Objectives:
To determine the effects of high-intensity multimodal exercise training on bone mineral density and muscle performance in postmenopausal women.
Methods:
The two-armed, parallel, pilot randomised controlled trial was conducted from November 2020 to July 2021 at Riphah Rehabilitation Centre, Rawalpindi, Pakistan, and comprised women aged 45-70 having been in the post-menopause phase for at least 3 years, with body mass index <30, community ambulant and willing to have exercise therapy. The subjects were randomised into two equal groups. The experimental group A received supervised high-intensity resistance, weight-bearing, balance and mobility training twice weekly for 8 months. The control group B received low-to-moderate intensity exercises. Femoral neck and lumbar spine bone mineral density (g/cm2) were taken through a dual-energy X-ray absorptiometry scan. Muscle performance was measured using 1 repetition maximum for leg and trunk extensors, and 30 sec sit to stand test. Data was analysed using SPSS 21.
Results:
Of the 101 women screened, 28(27.7%) were enrolled; 14(50%) in group A having mean age 53.36±6.28 years, and 14(50%) in group B having mean age 51.71±4.82 years (p>0.05). Group A showed significantly more improvement than group B both with respect to lumbar spine bone mineral density and muscle performance (p<0.05).
Conclusions:
Supervised high-intensity multimodal exercise training protocol had a positive effect on lumbar spine bone mineral density and muscle performance in postmenopausal women.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
