Type effect of inhibitory KT tape on measured vs. perceived maximal grip strength

Elevated arousal following acute ammonia inhalation is not associated with increased neuromuscular performance

“…However, peak power would not be enhanced by such an increase in oxidative metabolism. Unlike the present study, where participants were well rested prior to performing CMJ, participants in the aforementioned study by Secrest et al (2015) were required to reach fatigue before the effects of AI use on anaerobic power was assessed (Secrest et al, 2015). Similar to RFD; AI use may only produce substantive effects on power performance when peak power has previously been depleted by individuals reaching a state of fatigue, such as may be experienced in the latter stages of sporting competition.…”

“…The ICC of all trials was calculated as 0.97. Following assessment of all functional measures, participants self-rated their perceived performance level using a 200 mm VAS which ranged from "worst performance" at the extreme left to "best possible performance" at the extreme right (MacPhail et al, 2018). The two ends of the VAS were anchored by perpendicular lines, but there were no increments between the end markers.…”

“…AIs are a common example of a stimulant‐based ergogenic aid used within competitive sport; yet, despite their popularity, there has been little research into their effect on sporting performance. Greater anaerobic power has been observed with AI use in a fatigued state (Secrest, Jones, & Faries, 2015), but they have been shown not to impact lower limb or full body static strength (Bartolomei et al, 2018; Perry, Pritchard, & Barnes, 2016), dynamic strength (Richmond, Potts, & Sherman, 2014; Vigil, Sabatini, Hill, Swain, & David Branch, 2018), or number of repetitions to fatigue (Richmond et al, 2014). However, no previous study has assessed the influence of AIs on isolated upper body strength only.…”

“…Furthermore, improved cerebral delivery of oxygenated blood and CNS excitation, result in increased consciousness and enhanced sympathetic activity. In terms of an advantageous effect for sporting performance, these responses could potentially elicit cognitive enhancement and increase central drive (Secrest et al, 2015). Equivocal findings of an effect of AIs on RFD (Bartolomei et al, 2018; Perry et al, 2016) compel further investigation; if there is, as suggested, an increase in central drive associated with AI use, elevated RFD would be expected, accompanied by a shortening of electromechanical delay (EMD), and therefore, overall reaction time (RT).…”

Kinesiology Tape: A Descriptive Survey of Healthcare Professionals in the United States

“…No tension ceived maximum strength for the forearm muscles, [61][62][63] quadriceps, [64][65][66][67] and calf muscles. 67 Researchers have also reported no therapeutic differences between KT, sham tape, and control group for individuals with lateral epicondylitis [68][69][70] and chronic low back pain.…”
