The Perceived Tightness Scale Does Not Provide Reliable Estimates Of Blood Flow Restriction Pressure., Zachary W Bell, Scott J. Dankel, Robert W Spitz, Raksha N Chatakondi, Takashi Abe, Jeremy P Loenneke

Faculty Scholarship for the College of Science & Mathematics

CONTEXT: The perceived tightness scale is suggested to be an effective method for setting subocclusive pressures with practical blood flow restriction. However, the reliability of this scale is unknown and is important as the reliability will ultimately dictate the usefulness of this method.

OBJECTIVE: To determine the reliability of the perceived tightness scale and investigate if the reliability differs by sex.

DESIGN: Within-participant, repeated-measures.

SETTING: University laboratory.

PARTICIPANTS: Twenty-four participants (12 men and 12 women) were tested over 3 days.

MAIN OUTCOME MEASURES: Arterial occlusion pressure (AOP) and the pressure at which the participants rated a 7 out of 10 …

Transcranial Direct Current Stimulation Of Motor Cortex Enhances Running Performance., Seung-Bo Park, Dong Jun Sung, Bokyung Kim, Sojung Kim, Joung-Kyue Han

Transcranial direct current stimulation (tDCS) is a technique used to modulate neuronal excitability through non-invasive brain stimulation that can enhance exercise performance. We hypothesize that tDCS would improve submaximal running time to exhaustion (TTE) and delay the increase in the rating of perceived exertion (RPE) over time. We also hypothesize that tDCS would not lead to difference in cardiorespiratory responses. We employed a randomized, single-blinded, and counterbalanced design in which 10 trained men participated. After receiving either 20 min of 1.98 mA anodal tDCS applied over the primary motor cortex (M1) or sham-operated control on separate days, participants completed a …
