L-citrulline (CIT) supplementation seems to improve resistance training performance; yet, whether malate has additive ergogenic effects when combined with CIT is unknown. This randomized, double-blind, placebo-controlled crossover trial aimed to compare the acute effects of CIT versus citrulline malate (CMA) supplementation on neuromuscular performance and exertion and emotional perceptions in young, trained men and women. 43 (21 women; 24.

Background & Aims: The aim of this study was to investigate the potential ergogenic effects of intra-session supplementation of highly branched cyclic dextrin (HBCD) on mechanical (number of repetitions completed and repetition velocity), metabolic (lactate concentration), and perceptual (gastrointestinal complaints and ratings of perceived exertion [RPE]) responses to resistance training.
Methods: This study used a randomized, double-blinded, placebo-controlled crossover study design. Thirty physically active individuals (15 men and 15 women) completed two experimental sessions that only differed in the supplement condition (placebo or HBCD).

J Strength Cond Res 38(11): e638-e644, 2024-This study examined the effects of using lifting straps in the prone bench pull exercise on (a) the magnitude of the load-velocity (L-V) relationship variables (load-axis intercept, velocity-axis intercept, and area under the L-V relationship line) and (b) the accuracy of the L-V relationship in predicting the 1 repetition maximum (1RM).

The current study employed a randomized, triple-blinded, placebo-controlled and crossover experimental design to explore the acute effects of caffeine (200 mg), beta-alanine (3 g), or their combination (200 mg caffeine and 3 g beta-alanine; C+B-A) administered 30 min prior to resistance training (RT) on mechanical, physiological, and perceptual variables.

View Article and Find Full Text PDFBackground: The fastest mean (MV) and peak (PV) velocity in a set are used to predict the maximum number of repetitions (RTF), but stretch-shortening cycle (SSC) effects on these relationships are unknown.
Hypothesis: Velocity values associated with each RTF would show higher values for eccentric-concentric and multiple-point methods compared with concentric-only and 2-point methods.
Study Design: Cross-sectional study.
Purpose: To explore the association of the load-velocity (L-V) relationship variables and ability to maintain maximal mechanical performance during the prone bench-pull exercise with sprint swimming performance and in-water forces.
Methods: Eleven competitive adult male swimmers (50-m front crawl World Aquatics points: 488 [66], performance level 4) performed 1 experimental session. The L-V relationship variables (L0 [ie, maximal theoretical load at 0 velocity]; v0 [ie, maximal theoretical velocity at 0 load], and Aline [ie, area under the L-V relationship]) and maximal mechanical maintenance capacity were assessed at the beginning of the session.
Background: Fastest mean (MV) and peak (PV) velocity of the set have been proposed to predict the maximum number of repetitions to failure (RTF) during the Smith machine prone bench pull (PBP) exercise.
Hypothesis: Goodness-of-fit would be higher for individualized compared with generalized RTF-velocity relationships and comparable for both execution equipment conditions (with or without straps), and the MV and PV associated with each RTF would be comparable between execution equipment and prediction methods (multiple- vs 2-point method).
Study Design: Cross-sectional study.
This study examined the influence of inter-set rest periods of 1 (R1), 3 (R3) and 5 (R5) minutes on the number of repetitions completed before exceeding the minimum velocity thresholds of 0.45 m⋅s (MVT) and 0.35 m⋅s (MVT) during the bench press exercise.
View Article and Find Full Text PDFThis study aimed to explore whether the relationship between perceptual (rating of perceived exertion; RPE) and mechanical (maximal number of repetitions completed [MNR], fastest set velocity, and mean velocity decline) variables is affected by the length of inter-set rest periods during resistance training sets not leading to failure. Twenty-three physically active individuals (15 men and eight women) randomly completed 12 testing sessions resulting from the combination of two exercises (bench press and bench pull), three inter-set rest protocols (1, 3, and 5 min), and two minimal velocity thresholds (farther from muscular failure [MVT for bench press and MVT for bench pull] and closer to muscular failure [MVT for bench press and MVT for bench pull]). The duration of inter-set rest periods did not have a significant impact on RPE values ( ranged from 0.

Twenty-three resistance-trained males randomly performed 2 sessions during Smith machine PBP and 2 sessions during free-weight PBP in different weeks. The first weekly session determined the RTF-MV relationships and subjects completed single sets of repetitions to failure against 60-70-80-90%1RM.

Method: In a single testing session, the military-specific Simple and Go, No-Go RT, aerobic power (20-m Multistage Shuttle Run test), maximal upper- and lower-body mechanical capacities (bench press and squat against different loads), and visual skills (multiple object tracking and dynamic visual acuity) of 30 young men (15 active-duty military personnel and 15 sport science students) were evaluated.
