About

This study investigates the evolution of sensory, motor and tissue variables following exercise-induced pain in wrist extensor muscles in healthy subjects.

Full description

The aim of this study is to determine how is the normalization process of sensory (pressure pain thresholds, subjective pain sensation, self-recovery perception), motor (maximal isometric strength, active range of motion, manual dexterity) and tissue (myotonometer) variables after an experimental pain model in the extensor forearms muscles, by delayed onset muscle soreness after an eccentric exercise in healthy subjects. This way will be possible to establish 1) if there are differences in the time of normalization for each variable; 2) if there is a correlation between each variable and self-recovery perception.

Seven assessment sessions are performed in a 14-days period. Day 0 (baseline assessment 1), Day 7 (baseline assessment 2, pre exercise), Day 7 (post exercise), Day 8 (24-hours post exercise), Day 9 (48-hours post exercise), Day 10 (72-hours post exercise), Day 14 (1-week post exercise).
