Effect of Collagen Peptides, in Combination With Resistance Training, on Body Composition and Muscle Strength in Untrained Men
Study Details
Study Description
Brief 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 plasma lipid profile 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).

Detailed 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 and plasma lipid profile
Participants are healthy untrained overweight males (30-60 yrs)
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Collagen peptide group This group will consume 1 serving of Collagen peptides, which is produced and marketed ® by GELITA AG, Germany under the brand name BODYBALANC each day. |
Dietary Supplement: Effect of collagen peptides, in combination with resistance training, on body composition and muscle strength compared to placebo in untrained men
The effects of collagen peptide consumption in combination with resistance training will be tested
|
| Placebo Comparator: Placebo group This group will consume 1 serving of silicon dioxide (Sipernat 350, Evonik, Germany) each day. The product is absorbed in negligible amounts by the intestine and does therefore induce minor metabolic effects. |
Dietary Supplement: Placebo Control intervention: Effect of resistance training in combination with placebo (silicon dioxide), on body composition and muscle strength in untrained men
The effects of placebo consumption in combination with resistance training will be tested

Other Outcome Measures
- Dietary intake [Pre (1 week prior to intervention) and during the intervention period (week 10 if the intervention) - N/A]
