Abstract

Background: The success of soccer athletes is influenced by physical, mental, and genetic factors, with nutritional status significantly affects youth soccer performance in Indonesia by 69.8%. Body composition and somatotype are critical components of nutritional status. Biochemical indicators such as creatine kinase (CK) and vitamin D levels provide insights into the impact of training and diet on athletes. Objectives: To determine the effect of nutritional interventions on improving the intake and body composition of athletes characterized by the value of creatinine kinase levels and vitamin D levels of athletes and an increase in VO2 Max values as performance indicators. Methods: This experimental study used a pre-post control trial design involving 39 subjects who were divided into treatment (20 athletes) and control (19 athletes) groups for one month. The treatment group received nutrition education (classroom, individual, and nutrition assistance) and vitamin D supplementation of 800 IU per day, while the control group was only monitored. The exercise was adjusted to the coach's program. Results: Energy, protein, and carbohydrate intakes were deficient among athletes, although fat intake was adequate. CK levels were within normal limits. All athletes in the control group exhibited vitamin D deficiency, compared to 90% in the intervention group, despite supplementation showing modest improvement. Conclusions: Vitamin D supplementation has a significant effect on increasing blood vitamin D levels. This study reinforces the importance of education and supplementation-based nutrition interventions to improve the nutritional status and performance of soccer athletes.

Abstract

Background: Non-Communicable diseases (NCDs) are increasing among Indonesia’s productive and pre-elderly populations. Cardiometabolic risk factors such as obesity, dyslipidemia, hypertension, and hyperglycemia substantially contribute to this burden, accounting for approximately 70-75% of all deaths. The workplace offers a strategic location for promotional and preventive interventions through Worksite Health and Wellness Programs (WHWPs). Objectives: To assess the effectiveness of WHWPs in improving body composition, fitness, and cardiometabolic risk factors among employees. Methods: A quasi-experimental design with a one-group pre–post test was applied to 35 employees aged 30–60 years with BMI ≥25 kg/m². The 12-week intervention included nutrition education and combined cardio and strength training. The variables measured included anthropometry, body composition, fitness, blood pressure, blood glucose, total cholesterol, dietary intake, and nutritional knowledge. Data were analyzed using paired t-tests, repeated measures ANOVA, and Friedman’s test. Results: Significant improvements were observed in body composition, with reductions in body fat percentage (from 32.81 to 31.46%; p-value=0.005), subcutaneous fat (from 28.67 to 26.84; p-value=0.042), and an increase in skeletal muscle mass (from 25.70 to 26.45; p-value=0.015). Fitness improved significantly (from 32.39 to 35.80; p-value<0.001). Total cholesterol decreased (from 199.94 to 177.40 mg/dL; p-value=0.003), while blood glucose and blood pressure did not change significantly. Natrium intake decreased (from 3209 to 1740 mg; p-value=0.013) and nutrition knowledge scores increased (from 51.65 to 57.33; p-value=0.006). Conclusions: WHWPs effectively improved body composition and fitness and reduced cardiometabolic risk factors among employees.
