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, pre-workout supplement (PREW) 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 15 min before 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.

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Ingestion of a Pre-Workout Supplement	The Multi-Ingredient Pre-Workout Supplement is administered 15 minutes before the beginning of training sessions. No supplementation is administered in non-training days. The Resistance Training is performed in alternate days. The training Protocol is: 10 minutes of standardized warm-up, Strength Circuit training using free weights (Alternate Box Step-Ups, Bench Press; Parallel Squat; Up-right Row; Deadlift; Alternate Lunges; Shoulder Press; Leg Extension). The participants perform 16 repetitions of each exercise, with 30 seconds rest and 3 minutes rest after every set. If they can complete 16 repetitions easily, 2.5 to 5 kg are added for the next set. Also, whole-body Perceptual Response is assessed using the 0-10 OMNI-RES Scale, after every set and 15 minutes after finishing.
DIETARY_SUPPLEMENT	Ingestion of a Maltodextrin Supplement	The Maltodextrin Supplement is administered 15 minutes before the beginning of training sessions. No supplementation is administered in non-training days. The Resistance Training is performed in alternate days. The training Protocol is: 10 minutes of standardized warm-up, Strength Circuit training using free weights (Alternate Box Step-Ups, Bench Press; Parallel Squat; Up-right Row; Deadlift; Alternate Lunges; Shoulder Press; Leg Extension). The participants perform 16 repetitions of each exercise, with 30 seconds rest and 3 minutes rest after every set. If they can complete 16 repetitions easily, 2.5 to 5 kg are added for the next set. Also, whole-body Perceptual Response is assessed using the 0-10 OMNI-RES Scale, after every set and 15 minutes after finishing.
