Summary
Stronger leg extensor muscles correlate with less body sway in males. This suggests that muscle strengthening exercises may improve balance and reduce sway in men.
Area of Science:
- Biomechanics
- Human Physiology
Background:
- Maintaining balance is crucial for daily activities and preventing falls.
- Leg extensor strength is a key component of postural stability.
Purpose of the Study:
- To investigate the relationship between leg extensor torque and the degree of body sway.
- To explore potential sex-based differences in this correlation.
Main Methods:
- Recruited 31 males and 22 females healthy adults.
- Measured leg extensor torque using a Strength Ergo 240.
- Assessed the degree of sway with a body pressure measurement system.
Main Results:
- A significant negative correlation was found between leg extensor torque and the degree of sway in males.
- No significant correlation was reported for females (implied).
Conclusions:
- Increased leg extensor torque is associated with reduced body sway in males.
- Therapeutic interventions focusing on muscle strengthening may enhance balance and reduce sway in men.

20.0K
Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as when pressing the accelerator in a car, which causes the engine to apply additional torque on the drivetrain. Here, we define torque and provide a framework to create an equation to calculate torque for a rigid body with fixed-axis rotation.
Torque can be considered as the rotational counterpart to force. Since forces change the translational...

01:13Angle of Twist - Elastic Range
590
Consider a cylindrical shaft with a length denoted by L and a consistent cross-sectional radius referred to as r. This shaft undergoes a torque at the free end. The highest shearing strain within the shaft is directly proportional to the twist angle and the radial distance from the shaft axis. When the shaft behaves elastically, this shearing strain can be articulated using variables such as the applied torque, radial distance, the polar moment of inertia, and the modulus of rigidity. By...

1.1K
Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium. Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and...

01:13Angle of Twist: Problem Solving
601
An electric motor applies a torque of 700 N·m to an aluminum shaft, triggering a stable rotation. Two pulleys, B and C, are subjected to torques of 300 N·m and 400 N·m, respectively. The modulus of rigidity is provided as 25 GPa. With the knowledge of the length and diameter of each segment, the twist angle between the two pulleys can be computed. First, a section cut is made between pulleys B and C, and the cut cross-section is analyzed using a free-body diagram. Given that the torque...

01:10Residual Stresses in Circular Shafts
407
In materials that exhibit elastic and plastic behavior, known as elastoplastic materials, residual stresses can accumulate when these materials experience plastic deformation. This deformation arises from either high levels of shearing stress or significant strains. Residual stresses are internal stresses that persist within a material after removing the external force causing deformation. This phenomenon is demonstrated when observing the behavior of a shaft under torque; notably, the...

01:09Torsional Pendulum
6.6K
A torsional pendulum involves the oscillation of a rigid body in which the restoring force is provided by the torsion in the string from which the rigid body is suspended. Ideally, the string should be massless; practically, its mass is much smaller than the rigid body's mass and is neglected.
As long as the rigid body's angular displacement is small, its oscillation can be modeled as a linear angular oscillation. The amplitude of the oscillation is an angle. The role of mass is played...
