Brief Summary:
The aim of this project is to investigate the potential benefits of combining a new protein meat hydrolysates extract with a regular endurance training programme on (a) body composition (b) performance (c) muscle structure (d) immunology and (e) microbiota (f) haematological markers in endurance athletes
Detailed Description:
PROYECT DESIGN This investigation involves a 10-week randomised, balanced, double blind parallel group between-subjects design, aimed to analyse the effects of combining endurance exercise and a post exercise nutrition strategy (hydrolysates meat protein (MEAT) + whey protein (W) or a isocaloric only carbohydrate placebo) on training outcomes, immunity and haematological variables after regular training and feeding intervention.
Participants will be divided in two-treatment groups 1) Hydrolysed meat-protein + whey (PROT); and 2) non-protein iso-energetic placebo (CHO). Once considered eligible for the study, and after an initial familiarisation period plus baseline tests (endurance performance body composition and blood extractions) participants will be randomly assigned to one of the intervention groups: PROT and CHO. Each group will follow a 10-week periodised endurance training intervention combined with one of the two specific supplementation treatments (PROT or CHO). Measurements of performance (VO2peak, vetilatory threshold and time to exhaustion at maximal aerobic intensity), body composition (fat and fat free mass), microbiota and haematology will be determined before and after the 10-week intervention period.
Once informed consent and health history have been obtained, after the baseline assessment (t1), participants will be divided into two similar profile groups, matched by body mass, age, sex and maximal oxygen uptake (VO2peak): (1) PROT (2) CHO
INTERVENTION The intervention will comprise of a 10-week combined supplementation (MEAT + W and CHO) regular endurance-training programme.
Endurance training Participants will commit to follow a polarised triphasic endurance-training model. This model contains three intensity zones calculated as low intensity \[\< the first ventilatory threshold (VT1), \~ 70% HRmax\]; moderate intensity \[between VT1 and respiratory compensation point or ventilatory threshold 2 (VT2), \>70 \< 90% HRmax\]; and high intensity \[\>VT2, 90% HRmax\]. Participants will train 5 to 6 times 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.
Cardiorespiratory test Participants will perform a maximal cardiorespiratory exercise test before the training period to determine peak oxygen uptake (VO2peak) and ventilatory thresholds. Percentage of HRmax and the 15 points (6 to 20) Borg Scale Rate of Perceive Exertion (RPE) will be used to appropriately select the load along the training intervention.
Supplementation protocol Training days: Immediately (\<10 min) after completing each training session, participants will consume a beverage containing 20g of supplement (10g MEAT + 10g W) plus 200 ml of orange juice or only carbohydrate placebo (maltodextrine and orange juice).
Non-training days: before breakfast.
Supplements and placebo will be provided in powder form and should be mixed with 200ml of orange juice and water at the moment of consumption.
The supplements and placebo will look and taste identical.
Thus a total of one 20g doses will be administered on a daily base. Participants are required to ingest a total of 70 for the total of 10 weeks of the study intervention.
Supplements will be provided in 14 days intervals and distributed by a blinded researcher after participants return the empty bag of the supplement/placebo consumed during the previous 14 day period.
