Brief summary
Exercise-Induced Hypoalgesia (EIH) is a lessening of pain sensitivity in response to an acute bout of exercise. Limited research has examined the effects of expectations on EIH during a dynamic resistance training during different intensities. Therefore, the purpose of this study is to examine the effects of positive and negative expectations on EIH.
Detailed description
Individuals who meet the eligibility criteria and consent to participate will attend one testing session that is approximately one hour. Baseline Pressure Pain Threshold will be measured followed by random assignment to one of four study arms.
Interventions
OTHERPositive Expectations Instructional Set
Participants randomly assigned to this instructional set will be told, You will be completing an intervention known to be effective for some people with shoulder pain. We expect this will make you less sensitive to the pressure applied to your shoulder and thigh and you will require more pressure than what was previously necessary to experience pain.
OTHERNegative Expectations Instructional Set
Participants randomly assigned to this instructional set will be told, You will be completing an intervention which is not effective for some people with shoulder pain. We expect this will make you more sensitive to the pressure applied to your shoulder and thigh and you will require less pressure than what was previously necessary to experience pain.
