Branched Chain Amino Acids (BCAA) merupakan asam amino esensial yang terdiri dari 3 macam asam amino yaitu leusin, isoleusin, dan valin yang berperan dalam protein sintetis dan sistem energi pada saat aktivitas. Kelelahan adalah suatu keadaan ketika seseorang merasa lelah secara fisik atau mental. Berdasarkan ILO (2016), sebanyak 2 juta jiwa setiap tahunnya dan satu pekerja setiap 15 detik meninggal karena kecelakaan yang disebabkan faktor kelelahan. Hasil studi pendahuluan  Juni 2019 di Celebrity Fitness Surakarta dilakukan survey penggunaan BCAA sebanyak 63,5% mengkonsumsi BCAA dan  sebanyak 36,5% diantaranya tidak mengkonsumsi suplemen BCAA. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian suplemen BCAA terhadap kemampuan mencegah terjadinya kelelahan pada pegawai bagian Personal Trainer di Celebrity Fitness Surakarta. Penelitian ini merupakan penelitian eksperimental analitik. Penelitian dilakukan di Celebrity Fitness Surakarta pada bulan Juli sampai Desember 2019. Sampel yang diambil sejumlah 40 orang karyawan dari total  populasi karyawan 63 orang  yang bekerja di departemen PT, FOH, dan MC. Teknik pengambilan sampel menggunakan purposive sampling. Variabel bebas adalah Suplemen BCAA, variabel terikat adalah kelelahan. Analisis data menggunakan t-independent dengan α=5%. Hasil analisis univariat terdiri dari 50% kelompok kontrol (tidak mengkonsumsi suplemen BCAA) dan 50% kelompok perlakuan (mengkonsusmsi suplemen BCAA).  Hasil analisis bivariat menunjukkan nilai pretest antara kelompok kontrol dan perlakuan yaitu p = 0.000 (p< 0,05) yang artinya ada pengaruh signifikan antara pemberian suplemen BCAA dalam kemampuan mencegah terjadinya kelelahan pada pegawai bagian personal trainer. Saran untuk perusahaan agar mengurangi budget target goal conduct setiap bulannya agar pegawai tidak memaksakan diri dengan bekerja atau mengajar lebih dari 8 jam setiap harinya. Untuk pegawai agar tidak mengkonsumsi suplemen BCAA dalam jangka waktu yang sangat lama dikarenakan belum adanya penelitian yang membuktikan efek samping pemakaian jangka panjang dari konsumsi suplemen tersebut.
