Bone Mineral Density and Bone Metabolism in Older Women

Summary

The objective of this study is to assess the impact of different exercise interventions on bone mineral density (BMD) in older women. It will also evaluate the safety and compliance of these interventions. The primary questions it aims to address are:

Does resistance training, Yijinjing, or Baduanjin improve BMD in postmenopausal women? What are the compliance rates and any adverse effects associated with these exercise programs? Participants will be divided into 4 groups and compared against a control group that maintains their usual lifestyle.

Participants will:

Engage in their assigned exercise program three times a week for 24 weeks Receive calcium and vitamin D supplementation daily Keep a log of exercise adherence and any side effects experienced The study will utilize the International Physical Activity Questionnaire and dual-energy X-ray absorptiometry for comprehensive assessments.

Interventions

OTHER

Resistance training

RG performed RT with an elastic band (yellow, force of 9-11 pounds when stretched twice the original length). They performed eight movements. Each movement was performed for 3-5 sets at 8 times/sets with 30 s of rest between groups. The movements included upright rows, reverse curls, standing shoulder rotations, neck-elbow extensions, elbow bends, downward lunges, standing leg lifts, side lifts and standing back kicks. All participants completed the RT movements according to the regular rhythm (1-2-1) provided by the experimenter, which ensured that all participants had similar movements completion rates.

OTHER

Yijinjing

YG performed 12 movements . These movements included extending the hands upwards and slowly lowering them; extending the torso by stretching the hands straight up and bending the body to the left or right; squatting with the hands on the knees and standing up slowly; bending the body to the left or right side, extending the arms and waist; getting down on the knees, leaning forward, extending the hands forward and slowly pulling them back; bending forward, placing the hands around the knees and standing up slowly; placing the hands on the hips; and leaning back to stretch the back and waist.

OTHER

Baduanjing

BG performed eight movements . These movements included holding the hands straight up, slowly bringing the hands down and turning the waist while in a standing position; bending the body to the left or right side and extending the arms; extending one hand straight up, placing the other hand on the waist, then switching arms and repeating the movement; tilting the head back and looking back while stretching the neck and back; squatting the body, swinging the head and hips from side to side and moving the spine and waist; bending the body forward, touching the hands to the toes and standing up slowly; making fists with the hands and moving the arms and shoulders; and gently bouncing the body to relax the whole body in a standing position.
