Plain English Summary
Background and study aims
Low bone mass, also known as osteopenia, is a condition in which a person’s bones are less dense than average. In some cases, it can lead to further bone loss and a condition called osteoporosis. Osteoporosis is a long term condition, which gets progressively worse, which makes bone weak, brittle and more likely to break. This deterioration can weaken the bones so much that person with low bone mass can suffer a fracture during everyday activities, such as lifting a bag of groceries. There is a great deal of evidence that weight-bearing and resistance exercises support the development of strong bones because the strain put on bones causes them to become more dense (osteogenic). The aim of this study is to compare the effects of a single session of resistance exercise or walking on the chemical indicators (biomarkers) of bone metabolism (breakdown) in people with low bone mass.
Who can participate?
Women with osteoporosis/osteopenia
What does the study involve?
Participants re randomly allocated to one of three groups. Those in the first group take part in a single session of resistance training, which lasts for around 46 minutes. This involves a series of exercises that use large muscle groups and major joints to strengthen muscles. Those in the second group take part in a single session involving moderate intensity brisk walking outdoors on even ground. Participants maintain their pace by keeping to a rhythm of 100 steps per minute for around 46 minutes. Those in the third group do not take part in any exercises. At the start of the study and then again within 5 minutes of completing the exercises, all participants have a sample of blood taken so that indicators of bone metabolism can be measured. Additionally, at the start of the study, participants have their bone mineral density measured using a type of x-ray.
What are the possible benefits and risks of participating?
Participants benefit from receiving information about their bone mineral density. There is a small risk of bruising or discomfort during and after blood tests.

Scientific title | Direct effects of physical training on markers of bone metabolism and serum sclerostin concentrations in older adults with low bone mass |
Study hypothesis | The aim of this study is to examine the direct effects of a single session of resistance exercise or walking on biochemical markers of bone metabolism in participants with low bone mass. |
Ethics approval(s) | 1. Regional Committee of Science and Research Ethics, 24/11/2011, ref: 46/2011 2. Policy Administration Service of Public Health of Zala County, 09/03/2015, ref: ZAR/097/194-8/2015 |
Condition | Low bone mass |
Intervention | The participants were randomly assigned to a resistance exercise group (RG; n = 50), walking group (WG; n = 50), or control group (CG; n = 50). Resistance exercise group: Participants take part in a single resistance training exercise session. This involves 8 minutes of dynamic warm-up consisting of exercises requiring movements of large muscle groups and major joints that incorporated small impacts with the ground, approximately 30 minutes of exercises that include muscle-strengthening and core stabilization elements, and an 8 minute cool down consisting of walking and static and dynamic stretches was performed. Walking group: Participants take part in a single session involving moderate intensity brisk walking to a rhythm (100 steps/min) provided by a metronome, continuously for 46 minutes outdoors on even ground. Control group: Participants continue as normal and do not receive any interventions. |
Intervention type | Behavioural |
Primary outcome measure | 1. Bone-specific alkaline phosphatase (BALP) concentration is measured using a photometric assay at baseline and immediately after the intervention 2. Carboxy-terminal cross-linked telopeptide of type I collagen (CTX) concentration is measured using an electrochemiluminescence immunoassay (ECLIA) at baseline and immediately after the intervention 3. Serum sclerostin concentration is measured using a qualitative sandwich enzyme-linked immunosorbent assay (ELISA) at baseline and immediately after the intervention Several assistants performed sample collection simultaneously to ensure rapid collection within 0 –5 minutes after the exercise sessions. |
Secondary outcome measures | Bone mineral density (BMD) is determined by dual energy X-ray absorptiometry (DEXA) using a LUNAR DPX densitometer at baseline. |
