Brief summary
This study aims at investigating the metabolic cost of several fundamental exercises with sandbag. Sandbag training has become a popular training modality that is efficiently used to improve cardiovascular status and physical performance. Despite its widespread use and popularity the metabolic cost of exercises using sandbag remains to be elucidated. Therefore, the metabolic cost of various fundamental exercise with sandbag will be determined to aid the planning of exercise training programs.
Detailed description
Ten healthy young adults will be assigned to this study. Participants will initially undergo a baseline assessment of their anthropometrics, body composition (by DXA), resting metabolic rate (RMR), cardiorespiratory fitness (VO2max), muscular strength \[maximal strength (1RM) and muscular endurance\] and functional capacity. After baseline screening, participants will execute in different days (one exercise per day) one set of each of the following 8 exercise: (1) lateral bag drag, (2) dead bag, (3) shoulder to shoulder thruster, (4) sumo DL with pull, (5) front lunge, (6) single leg RDL, (7) reverse lunge with rotation and (8) clean, in two different conditions: (i) 30 sec and (ii) 45 sec exercise duration, in a random order. Prior to each exercise resting heart rate, blood lactate concentration, oxygen consumption and rate of perceived exertion will be recorded. Heart rate and oxygen consumption (through portable gas analyzer) will be continuously monitored during the exercise and after the end of it, until the oxygen consumption reach the pre-exercise values (excess post-exercise oxygen consumption). Blood lactate and rate of perceived exertion will be reassessed post-exercise.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in recovery energy expenditure | At pre-exercise and up to 15 minutes after the exercise (a single set lasting 30 or 45 seconds) | The contribution of excess post-exercise oxygen consumption in exercise energy expenditure will be assessed by the change in oxygen consumption after the exercise using a portable gas analyzer |
| Change in exercise energy expenditure | At pre-exercise, during and up to 15 minutes after the exercise (a single set lasting 30 or 45 seconds) | Total energy expenditure (kcals) during the exercise will be assessed by summing the kcals of the oxidative system, the glycolytic system and the excess post-exercise oxygen consumption. |
| Change in aerobic energy expenditure | At pre-exercise and during the exercise (a single set lasting 30 or 45 seconds) | The contribution of oxidative system in exercise energy expenditure will be assessed by the change in oxygen consumption during the exercise using a portable gas analyzer |
| Change in anaerobic energy expenditure | At pre-exercise and post-exercise (a single set lasting 30 or 45 seconds) | The glycolytic contribution to exercise energy expenditure will be assessed by the change in blood lactate concentration after the exercise |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in blood lactate concentration | At pre-exercise and 4 minutes after the exercise session | Blood lactate concentration will be assessed using a portable automatic analyzer |
| Change in heart rate | At pre-exercise, during and up to 15 minutes after the exercise session. | Heart rate will be assessed using a wearable heart rate monitor |
| Change in rate of perceived exertion | At pre-exercise and post-exercise session. | Perceived exertion will be assessed using the Borg Rating of Perceived Exertion Scale (0-10), with ''0'' indicating ''No Exertion'' and ''10'' indicating ''Maximal Exertion''. |
| Change in respiratory exchange ratio | At pre-exercise, during and up to 15 minutes after the exercise session. | Respiratory exchange ratio will be assessed using a portable gas analyzer. |
