Brief Summary:
The aim of this project is to investigate the potential benefits of combining a new protein meat hydrolysates extract with a regular resistance training programme on (a) body composition (b) performance (c) muscle structure (d) general markers health and immunity in athletes. As a second objective the investigators will analyse potential differences obtained from the ingestion of the new hydrolysates meat protein extract compared to the ingestion of others commercially available protein sources such as whey or casein.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effects of Meat Protein Administration on Body Composition, Strength, Muscle Structure and Markers of Muscle Damage and Health in Athletes
Study Start Date : February 2015
Actual Primary Completion Date : March 2015
Actual Study Completion Date : April 2015

Arm Intervention/treatment
Experimental: Meat protein
Post workout (training days) or breakfast (non training days) 20g of meat protein mixed with 250ml of orange juice and water
Dietary Supplement: Meat Protein
Immediately (<10 min) after completing each training session (resistance training or sport specific workout), participants will consume a beverage containing 20g of meat protein mixed with 250 ml of orange juice and water. On non-training days supplement will be ingested before breakfast.

Experimental: Whey Protein
Post workout (training days) or breakfast (non training days) 20g of whey protein isolate mixed with 250ml of orange juice and water
Dietary Supplement: Whey protein
Immediately (<10 min) after completing each training session (resistance training or sport specific workout), participants will consume a beverage containing 20g of whey protein mixed with 250 ml of orange juice and water. On non-training days supplement will be ingested before breakfast.

Active Comparator: Carbohydrate
Post workout (training days) or breakfast (non training days) maltodextrin mixed with 250ml orange juice and water
Dietary Supplement: Carbohydrate
Immediately (<10 min) after completing each training session (resistance training or sport specific workout), participants will consume a beverage containing about 20g of maltodextrin mixed with 250 ml of orange juice and water. On non-training days supplement will be ingested before breakfast.
