Abstract Background: The intake of citrulline (CIT) and leucine (LEU) can stimulate protein synthesis. However, the efficacy of the combined intervention of CIT and LEU intake with exercise on body composition and physical activity (PA) remains unclear. This study aimed to investigate the combined effect of CIT and LEU intake and weight-bearing exercises (WBE) and square stepping exercise (SSE) for 20 weeks on body composition, PA, and amino acid concentration in older women with low body mass index (BMI) (16 to 21 kg/m 2 ). Methods: A total of 23 participants practiced WBE and SSE once a week for 75 minutes and were administered supplement (Ex + CIT·LEU group: CIT 0.8 g and LEU 1.6 g; Ex + Placebo group: 3.5 g carbohydrate) twice a day for 20 weeks. Body composition was measured using dual-energy X-ray absorptiometry. PA, including leisure-time, household, and occupational PA, was assessed using the Physical Activity Scale for the Elderly. Amino acid concentrations in the blood were analyzed by high-performance liquid chromatography.Results: Significant interactions were observed in the body weight, BMI, lean mass, body mass, household and total PA, tyrosine, and phenylalanine. The within-group analysis showed that tyrosine of post-intervention measurement (Post) significantly in both groups ( p < 0.05). Body weight, BMI, lean mass, body mass, household PA, total PA, and phenylalanine of Post increased significantly in the Ex + CIT·LEU group ( p < 0.05). Additionally, significant positive correlations were observed between the intake rate of supplements and bone mass ( r = 0.80) and between the practice rate of WBE at home and bone mineral density ( r = 0.66) in the Ex + CIT·LEU group. Conclusion: Our findings suggest that the intake of CIT and LEU, with the practice of WBE and SSE, could improve body weight, muscle mass, bone mass, and PA in older women with low BMI, which may prevent sarcopenia and frailty.Trial registration: UMIN000022385.

The combined intake of citrulline (CIT) and leucine (LEU) can stimulate protein synthesis. Therefore, this study aimed to investigate the effect of combined intake of CIT and LEU accompanied by exercise for 20 weeks on body composition, physical activity (PA), and amino acid concentrations in older Japanese women with low body mass index (BMI) (16 to 21 kg/m2) using a randomized, double-blind, placebo-controlled design. The supplement was administered twice a day for 20 weeks (Ex (exercise) + CIT·LEU group, n = 10: mainly 0.8 g CIT and 1.6 g LEU; Ex + Placebo group, n = 13: mainly 3.5 g carbohydrate). Additionally, both groups exercised (weight-bearing exercise, square stepping exercise) once a week for 75 min. Body composition, PA, and amino acid concentrations in the plasma were measured. Body weight, BMI, body mass, household PA, total PA, and phenylalanine significantly increased in the Ex + CIT·LEU group (p < 0.05) post intervention. This study suggests that the combined intake of CIT and LEU accompanied by exercise can improve body weight, BMI, body mass, and PA in older women with low BMI, which may prevent sarcopenia and frailty.

Macronutrient Distribution

A nutritional survey based on twelve adolescent male Kalenjin runners in Kenya during a 2-week field study was carried out in order to determine the composition of their diet and make a comparison with macronutrient recommendations for athletes. Food samples were collected for analysis of macronutrient distribution and energy content from main meals and the macronutrient distribution and energy content of additional food intake were based on the information of a 24 h recall interview and estimated from food tables. The diet of the Kalenjin runners was very high in carbohydrate (71 % 8·7 g/kg body weight per d) and very low in fat (15 %). Intake of total protein (13 %; 1·6 g/kg body weight per d) was above the daily intake recommended by the Food and Agriculture Organization/World Health Organization/United Nations University (FAO/WHO/UNU), while essential amino acid intake was estimated to be in the borderline-to-low range based on FAO/WHO/UNU recommendations for children <12 years and adults. The energy intake was mainly derived from vegetable sources (90 %) with maize and kidney beans as the staple food (81 %). The diet of the Kalenjin runners met recommendations for endurance athletes for total protein and most essential amino acid intake as well as carbohydrate intake even though it was based on a small range of food items.
