Summary
The mechanical work of the foot's longitudinal arch is linked to energy expenditure during running. Strengthening the arch may improve running efficiency and optimize energy use.
Area of Science:
- Biomechanics
- Sports Science
- Human Physiology
Background:
- The medial longitudinal arch (MLA) of the foot is crucial for energy storage and release during locomotion.
- Understanding the dynamic mechanical behavior of the MLA and its relation to energy expenditure during running is limited.
Purpose of the Study:
- To investigate the association between changes in the mechanical work of the MLA and energy expenditure during prolonged running.
Main Methods:
- 16 male athletes underwent a 60-minute treadmill run at 10 km/h.
- Biomechanical data (longitudinal arch work) and metabolic data (oxygen consumption, carbon dioxide production, heart rate) were collected simultaneously.
Main Results:
- Positive arch work and metabolic variables increased and stabilized within the first 10 minutes.
- Both positive and negative arch work correlated significantly with energy expenditure (p < 0.05).
- The dynamic function of the MLA is linked to metabolic demand during exercise.
Conclusions:
- The MLA plays a critical role in regulating energy expenditure during running.
- Strengthening the MLA and incorporating stretching may enhance running efficiency by optimizing energy utilization.

01:10Work and Energy for Variable Forces
3.9K
When an object is acted upon by a variable force, the amount of work done and the change in energy of the object can be more complex to calculate compared to when a constant force is applied. Work is the product of force and displacement, while energy is the capacity of a system to do work. When a constant force is applied to an object, the work done can be calculated as the product of the force and the distance moved in the direction of the force. However, when a variable force is applied, the...

Strain energy is a fundamental concept in the field of materials science and structural engineering, describing the energy absorbed by a material or structure when it is deformed under load.
Consider a rod that is fixed at one end and subjected to an axial force at the free end. This axial force induces stress within the rod, leading to its elongation. As the axial force increases, so does the elongation of the rod, illustrating a direct relationship between the force applied and the resulting...

The dynamics of a mechanical system can be easily understood by interpreting a potential energy diagram. Since energy is a scalar quantity, the interpretation of the dynamics of the system becomes even simpler.
Take the example of a skater on a parabolic ramp. The potential energy at different points along the ramp will be proportional to the height of the ramp, which varies quadratically with the horizontal position on the ramp. As the skater moves down the ramp from the highest position,...

01:19Impact Loading

Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.

Energy diagrams are important to understand the dynamics of a system. The topology of an energy diagram helps illustrate the equilibrium points of the system.
The point in the energy diagram at which the system’s potential energy is the lowest is known as the local minima. The system tends to stay in this position indefinitely unless acted upon by a net force. The slope of the potential energy diagram at the local minima is zero, indicating that zero net force is acting on the system. The...

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
