Kafeinin, aerobik dayanıklılık performansı üzerine etkisi bilinmektedir fakat anaerobik güç üzerine etkisini inceleyen çok az çalışma mevcuttur ve sonuçlar birbiri ile farklılık göstermektedir. Ayrıca, son yıllarda kafeinli kahve ve toz kafeinin aerobik ve kassal kuvvet performansları üzerine etkilerinde farklılık olmadığını gösteren çalışmalar mevcuttur. Bu çalışmanın amacı, düşük doz kafeinli kahvenin fiziksel olarak aktif erkeklerde 30 saniyelik wingate anaerobik test (Want) performansına etkisinin incelenmesidir. Araştırmaya 11 erkek (yaş: 24,90 ± 3,61 yıl, boy: 177,36 ± 7,55 cm, vücut ağırlığı: 76,35 ± 14,70 kg, vücut yağ yüzdesi: 19,44 ± 4,20) gönüllü olarak katılmıştır. Vücut kompozisyonu ölçümü ve alışma test gününün ardından, randomize, çapraz geçişli, karşıt dengeli ve tek kör çalışma dizaynı ile katılımcılar test başlamadan 60 dakika önce 0,093 gr/kg kafeinli kahve (KAF) veya 0,093 gr/kg kafeinsiz kahve (PLA) alarak veya kahve almadan (KON) toplamda 3 Want testine katılmışlardır. Test öncesinde farklı zaman noktalarında dinlenim kalp atım hızı (KAH) ölçülmüş, Want performans parametreleri olarak zirve güç (ZG) ve ortalama güç (OG) saptanmış ve testten hemen sonra, 50 Watta 5 dakika aktif ve 5 dakika pasif toparlanma periyotlarından sonra KAH, algılanan zorluk derecesi (RPE), ve kas ağrısı (KA) ölçümleri alınmıştır. Verilerin analizinde ZG ve OG parametreleri için tekrarlayan ölçümlerde tek yönlü varyans analizi kullanılmış, RPE, KA ve KAH verilerinin denemeler arası farklarını incelemek için ise tekrarlayan ölçümlerde iki yönlü varyans analizi kullanılmıştır. Sonuç olarak denemeler arası OG ve ZG değerlerinde anlamlı bir fark bulunamamıştır (p>0,05). Ayrıca test protokolü boyunca farklı zaman noktalarında ölçülen RPE, KA ve KAH değerleri arasında da denemeler arası anlamlı bir fark bulunamamıştır (p>0,05). Kafeinli kahvenin fiziksel aktif erkeklerde anaerobik güce bir etkisi olmadığı düşünülmektedir

EFFECT OF LOW DOSE CAFFEINATED COFFEE ON ANAEROBIC POWER IN PHYSICALLY ACTIVE MALES

Öz

It is well known that effects of caffeine on aerobic endurance but there isn’t many research that investigating the effect on anaerobic power and the results vary. Furthermore, there are researches that demonstrating caffeinated coffee and anhydrous caffeine has same effects on aerobic and muscular strength performance. The purpose of this study was to investigating the effect of low dose caffeineated coffee on 30 seconds wingate anaerobic test (Want) performance in physically active males. 11 male (age: 24,90 ± 3,61, height; 177,36 ± 7,55 cm, weight: 76,35 ± 14,70 kg; body fat percentage:19,44 ± 4,20) volunteered to participate in this investigation. Following measurement of body composition and familirization, participants totally take part in 3 Want tests while 60 minutes before each Want test, participants ingested 0,093 gr/kg caffeinated coffee (KAF) or 0,093 gr/kg decaffeinated coffee (PLA) or no coffee (KON) with randomized, counter balanced and crossover reseach design. At different time points before test, Heart rate (KAH) was measured, as Want performance parameters peak power (ZG) and mean power (OG) was determined and, KAH, rate of perceived exertion (RPE) and muscle pain(KA) was measured immediately after test and after 5 minutes 50 Watt active and passive recovery periods. To analyse ZG and OG parameters, repeated measure one-way Anova was used, to anaylse RPE, KA and KAH datas, repeated meausure two-way Anova was used. In conclusion, there aren’t significant differences between trials for OG and ZG (p>0,05). Further, it wasn’t found any significant difference between trials for RPE, KA and KAH which was meausured at different time points throughout test protocol (p>0,05). It is believed that there is no effect of caffeinated coffee on anaerobic power in physically active males
