Abstract

The purpose of this study was to determine the effects of a 10-week physical activity (PA) intervention on selective metabolic syndrome markers in black adolescents. All available adolescents (194 subjects), boys and girls, in the grade 9 class (15-19 years) attending a secondary school were recruited for the experimental group. A control group consisting of 57 adolescents from grade 9 of another secondary school in the same area was also recruited. The experimental group participated in a 10- week PA intervention. Body mass index (BMI), fasting insulin, fasting glucose, homeostasis model assessment of insulin resistance (HOMA-IR), systolic blood pressure (SBP), diastolic blood pressure (DBP), Windkessel arterial compliance (Cw), total peripheral resistance (TPR) and waist circumference were measured. After the 10-week PA intervention, adolescents from the control group had a significantly lower DBP compared to the intervention group (p=0.00005) and adolescents from the intervention group had a significantly lower SBP compared to the control group (p=0.000061). There was also a tendency towards a higher Cw and lower HOMA-IR in the intervention group compared to the control group. The findings of this study suggest that black adolescents had significantly lower SBP and a trend of lower HOMA-IR after a 10-week PA intervention. Key words: Physical activity; Metabolic syndrome; Adolescents.

为期10周的体育活动干预计划对黑人青少年选择性代谢综合征标志物的影响

本研究的目的是确定为期10周的体育活动(PA)干预对黑人青少年选择性代谢综合征标志物的影响。实验组招募了一所中学九年级(15-19岁)所有可用的青少年(194名)，包括男孩和女孩。另外还招募了来自同一地区另一所中学九年级的57名青少年作为对照组。实验组接受为期10周的PA干预。测量体重指数(BMI)、空腹胰岛素、空腹血糖、胰岛素抵抗稳态模型评估(HOMA-IR)、收缩压(SBP)、舒张压(DBP)、Windkessel动脉顺应性(Cw)、总外周阻力(TPR)和腰围。经过10周PA干预后，对照组青少年的舒张压明显低于干预组(p=0.00005)，干预组青少年的收缩压明显低于对照组(p=0.000061)。与对照组相比，干预组也有更高的Cw和更低的HOMA-IR的趋势。本研究的结果表明，黑人青少年在经过10周的PA干预后，收缩压明显降低，HOMA-IR也有降低的趋势。关键词:体育活动;代谢综合征;青少年。

期刊介绍： The South African Journal for Research in Sport, Physical education and Recreation (SAJRSPER) is a peer-reviewed journal that publishes original research articles, systematic reviews, commentaries, and letters on topics related to Sport and Exercise science, Physical education and Recreation. This includes research of topics such as bio-mechanics, motor control, sport injuries and rehabilitation, clinical exercise interventions, physical education, as well as outdoor and recreation related topics. Material that is particularly unique and relevant to the subject content at an international and national level would be considered.
