Assessing Musculoskeletal Fitness Using Standing Long Jump Test Among SMA Negeri 49 Jakarta Students in 2017
Abstract
Musculoskeletal fitness is one component of fitness that is important for health and research about it in Indonesia is still rarely done, whereas it is closely related to prevention of the occurrence osteoporosis, metabolic syndrome, cardiovascular disease, heart failure, diabetes mellitus, and obesity which remain health problem. Measuring adolescent musculoskeletal fitness could use Standing Long Jump (SLJ) test which is easy, valid, reliable, and widely used for fitness measurement globally. The aim of this study was to determine the average musculoskeletal fitness and the factors that contribute. This study was a quantitative study conducted using a cross-sectional design with 133 people as the sample population. The mean value of musculoskeletal
fitness using SLJ method in the sample study was 154.11 ± 37.33 cm. The score for boys was 184.76 ± 27.4 cm while for girls was 126.53 ± 19.03 cm. Bivariate analysis showed that there was a positive correlation between physical activity, energy, protein, fat, and carbohydrate intakes with musculoskeletal fitness while it showed the negative correlation between BMI for age and body fat percentage with musculoskeletal fitness.
