Abstract
The purpose of this study was to investigate the effect of hologram wristbands and placebo on athletic performance measures: acceleration, power, strength, balance and flexibility. Eighteen physically active healthy young adults participated (15 men, 3 women; age: 18.4±0.6 years; weight: 74.5±13.73 kg; height: 177±8.5 cm). Acceleration was measured via the five-metre sprint using a wireless speedtrap; power was measured via the standing long jump; strength was measured via the handgrip dynamometer; balance was measured via the standing stork test with eyes closed; and flexibility was measured via the sit-and-reach test. A double blind, placebo controlled, randomized design with repeated measures was utilized. All participants
undertook four different treatment conditions, consisting of: 1) told wristband/given wristband, 2) told wristband/given placebo, 3) told inert wristband/given wristband, and 4) no wristband, which was the control group. Results were analysed using a one-way analysis of variance with repeated measures. A p value of .05 was used to establish statistical significance. There were no significant differences in acceleration, power, strength, balance or flexibility across any of the four conditions (p>.05). The results indicate that hologram wristbands did not have an immediate effect on athletic performance and no placebo effects were found in any areas of athletic performance.
