Brief Summary

The aim of this project is to investigate the potential benefits of combining a new protein beef hydrolysates extract with a regular endurance training programme on (a) body composition (b) performance (c) muscle structure (d) blood markers of health in athletes. As a second objective the investigators will analyse potential differences obtained from the ingestion of the new hydrolysates beef protein extract compared to the ingestion of others commercially available protein sources such as whey and non protein only carbohydrate contrast nutrients.

Study Arms (3)

Dietary Supplement: Beef Protein

EXPERIMENTAL

All the groups will perform a similar endurance training involved 4 to 6 workout per week with a total percentage distribution of 75 to 80% at low intensity; 10% at moderate intensity, and 15 to 10% at high intensity. Training session will last from 45 min to a maximum of 120 min. Intervention will last for 10 weeks. Participants will ingest 20g of beef protein powder mixed with 250ml of water at post workout (training days) or before breakfast (non training days).

Dietary Supplement: Whey Protein

ACTIVE COMPARATOR

All the groups will perform a similar endurance training involved 4 to 6 workout per week with a total percentage distribution of 75 to 80% at low intensity; 10% at moderate intensity, and 15 to 10% at high intensity. Training session will last from 45 min to a maximum of 120 min. Intervention will last for 10 weeks. Participants will ingest 20g of maltodextrin powder mixed with 250ml of water at post workout (training days) or before breakfast (non training days).

Interventions

Dietary Supplement: Beef Protein DIETARY_SUPPLEMENT

Participants will combine a 10-week periodized and controlled endurance programme with the ingestion of beef protein supplement after training. Measurements pre and post intervention will be endurance performance (vo2max) and blood markers: haemoglobin; red blood cell; erythrocyte; haematocrit; mean corpuscular volume, transferrin; neutrophils; lymphocyte; monocytes
