Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: One week training (3 days Resistance Training and 2 Endurance Training in alternate days) with a Pre-Workout Supplement or Maltodextrin. 2 Weeks wash out period and then change supplement.
Primary purpose: TREATMENT

Brief summary: The investigation will be conducted as a double blinded, randomized, crossover within-participant comparison design with two 1-week intervention periods separated by 2-weeks for wash out, recovery, period.

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 take a 5-day microcycle, involving three resistance training sessions (Monday, Wednesday and Friday) intercalated with two endurance training sessions (Tuesday and Thursday). After the first interventional microcycle, and the 2-week washout period, the participants will switch to the other nutritional condition for continuation with the second 5-day identical microcycle. Assessments of muscle contractile properties via Tensiomyography on Vastus Medialis, Biceps Femoris Long Head and Anterior Deltoids will be taken before and after each resistance training session. Measurements of strength (Isometric Mid Thigh Pull) upper and lower body muscular power (Medicine Ball Throw and Vertical Jump) will be performed immediately after each resistance training workout. The supplements will be ingested 15 min before each training session, just before completing an energy feeling questionnaire. In addition, the perceptual response to training will be assessed during and 20 min after the completion of all workouts. The contribution of carbohydrate and fat metabolism will be estimated using a gas analyzer via the calculation of respiratory exchange ratio the (RER) during each endurance training session.
