Effects of a Recovery Supplement on Body Composition, Performance, Muscular Properties, and Wellbeing
Condition: Protein Deficiency; Training Group, Sensitivity; Fatigue; Muscular Atrophy; Psychological
MeSH terms: Muscular Atrophy; Protein Deficiency; Fatigue
Study type: Interventional

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.
    

Intervention name(s): Ingestion of a Post-Workout Supplement; Ingestion of a Maltodextrin Supplement
Intervention type(s): Dietary Supplement; Dietary Supplement
Intervention description(s): The Post-Workout Supplement is administered 15 minutes after the completion 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.; The Maltodextrin Supplement is administered 15 minutes after the completion of training sessions. No supplementation is administered in non-training days. The Resistance Training is performed in alternate days.
