Perceived exertion reflects fatigue conditions during power-aimed resistance training.

Fatigue is an inevitable part of resistance training, making its monitoring crucial to prevent performance decline. This study evaluated the validity of ratings of perceived exertion (RPE) as a measure of fatigue during power bench press (BP) exercises. Fourteen sub-elite male athletes completed three BP tasks with varying volumes (low, medium, high) at 65% of their one-repetition maximum.

Progression and risk factors of hallux valgus angle in elite adolescent dancers: a cohort study.

Introduction: To the best of our knowledge, no previous studies have linked the progression of hallux valgus (HV) with plantar pressure distribution. Therefore, this study aimed to determine the progression of HV angle in elite adolescent dancers and evaluate the risk factors associated with foot plantar pressure during demi-pointe movement.

Methods: For this cohort study, 40 adolescent dancesport dancers (age: 14.

Can Perceived Exertion and Velocity Loss Serve as Indirect Indicators of Muscle Fatigue During Explosive Back Squat Exercise?

Muscle fatigue is inevitable during resistance exercises, making its monitoring essential for maintaining athletic performance and reducing the risk of injury. Ratings of perceived exertion (RPE) and velocity loss have been reported as reliable indicators of muscle fatigue during explosive resistance exercises. However, their validity has been assessed only indirectly.

Validity of using perceived exertion to assess muscle fatigue during back squat exercise.

The rating of perceived exertion (RPE) scale has been found to reflect physiological responses, and this study aimed to assess the validity of using the Borg CR-10 scale and velocity loss to evaluate muscle fatigue quantified by surface electromyography during back squat (BS) exercise. A total of 15 collegiate male athletes underwent three non-explosive BS tasks comprising low, medium, and high volumes at 65% of their one-repetition maximum. RPEs, spectral fatigue index (SFI), and velocity loss during BS exercise were assessed throughout the trials.

Validity of using perceived exertion to assess muscle fatigue during resistance exercises.

Background: The rating of perceived exertion (RPE) is correlated with physiological variables. The purpose of this study was to assess the validity of using the Borg CR-10 scale and velocity to predict muscle fatigue assessed by surface electromyography during single joint resistance exercises.

Methods: Fifteen healthy males underwent different fatigue levels of unilateral elbow flexion (EF) and knee extension (KE), consisting of low, medium, and high volumes at 65% of their one-repetition maximum.

Changes in Urinary Titin N-terminal Fragment Concentration after Concentric and Eccentric Exercise.

We aimed to compare the urinary titin N-terminal fragment (UTF) concentration after concentric and eccentric exercise and to clarify the specific response of UTF to exercise-induced muscle damage (EIMD). Nine healthy young men performed 30 concentric elbow flexion exercises with maximum effort, rested for at least eight weeks, and performed eccentric exercises at the same workload using the same arm. Changes in the maximal voluntary isometric contraction (MVIC), muscle soreness (SOR), range of motion (ROM), serum creatine kinase (CK) activity, and UTF concentrations were recorded before and after for six consecutive days after exercise.

Effects of rest interval array on training volume, perceived exertion, neuromuscular fatigue, and metabolic responses during agonist-antagonist muscle alternative training.

Background: Agonist-antagonist muscle superset (SS) and paired-set (PS) strength training protocols enable the completion of training activities within a shorter period of time than traditional set. The purpose of this study was to investigate the effects of PS and SS through total volume (TV), set volume (SV), blood lactate concentration (LAC), rating of perceived exertion (RPE), and neuromuscular fatigue index (FInsm5).

Methods: Eleven males who train recreationally performed PS and SS consisting of bent-over row (BOR) and bench press (BP).
