corresponding to the first ventilatory threshold or, for CON and BFR the perceived exertion level reported during CON. Blood flow restriction was set at 60% of estimated arterial occlusion pressure.

Background: Exercise can improve cognition in aging, however it is unclear exercise influences cognition, and sleep may partially explain this association. The current study aimed to investigate whether objectively measured sleep mediates the effect of an acute exercise intervention on cognition in older adults.

Methods: Participants were 30 cognitively unimpaired, physically active older adults (69.

Purpose: This study examined the influence of blood-flow restriction (BFR) on the distribution of pace, physiological demands, and perceptual responses during self-paced cycling.

Methods: On separate days, 12 endurance cyclists/triathletes were instructed to produce the greatest average power output during 8-minute self-paced cycling trials with BFR (60% arterial occlusion pressure) or without restriction (CON). Power output and cardiorespiratory variables were measured continuously.

Article Synopsis
  • This study investigated the effects of blood flow restriction (BFR) during aerobic cycling intervals on training loads and load ratios in 14 endurance athletes.
  • Results showed that the Lucia TRIMP (a measure of internal load) was lower in BFR sessions, and total work done was significantly reduced compared to non-BFR sessions.
  • The study concluded that both internal and external training loads should be tracked when using BFR, with the Lucia TRIMP:TWD ratio being more indicative of BFR effects compared to other ratios.

This study examined cardiovascular, perceptual and neuromuscular fatigue characteristics during and after cycling intervals with and without blood flow restriction (BFR). Fourteen endurance cyclists/triathletes completed four 4-minute self-paced aerobic cycling intervals at the highest sustainable intensity, with and without intermittent BFR (60% of arterial occlusion pressure). Rest interval durations were six, four and four minutes, respectively.

J Strength Cond Res 36(12): 3541-3550, 2022-Low-intensity aerobic training with blood flow restriction (BFR) can improve maximal oxygen uptake, delay the onset of blood lactate accumulation, and may provide marginal benefits to economy of motion in untrained individuals.

The purpose of this study was to determine the agreement in peak ball speed measured using a radar gun and motion capture system then examine the influence of angular position. Peak ball speed was recorded with the radar gun in-line with the ball trajectory (0° offset) and at 5° offsets up to 35°. Agreement between devices was calculated at 0° and for grouped offset bins (0-5°, 10-15°, 20-25°, and 30-35°).
