Age
18 Years to 30 Years

Inclusion criteria

Inclusion criteria: Healthy volunteers; female; aged between 18 and 30; with motor preference for the right upper limb

Exclusion criteria

Exclusion criteria: Severe pain; discomfort during testing; inability to perform the experimental protocol as instructed; voluntary withdrawal; participants who fail to achieve at least 70% of maximum voluntary isometric contraction (MVIC) in the post-test measurement

Design outcomes

Primary

MeasureTime frame
To evaluate the influence of fatigue induced by a series of palmar grip repetitions on the involuntary activation of synergistic and contralateral muscles (motor overflow) during an isometric flexion activity of the index finger in healthy participants

Secondary

MeasureTime frame
To examine the relationship between motor overflow and muscle fatigue after a series of palmar grip repetitions. To analyze force generation during an isometric flexion activity of the index finger at 70% of maximum voluntary isometric contraction (MVIC), considering the influence of laterality and motor preference in healthy women
