Key result
Concurrent training for 12 weeks significantly improved body mass, body fat, muscle mass, and total cholesterol in both Mapuche and European hyperglycemic women (P<0.0001).
Why the study?
The study aimed to investigate the effects of 12 weeks of concurrent training (high-intensity interval and resistance training) in Mapuche adults from Chile and in their peers of European descent.
Does 12 weeks of concurrent training improve cardiometabolic risk factors in hyperglycemic Mapuche and European descent adult women?
Does 12 weeks of concurrent training improve cardiometabolic risk factors in hyperglycemic Mapuche and European descent adult women?
p-value: p=<0.0001
A 12-week concurrent training program improves cardiometabolic risk factors similarly in hyperglycemic women of Mapuche and European descent.
May support concurrent training for body composition and lipids in hyperglycemic women; leaves open causality and generalizability pending RCTs.
Our aim was to investigate the effects of 12 weeks of CT (ie, high-intensity interval and resistance training) in Mapuche adults from Chile and in their peers of European descent. In total, 96 hyperglycemic adult women (mean age 46 years [95% confidence interval; 38, 53]) were divided in four groups: Mapuche CT (Map-CT, n = 14) or control group (Map-CG, n = 44), and European CT (Eur-CT, n = 14) or control group (Eur-CG, n = 23). The following endpoints were analyzed at baseline and after 12 weeks: anthropometric (body mass, body mass index, waist circumference), body composition (fat mass, muscle mass, lean mass), cardiovascular (systolic [SBP]/diastolic [DBP] blood pressure), metabolic (blood fasting glucose and total cholesterol), and muscle strength (handgrip of dominant/non-dominant arm). There were significant positive changes in body mass, body fat, and muscle mass (P < 0.0001) in both Map-CT and Eur-CT groups, whereas waist circumference was decreased significantly only in the Eur-CT group (P < 0.0001). Both Map-CT and Eur-CT groups showed decreased levels of fasting glucose (P < 0.05) and total cholesterol after the intervention (P < 0.0001). Also, both Map-CT (P < 0.05) and Eur-CT (P = 0.01) groups showed a lowered SBP. Finally, significant increases were observed after training in handgrip strength (dominant arm) in Map-CT and Eur-CT groups (both P < 0.0001). CT led to similar improvements in cardiometabolic risk factors for metabolic syndrome development in Mapuche and European participants, with additional improvements in other anthropometric, body composition, cardiovascular, metabolic, and muscle strength parameters related to the prevention of metabolic syndrome. These results suggest future more complex studies.

Álvarez et al. (2019) studied Hyperglycemia / Cardiometabolic risk (n=96). Concurrent training (high-intensity interval and resistance training) vs. Control group was evaluated on Anthropometric, body composition, cardiovascular, metabolic, and muscle strength parameters (p=<0.0001). Concurrent training for 12 weeks significantly improved body mass, body fat, muscle mass, and total cholesterol in both Mapuche and European hyperglycemic women (P<0.0001).
