| Description | There has been an abundant of dietary analysis research conducted in male adult soccer players while, studies within youth players are lacking. Furthermore, the daily distribution of energy and macronutrient intake across the day have been reported to impact on training adaptations, but this is often not considered in the literature. The aims of this study were: to quantify daily energy and macronutrient intake and assess their distribution across five days; and to compare daily energy intake and predicted daily energy expenditure in under-16 male soccer players. The sample included 25 soccer participants aged 14.8-15.7 years-old. Five-day self-reported food diaries were used to collect the food/drink consumed. Intake was analysed for total daily energy and macronutrient intake, as well as the distribution between meals (breakfast, lunch, dinner and snacks). Daily energy expenditure was predicted by resting energy expenditure and physical activity level developed for youth sport participants. The total mean energy intake was 1928±388 kcal∙day-1 whereas the estimated daily energy expenditure was 3568 kcal∙day-1. The relative daily protein intake was lower at breakfast, morning snack, afternoon snack and night snack compared to lunch and dinner. Youth soccer players appear to not meet energy demands and daily CHO guidelines. Fluctuations across the day on protein intake were noted and may influence training adaptations (i.e. muscle protein synthesis and recovery). |
| Abstract | IntroductionThere has been an abundance of dietary analysis research conducted on adult male soccer players, while studies on youth players are lacking. Furthermore, the daily distribution of energy and macronutrient intake throughout the day has been reported to influence training adaptations, but this is often not considered in the literature. This study aims to quantify daily energy and macronutrient intake and assess their distribution over 5 days, and compare daily energy intakes and predicted daily energy expenditure in under-16 male soccer players.MethodsThe sample included 25 soccer participants aged 14.8–15.7 years. Five-day self-reported food diaries were used to record the food/drink consumption. Intake was analyzed for total daily energy, macronutrient intakes, and distribution among meals (breakfast, lunch, dinner, and snacks). Daily energy expenditure was predicted by resting energy expenditure and physical activity levels developed for youth sports participants.ResultsThe mean total energy intake was 1,928 ± 388 kcal∙day−1, whereas the estimated daily energy expenditure was 3,568 kcal∙day−1. Relative daily protein intakes were lower at breakfast, morning snack, afternoon snack, and night snack compared to lunch and dinner.DiscussionYouth soccer players do not appear to meet energy requirements and daily CHO guidelines. Fluctuations in protein intake throughout the day were noted and may influence training adaptations (i.e., muscle protein synthesis and recov... |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
