Influence of Fast and Slow Imagined Muscle Contractions on Muscle Function or Central Nervous System Properties

Description

The goal of this randomized clinical trial is to learn if imagining fast or slow muscle contractions causes different responses for nervous system excitability and muscle function in young, healthy males and females in. The main questions are: Does imagining fast muscle contractions cause greater nervous system excitability compared to imagining slow muscle contractions? Does imagining fast muscle contractions increase muscle function compared to imagining slow muscle contractions? A control condition (rest) will be compared with two intervention conditions: imagining fast and imagining slow conditions, to determine if the fast and slow increase outcomes more than control and if fast has the greatest response. Participants will: * Attend 4 laboratory visits * Perform 50 imagined contractions fast or slow, but with no physical movement * Physical muscle contractions and non-invasive brain stimulation would be completed before and after each condition.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Be between the ages of 18 - 30
  • * Healthy (no medical conditions)
  • * If female, must be taking the same monophasic oral contraceptive for the past 6 months
  • * Have a body mass index between 18.5 - 30 kg/m2
  • * Have not performed structured cardiovascular or resistance exercise in past 3 years
  • * Be right-handed
