The aim of this study is to understand the relationship between perceived effort and physiological and kinematic variables caused by isometric activity of the upper limbs, as well as its relationship with socio-demographic characteristics, level of activity and quality of life.

| Measure | Description | Time Frame |
|---|---|---|
| Change from Baseline in perceived effort on the Borg category-ratio 10-point scale (CR 10) | The perceived effort will be measured with Borg CR 10 scale. Possible scores range from 0 (no exertion at all) to 10 (extremely strong). | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in heart rate | Heart rate (heart beatings per minute) measured before and during activity to track cardiovascular changes during activity. | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in respiratory rate | Respiratory rate (respiratory cycles per minute) measured before and during activity to track changes in respiratory function during activity. | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in heart rate variability (HRV) | Interval (in milliseconds) between consecutive heartbeats measured before and during activity to track changes in autonomic function during activity. | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in electrodermal activity (EDA) | Electrical conductance (in microsiemens -µS) between two points of the hand over time measured before and during activity to track changes in autonomic function during activity. | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in muscle action potential amplitude through surface electromyography (sEMG) | Muscle action potential amplitude (in millivolts - ms) in surface electromyographic signal measured before and during activity to track muscular fatigue signs. |
| Measure | Description | Time Frame |
|---|---|---|
| Health Status | Health Status will be measured with Medical Outcomes Study (MOS) Short Form Health Survey 36 Item version 2 which measure health status of populations and individuals. Possible scores range from 0 0 (worst health status) to 100 (best health status). | Before isometric activity |

| Change from Baseline in muscle action potential frequency through surface electromyography (sEMG) | Muscle action potential frequency (in hertz - Hz) of surface electromyographic signal measured before and during activity to track muscular fatigue signs. | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in respiratory pattern through inertial motion units (IMU) from baseline and during activity | Angular range of motion (in degrees) of rib cage and abdominal wall during upper limb activity measured before and during activity to track changes in respiratory pattern during activity | From baseline to end of activity, up to 15 minutes |
| Change from Baseline in upper limb motion angular acceleration through inertial motion units (IMU) system | Angular acceleration (in m/s^2) of the arm measured before and during activity to track small movements of upper limb during isometric activity | From baseline to end of activity, up to 15 minutes |
Physical activity level will be measured using European Prospective Investigation into Cancer and Nutrition Physical Activity Questionnaire (EPIC-PAQ) that allows to estimate energy expenditure through self-report assessment of the intensity and average duration (per day, week and month) of physical activity performed by the participants in three distinct dimensions (professional, domestic and leisure). Participants are classified as ACTIVE if they perform: at least 150 minutes per week of moderate physical activity; OR at least 75 minutes per week of vigorous physical activity; OR at least 150 minutes per week of a combination of moderate-intensity activity. If they don't present any of the conditions described, they will be categorized as SEDENTARY. |
