To assess aerobic fitness in male and female adolescents using the multistage 20-metre shuttle run test and correlate it with selected fitness variables.
The subjects comprised 83 girls and 64 boys aged 15-16 years, randomly selected from two segregated government schools in Muscat. After the pupils filled in a short questionnaire on their personal leisure time activities of the preceding week, their heights and weights were measured. Aerobic fitness was assessed by estimating each pupil's minimal oxygen uptake levels (VO2max) using the multistage 20-metre shuttle running test (20-MST).
Boys spent more time than girls on leisure physical activities, television, computer and video games and the Internet. The estimated VO2max in both boys and girls showed high correlation with their weekly physical activities. The time spent on television and computer negatively correlated with VO2max in girls but not in boys. Girls had higher body mass index (BMI) and less VO2max compared to boys; BMI showed a negative correlation with VO2max in girls but not in boys.
Aerobic fitness in this sample was higher in boys than in girls and was strongly influenced by weekly physical activities in both genders. The 20-MST has proved a simple and inexpensive field test for aerobic fitness that could be implemented on a wide scale.
使用20米往返跑多级测试评估青少年男性和女性的有氧适能，并将其与选定的体能变量相关联。
研究对象包括从马斯喀特两所隔离的政府学校中随机选取的83名15 - 16岁女孩和64名男孩。学生填写一份关于前一周个人休闲时间活动的简短问卷后，测量他们的身高和体重。使用20米往返跑多级测试（20-MST）评估每个学生的最低摄氧量水平（VO2max），以此来评估有氧适能。
男孩在休闲体育活动、看电视、玩电脑和电子游戏以及上网方面花费的时间比女孩多。男孩和女孩的估计VO2max都与他们每周的体育活动高度相关。女孩花在电视和电脑上的时间与VO2max呈负相关，而男孩则不然。与男孩相比，女孩的体重指数（BMI）更高，VO2max更低；BMI在女孩中与VO2max呈负相关，而在男孩中则不然。
该样本中男孩的有氧适能高于女孩，且有氧适能在两性中均受到每周体育活动的强烈影响。20-MST已被证明是一种简单且经济的有氧适能现场测试方法，可广泛应用。
