An Old Problem: Aging and Skeletal-Muscle-Strain Injury
Journal of Sport Rehabilitation
|January 18, 2017
Summary
Biological aging impairs skeletal muscle repair after strain injuries. Understanding these age-related changes is key to developing better prevention and treatment strategies for muscle injuries in older adults.
Area of Science:
- Gerontology
- Skeletal Muscle Physiology
- Biomedical Science
Background:
- Biological aging, not just chronological, significantly impacts quality of life and functional independence.
- Skeletal muscle injuries are common, but the effects of aging on injury induction, healing, and recovery remain unclear.
- Aging impairs the response and recovery of skeletal muscle to contraction-induced injuries, with no scientific consensus on the exact mechanisms.
Purpose of the Study:
- To investigate how aging influences skeletal muscle's response to strain injury.
- To clarify the mechanisms behind age-related impairments in skeletal muscle healing and recovery.
- To highlight the importance of appropriate muscle injury models for physiologically relevant research.
Main Methods:
- Focus on stretch-shortening contractions, a common form of muscle movement.
- Analysis of age-related changes in skeletal muscle injury and repair processes.
- Consideration of various investigative approaches and research paradigms.
Main Results:
- Aging impairs the secondary injury response and recovery of skeletal muscle after contraction-induced injuries.
- The exact mechanisms responsible for age-related deficits in muscle repair are not yet fully understood.
- Stretch-shortening contractions are highlighted as a relevant model for studying muscle injury in aging.
Conclusions:
- Understanding age-related changes in skeletal muscle injury is crucial for clinical prevention and treatment strategies.
- Maintaining skeletal muscle health in aging can improve injury thresholds, reduce incidence, and speed recovery.
- Improved understanding may lessen the overall economic burden associated with age-related muscle injuries.

2.1K
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...

01:19The Effect of Aging on Tissues
4.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:29Bone Disorders
5.8K
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...

01:26Cross-bridge Cycle
123.9K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

01:24Muscle Recovery and Fatigue
4.6K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:29Relaxation of Skeletal Muscles
6.4K
The period of muscle contraction primarily influences the duration of stimulation at the neuromuscular junction (NMJ), the presence of free calcium ions in the sarcoplasm, and the availability of energy or ATP to support contractions.
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....
