Objectives
Narrative objectives1
Non-invasive brain stimulation techniques (NIBS) are used in rehabilitation settings in hospitals and in sports and training settings. Previous studies have shown that NIBS improves muscle endurance after stimulation compared to before stimulation in sports settings.
However, few studies have investigated muscle strength and power. Therefore, we hypothesized that tDCS and tRNS among NIBS may improve muscle strength and power more
tDCS can modulate motor learning and cognitive abilities by affecting neuroplasticity. tDCS promotes excitability, yet studies in rehabilitation settings have shown that the effects of tDCS vary among individuals. tDCS is a potent stimulator of motor learning and cognitive abilities. tDCS is a potent stimulator of motor learning and cognitive abilities, yet studies in rehabilitation settings have shown that tDCS is not effective in improving muscle strength and power. Despite the fact that tDCS promotes excitability This suggests that individual differences in neuroplasticity may also result in individual differences in the effects of tDCS.
Many studies in the field of sports have been conducted on professional athletes playing at the national level, but no studies have examined the effects of tDCS at the competitive level.
We hypothesize that neuroplasticity, such as motor learning ability, is involved in the differences in competition level, and that differences in the effectiveness of tDCS may also arise. The purpose of this study is to clarify the differences in effectiveness at the level of competition.
