<p></p><p>There was a nutritional issue in the training camp of Central Java BPPLOP (Balai Pemusatan Pendidikan Latihan Olahraga Pelajar/Student Sport Education and Training Center). The year 2017 data showed that 8% of athletes experienced nutritional deficiency and 10% of athletes experienced nutritional excess. This research aimed to evaluate the effectiveness of a personalized nutrition program toward percentage of energy consumption level (%ECL), body mass index (BMI), and body fat percentage (%BF). This research utilized one-group pretest-posttest design. The subjects were 59 martial arts athletes in Central Java BPPLOP. The personalized nutrition program intervention lasted a month and was encouraged by a smartphone application called Nutriatlet. The statistical test was a paired sample t test. The research concluded that mean %ECL improved significantly after intervention, from 63.37 ± 8.57 to 82.91 ± 6.31 (p < 0.001). The BF percentage also improved from 14.36 ± 6.19 to 13.40 ± 5.88 (p < 0.001). Mean BMI was not significantly different after intervention, from 21.95 ± 2.51 to 22.02 ± 2.25 (p = 0.524). We concluded that Nutriatlet usage to evaluate a personalized nutrition program could improve the energy consumption level and body fat percentage while maintaining body mass index.</p>
