Exercise and Muscle Performance01:27

Exercise and Muscle Performance

2.1K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Elastin is Responsible for Tissue Elasticity01:12

Elastin is Responsible for Tissue Elasticity

2.8K
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.0K
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...

Isotonic and Isometric Muscle Contractions01:22

Isotonic and Isometric Muscle Contractions

5.7K
Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.
Isotonic contractions
Isotonic contractions occur when a muscle changes length while...

Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

3.1K
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...

Area of Science:

  • Sports Science
  • Biomedical Engineering
  • Orthopedics

Background:

  • Tendons are crucial for force transmission between muscles and bones.
  • Chronic resistance training improves tendon stiffness and cross-sectional area.
  • Eccentric training may induce greater tendon adaptations due to higher potential loads.

Purpose of the Study:

  • To review the effects of eccentric exercise on healthy tendon tissue.
  • To compare eccentric training with other exercise modalities for tendon adaptation.
  • To explore eccentric training's potential for counteracting age-related tendon changes.

Main Methods:

  • Literature review of studies on eccentric exercise and tendon properties.
  • Comparison of adaptation responses between eccentric and other training types.
  • Analysis of eccentric training's applicability for older populations.

Main Results:

  • Eccentric exercise can modify tendon properties, including stiffness and Young's modulus.
  • While overall adaptation may be similar across contraction types, eccentric training offers unique benefits.
  • Eccentric training shows promise in mitigating age-related tendon degeneration.

Conclusions:

  • Eccentric exercise is effective in enhancing tendon mechanical properties.
  • Eccentric training may be a suitable modality for preserving tendon health in aging individuals.
  • The lower mechanical demands of eccentric contractions make them accessible for the elderly population.
