“…Treadmill, resistance exercise, and bicycle ergometer are three main training exercises to prevent musculoskeletal system degeneration in the International Space Station (ISS) [21]. Astronauts spent approximately 2.5 h doing exercises every day, but bone loss and muscle atrophy still persisted [22,23]. In general, exercise countermeasures adopted in space to resist bone loss have had only limited success [21].…”

“…A scientific study indicated that a mechanical stimulus in the form of vibration, traveling from the sole of the foot through the skeleton, is anabolic for bone [41]. Studies have shown that current vibration devices induce beneficial increases in bone mineral density (BMD), although diminished functional loading has been shown to decrease bone quantity in the case of bed rest patients or astronauts under microgravity conditions [21][22][23][24]. In a recent study, Pichler et al suggested that it might be possible, through mechanical stimulation, to inhibit the activity of receptor activator of nuclear factor κB ligand (RANKL) through the RANKL/RANK/OPG system in bone modeling and remodeling [42].…”

Abstract:Musculoskeletal vibration stimulation is the topic chosen for this review. The aim is to discuss this interesting, but poorly analyzed topic in the current literature in order to explain and help readers to better understand the effects of vibration used as an exercise intervention and therapy for muscle, bone, and cartilage tissues. The use of vibration stimulation for enhancing athletic performance and therapeutic use is considered an important matter of medical biology that has developed in the last three decades. Current evidence suggests that vibration is effective in enhancing musculoskeletal strength and power capacity and improving physical conditions in patients with related disorders such as osteoporosis and osteoarthritis, although the mechanisms mediating these effects are still not well known.

“…Clinical observations [11,12,13] and plausible biological pathways [10] indicate that both lean and fat mass affect BMD. Astronauts under weightless conditions in space as well as patients confined to bed for a long period of time experience bone density loss [11,12,13]. In animal models, bone precursor cells fail to respond to factors that regulate their proliferation without mechanical loading [14].…”

Background/Aims: Childhood and adolescence are critical periods for bone growth. The independent association between lean and fat mass and indicators of bone health in children is not yet known. We aim to examine the association between each of lean and fat mass and indicators of bone health in 8- to 10-year-old prepubertal Caucasian children. Methods: We present a cross-sectional analysis of baseline data from the QUebec Adipose and Lifestyle InvesTigation in Youth (QUALITY) cohort which study the natural history of obesity. Study participants (n = 483) included prepubertal children aged 8-10 years and their biological parents. Whole-body bone mineral content (BMC, g), bone area (cm²), bone mineral density (BMD, g/cm²), lean mass (kg), and fat mass (kg) were measured by dual-energy X-ray absorptiometry. Data analyses include multiple linear regressions adjusted for potential confounding variables. Results: A 1-kg increase in lean mass was associated with 28.42 g, 19.88 cm², and 0.007 g/cm² increase in whole-body BMC, bone area and BMD respectively. A 1-kg increase in fat mass was associated with 9.32 g, 8.02 cm², and 0.002 g/cm² increase in whole-body BMC, bone area and BMD, respectively. Conclusion: Increasing lean mass in children may help optimize bone acquisition and prevent future osteoporosis.

“…Therefore, astronauts have been performing exercise countermeasures to prevent this undesirable adaptation on the ISS [10,16,17]. Aerobic exercise has been performed $ 5 h/wk at a moderate intensity and resistance exercise has been performed 3-6 days/wk.…”

“…Furthermore, experts suggest that it is better to gradually increase the work intensity to improve physical fitness levels. Astronauts on the International Space Station (ISS) have been performing exercises using a treadmill as countermeasures for muscle deterioration [10,16,17]. However walking exercise does not necessarily prevent atrophy of soleus muscle under these debilitating conditions.…”
