Fatigue01:21

Fatigue

978
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Fractures: Bone Repair01:27

Fractures: Bone Repair

6.4K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bone Disorders01:29

Bone Disorders

6.0K
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...

Stress-Strain Diagram - Brittle Materials01:24

Stress-Strain Diagram - Brittle Materials

4.8K
Brittle materials, including glass, cast iron, and stone, exhibit unique characteristics. They fracture without considerable change in their elongation rate, indicating that their breaking and ultimate strength are equivalent. Such materials also show lower strain levels at the point of rupture. The failure in brittle materials predominantly results from normal stresses, as evidenced by the rupture created along a surface perpendicular to the applied load. These materials do not display...

Thermal Stress01:09

Thermal Stress

3.5K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.2K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

    Area of Science:

    • Sports Medicine
    • Orthopedics
    • Exercise Physiology

    Background:

    • Stress fractures are common injuries in athletes.
    • University athletes, particularly freshmen, are susceptible to these injuries.
    • Training modifications can increase the risk of stress fractures.

    Purpose of the Study:

    • To investigate the incidence and risk factors of stress fractures in university athletes.
    • To identify patterns in training changes and symptom onset.
    • To determine the delay in seeking medical care for stress fractures.

    Main Methods:

    • Retrospective analysis of stress fracture cases over three years at a major university.
    • Data collection on athlete demographics, training history, and injury timelines.
    • Calculation of annual incidence rates and analysis of contributing factors.

    Main Results:

    • An annual incidence of 1.9% for stress fractures among university athletes.
    • Sixty-seven percent of stress fractures occurred in freshmen athletes.
    • Eighty-six percent of injuries followed abrupt training changes, with symptoms appearing 4.5 weeks later.
    • Athletes delayed seeking medical care by an average of 3.5 weeks.

    Conclusions:

    • Freshmen athletes are at a significantly higher risk for stress fractures.
    • Sudden alterations in training regimens are a primary cause of these injuries.
    • Emphasizes the need for vigilant monitoring of freshman training programs and prompt medical evaluation for suspected stress fractures.
