The effects of concurrent training (aerobic-resistance) and milk consumption on some markers of bone mineral density in women with osteoporosis

Abstract

BackgroundOsteoporosis is a skeletal metabolic disorder characterized by low bone mineral density (BMD) and reduced bone strength leading to higher bone fractures risk. The present study attempted to investigate the effects of concurrent training (aerobic-resistance) and milk consumption on some markers of BMD in women with osteoporosis.MethodsFor this purpose, forty women diagnosed with osteoporosis within an age range of 30-45 years were divided into four groups of ten including concurrent training-milk, concurrent training, milk consumption and control group. The concurrent exercises were performed in ten weeks with three sessions in each week including aerobic training (running at 55–75% of maximum heart rate) and resistance training (4 move in a circle performed two times with 10 repetition maximum (RM)). Milk consumption was two times of 250 ml per day in ten weeks. Before and after treatment, BMDs in the hip and lumbar spine area were estimated with Dual-energy X-ray absorptiometry (DEXA) device and 5 cc blood was taken from a vein in the arm to determine the blood levels of 25-hydroxyvitamin D (25OH-D) and alkaline phosphatase (ALP).ResultsBased on the results, blood levels 25OH-D and ALP significantly increased in concurrent training-milk, concurrent training and milk group with higher increase in concurrent training-milk group (P < 0.05). Furthermore, the right and left hip BMD in concurrent training-milk and concurrent training groups increased significantly with higher increase in concurrent training-milk group (p < 0.05). Also, lumbar spine BMD increased significantly in concurrent training-milk and concurrent training (p < 0.05).ConclusionsIt seems that combination of concurrent training and milk consumption has more efficient impacts on the BMD of young women diagnosed with osteoporosis compared to the milk or concurrent training groups alone. This treatment can be used as an effective way to improve BMD in young women with diagnosed osteoporosis.

Osteoporosis in Premenopausal Women: A Clinical Narrative Review by the ECTS and the IOF

“…Forty young women, aged 30 to 45 years and recently diagnosed with osteoporosis, were divided into 4 groups with the following interventions over a period of 10 weeks: training (aerobic-resistance) group plus milk consumption (500 mL daily), only milk consumption, only training and controls. This study showed that there were significant differences in hip and LS BMD in the training plus milk group with higher values compared to training, milk consumers, and control groups (101). However, the small sample size and short duration of intervention limit a clinical translation of these findings.…”

“…Recently, new evidence on the effects of physical activity in premenopausal women has been published (101,102). Forty young women, aged 30 to 45 years and recently diagnosed with osteoporosis, were divided into 4 groups with the following interventions over a period of 10 weeks: training (aerobic-resistance) group plus milk consumption (500 mL daily), only milk consumption, only training and controls.…”

The Effect of Physical Activity on Bone Biomarkers in People With Osteoporosis: A Systematic Review

“…Most of the articles included in the preliminary full text analysis from the database research involved osteopenic people without osteoporosis, and they did not meet the established inclusion criteria. For this reason, our findings focused on data from only three studies (32)(33)(34). Regarding the bone biomarkers assessment, all the studies investigated the serum ALP.…”

“…Furthermore, the majority of the articles were excluded due to the samples that did not match our inclusion criteria (people with osteopenia and not osteoporosis). As a result, only three papers (32)(33)(34) were finally included in the systematic review, fully meeting the eligibility criteria (Figure 1).…”

“…There was no blinding of participants (item #4), but the review authors judge that the biomarker outcome is not likely to be influenced by lack of blinding of participants. Regarding the blinding of outcome assessment (item #5) Roghani et al was the only one that described and used techniques and methods that ensure the sensitivity of outcome assessment (32); the studies by Arazi et al (33) and El-Mekawy et al (34) were not clear in describing the methodology used to guarantee no risk of bias of outcome assessors. Overall, each RCT had one or more criteria unclear.…”
