Exercise-Induced Hypoalgesia Differences Between Upper and Lower Limbs Resistance Training Interventions

PPT is tested on the muscle belly of the quadriceps on the dominant side, at half of the distance between the anterior-superior iliac spine and the superior pole of the patella, and on the muscle belly of the brachial biceps on the dominant side, at a point one-fourth of the distance from the elbow crease to the lateral border of the acromion. The region to be pressed is marked with a pen. The patient is instructed to report the first appearance of the sensation of "discomfort". An ascending ramp of 0.5 kg/cm/s is applied, at the rhythm of a metronome. The instrument measures 0 to 25 kg, with a higher score interpreted as a hypoalgesia response. The measurement is started on the quadriceps and alternated with the biceps until 3 measurements of each region are obtained. Each measurement in the same region is obtained after 30 seconds of rest. This protocol has demonstrated high inter-observer reliability measuring healthy subjects (ICC = 0.91).

7-item questionnaire on the level of physical activity at different intensities (high, moderate, and low) and hours sitting.

A higher score means higher weekly physical activity

7-item questionnaire that assesses an individual's readiness to engage in physical activity based on whether any known contraindications have been ruled out by the participant.

If all the questions are negative, the participant can safely engage in a physical activity.

10-item questionnaire that allows for the evaluation of the participant's current level of fatigue. This instrument measures 10 to 50 points.

A higher score means higher fatigue.

RPE Borg CR-10 is used to measure how hard your body works during physical activity. It runs from 0 - 10, using numbers to rate how much effort an activity takes. Higher scores indicate a higher perception of effort.
