N/A obesity. Intervention 1: Control group: Non-exercising control group advised to continue their usual daily routines. Intervention 2: Intervention group:The HIG programmes consisted of supervised aerobic dance sessions performed in the afternoon, three times weekly for eight weeks [23]. All sessions were preceded by a standardised five minute warm-up and concluded with a standardised five minute cooldown [23]. Exercise intensity was monitored continuously as heart rate (HR) using telemetry (Polar Accurex Plus Monitor, Polar Electro Oy, FIN-90440 Kempele, Finland) to ensure workload and the achievement of target heart rate. The HIG performed theirs at 76-95% HRmax for 30 minutes. An experienced Black African dance instructor led each dance session to local and international Black African music. Non-exercising control group participants were instructed to maintain their normal daily activities and dietary practices throughout the experimental period and were phoned three times weekly to ensure compliance. Intervention 3: Intervention group: The MIG programme consisted of supervised aerobic dance sessions performed in the afternoon, three times weekly for eight weeks. All sessions were preceded by a standardised five minute warm-up and concluded with a standardised five minute cooldown. Exercise intensity was monitored continuously as heart rate (HR) using telemetry (Polar Accurex Plus Monitor, Polar Electro Oy, FIN-90440 Kempele, Finland) to ensure workload and the achievement of target heart rate. The MIG participants performed their programme at 60-75% of heart rate maximum (HRmax) for 60 minutes. An experienced Black African dance instructor led each dance session to local and international Black African music. Non-exercising control group participants were instructed to maintain their normal daily activities and dietary practices throughout the experimental period and were phoned three times weekly to ensure compliance. Yes - There is a plan to make this available What will be shared: The analysis of information obtained from the results of the interventions onPrimary outcomes can be published When: From the time the article was published until a year later To whom: All researchers Conditions: Provided Someone wants to do a similar research project Where to obtain: r.khanmohamadi65@yahoo.com How to obtain: Send request by email Comments:

Non-exercising control group participants were instructed to maintain their normal daily activities and dietary practices throughout the experimental period and were phoned three times weekly to ensure compliance Body composition. Timepoint: before intervention and at 8 weeks after start of intervention. Method of measurement: Participants were evaluated for body composition as per the International Society for the Advancement of Kinanthropometry (ISAK) guidelines [20]. Body weight was measured and recorded (to the nearest 0.1 kilogramme (kg)) using a digital scale (Jawon, Model IOI-353, Kyungsun City, Korea), while body height was measured (to the nearest 0.5 cm) using a stadiometer (Marsden HM-250P Portable Height Measure, London, UK). Body mass index (BMI) was calculated by dividing the participant’s body mass (kg) by stature squared (m²) and expressed as kilogrammes per square meter (kg.m-2). Waist circumference was measured at the mid-point between the iliac crest and bottom of the ribcage while hip circumference measurement was taken at the widest circumference of buttocks and these two values were used to calculate the waist-to-hip ratio (WHR). Skinfolds of the triceps, subscapular, chest, mid-axillary, suprailiac, abdominal, and thigh were measured to the nearest 0.2 millimetres with a Holtain skinfold calliper (Holtain Ltd Crymych, UK). Body fat percentage (BF%) was calculated using the equation of Jackson and Pollock. Blood total cholesterol,. Timepoint: before intervention and at 8 weeks after start of intervention. Method of measurement: Following a nine to 12-hour overnight period of fasting and 48-hour period of no exercise, blood glucose and total cholesterol (TC) were assessed from capillary blood samples collected through transcutaneous puncture on the medial side of the tip of the middle finger using a disposable hypodermic lancet. Prior to puncture, 70% alcohol was used to promote antisepsis. The first drop of blood was discarded, and the following were used in random order for the analyses using a validated and reliable point-of-care (POC) monitoring device (Accutrend Plus system, Roche Diagnostics, USA). The Accutrend Plus system has previously demonstrated good reproducibility (Lin's coefficient: glucose = 0.958, and TC = 0.940) and high concordance with the laboratory method (Lin's coefficient: glucose = 0.952, and TC = 0.944) and high sensitivity (glucose = 80.0%, and total cholesterol = 84.4%) and specificity (glucose = 100.0%, and total cholesterol = 95.2%).

Cardiovascular fitness. Timepoint: before intervention and at 8 weeks after start of intervention. Method of measurement: Cardiorespiratory fitness (VO2max) was evaluated using the 20-metre shuttle run test [22]. For this test, participants were instructed to run back and forth shuttles between two cones placed 20 metres apart from each other. The pace of participants was controlled by an audible beep on a pre-recorded tape that sounded each time the participant was expected to reach the cone for the completion of a shuttle. The test was automatically cancelled if a participant failed to complete two successive shuttles. VO2max was estimated by retroextrapolating the oxygen recovery curve at time zero of recovery [22].
