Generally, the aim of this research to know the comparison of caffeine drinks through the result of reaction time after consumption coffee, green tea, and energy drink by the same amount of caffeine. The way to gather the data is using purposive sampling, the population that chosen by researcher is 10 respondents college students of Ilmu Keolahragaan batch 2016. For data analysis, using SPSS 21 program for windows and Statistical calculation that used is One-Way ANOVA continues with Post Hoc Tukey. The average of result from time reaction on Speed Anticipation Reaction is 1.263 (placebo), 1,257 (green tea), 1.271 (energy drink), and 1.358 (black coffee). For Body Reaction Time Test (visual) shows the average around 1.239 (placebo), 0.245 (green tea), 0.257 (green tea), and 0.244 (black coffee). While on Whole Body Reaction Time Test (auditory) shows the average0.239 (placebo), 0.239 (green tea), 0.274 (energy drink), and 0.263 (black coffee). The signification value from three time reaction test are (Speed Anticipation Reaction Sig. 0.706 > 0.05, Whole Body Reaction (visual) Sig. 0.877 > 0.05, and Whole Body Reaction (auditory) Sig. 0.348 > 0.05) all of the result above 0.05. Hence, it can be conclude there is no significantly difference through time reaction result after consumption kind of caffeine drinks with the same concentration.

The purpose of this study is to determine the effect of an acute local vibration exercise on the visual reaction time of a fencer’s upper body extremities. Twenty-six male fencers between the ages of 15 and 23 (mean age, 17.38 ± 2.13 years, height: 173.6±9.1 cm, body mass: 70.2 ±14.1 kg) volunteered for this study. The reaction time test was applied before and after the vibration exercise (applied for 30 seconds in 27 Hz with a 2-mm amplitude). After 25 min. standard warming up, fencers were informed about the test, and three repeated reaction tests were performed to provide familiarization. The fencers started the reaction test in the standard fencing guard position. According to five signals coming at two to five second intervals from the target monitor, the fencers made touché by bending (attacking). The reaction time test had five trials. The average reaction time values pre-vibration, and post-vibration were compared. The visual reaction time measured pre-vibration were significantly longer than those measured post-vibration (p<0.001). Acute local vibration exercise applied to fencers shortened the visual reaction time. Given the fact that vibration can improve RT, the use of vibration in training has the potential to provide an advantage to fencers.

Karate merupakan olahraga prestasi yang sangat terkenal, terbagi oleh dua kelas kata dan kumite. Whole body reaction time test dan anticipation reaction time adalah kebutuhan dasar reaksi yang harus dimiliki seorang atlet karate, peneliti ingin membuktikan whole body reaction dan anticipation reaction time atlet kumite lebih baik dari atlet kata tersebut benar adanya atau tidak, dikarenakan berpengaruh terhadap program latihan yang diberikan kepada atlet. Tujuan penelitian ini untuk mengetahui perbandingan whole body reaction time dan anticipation reaction time atlet kumite lebih baik dari atlet kata. Metode penelitian yang digunakan adalah deskriptif komparatif. Sample penelitian berjumlah 10 atlet karate kata dan 10 atlet karate kumite dengan teknik pengambilan sampling menggunakan teknik sampling jenuh. Hasil penelitian ini dianalisis dengan bantuan spss ver.21 menunjukkan data whole body reaction time nilai f = 4,508 dan sig. 0,059 > 0,05 maka H0 diterima dan dapat disimpulkan tidak terdapat perbedaan hasil kecepatan whole body reaction time test dengan atlet kata dan kumite cabang olahraga karate, sedangkan data anticipation reaction time nilai f = 1,787 dan sig. 0,198 > 0,05 maka H0 diterima dan dapat disimpulkan tidak terdapat perbedaan hasil kecepatan anticipation reaction time test dengan atlet kata dan kumite cabang olahraga karate.

Reaction Time Test

Three groups of 24 subjects were exposed to a 1000–Hz tone or broad band noise in a sound chamber. During the exposures subjects were engaged in an easy reaction time test or a difficult grammatical reasoning test. For each exposure and work subjects adjusted the noise to a tolerance level defined by its interference with task performance. During the simple reaction-time task significantly higher sound-pressure levels were accepted than during the reasoning test. At the tonal exposure, much lower levels were accepted than during the exposure to broad-band noise. For continuous sound exposures much higher levels were accepted than for noncontinuous exposures. For tonal exposures the difference was approximately 5 dB, for the broad-band exposures approximately 9 dB. In a separate study the effects of the noncontinuity of the noise and pauses were analysed. The raised annoying effect of the noncontinuous noise was not more affected by the noncontinuity of the noise periods than by the noncontinuity of the pauses. The results imply that the annoying reactions to the sound will be increased for repetitive noise and that the reaction is highly influenced by the over-all noncontinuity of the exposure.

Background: Every activity requires a certain amount of concentration and no effective action may be performed without deep concentration. Businessman or artists or students in school must know the art of focusing all powers of attention on a single point in order to succeed in their respective vocation.Methods: We wanted to find the best technique to increase the concentration scientifically. We thus, endeavored to study and compare the reaction times in maneuvers of anuloma viloma pranayama, kapalbhatti pranayama, gayatri chanting and exercise. Reaction time test was taken online before anuloma viloma pranayama, kapalbhatti pranayama, gayatri chanting and exercise and compared after.Results: Reaction times decreased significantly and was least during gayatri mantra. Concentration as seen by a decrease in visual reaction time denotes first a withdrawal of attention from objects of distraction and then focusing all attention upon one thing at a time. Just 30 minutes of physical activity each day offers substantial benefits to your health.Conclusions: Pranayama or devotional music chanting also decreases fatigue keeps the mind alert, and active.Bangladesh Journal of Medical Science Vol.15(4) 2016 p.596-600
