Rekreasyonel Sporcularda Bal Bazlı Karbonhidrat İçeceğinin Aralıklı Egzersiz Performansı ve Kalp Atım Hızı Toparlanması Üzerine Akut Etkileri

Öz

Beslenme stratejileri, egzersiz performansını ve toparlanmayı geliştirme potansiyeli nedeniyle geniş şekilde araştırılmıştır. Karbonhidrat temelli içeceklerin egzersiz sırasında enerji kullanılabilirliğini artırdığı ve yorgunluğu geciktirdiği bilinmektedir. Bu çalışma, rekreatif olarak aktif bireylerde bal bazlı bir karbonhidrat içeceğinin aralıklı egzersiz performansı ve kalp atım hızı toparlanması üzerindeki akut etkilerini incelemeyi amaçlamıştır. Toplam 21 rekreatif olarak aktif katılımcı (16 erkek ve 5 kadın; yaş ortalaması: 19.5±1.1 yıl) denek-içi tekrarlı ölçümler tasarımında çalışmaya dahil edilmiştir. Katılımcılar, kontrol ve suplementasyon koşullarını iki haftalık yıkama periyodu ile ayrılmış şekilde Yo-Yo Aralıklı Toparlanma Testi Seviye 1’i tamamlamıştır. Deney koşulunda katılımcılar, testten 30 dakika önce 15 g bal (60 kcal) içeren bir içecek tüketmiştir. Toplam kat edilen mesafe, tahmini VO₂maks ve algılanan efor derecesi kaydedilmiş; kalp atım hızı ise egzersiz öncesi, egzersiz hemen sonrası ve toparlanmanın 1. ve 2. dakikalarında ölçülmüştür. Veriler eşleştirilmiş t-testi kullanılarak analiz edilmiştir. Sonuçlar, bal alımı sonrasında egzersiz bitimindeki kalp atım hızında (p=0.038) ve 1. dakika toparlanma kalp atım hızında (p=0.007) anlamlı azalma olduğunu, buna karşın egzersiz öncesi kalp atım hızı, 2. dakika toparlanma kalp atım hızı, toplam kat edilen mesafe, tahmini VO₂maks ve algılanan efor derecesi (p>0.05) değişkenlerinde anlamlı fark olmadığını göstermiştir. Bu bulgular, bal bazlı bir karbonhidrat içeceğinin akut tüketiminin egzersiz sonrası erken dönem kalp atım hızı toparlanmasını iyileştirdiğini, ancak aralıklı egzersiz performansı ve algılanan efor derecesi üzerinde etkili olmadığını göstermektedir. Bu durum, görece düşük dozda doğal karbonhidrat alımının bile rekreatif olarak aktif bireylerde egzersiz sonrası kardiyovasküler toparlanmayı olumlu yönde etkileyebileceğini düşündürmektedir.

Acute Effects of Honey-Based Carbohydrate Beverage on Intermittent Exercise Performance and Heart Rate Recovery in Recreational Athletes

Öz

Nutritional strategies that enhance exercise performance and recovery have been widely investigated. Carbohydrate-based beverages are known to improve energy availability and delay fatigue during exercise. This study aimed to examine the acute effects of a honey-based carbohydrate beverage on intermittent exercise performance and heart rate recovery in recreationally active individuals. A total of 21 recreationally active participants (16 males and 5 females; mean age: 19.5±1.1 years) participated in a within-subject repeated-measures design. Participants completed the Yo-Yo Intermittent Recovery Test Level 1 under control and supplementation conditions separated by a two-week washout period. In the experimental condition, participants consumed a beverage containing 15 g of honey (60 kcal) 30 minutes prior to testing. Total distance covered, estimated VO₂max, and rate of perceived exertion were recorded, and heart rate was assessed pre-exercise, immediately post-exercise, and at 1 and 2 minutes of recovery. Data were analyzed using paired-sample t-tests. Results showed a significant reduction in end-exercise heart rate (p=0.038) and 1-minute post-exercise heart rate (p=0.007) following honey ingestion, whereas no significant differences were observed for pre-exercise heart rate, 2-minute post-exercise heart rate, total distance covered, estimated VO₂max, or rate of perceived exertion (p > 0.05). These findings indicate that acute ingestion of a honey-based carbohydrate beverage was associated with lower end-exercise and 1-minute post-exercise heart rate values, suggesting improved early-phase heart rate recovery, without affecting intermittent exercise performance or rate of perceived exertion. This suggests that even a relatively low dose of natural carbohydrate may positively influence post-exercise cardiovascular recovery in recreationally active individuals.
