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.
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.
