About this study

This study investigates whether taking daily collagen peptides, combined with long-term endurance or concurrent training can enhance running economy through muscle and/or tendon adaptations.

Read the detailed description

An adequate and high-quality intake of proteins and amino acids is crucial for synthesizing the body's own connective tissue-like structures, such as muscles, tendons, ligaments, and bones. Various metabolic and hormonal processes are regulated or influenced by proteins. It is undisputed that measurable improvements are only possible through the combination of training and protein intake. Simply increasing protein intake without physical activity cannot be expected to result in structural or metabolic adaptations.

In recent years, interest in regular collagen intake in sports nutrition, particularly in connection with moderate to intense physical activity, has increased. Since collagen and its peptides are primarily found in force-transmitting structures such as tendons, studies have been conducted to examine how tendons adapt to collagen peptide supplementation. Studies by Jerger et al. (2022 \& 2023) have shown that both the patellar and Achilles tendons adapt to collagen supplementation, as evidenced by an increased cross-sectional area compared to a non-caloric placebo. This increase allows tendons to withstand greater forces, making them more resilient and thus playing an important role in injury prevention. These results were achieved with a dose of 5g of collagen combined with three months of strength training.

Additionally, multi-month collagen peptide supplementation combined with concurrent training (strength and endurance training in one session) led to improved endurance performance. Both running distance and speed at the aerobic and anaerobic thresholds significantly increased compared to a placebo group with a daily intake of 15g of collagen over three months (Jerger et al. 2023, Jendricke et al. 2020).

Based on these results, the question arises as to whether regularly supplemented collagen peptides, combined with pure endurance training, lead to similar metabolic and/or tendon-specific adaptations. Therefore, the aim of this proposed study is to investigate both metabolic and specific (morphological, mechanical, and material) properties of the Achilles and patellar tendons to determine the mechanism through which the so-called "running economy" develops in connection with collagen peptides. The results will be compared to those of concurrent training, which has already shown metabolic adaptations as described above.

Questions about this trial

What is this clinical trial studying?

A study testing ColCT, ColET and PlaCT in people with Collagen Supplementation, run by University of Vienna at 1 site in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 14 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

One-hour time trial performance (time frame: Baseline and after 12 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2024.
