• Conditions: Psychological; Protein Deficiency; Fatigue; Muscular Atrophy; Training Group, Sensitivity
• Interventions: Dietary Supplement: Ingestion of a Maltodextrin Supplement; Dietary Supplement: Ingestion of a Post-Workout Supplement

• Registration Number: NCT05769101
• Lead Sponsor: Joel Puente

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.

Primary Outcome Measures

Name	Time	Method
Vertical Jump	Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program	Height (measured in centimetres)
Muscle Thickness	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: 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	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	Changes from 3 days previous to, and 3 days after the completion of the 6-weeks training program	Distance (measured in centimetres)
