The effect of specific bioactive collagen peptides on function and muscle remodeling during human resistance training. Acta Physiol. 2023;237:e13903. doi:10.1111/apha.13903In the published article, the dietary analysis result section text and corresponding results table (Table 1) have been modified due to an error with one participant's dietary analysis data within the collagen peptide (CP) supplementation group. Mean and SD values have been updated for accuracy as have unpaired t-test p values, but this error does not alter statistical outcomes or the interpretation of the dietary analysis data, or any other data within the article.

The Effect of Specific Bioactive Collagen Peptides on Tendon Remodelling during 15 Weeks of Lower Body Resistance Training
No full textPurpose
Collagen peptide supplementation has been reported to enhance synthesis rates or growth in a range of musculoskeletal tissues and could enhance tendinous tissue adaptations to resistance training (RT). This double-blind placebo-controlled study aimed to determine if tendinous tissue adaptations, size (patellar tendon cross-sectional area [CSA] and vastus lateralis [VL] aponeurosis area) and mechanical properties (patellar tendon), following 15 weeks of RT could be augmented with collagen peptide (CP) vs. placebo (PLA) supplementation
Methods
Young healthy recreationally active men were randomized to consume either 15 g of CP (n=19) or PLA (n=20) once every day during a standardized program of lower-body RT (3 times/wk). Measurements pre- and post-RT included: patellar tendon CSA and VL aponeurosis area (via MRI); patellar tendon mechanical properties during isometric knee extension ramp contractions.
Results
No between-group differences were detected for any of the tendinous tissue adaptations to RT (ANOVA group x time, 0.365 ≤ P ≤ 0.877). There were within-group increases in VL aponeurosis area (CP: +10.0%, PLA: +9.4%), patellar tendon stiffness (CP: +17.3% PLA: +20.9%) and Young’s Modulus (CP: +17.8%; PLA: +20.6%) in both groups (paired t-tests [all] P ≤ 0.007). There were also within-group decreases in patellar tendon elongation (CP: -10.8%, PLA: -9.6%) and strain (CP: -10.6%, PLA: -8.9%) in both groups (paired t-tests [all] P ≤ 0.006). Whilst no within-group changes in patellar tendon CSA (mean or regional) occurred for CP or PLA, a modest overall time effect (n=39) was observed for mean (+1.4%) and proximal region (+2.4%) patellar tendon CSA (ANOVA, 0.017 ≤ P ≤ 0.048).
Conclusions
In conclusion, CP supplementation did not enhance RT-induced tendinous tissue remodelling (either size or mechanical properties) compared to PLA within a population of healthy young males
The effect of specific bioactive collagen peptides on function and muscle remodeling during human resistance training
No full textAim: Bioactive collagen peptides (CP) have been suggested to augment the functional, structural (size and architecture), and contractile adaptations of skeletal muscle to resistance training (RT), but with limited evidence. This study aimed to determine if CP vs. placebo (PLA) supplementation enhanced the functional and underpinning structural, and contractile adaptations after 15 weeks of lower body RT. Methods: Young healthy males were randomized to consume either 15 g of CP (n = 19) or PLA (n = 20) once every day during a standardized program of progressive knee extensor, knee flexor, and hip extensor RT 3 times/wk. Measurements pre‐ and post‐RT included: knee extensor and flexor isometric strength; quadriceps, hamstrings, and gluteus maximus volume with MRI; evoked twitch contractions, 1RM lifting strength, and architecture (with ultrasound) of the quadriceps. Results: Percentage changes in maximum strength (isometric or 1RM) did not differ between‐groups (0.684 ≤ p ≤ 0.929). Increases in muscle volume were greater (quadriceps 15.2% vs. 10.3%; vastus medialis (VM) 15.6% vs. 9.7%; total muscle volume 15.7% vs. 11.4%; [all] p ≤ 0.032) or tended to be greater (hamstring 16.5% vs. 12.8%; gluteus maximus 16.6% vs. 12.9%; 0.089 ≤ p ≤ 0.091) for CP vs. PLA. There were also greater increases in twitch peak torque (22.3% vs. 12.3%; p = 0.038) and angle of pennation of the VM (16.8% vs. 5.8%, p = 0.046), but not other muscles, for CP vs. PLA. Conclusions: CP supplementation produced a cluster of consistent effects indicating greater skeletal muscle remodeling with RT compared to PLA. Notably, CP supplementation amplified the quadriceps and total muscle volume increases induced by RT

Methods: Young healthy recreationally active men were randomized to consume either 15 g of CP (n = 19) or PLA (n = 20) once every day during a standardized program of lower-body RT (3 times a week). Measurements pre- and post-RT included patellar tendon CSA and VL aponeurosis area (via magnetic resonance imaging), and patellar tendon mechanical properties during isometric knee extension ramp contractions. Results: No between-group differences were detected for any of the tendinous tissue adaptations to RT (ANOVA group–time, 0.365 ≤ P ≤ 0.877). There were within-group increases in VL aponeurosis area (CP, +10.0%; PLA, +9.4%), patellar tendon stiffness (CP, +17.3%; PLA, +20.9%) and Young’s modulus (CP, +17.8%; PLA, +20.6%) in both groups (paired t-tests (all), P ≤ 0.007). There were also within-group decreases in patellar tendon elongation (CP, −10.8%; PLA, −9.6%) and strain (CP, −10.6%; PLA, −8.9%) in both groups (paired t-tests (all), P ≤ 0.006).
