About this study

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.

Treatment and study plan

Pre-Workout Supplement

Dietary Supplement

One week familiarisation, one-week training, two weeks washout period and one-week training.

15 Minutes before every training, the Pre-Workout Arm (PRE-W) will take a Supplement shake, consisting of some ingredients (Multi-Ingredient, explained before) and the Placebo Comparator Arm (CHO) will drink a Placebo shake, consisting of Maltodextrin.

Other names: Multi-Ingredient Supplement

Resistance training

Other

-Resistance Training days (Monday-Wednesday-Friday): Before training starts, Tensiomyography and Energy Feeling will be assessed (Energy Level, Fatigue Level, Feeling of Alertness, and Feeling of Focus on the task). Immediately after finishing, Tensiomyography and Performance (Vertical Jump, Overhead Medicine Ball Throw, and Maximal Mid-Tigh Pull Isometric Strength) will be assessed. Training Protocol: 10 minutes of standardized warm-up, Strength Circuit training using free weights (Parallel Squat; Bench Press; Alternate Box Set-Ups; Shoulder Press; Alternate Lunges; Up-right Row; Hip-Thrust; Squat on Isoinertial Fly-Wheel or Drop Jump). The participants will have to 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 will be added for the next set. Also, whole-body Perceptual Response will be assessed using the 0-10 OMNI-RES Scale, after every set and 15 minutes after finishing.

Other names: Free Weights Training

Endurance training

Other
  • Endurance Training days (Tuesday-Thursday): Energy Feeling Questionnaire will be implemented before training. The training will consist of 30 minutes cycling at their Fatmax Intensity (~60% Vo2max) on a Cycloergometer (estimated during familiarisation week). Also, the Heart Rate will be recorded during the whole training. Besides, Perception of Effort will be assessed using the 6-20 version of the Borg Scale every 5 minutes during training and 15 minutes after it has been completed.

Other names: Cycloergometer Training

Primary outcomes

  1. Tensiomyography

    Time frame: Changes from 10 minutes Previous to post 1 hour after the completion of each workout session

    Fatigue and contractility assessment via Tensiomyography will be assessed in Biceps Femoris Long Head, Vastus Medialis, and Anterior Deltoid.

  2. Vertical Jump

    Time frame: Changes from 10 minutes Previous to post 1 hour after the completion of each resistance training workout session

    Flight Time (measured in seconds).

  3. Over Head Medicine Ball Throw

    Time frame: Changes from 10 minutes Previous to post 1 hour after the completion of each resistance training workout session

    Medicine Ball Throw (measured in meters and centimeters).

  4. Maximal Mid-Thigh Pull Isometrical Strength

    Time frame: Changes from 10 minutes Previous to post 1 hour after the completion of each resistance training workout session

    Maximal Strength (measured in kilograms).

  5. Self Perceived Energy Feeling

    Time frame: Before every Training Session and up to 1 week of training.

    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).

Secondary outcomes

  1. Whole Body Perceptual Response during Resistance Training

    Time frame: Differences between first week and second week of training.

    Self Rate of Perceived Exertion (RPE) will be assessed via OMNI RES Scale (0-10 values) during resistance training (after every circuit) and 15-20 minutes after finishing each session.

  2. Perception of Effort during Endurance Training.

    Time frame: Differences between first week and second week of training

    Borg Scale (6-20) will be used to collect the perception of effort during endurance training (every 5 minutes) and 15-20 minutes after each session.
