Summary
Current interval throwing programs (ITPs) for baseball pitchers lack consistent progression. A new computational model-based ITP ensures gradual workload increases, reducing injury risk during rehabilitation and optimizing return to play.
Area of Science:
- Sports Medicine
- Biomechanics
- Rehabilitation Science
Background:
- Lack of consensus exists regarding effective interval throwing programs (ITPs) for injured baseball pitchers.
- Current ITPs' throwing workload progression is not well understood.
Purpose of the Study:
- Evaluate three common ITPs for controlled, graduated throwing load increases.
- Develop a novel ITP with steady, predictable training load progression.
Main Methods:
- Analyzed three ITPs, calculating elbow varus torque and acute:chronic workload ratio (ACWR).
- Modeled workload progression and devised a new ITP using computational methods for gradual ACWR increase.
Main Results:
- ITPs showed varied throwing progression, with ACWR frequently falling outside the safe range (0.7-1.3).
- A novel 146-day ITP was designed with consistent ACWR, avoiding unsafe spikes.
Conclusions:
- Existing ITPs for baseball pitcher rehabilitation demonstrate inconsistent load progression.
- Computational modeling can create ITPs with incremental workload increases, aiding recovery and return to competition.

01:20Projectile Motion
15.3K
An object thrown in the air follows a parabolic path under the influence of Earth's gravitational force. The motion of such an object is called projectile motion, and the object itself a projectile. The parabolic path followed by the projectile is called the trajectory. Some common examples of projectile motion are the launching of fireworks, a golf ball in the air, meteors entering the Earth's atmosphere, and the firing of bullets.

01:18Projectile Motion: Example
9.7K
The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw their javelin in such a way that it travels as far as possible. The javelin thrower takes a short run-up to increase the initial speed of the javelin. The range of a projectile is at its maximum at a 45° angle so javelin throwers try to angle their throw as close to 45° as possible.

01:17Force and Momentum
15.9K
Force and momentum are intimately related. Force acting over time can change momentum, and Newton's second law of motion can be stated in its most broadly applicable form in terms of momentum. Momentum can be applied to systems where the mass is changing, such as rockets, as well as to systems of constant mass. Also, momentum continues to be a key concept in the study of atomic and subatomic particles in quantum mechanics. One can consider systems with varying mass in some detail; however,...

3.9K
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Projectile motion is commonly observed in our day-to-day life. For example, a basketball thrown by a player, an arrow shot from a bow, and kids jumping into the pool, all undergo projectile motion.
Any projectile motion problem can be solved by using the following strategy:

01:25Interpreting Run Charts
101
Run charts, essentially line graphs plotted over time, serve as fundamental yet effective tools for process analysis. They chronicle data sequentially, facilitating the identification of trends, shifts, or cyclical movements. This graphical representation is instrumental in determining whether a process is stable or exhibits signs of potential instability indicative of special cause variation. In the healthcare domain, run charts depict infection rates over time, enabling hospitals to monitor...
