Effect of collagen peptides, in combination with resistance training, on body composition and muscle strength compared to placebo in untrained men

Clinical Study ID

NCT06061315
7260992052
  • Ages 30-60
  • Male
  • Accepts Healthy Volunteers

Study Summary

The effect of resistance training with post-exercise Collagen peptides (CP) supplementation on lean body mass, maximal and explosive, isometric muscle strength as well as fat mass, resting metabolism, health parameters and compared to resistance training alone will be evaluated in a group of untrained overweight male (30-60 yrs) population in a randomized controlled trial (RCT).

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Male, between 30 and 60 years of age

  • Fat mass >25 % as measured by bioelectrical impedance analysis

  • Stable weight (±5 %) and eating behaviour within the last 3 months.

  • Signed informed consent

Exclusion

Exclusion Criteria:

  • Regular physical activity >60 min / week

  • Stabile or progressive diseases/conditions (including medication) contraindicatingor disabling participation in intensive exercise training and/or with potential toaffect training adaptation beyond normal variation. For example:

  • Contraindications against physical stress corresponding guidelines of AmericanCollege of Sports Medicine (ACSM)

  • Subjective symptoms during exercise (e.g., unusual physical exhaustion, dyspnoea,nausea)

  • Moderate to severe mobility limitation (i.e., due to rheumatic disease)

  • Diagnosis of cancer within the last 5 years

  • Diabetes mellitus I and II uncontrolled arterial hypertension (systolic bloodpressure >155 for mmHg and/or diastolic blood pressure >94 mm Hg; mild hypertensionunder resting condition will be allowed but such participants will be recommended toconsult their general practitioner).

  • Conditions contraindicating the supplementation protocol.

  • Contraindications against nutritional or ergogenic supplements

  • Allergy/aversion against animal protein

  • Liver or kidney diseases with a non-permission to ingest certain concentrations ofprotein.

Study Start date:
September 15, 2023
Estimated Completion Date:
November 23, 2024

Study Description

Participants will perform supervised resistance training involving (Leg press, pull down, chest press, back extension and abdominal crunches) 3 times a week for 12 weeks. Participants will consume either placebo or collagen peptides (in a double blinded study design) just following resistance training on training days (And approximately the same time of day on non-training days). Prior to, and following 12 weeks of exercise, participants will be tested in body composition, maximal and explosive, isometric muscle strength, resting metabolism, health parameters. Additionally, blood samples will be taken to ensure health and training eligibility and safety.

Participants are healthy untrained overweight males (30-60 yrs)
