Effects of a 20-Week Concurrent Training Program on Bone Metabolism in Elderly Women

Abstract

The present study evaluated the effect of a 20-week concurrent training program on bone metabolism in elderly women. The sample consisted of 51 elderly women living in the municipality of Muriaé (MG), distributed into two groups: a concurrent training group (CTG = 25), with an average age of 69.44 ± 6.82 years, and a control group (CG = 26), with mean age of 68.30 ± 6.34 years. Biophysical parameters were determined based on weight, height and body mass index. Bone metabolism was assessed by collecting second-morning urine samples before and after intervention to analyze levels of the biochemical marker deoxypyridinoline (DPD), which quantifies bone resorption. Results: The results showed a post-intervention decline in DPD content in the GTC when compared to controls (p = 0.007) and an improvement in the variables weight, BMI and DPD between the GTC and GC (p = 0.000). Conclusion: Concurrent training was efficient in improving bone metabolism in the elderly population studied.

Effect on the functionality of elderly obese, after exercise guidelines and nutritional intervention. Systematic review.

“…In turn, high-intensity interval training is more effective, faster, and has a more significant effect (11). To improve body mass index and bone mineral density in older adults, researchers recommend performing strength training exercises for 30 minutes, three times per week, with three series of 8-10 repetitions, with breaks of 1-2 minutes between series, with a load of 70% and 85% of 1RM, accompanied by cardiovascular resistance training three times a week for 30 minutes at the intensity of 70-89% of the reserve heart rate (12). In addition, resistance training has benefits for cardiovascular health, weight management, prevention of disability and falls, because the loss of muscle mass and strength is a determinant of functionality and reduction of quality of life (7).…”

Profile and Reference Values for Body Fat and Skeletal Muscle Mass Percent at Females, Aged from 18.0 to 69.9, Measured by Multichannel Segmental Bioimpedance Method: Serbian Population Study

“…A system for controlling the status of body composition, through continued monitoring of the given state of the organism, is increasingly becoming a part of the very important health mechanism with the goal of tracking the condition and ascertaining the trends of change in the given conditions among the general populace (Gába & Pridalová, 2014;Ihász et al, 2015) or some specific population, such as athletes, regardless of sex, age or type of sport (Dopsaj et al, 2017;Bankovic et al, 2018). Also, defining the characteristics of the model for the body composition status condition among people represents an expert and scientific attitude of decision making on whether a certain tissue component is insufficiently, normally or predominantly represented in the body (Bankovic et al;Saraykin et al, 2018), that is, if there exists an effect of an applied treatment and how big it is, regardless whether it is diet correction or physical activity treatment (Rocha et al, 2018). This is even more pronounced with the advent of new technologies for the measurement of body components, based on the principle of bioimpedance, and especially new technology of multichannel multisegment bioimpedance as being very medically precise and easily available measurement technology for all body composition characteristics (Ling et al, 2011;Saraykin et al).…”
