Summary
High-load physical activity like gymnastics may improve bone health. Female gymnasts showed better trabecular bone structure in their tibias compared to non-athletes, indicating positive effects on weight-bearing bones.
Area of Science:
- Orthopedics
- Sports Medicine
- Bone Physiology
Background:
- Artistic gymnastics participation is linked to higher bone mineral density.
- The impact of gymnastics on weight-bearing bone's trabecular microarchitecture remains unclear.
Purpose of the Study:
- To investigate the trabecular microarchitecture of the proximal tibia in female collegiate gymnasts.
- To compare bone structure between gymnasts and matched controls.
Main Methods:
- High-resolution magnetic resonance imaging (MRI) was used to assess apparent bone volume to total volume (appBV/TV), trabecular number (appTb.N), thickness (appTb.Th), and separation (appTb.Sp).
- Dual-energy X-ray absorptiometry (DXA) measured areal bone mineral density (aBMD) and bone mineral content (BMC).
- Eight female gymnasts and eight matched controls were studied, with group differences analyzed using t-tests and Cohen's d.
Main Results:
- Gymnasts exhibited significantly higher appBV/TV and appTb.N, along with lower appTb.Sp, indicating a more robust trabecular structure.
- While gymnasts showed higher aBMD and BMC, these differences were not statistically significant.
- The observed differences in trabecular microarchitecture were statistically significant (p < 0.05).
Conclusions:
- High-load physical activity, exemplified by gymnastics, appears to positively influence weight-bearing bone's trabecular microarchitecture.
- These findings suggest that mechanical loading from activities like gymnastics can enhance bone quality beyond just bone density.

01:09Spongy Bone
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
