    The claim that the effects of kinesiology tape are different depending on the direction of tape application needs to be clearly ascertained. This study aimed to determine the immediate effects of two forearm kinesiology tape applications on muscle tone, stiffness, and elasticity of young individuals. Thirty-nine participants (15 men and 24 women) were randomized (1:1:1) to: the facilitatory group, receiving kinesiology tape applied from origin to insertion; the inhibitory group, receiving kinesiology tape applied from insertion to origin; or, a control group, without any intervention. The mechanical properties – tone, elasticity, and stiffness – of the forearm muscles were measured with a handheld mechanical impulse-based myotonometric device before and 30 min after the kinesiology tape application. Only the application of kinesiology tape from origin to insertion significantly increased muscle tone [16.6 (2.5) to 17.4 (3.5) Hz, p = 0.036], stiffness [318.3 (52) to 355.0 (87) N/m, p = 0.004], and elasticity [0.98 (0.1) to 1.10 (0.1), p = 0.023]. No changes were observed in both inhibitory kinesiology tape and the control group. In conclusion, kinesiology tape application has different effects depending on the direction of the taping application. The facilitatory tapping increased muscle tone, elasticity, and stiffness.

  • Essential and non-essential elements, and volatile organic compounds for the discrimination of twenty-three sweet cherry cultivars from Fundão, Portugal
    Publication . C.Gonçalves, Ana; Campos, Gonçalo; Pinto, Edgar; Oliveira, Ana Sofia; Almeida, Agostinho; Guedes de Pinho, Paula; Alves, Gilberto; R. Silva, Luís
    The mineral contents and volatile profiles of 23 sweet cherry cultivars were determined. A total of 27 minerals were determined by ICP-MS and flame atomic absorption spectrometry, including 12 essential and 15 non- essential elements. K was the most abundant in all cultivars, while Tl was the one found in the smallest amounts. A total of 66 volatiles were identified using SPME/GC–MS, including 16 aldehydes, 23 alcohols, 6 ketones, 6 esters, 8 monoterpenes, 3 norisoprenoids, 2 hydrocarbons and 2 acids. Benzaldehyde, hexanal, nonanal, benzyl alcohol, (E)-2-hexen-1-ol, 1-hexanol, (Z)-2-hexen-1-ol, 2-ethyl-1-hexanol, linalool, α-terpineol and α-ionone were the major ones. Qualitative and quantitative differences were observed among the cultivars, which influenced nutritional potential and aroma. Cherries from Fund ̃ao region contain high concentrations of phytochemicals and nutritional components. 4-84, Burlat and Celeste might be considered some of the most interesting cultivars, since they are rich in essential minerals and present high diversity in volatiles.
