Study Overview
Brief Summary
The investigation will be conducted as a double blinded, randomized, parallel between treatment conditions comparison design with two different groups ingesting a different supplement each one.
Detailed Description
Following inclusion, familiarization and baseline assessments, the participants will be randomly allocated to receive either a multi-ingredient, post-workout supplement (REC) or maltodextrin (CHO). Thereafter, the participants will follow a 6-weeks resistance training mesocycle, involving three resistance training sessions (Monday, Wednesday and Friday) per week (18 sessions in total). Before and after the 6 weeks of intervention, the following assessments will be performed: (i) Body composition (fat mass and fat-free mass) via air displacement plethysmography (BodPod); (ii) muscle contractile properties on Vastus Medialis and Anterior Deltoids (via Tensiomyography; (iii) muscle structure of the Vastus Lateralis of the Quadriceps and the Elbow Flexors of dominant extremities via Ultrasound; (iv) Maximal Isometric Strength (Isometric Mid-Thigh Pull); (v) Upper and Lower Body Muscular Power (Medicine Ball Throw and Vertical Jump), (vi) Upper and Lower Muscular Endurance (30- Seconds Sit-to-Stand and 30-Seconds 16RM Bench Press), (vii) Immune System (via HemoCue WBC DIFF System).
The supplements will be ingested immediately (within 15 min) after each training session.
Energy Feeling Questionnaire will be filled immediately before warming up.
In addition, Rate of Perceived Exertion to training will be assessed 15 min after the completion of all workouts.

Outcomes
Primary Outcomes
Vertical Jump
Time Frame: Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program
Height (measured in centimetres)
Muscle Thickness
Time Frame: Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program
Thickness of the Vastus Lateralis and the Elbow Flexors of the dominant limbs
Self Perceived Energy Feeling
Time Frame: [Time Frame: Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program]
All participants will fill a short questionnaire (from 1 to 5 points) about their perception of energy before every training. Energy Feeling will be assessed (Evergy level, Fatigue Level, Feeling of Alertness, and Feeling of Focus for the task, valued from 1 = low energy to 5 = high energy).
White Blood Cells count
Time Frame: Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program
White blood cell (WBC) count including a five-part differential
Chest Medicine Ball Throw
Time Frame: Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program
Distance (measured in centimetres)
Secondary Outcomes
No secondary outcomes reported
