Context: Given the comparable muscle hypertrophy constantly observed between blood-flow restriction exercise (BFR-RE) and conventional resistance exercise, understanding their particular rating of perceived exertion (RPE) and pain may help to better prescribe exercise at a low-discomfort level, thus increasing its feasibility.
Design: Randomized crossover study.
Objective: To compare the RPE and pain response between conventional high- (HI-RE) and low-intensity resistance exercise (LI-RE) protocols to failure with a nonmuscular failure LI-RE associated with BFR-RE.
Participants: A total of 12 men (age: 20 [3] y; body mass: 73.5 [9] kg; height: 174 [6] cm).
Interventions: Four sets of 45° leg-press exercises in 3 different conditions: (1) BFR-RE (15 repetitions; 30% 1-repetition maximum), (2) HI-RE (80% 1-repetition maximum to muscular failure), and (3) LI-RE (30% 1-repetition maximum to muscular failure).
Main Outcome Measures: RPE and pain were assessed immediately before exercise session and after the end of each of the 4 sets.
Results: RPE and pain levels increased throughout the exercise sets for all RE protocols (all, Ps < .05). HI-RE and LI-RE protocols showed similar increase in RPE and pain levels during all exercise sets (P < .05); however, both protocols demonstrated higher RPE and pain response compared with BFR-RE after each of the 4 sets (all Ps < .05 between-group comparisons).
Conclusions: Our results demonstrated that both HI-RE and LI-RE to muscular failure resulted in similar and significant increases in RPE and pain levels, regardless of exercise intensity. In addition, nonmuscular failure BFR-RE also increased RPE and pain response, however, to a lower extent compared with either HI-RE or LI-RE.

Optimizing bike position is essential for enhancing cycling performance, improving comfort, and reducing injury risk. This study examined the acute effects of a bike fit using the idmatch system on power output, rate of perceived exertion (RPE), and discomfort in recreational cyclists. Twelve participants (10 males, 2 females; 37.

The effects of estradiol and progesterone fluctuations during the menstrual cycle (MC) on strength and fatigue remain unclear. This study investigated their impact on peak torque and fatigue in isokinetic tests. Eleven strength-trained women performed five knee extensions and flexions to assess maximum peak torque, rating of perceived exertion (RPE), and rating of perceived pain (RPP).

Introduction: Inflammatory type 1 CNVM is a severe but uncommon complication associated with posterior uveitis.
Case Presentation: We report a case of type 1 CNVM in a 50-year-old man with a documented history of viral ocular infection. Although inflammatory CNVM is frequently associated with posterior uveitis due to tuberculosis and toxoplasmosis, its occurrence secondary to viral uveitis is rare.

Blood flow restriction (BFR) training has been shown to induce exercise-induced muscle damage (EIMD) in some cases, although findings are inconsistent and the influence of the applied arterial occlusion pressure (AOP) remains unclear. This single-blind, randomized controlled trial investigated the effects of different percentages of AOP on EIMD and acute physiological responses in 40 participants allocated to four groups: no pressure (NP), low pressure (LP; 50% AOP), medium pressure (MP; 75% AOP), and high pressure (HP; 100% AOP). Participants performed unilateral knee extensions at 30% of their one-repetition maximum up to four sets of 20 repetitions or until failure.

Initial self-control exertion can impair subsequent physical performance, with perceptions of pain and motivation proposed as potential mechanisms. Examining state anxiety in this context is critical, as reductions may reflect more adaptive emotional responses to exertion in alexithymic athletes. Whilst yet to be explored, the limited emotional awareness and regulation associated with alexithymia may buffer against the performance-depleting effects of self-control exertion.
