Background: The assessment of the body composition provides information of main constituents of the human body and allows to differentiate between genders and ethnic or to assess changes with age, growth, physical activity, diet and disease. This study shows the evolution of the body compartments, its distribution, and the age and gender related changes in sedentary white people.Methods: A total of 1136 healthy subjects from Madrid and Castilla-La Mancha Regions (Spain) were recruited and divided into 16 groups according to age. Body compartments (fat mass, lean mass and bone mass) measures were obtained from dual energy X-ray absorptiometry (DXA) scans of all subjects. Total and regional (trunk, arms and legs) body composition were evaluated. Statistical analyses were performed using the statistical and data management package SPSS for Windows. Results:In males, Total body fat mass increased from birth through 30 years of age. In females, total body fat mass increased from birth through 20 years of age. The age-adjusted evolutional patterns of trunk fat mass showed genderrelated differences. In males, trunk fat mass increased to the age of 55. In females, increased to the age of 70. Males registered larger central fat deposits. There were gender differences for total lean body mass in all age groups except for the 6-10 year age group. Values were in all cases higher for males. Total bone mineral content shows significant gender differences form birth. Females reach a peak in bone mass earlier than males. Conclusion:Contrary to males, females showed from early infancy a smaller proportion of muscle mass and a higher proportion of body fat (from the age of 10), with fat deposits being mostly peripheral. The muscular body component in females is subject to minimal variations during adult age. Bone mass shows significant gender differences between 16 and 70 years of age; bone mass values were higher in males. DXA makes it possible to detect differences in body compartments during the life cycle, as well as it shows clear differences between males and females at any age and in different races or population groups. first techniques used and intended to measure body fat are fundamentally anthropometry and hydrodensitometry. Based on the body's electric conductance, bioelectrical impedance is used, but the possibility of measuring the absorption of energy particles by tissues has given way to absorptiometry techniques, first using an isotopic and then a radiological source. Currently, the advantages offered by dual energy X-ray absorptiometry (DXA) make it the most appropriate and widely-used technique, for measuring body composition in individuals of different ages and genders [3]. Keywords:DXAThis technique was used initially for the determination of bone mass (bone mineral content in gram (g) and bone mineral density in gram per square centimeter (g/cm 2 ). The bone mineral content and the soft tissue mass are computed on the basis of the attenuation of the energy of the two X-ray beams, making it possible t...

“…and LTO, H3 = generated peak net hip power between LHS and RHS. have higher amounts of subcutaneous fat (Bazzocchi et al, 2012). Heteroscedasticity of a mixed group of men and women could thus have affected the typical error in measurement and minimal detectable change (Haley & Fragala-Pinkham, 2006).…”

OBJECTIVE:To determine the reliability of the measurement of net joint power during repeated gait measurements within one day and between two different measurement days. METHODS: Thirty able-bodied men who underwent repeated gait measurements within a day and between days participated in this research. An acceptable trial was one in which the participant complied with the range of walking speed 1.45 m/s ± 5%. Three-dimensional angles, angular velocities, net moments of force and net power for the ankle, knee and hip joints were determined using external passive reflective markers, an 8-camera motion analysis system and two force plates. RESULTS: This study presents the patterns of the net power in the fundamental joints of the lower limbs in young healthy men at standard gait velocity. Intraclass correlation coefficients for net joint power measure reached values in the range of .70 to .89 on the first day, from .69 to .86 on the second day, and from .67 to .83 in total. CONCLUSION: The reliability of the measurement of the peak net joint power within one day and between the two measurement days was evaluated as satisfactory. The study provides the value of minimal detectable change for the peak net power of the lower limb in the sagittal plane during gait. The net joint power appears to be a reliable measure and could be used in practice.

“…DXA is an attractive opportunity in the study of muscle mass both at whole body and regional level and, according to the EWGSOP, it represents the preferred alternative method in research setting and clinical practice (17,54,55). Previous studies reported a good level of correlation between the measurements of skeletal muscle mass at lower limbs derived by DXA and those derived by CT and MRI, even if DXA tends to underestimate the extent of sarcopenia in comparison with the latter two techniques (92,93).…”

“…The role of DXA is central in the study of body composition (BC) thanks to its ability to differentiate FM, non-bone lean mass (LM) and BMC at both the regional and the whole-body level ( Figure 2) (49)(50)(51)(52)(53)(54)(55)(56)(57)(58)(59)(60). DXA relies on the use of two X-ray beams of different energy; the measurement of the "R value" is calculated as the ratio between the degree of attenuation of the lower energy and the higher energy beam.…”

Bone and muscle are two deeply interconnected organs and a strong relationship between them exists in their development and maintenance. The peak of both bone and muscle mass is achieved in early adulthood, followed by a progressive decline after the age of 40. The increase in life expectancy in developed countries resulted in an increase of degenerative diseases affecting the musculoskeletal system. Osteoporosis and sarcopenia represent a major cause of morbidity and mortality in the elderly population and are associated with a significant increase in healthcare costs. Several imaging techniques are currently available for the non-invasive investigation of bone and muscle mass and quality. Conventional radiology, dual energy X-ray absorptiometry (DXA), computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound often play a complementary role in the study of osteoporosis and sarcopenia, depicting different aspects of the same pathology. This paper presents the different imaging modalities currently used for the investigation of bone and muscle mass and quality in osteoporosis and sarcopenia with special emphasis on the clinical applications and limitations of each technique and with the intent to provide interesting insights into recent advances in the field of conventional imaging, novel high-resolution techniques and fracture risk.
