简要总结
This randomized controlled trial with healthy subjects aims to compare exercise-induced hypoalgesia among three groups: one utilizing a lower limb resistance training intervention, another using an upper limb resistance training, and a control group. The exercise protocol involves 3 sets of 5 repetitions of resistance exercises (brachial biceps curl and leg extensions). Exercise-induced hypoalgesia will be assessed by measuring pressure pain thresholds in the thigh and elbow, comparing exercise interventions with the control group. Additionally, a secondary objective is to compare the lower limb and upper limb resistance training groups in terms of their effects on pressure pain thresholds in the thigh and elbow. Thus, the study anticipates observing differences in local and distal hypoalgesia based on the trained region.

结局指标
主要结局
Pain pressure threshold (PPT) on dominant quadriceps and dominant brachial biceps
时间窗: before, immediately after intervention, and 30 minutes after intervention.
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).
