Actin Treadmilling01:18

Actin Treadmilling

9.7K
Actin filaments undergo polymerization and depolymerization from either end. The polymerization and depolymerization rates depend on the cytosolic concentration of free G-actins. The polymerization rate is generally higher at the plus or barbed end, while the depolymerization rate is higher at the minus or pointed end. At a steady state, critical concentration describes the concentration of free G-actin monomers at which the polymerization rate at the plus end is equal to that of the...

Fixed Action Patterns01:06

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Classification of Skeletal Muscle Fibers01:48

Classification of Skeletal Muscle Fibers

59.5K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Oxygen Requirements and Growth Patterns01:29

Oxygen Requirements and Growth Patterns

1.4K
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

Muscles of the Eye01:20

Muscles of the Eye

4.4K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Area of Science:

  • Biomechanics
  • Exercise Physiology
  • Kinesiology

Background:

  • Self-propelled treadmills offer a low-cost alternative for exercise.
  • Understanding the biomechanical and muscular demands of treadmill use is crucial for effective training.

Purpose of the Study:

  • To investigate the muscular requirements during self-propelled treadmill walking.
  • To evaluate the potential of self-propelled treadmills for fitness training.

Main Methods:

  • Eleven healthy college students participated.
  • Gait analysis, including step length and lower extremity muscle activation, was performed.
  • Three walking conditions were compared: over-ground, self-propelled treadmill at self-selected speed, and self-propelled treadmill at a comparable speed to over-ground walking.

Main Results:

  • Step length was significantly shorter on the self-propelled treadmill compared to over-ground walking.
  • Muscle activation patterns and spatiotemporal gait parameters differed across conditions.
  • Higher muscular demands were observed at the hip and knee during heel-strike on the self-propelled treadmill.

Conclusions:

  • Self-propelled treadmill walking, especially at faster speeds and with incline, increases lower extremity extensor activation during heel-strike.
  • These findings indicate that self-propelled treadmills can serve as a valuable tool for targeted muscle training.
