What is The Most Effective Time after Caffeine Mouth Rinse Method for Reaction Speed?

Abstract

There are a lot of research examining the effect of caffeine (CAF) consumption in various doses on reaction speed (RS), which is an important component of sportive performance. Studies examining the effect of CAF mouth rinse on the RS are limited and the most effective time after the method has not been researched. The aim of this study is to determine the most effective time after the CAF mouth rinse on the RS. Healthy and trained 31 athletes who voluntarily participated in this repetitive and single-blind designed study performed the RS test in control (without rinsing), placebo (water) and CAF mouth rinse sessions. The RS test was repeated 0-5-10-15-20-25. minutes after the CAF was rinsed in the mouth. Moreover, the physical activity (FA) habits, daily CAF consumption routines, morning-evening characteristics, and sleepiness levels were evaluated with the questionnaires applied to the participants, and the effects of these characteristics on the RS test outcomes were investigated. As a result of Variance Analysis in repeated measurements, RS measured after 10 seconds of rinsing 600 mg (2.4%) of CAF added to 25 ml of water was found to be significantly better than the control and placebo sessions, as well as the RS measured at 10-15-20. minutes from the 5 and 25 minutes. As a result of Two-Way Variance Analysis in repeated measurements, Morning-evening type, FA activity, and daily CAF consumption levels were found to be effective on RT test results. The obtained results suggest that athletes who want to increase the RS can rinse the 2.4% CAF-containing solution in the mouth and may show better RS performance especially between 10-20. minutes after rinsing.

Reaksiyon Hızı için Kafein Ağızda Çalkalama Yöntemi Sonrası En Etkili Süre Nedir?

Abstract

Çeşitli dozlarda kafein (KAF) tüketiminin, sportif performansın önemli bir bileşeni olan reaksiyon hızına (RH) etkisini inceleyen çok sayıda çalışma olsa da etki mekanizmasının farklı olduğu iddia edilen KAF ağızda çalkalama yönteminin RH’ya etkisini inceleyen çalışmalar sınırlı sayıdadır ve uygulama sonrası en etkili süre incelenmemiştir. Bu çalışmada amaç, RH üzerinde KAF ağızda çalkalama sonrası en etkili sürenin belirlenmesidir. Tekrarlı ve tek kör dizaynında planlanan bu çalışmaya gönüllü olarak katılan 31 sağlıklı ve antrene sporcu RH testini kontrol (çalkalama yapılmadan), plasebo (su) ve KAF ağızda çalkalama seanslarında gerçekleştirmiş, KAF ağızda çalkalandıktan 0-5-10-15-20-25 dakika sonra RH testi tekrarlanmıştır. Ayrıca katılımcılar uygulanan anketler ile fiziksel aktivite (FA) seviyeleri, günlük KAF tüketim miktarları, sabahçıl-akşamcıl olma özellikleri ile uykululuk durumları değerlendirilmiş, bu özelliklerin RH test sonuçlarına etkisi araştırılmıştır. Tekrarlayan ölçümlerde Varyans Analizi sonucunda, 25 ml suya eklenen 600 mg (%2,4) KAF’ın 10 sn ağızda çalkalanması sonrası ölçülen RH, kontrol ve plasebo seanslarından, ayrıca 10-15-20. dakikalarda ölçülen RH, 5 ve 25. dakikalardan anlamlı olarak iyi bulunmuştur. Tekrarlı ölçümlerde iki yönlü Varyans Analizi sonucunda, Sabahçıl-akşamcıl tip, FA aktivite ve günlük KAF tüketim düzeyleri RH test sonuçları üzerinde etkili olmuştur. Elde edilen sonuçlar reaksiyon hızını artırmak isteyen sporcuların %2,4 KAF içeren solüsyonu ağızda çalkalama yöntemini uygulayabileceklerini ve özellikle çalkalamadan sonraki 10-20. dakikalar arasında daha iyi RH performansı gösterebileceklerini düşündürmektedir.
