Summary
Elementary school badminton players exhibit greater shoulder internal rotation (IR) and total range of motion (TROM) than university players, with less TROM loss. Sex differences in shoulder ROM were also observed in university players.
Area of Science:
- Sports Medicine
- Biomechanics
- Orthopedics
Background:
- Understanding shoulder function in badminton players is crucial for developing effective injury prevention programs.
- Limited research exists on shoulder function parameters specific to badminton players, especially when controlling for age and sex.
Purpose of the Study:
- To investigate and compare shoulder range of motion (ROM) between elementary school-age and university badminton players.
- To identify age-related differences in shoulder internal rotation (IR), external rotation (ER), and total ROM (TROM).
Main Methods:
- A cross-sectional study was conducted involving 67 badminton players (ages 7-12 and 18-22) with no history of shoulder injury.
- Shoulder ROM, including IR, ER, and TROM, was measured in both dominant and non-dominant arms.
- Data were analyzed to compare ROM parameters between age groups and sexes.
Main Results:
- Elementary school players demonstrated significantly greater shoulder IR and TROM in both arms, and greater dominant ER compared to university players.
- Significant differences in IR and TROM were found between male and female university players.
- TROM loss was significantly smaller in elementary school players compared to university players.
Conclusions:
- Elementary school badminton players possess superior shoulder IR, TROM, and dominant ER, alongside reduced TROM loss, relative to university players.
- No significant sex-based differences in bilateral deficit for glenohumeral rotation were observed between the age groups.
- Findings highlight age-specific adaptations in shoulder function among badminton players, informing targeted training and injury prevention strategies.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:20Introduction to the Skeletal System
5.3K
The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:30Socioemotional Experience and Gender Development
22
Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
