    The aim of this study was to determine the effects of a muscular strength programme on the levels of insulin-like growth factor-1 (IGF-1) and cognitive status in elder women with mild cognitive impairment who lived in areas of high air pollution. A total of 157 women participated in the study, distributed in four groups: Active/Clean (AC n = 38) and Active/Pollution (AP n = 37), who carried out a progressive resistance training programme for 24 months, and Sedentary/Clean (SC n = 40) and Sedentary/Pollution (SP n = 42). Maximum strength in the upper and lower limbs (1RM), cognition (Mini-Mental Scale Examination (MMSE)) and blood IGF-1 were evaluated. At the beginning of the intervention, there were no differences between the groups in the assessed variables. The active groups which carried out the resistance training programme (AC and AP), registered better results in IGF-1 than the sedentary groups. These differences were statistically significant in AC vs. SC (p < 0.01) and AP vs. SC (p < 0.05). Regarding MMSE, group AC registered the highest score increases (+8.2%) (significantly better than the other groups), while group SP worsened (−7%) significantly compared to the other three groups. In conclusion, resistance training had a positive effect on IGF-1, while sedentary behaviour and air pollution had a negative effect on cognitive status. © 2020 by the authors.

    Introduction: The effect of two physical training methods on older adults should be in-vestigated in greater depth and its results shared with the community. Objective: To determine the effects of two types of physical training on the functional features associated with the cognitive state and the effect on a physiological mediator of growth hormone (IGF-1) in older women. Material and Methods: Quasi-experimental study that included 12 weeks of training in two groups divided into resistance and aerobic training. The study included a population of 113 women aged 69.39 ± 6.48 years from Talcahuano, Chile. All participants were randomly assigned to either group. The MINIMENTAL test was used to examine the executive functions of cognitive state and blood con-centration of IGF-1, which was also used to examine neurotrophic factors. For the assessment of physical condition, an indirect test was used for the maximum mass displaced in one repetition (1RM) by the limbs and the TM6 test to estimate maximal oxygen consumption. Results: Significant differences between the groups with respect to the total score obtained in the MINIMENTAL test (EG1 = 28.13 ± 2.26; EG2 = 28.57 ± 1.83 and CG = 23.47 ± 2.80; ANOVA; p = 0.000) were observed. A post hoc analysis revealed no significant differences when examining executive functions individually between groups (Bonferroni; p > 0.05). An increase in the neurotrophic factor IGF-1 was also recorded in the training groups (EG1 p = 0.014 and EG2 p = 0.005). The pre-and post-test showed large differences in magnitude in the resistance training group (ES = 0.9; 20.41% change). Conclu-sion: Both workouts produce an overall improvement in the functions associated with cognitive status and increase blood concentrations of IGF-1 in older adults. © 2021 by the authors.

    Lifestyle and cardiometabolic risk factors in the ethnic and non-ethnic population > 15 years of age: results from the National Chilean Health Survey 2016-2017
    (ARAN Ediciones S.L, 2023-03) Álvarez, Cristian; Ramírez-Campillo, Rodrigo; Miranda-Fuentes, Claudia; Ibacache-Saavedra, Paulina; Campos-Jara, Christian; Cristi-Montero, Carlos; Molina-Sotomayor, Edgardo; Caparrós-Manosalva, Cristian; Delgado-Floody, Pedro
    Background: lifestyle and cardiometabolic risk factors information is scarce regarding youth and adults of Latin-American ethnics. Objective: the primary aim was to describe the lifestyle and cardiometabolic risk factors for arterial hypertension (HTN) and diabetes in ethnic Latin-American groups (Mapuche and Aymara) and other non-ethnics > 15 years of age in the Chilean population. A secondary aim was to determine the association between physical activity ‘intensity’ with HTN and diabetes markers. Material and methods: a representative sample from the National Chilean Health Survey 2016-2017, included Mapuche (EG-Map; women n = 166, men n = 300; total n = 466), Aymara (EG-Aym; women n = 96, men n = 55; total n = 151), and a non-ethnic population group (No-EG; women n = 2057, men n = 3445; total n = 5502). The main outcomes were; systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (GL), and secondary outcomes were other anthropometric, lipid profile, and lifestyle parameters. Results: GL was significantly associated with nutrition (0.9 %, p < 0.0001), tobacco and alcohol habits (0.6 %, p < 0.0001). SBP was significantly associated with nutrition (whole-grains 0.04, p = 0.001; water consumption 0.07, p < 0.0001), sleep hygiene (week 0.04, p = 0.030; on weekends-0.04, p = 0.026), and alcohol consumption (-0.06, p < 0.0001). Conclusion: in conclusion, lifestyle differences among Mapuche and Aymara ethnic groups in comparison with non-ethnic Chilean peers > 15 years are significantly associated with blood pressure and glycemia. © 2023 SENPE y©Arán Ediciones S.L.
