PENGARUH PEMBERIAN JUS SEMANGKA KUNING (Citrullus lanatus) TERHADAP KELELAHAN OTOT ANAEROBIK PADA ATLET SEPAKBOLA

Abstract

Background : Muscle fatigue in anaerobic activity occured, when athletes have high intensity activities. The accumulation of lactic acid in muscle and blood could inhibit muscle contraction caused low concentration and performance. Sitrulin in yellow watermelon (Citrullus lanatus) juice can delay muscle fatigue in anaerobic activity. Objective : To know the effect of Yellow Watermelon Juice (Citrullus lanatus) To Anaerobic Muscle Fatigue Index Athletes. Methods : This study used quasi experimental design with a pre-post test design group control design. The fourteen athletes who were randomly divided into control groups and treatment groups. The control group was given a placebo and the treatment group was given a 500 ml watermelon juice with a dose of 1,8gr of sitrulin during seven days. Yellow watermelon (Citrullus lanatus) juice are given 60 minutes before the test done. Anaerobic muscle fatigue in soccer athletes were measured using a RAST (Running-based Anaerobic Sprint Test) by calculating the Muscle Fatigue Index. Data were analyzed by Independent t-test. Results : In this study there was an increase category of muscle fatigue index from good category (0.21-3.31) to very good category (<0.21), although both control and treatment group not significant different statistically (p = 0,532). The mean initial muscle fatigue index of the treatment and control group respectively (0.1157 ± 0.05) and (0.1486 ± 0.65). The mean final muscle fatigue index of the treatment and control group respectively (0.1229 ± 0.04) and (0.1371 ± 0.03). Conclusion : The adduction of yellow watermelon juice (citrullus lanatus) during seven days did not affect the reduction of anaerobic muscle fatigue (p = 0,532).

Faktor – Faktor Yang Berhubungan Dengan Kelelahan Kerja Pada Perawat Di Rumah Sakit Zainuttaqwa Kota Bekasi

“…Hasil penelitian ini sejalan dengan penelitian (Gumelar et al, 2021) yang menemukan sebanyak 80% petugas kesehatan memiliki beban kerja berlebihan, lebih banyak dibandingkan petugas yang tidak memiliki beban kerja berlebih (20%). Penelitian (Maharani et al, 2019) menemukan bahwa perawat yang memiliki beban kerja yang berat/berlebihan lebih banyak (76%) dibandingkan dengan perawat yang memiliki beban kerja yang tidak berlebihan/ringan (24%).…”

“…Daya tahan anaerobik diperlukan dalam aktivitas fisik yang tinggi misalnya senam. Aktivitas fisik senam menghasilkan banyak energi gerakan eksplosif (Maharani et al, 2019). Namun, daya tahan aerobik yang lebih banyak diperlukan untuk recovery.…”

The effect of red watermelon juice on the anaerobic muscle fatigue index during physical exercise

“…Several studies on the effect of citrulline in juice or other beverage treatments on anaerobic fatigue in humans have been conducted. According to research by Maharani et al (2019), giving 500 ml of yellow watermelon juice (Citrullus lanatus) containing 1.8 g of citrulline for 7 days 60 minutes before a test could increase the muscle fatigue index from good to very good (8). According to Hasanah and Fitranti (2015), the anaerobic fatigue value of those given 72 g of red watermelon with 1.17 g of citrulline has a lower value than those who were not given red watermelon (5).…”
