“…Both components indeed may be influenced by the cuff pressure [ 9 ], especially during the rest time between the sets. Previous studies indicated a SmO 2 between 80 and 85% [ 27 ] during the rest time between the sets of an upper-body resistance exercise protocol. In the present investigation, SetO 2 was between 45% and 50% in HP and between 65% and 70% in LP.…”

“…In particular, a high cuff pressure reduced the SmO 2 during the rest time between the sets to a greater extent compared to a lower cuff pressure. Contrarywise, the muscle oxygenation at the end of each set (SetO 2 ) was similar compared to a regular resistance exercise set to volitional failure performed with light loads (between 0 and 10%) [ 27 ].…”

The aim of the study was to compare the recovery response and muscle oxygenation of a blood-flow restriction resistance exercise (BFR) session with high [HP: 80% of the arterial occlusion pressure (AOP)] and low cuff pressure (LP: 40% of AOP). Both exercise sessions included 4 sets to failure at the barbell preacher curl exercise. Twelve resistance trained men (27.4 ± 5.0 years; 83.5 ± 11.6 kg; 176.6 ± 7.0 cm) performed each protocol in a counterbalanced, randomized order. Maximal isometric force, muscle morphology and muscle soreness of the biceps brachii muscle were assessed at baseline, 15-min, 60-min and 24-h post each testing session. In addition, muscle oxygen saturation (SmO2) was assessed during each training session. A lower number of repetitions (p = 0.013) was detected in HP compared to LP. A lower SmO2 (p < 0.001) was detected in the recovery time between the sets in HP (mean: 47.6 ± 15.7%) compared to LP (mean: 68.9 ± 7.2%). No differences between the two trials (p > 0.05) were noted for isometric force, muscle architecture and soreness at any timepoint. Results indicate that, despite a high cuff pressure may induce a more hypoxic condition compared to a lower cuff pressure, recovery responses may not be affected.

“…Next, participants were familiarized with an IMTP test (3 attempts) and assessed for a barbell bench press 1RM. The 1RM strength for the barbell bench press exercise was determined by applying a prediction formula based on the number of repetitions performed to fatigue using a fixed weight [ 24 ] and the methods previously described [ 25 ]. A certified strength and conditioning specialist monitored and enforced proper technique.…”

L-citrulline serves as a nitric oxide precursor with the potential to increase blood flow and improve resistance exercise performance, yet more research is needed to examine its ergogenic potential. To examine the effect of L-citrulline supplementation on resistance exercise performance, muscle oxygenation, and the subjective perception of effort, energy, focus, fatigue, and muscle pump, eighteen resistance-trained men (n = 11) and women (n = 7) (21.4 ± 1.8 years; 172.3 ± 7.5 cm; 76.9 ± 10.8 kg) were randomly assigned for supplementation with 8 g of L-citrulline (CIT) or a placebo (PL) in a cross-over fashion one hour prior to testing. Participants completed an isometric mid-thigh pull test (IMTP), a ballistic bench press protocol [two sets of two repetitions at 75% 1-repetition maximum (1 RM) with maximum ballistic intent], and a strength-endurance bench press protocol [five repetition-maximum sets at 75% 1RM]. Barbell velocity and power were measured via a linear position transducer during the ballistic protocol, while the repetitions completed, volume load and muscle oxygenation were quantified during the strength-endurance protocol. Subjective measures were assessed at the baseline and immediately pre- and post-exercise. Repeated measures of the analysis of variance and Bayesian equivalents revealed no significant interactions, providing evidence favoring the null hypothesis (BF10 < 1) for IMTP (PL 497.5 ± 133.6 vs. CIT 492.5 ± 129.4 N), barbell velocity, and power, and repetitions completed (PL 36.7 ± 7.2 vs. CIT 36.9 ± 8.1 repetitions). There were also no significant interactions for muscle oxygenation parameters or subjective measures except perceived fatigue. Women reported greater fatigue across all time points compared to men (~1.88 au, p = 0.045, BF10 = 0.2). The results indicate that a single 8 g dose of L-citrulline did not enhance isometric force production, muscle endurance, or muscle oxygenation parameters during the protocol implemented in this study.

“…Gonzalez et al [ 59 ] noted that 8 g of CitMal did not induce significant enhancement in triceps brachii muscle thickness following a high-volume bench press protocol. Likewise, 7 days of watermelon juice supplementation (2.2 g·day −1 L-citrulline) also failed to enhance indirect measures of blood flow surrounding a high-volume bench press protocol including brachial artery diameter, muscle oxygenation parameters, and subjective measures of “muscle pump” [ 60 ]. Thus, evidence supporting an enhancement in vasodilation, blood flow, and muscle perfusion is currently limited in resistance exercise research.…”

“…Cutrufello et al [ 57 ] observed that neither a single dose of watermelon juice (containing ~1 g of L-citrulline) nor a single 6 g dose of L-citrulline enhanced repetitions to failure during five sets of machine chest press at 80% 1RM in recreationally trained men and women. Lastly, Gonzalez et al [ 60 ] provided resistance-trained men with a watermelon juice concentrate (containing 2.2 g·day −1 L-citrulline) for 7 days prior to an experimental trial consisting of an isometric mid-thigh pull test and an acute bench press protocol. This study showed that short-term watermelon supplementation did not enhance isometric force production, barbell velocity, or bench press repetitions to failure during five repetition-maximum sets at 75% 1RM.…”

Supplementation with Nitric Oxide Precursors for Strength Performance: A Review of the Current Literature

Nitric-oxide-stimulating dietary supplements are widely available and marketed to strength athletes and weightlifters seeking to increase muscle performance and augment training adaptations. These supplements contain ingredients classified as nitric oxide (NO) precursors (i.e., “NO boosters”). Endogenous NO is generated via a nitric oxide synthase (NOS)-dependent pathway and a NOS-independent pathway that rely on precursors including L-arginine and nitrates, with L-citrulline serving as an effective precursor of L-arginine. Nitric oxide plays a critical role in endothelial function, promoting relaxation of vascular smooth muscle and subsequent dilation which may favorably impact blood flow and augment mechanisms contributing to skeletal muscle performance, hypertrophy, and strength adaptations. The aim of this review is to describe the NO production pathways and summarize the current literature on the effects of supplementation with NO precursors for strength and power performance. The information will allow for an informed decision when considering the use of L-arginine, L-citrulline, and nitrates to improve muscular function by increasing NO bioavailability.
