The purpose of this study was to examine the association between muscular fitness (MF), assessed by 2 components of Fitnessgram test battery, the Curl-Up and Push-Ups tests and the metabolic risk score among adolescent girls.
A total of 229 girls (aged 12-15 years old) comprised the sample of this study. Anthropometric data (height, body mass, waist circumference) were collected. Body mass index (BMI) was also calculated. Muscular strength was assessed taking into account the tests that comprised the FITNESSGRAM test battery, i.e. the curl-up and the push-up. Participants were then categorized in one of 3 categories according the number of tests in which they accomplished the scores that allow them to be classified in health or above health zone. The blood pressure [BP], fasting total cholesterol [TC], low density lipoprotein-cholesterol [LDL-C], high density lipoprotein-cholesterol [HDL-C], triglycerides [TG], glucose, and a metabolic risk score (MRS) were also examined. Physical Activity Index (PAI) was obtained by questionnaire.
Higher compliance with health-zone criteria (good in the 2 tests), adjusted for age and maturation, were positive and significantly (p </= 0.05) associated with height (r = 0.19) and PAI (r = 0.21), while a significant but negative association was found for BMI (r = -0.12); WC (r = -0.19); TC (r = -0.16); TG (r = -0.16); LDL (r = -0.16) and MRS (r = -0.16). Logistic regression showed that who were assigned to MF fittest group were less likely (OR = 0.27; p = 0.003) to be classified overweight/obese and less likely (OR = 0.26; p = 0.03) to be classified as having MRS. This last association was also found for those whom only performed 1 test under the health zone (OR = 0.23; p = 0.02).
Our data showed that low strength test performance was associated with increased risk for obesity and metabolic risk in adolescent girls even after adjustment for age and maturation.
本研究的目的是探讨肌肉健康（MF）与代谢风险评分之间的关系，MF 通过 Fitnessgram 测试电池的两个组成部分，即仰卧起坐和俯卧撑来评估，而这两个组成部分与青少年女孩有关。
本研究共纳入 229 名 12-15 岁的女孩。收集了人体测量数据（身高、体重、腰围）。还计算了体重指数（BMI）。肌肉力量评估考虑到 Fitnessgram 测试电池的测试，即仰卧起坐和俯卧撑。然后根据他们在健康或以上健康区完成得分的测试数量，将参与者分为 3 个类别之一。还检查了血压[BP]、空腹总胆固醇[TC]、低密度脂蛋白胆固醇[LDL-C]、高密度脂蛋白胆固醇[HDL-C]、甘油三酯[TG]、葡萄糖和代谢风险评分（MRS）。通过问卷获得身体活动指数（PAI）。
更高的健康区标准（两个测试均达标）的依从性，调整年龄和成熟度后，与身高（r = 0.19）和 PAI（r = 0.21）呈正相关且具有统计学意义（p </= 0.05），而 BMI（r = -0.12）、WC（r = -0.19）、TC（r = -0.16）、TG（r = -0.16）、LDL（r = -0.16）和 MRS（r = -0.16）呈负相关且具有统计学意义。Logistic 回归显示，被分配到 MF 最健康组的人不太可能（OR = 0.27；p = 0.003）被归类为超重/肥胖，也不太可能（OR = 0.26；p = 0.03）被归类为患有 MRS。对于那些仅在健康区下进行 1 项测试的人，也发现了这种关联（OR = 0.23；p = 0.02）。
我们的数据表明，即使在调整年龄和成熟度后，低强度测试表现与青少年女孩肥胖和代谢风险增加有关。
