Profile of Cardiorespiratory Fitness, Flexibility and Fat Percentage of Junior High School Students in Jatinangor
Abstract: Obesity and physical
inactivity is a major risk factor for non-communicable disease and global
mortality in adolescent. Lack of physical activity will lead the condition into
poor physical fitness, measured by cardio respiratory fitness (maximum oxygen
volume, VO2 max), and other components such as flexibility. The study aimed to
describe VO2 max, flexibility and fat percentage among junior high school
students in Jatinangor.
Methods: The study was a descriptive observational study using
descriptive analysis. VO2 max was
assessed using Astrand Ryhming step test, flexibility was measured using
flexometer sit and reach test, and fat percentage was determined using
bioelectrical impedance analysis scale. The subjects were junior high school
students who were study in 1st, 2nd and 3rd grade in Jatinangor Junior High
School based on stratification sampling method. It was conducted from
September–October 2013.
Results: Total subjects were 110 students consisted of male (n=52) and
female (n=58). The VO2 max were in good
and above category, 57.69% of male (50.37 ± 9.80 ml/kg/min), and 60.34% of
female (37.66±7.03 ml/kg/min). The flexibility for both males and females were
within excellent category (67.31%, 26.56 ±7.14 cm and 67.24%, 27.29±6.64 cm
respectively). The fat percentage in females were within healthy category
(67.24%, 25.28 ± 6.85 %), meanwhile male were within underfat category (48.08%,
11.66 ± 5.83 %).
Conclusions: The majority of VO2 max, and flexibility both in male and
female were good. The fat percentages were good in female students, while in
male students were under normal range.
