The present study aims to examine the effect of 4 h of continuous sitting on cerebral endothelial function, which is a crucial component of cerebral blood flow regulation. We hypothesized that 4 h of sitting may impair cerebral endothelial function similarly to how it affects lower limb vasculature. Thirteen young, healthy participants were instructed to remain seated for 4 h without moving their lower limbs.

Low-intensity resistance exercise with slow movement and tonic force generation (LRST) effectively improves cognitive inhibitory control (IC) while heightening the subjective perception, which is a barrier to exercise adherence. Compared with concentric (CON) contractions, eccentric (ECC) contractions have greater brain activation related to cognitive functions while decreasing subjective perception. Therefore, we examined whether LRST with a longer duration of ECC contraction (ECC-LRST) could further enhance exercise-induced IC improvement while reducing the subjective perception, compared with traditional LRST.

Article Synopsis
  • Aerobic exercise improves cognitive functions like executive function (EF) and memory recognition (MR) and boosts brain-derived neurotrophic factor (BDNF) levels.
  • In this study, 22 young men took either essential amino acid (EAA) supplements or a placebo before doing moderate-intensity cycling.
  • Results showed that EAA supplementation led to improved EF post-exercise, but did not significantly affect MR or BDNF levels.

Article Synopsis
  • The study aimed to assess how blood lactate levels change after two bouts of exercise, focusing on moderate-intensity aerobic exercise (MIAE) and resistance exercise (RE).
  • It was hypothesized that blood lactate would be lower after the second bout of MIAE, and that performing MIAE before RE (concurrent exercise) would reduce lactate buildup during resistance exercise.
  • Results showed that while blood lactate was indeed lower after the second MIAE session, the type of exercise order (MIAE before RE vs. RE before MIAE) did not significantly alter lactate levels during either exercise type.

Article Synopsis
  • Decision-making speed and accuracy are crucial in sports, with prolonged cognitive load (pCL) worsening reaction time (RT) at rest.
  • Exercise enhances RT and executive function (EF), but when combined with pCL, it can impair both.
  • A study with male participants showed that pCL slowed reaction times more than rest or exercise alone, indicating cognitive load negatively impacts performance even during physical activity.

The length of rest interval between sets (i.e., inter-set rest interval) is an important variable for resistance exercise program.

Resistance exercise (RE) with blood flow restriction (BFR) is recognized as a beneficial strategy in increasing skeletal muscle mass and strength. However, the effects of BFR on changes in perceptual parameters, particularly those related to exercise adherence, induced by RE are not completely understood. In this study, we examined the exercise adherence-related perceptual responses to low-load BFR-RE.

This study compared the effects of low-intensity resistance exercise with slow movement and tonic force generation (ST-LRE) and high-intensity resistance exercise (HRE) on post-exercise improvements in cognitive inhibitory control (IC). Sixteen young males completed ST-LRE and HRE sessions in a crossover design. Bilateral knee extensor ST-LRE and HRE (8 repetitions/set, 6 sets) were performed with 50% of one-repetition maximum with slow contractile speed and 80% of one-repetition maximum with normal contractile speed, respectively.

Background: The extremely low loads (e.g., <30% of one-repetition maximum) involved in performing resistance exercise are effective in preventing musculoskeletal injury and enhancing exercise adherence in various populations, especially older individuals and patients with chronic diseases.

Background: Blood flow restriction (BFR) exercise is recognized as a beneficial strategy in increasing skeletal muscle mass and strength. These positive effects can also be obtained by a mild exercise mode such as walking. However, BFR exacerbates some perceptual responses, such as perceived exertion response, induced by exercise.

We previously determined that improvement in cognitive inhibitory control (IC) immediately after localized resistance exercise was greater for high-intensity resistance exercise (HRE) than for low-intensity resistance exercise (LRE). However, our previous study used the same total repetitions (i.e.

We previously demonstrated that duration of aerobic exercise plays an important role in improving cognitive inhibitory control (IC). Repeated bouts of aerobic exercise (R-EX), which are performed with a rest interval, is a useful strategy in improving physical health parameters in similar manners to a single bout of aerobic exercise (S-EX). However, whether R-EX would be effective in improving IC remains unknown.

Purpose: Blood flow restriction (BFR) walking is recognized as a beneficial strategy for increasing skeletal muscle mass and strength. No study has examined the effect of BFR exercise on cognitive functions, including executive function (EF). In this study, we examined the effect of BFR walking on EF.
