RESUMEN

The aim of the present study was to understand the reasons to join or to continue in a physical exercise programme based on the perceptions of the older adults participating in the study. Four focus groups were selected in various contexts, with a total of 39 older adults. An emergent induction analysis methodology was applied, handling the participants' speeches from the specific to the general through the coding process proposed in the grounded theory. The differences among contexts regarding personal reasons for physical practice were presented, as well as the role of physical and psychological benefits, and body image. The participants of this research engaged in physical exercise to pursue physical health benefits in the first place, followed by psychological well-being, and leaving body image aside (AU)

Este estudio se realizó para tratar de comprender cuáles son los motivos encontrados al unirse a programas o mantener la práctica de ejercicio físico en base a las percepciones de las personas adultas mayores que participan en el estudio. Se realizaron cuatro grupos focales en diferentes contextos con un total de 39 adultos mayores. El análisis metodológico es inductivo, emergente, delimitando los discursos de los participantes del estudio de lo específico a lo general, a través del proceso de codificación de la teoría fundamentada. Se presentaron las diferencias entre contextos sobre los motivos de carácter personal para la práctica física, el papel de los beneficios físicos, psicológicos y la imagen corporal. Los participantes de esta investigación realizan ejercicio físico buscando en primer lugar los beneficios para la salud física, seguido del bienestar psicológico y dejando de lado la mejora de la imagen corporal (AU)

RESUMEN

OBJECTIVE: This study aimed to evaluate the influence of a 16-week concurrent exercise program on health-related quality of life in middle-aged women. METHODS: A total of 150 middle-aged women from the FLAMENCO project (age range 45-60 years) were randomized into a counseling (n = 75) or an exercise (n = 75) group. The exercise group followed a 16-week (3 days/week, 60 min/session) concurrent exercise program (aerobic + resistance training). The counseling group attended conferences on a healthy lifestyle. Participants' health-related quality of life was assessed with the EuroQol plus, a visual analog scale and the 36-item Short Form Health Survey (SF-36), where greater values indicate a better health-related quality of life. RESULTS: The visual analog scale increased by 9.0% in the exercise group, whereas it only increased by 3.5% in the counseling group (p = 0.040). The SF-36 physical function, physical role, bodily pain, vitality and emotional role increased by 5.5%, 11.3%, 10.8%, 9.6% and 8.9%, respectively, in the exercise group, whereas these only increased by 0.6%, decreased by 0.7% and increased by 1.4%, 3.8% and 0.6% in the counseling group (all p < 0.05). CONCLUSIONS: Our results suggest that a 16-week concurrent exercise program adapted for midlife women improved their health-related quality of life. CLINICALTRIALS.GOV IDENTIFIER: NCT02358109.

RESUMEN

BACKGROUND: The Homeostatic Measurement Assessment-Insulin Resistance (HOMA-IR) is a recognized and validated method which uses the levels of fasting glucose in blood and insulin of patients to evaluate the insulin resistance. AIMS: The purpose of the present study was to assess the cut-off values for anthropological variables to identify the (HOMA-IR) index in female participants of a physical exercise program. In addition, the association and prediction of insulin resistance by anthropological variables was studied. METHODS: A total of 143 participants (45.64 ± 13.17 years) volunteered for this study. Clinical data were collected by means of a self-reported questionnaire. Body weight and BMI were assessed by bioelectrical impedance analysis and skinfold thickness was taken using a caliper. Girths were assessed with a flexible metallic tape measures and finally, the HOMA-IR was calculated by the formula as follows: fasting plasma insulin ((µU/ml) x fasting plasma glucose (mmol/L). RESULTS: The outcomes of the study indicated that the AUC of anthropometrical variables for identifying HOMA-IR are reflected primarily in weight, waist-to-hip ratio, waist-to-thigh ratio, subscapular skinfold thickness, abdominal skinfold thickness, hip circumference, chest circumference, upper arm muscular girths (tensed and relaxed) (all, p ≤ 0.001), triceps skinfold thickness (p 109 cm (specificity: 99.2  waist circumference > 116 cm (specificity: 99.2 %) and abdomen skinfold < 8.8 (specificity: 97.6 %), predict the HOMA-IR in 35.29 %, 29.41 %, 23.53 % and 23.53 %, respectively. CONCLUSION: The present empirical study demonstrates that hip, chest and waist circumference on the one hand, and abdomen skinfold on the other hand are markers that are relevant to the identification of HOMA-IR index in females (Tab. 3, Ref. 33).

RESUMEN

OBJECTIVES: This study aimed to explore the association of physical fitness with health-related quality of life (HRQoL) in mid-life women and to examine the potential independent association of physical fitness components with the physical and mental components from the 36-Item Short-Form Health Survey (SF-36) in this population. METHODS: This cross-sectional study comprised 183 mid-life women from southern Spain who participated in the FLAMENCO project. Body composition was measured through an impedanciometer, a stadiometer, and dual-energy X-ray absorptiometry. Physical fitness was objectively measured with the Senior Fitness Test battery (cardiorespiratory fitness, flexibility, and dynamic balance/agility) plus handgrip strength (muscle strength). The SF-36 questionnaire was used to assess HRQoL of the participants. RESULTS: All the physical fitness components were associated with the SF-36 physical function (all p < 0.05) except for lower-body flexibility. The rest of the physical fitness components showed associations with most of the SF-36 dimensions (all p < 0.05). Dynamic balance/agility and upper-body flexibility were independently associated with the SF-36 physical component scale, explaining 15% and 17% of the SF-36 physical component scale, respectively. Any physical fitness component showed independent associations with the SF-36 mental component scale. CONCLUSIONS: Greater physical fitness levels are associated with better HRQoL of mid-life women. Dynamic balance/agility and upper-body flexibility were the strongest independent physical fitness components associated with the SF-36 physical component scale.
