Summary
The new backstroke ledge (Omega OBL2) improves swimming starts by increasing head entry distance, leading to faster times and reduced variability. Swimmers should utilize this equipment for optimal performance.
Area of Science:
- Sports Science
- Biomechanics
- Swimming Performance
Background:
- FINA approved the Omega OBL2 backstroke ledge for competition.
- The performance impact of the OBL2 requires thorough evaluation.
Purpose of the Study:
- Compare backstroke start mechanics with and without the OBL2.
- Evaluate the OBL2's effect on key performance metrics.
Main Methods:
- Ten high-level swimmers performed starts with and without the OBL2.
- Force plates measured impulse and take-off parameters.
- Video analysis recorded entry distance and time to 10m.
Main Results:
- Starts with OBL2 resulted in 0.13s faster 10m times.
- OBL2 use decreased 10m time variability by 2.5%.
- Head entry distance increased by 0.14m with the OBL2.
Conclusions:
- The OBL2 enhances backstroke start performance primarily through increased head entry distance.
- Further research is needed to understand the biomechanical factors contributing to OBL2's benefits.
- Swimmers are advised to train and compete using the OBL2 for improved results.

01:11Buoyancy and Stability for Submerged and Floating Bodies
2.7K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

1.0K
Eccentric loading is a crucial concept in the study of structural engineering and mechanics, particularly when analyzing the stability and stress distribution in columns. Unlike centric loading, where the force is applied along the centroidal axis, causing uniform compression, eccentric loading occurs when a force is applied off-center. This off-center application introduces not only direct compressive stress but also bending stress, significantly influencing the column's behavior under...

01:22Cardiac Output II: Effect of Stroke Volume on Cardiac Output
3.8K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

When an object is placed in a fluid, it either floats or sinks. All objects in a fluid experience a buoyant force. For example, a metal ball sinks, while a rubber ball floats. Similarly, a submarine can sink and float by adjusting its buoyancy. The concept of buoyancy raises several interesting questions. For instance, where does this buoyant force come from? How much buoyant force is required to make an object sink or float? Do objects that sink get any support at all from the...
