Curves Defined by Parametric Equations

Curves Defined by Parametric Equations

A baseball hit into the air follows a parabolic trajectory when air resistance is neglected. The motion can be described within a two-dimensional coordinate system, where both the horizontal displacement and vertical height are functions of time. Instead of expressing the trajectory as a single function of position, the motion is modeled using parametric equations: one function for the horizontal position and another for the vertical position as time progresses. Let the horizontal position be...

Motion of a Projectile

Motion of a Projectile

Projectile motion becomes evident when a player kicks the ball into the air. The launch angle, or the angle at which the ball is kicked, plays a crucial role in determining the trajectory of the projectile. As the ball soars through the air, influenced solely by gravity, its motion can be dissected into two independent velocity components: the horizontal and the vertical.
Horizontal motion, governed by the initial kick, maintains a constant velocity throughout the flight of the soccer ball.

Social Facilitation

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Projectile Motion

Projectile Motion

Projectile motion models the flight of an object launched into the air, such as a soccer ball kicked during a penalty, under the simplifying assumption that air resistance is negligible. When gravity is the only force, the object experiences a steady downward acceleration at all times. This single fact explains why projectile motion can be analyzed as two independent motions happening simultaneously: a horizontal motion that does not speed up or slow down, and a vertical motion that continually...

Projectile Motion

Projectile Motion

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.
When an object falls under gravity and has no horizontal...

Summary

Establishing a preinjury performance profile is crucial for objectively evaluating a pitcher's throwing shoulder function post-injury. This profile, including fastball velocity, accuracy, and endurance, aids in creating simulated games for rehabilitation assessment.

Area of Science:

Sports Medicine
Orthopedics
Biomechanics

Background:

Objective evaluation of throwing shoulder function post-injury requires preinjury performance data.
A simulated game based on preinjury profiles is ideal for comparison but often unavailable.
Performance profiles should encompass strength (fastball velocity), accuracy (fastball-for-strike percentage), and endurance (velocity decrease per inning).

Purpose of the Study:

To develop a representative performance profile for Major League Baseball (MLB) starting pitchers lacking preinjury data.
To establish parameters for a simulated baseball game to assess pitcher performance.
To provide a framework for evaluating throwing shoulder rehabilitation across all baseball levels.

Main Methods:

Collected data from 98 MLB starting pitchers from 1983-1985.
Logged 145,886 pitches across 486 games using a custom data form.
Utilized an IBM-360 computer for data entry and analysis.

Main Results:

A simulated game profile includes 6 1/3 + 1 1/3 innings with 15 + 2.4 pitches per inning.
Minimum 9-minute rest interval between innings is recommended.
Expect a 2% (1.5 mph) decrease in fastball velocity from innings 1-6, with a 64% fastball-for-strike percentage.

Conclusions:

The developed performance profile provides a baseline for pitchers without preinjury data.
The simulated game parameters offer a standardized method for performance evaluation.
The concept of preinjury performance profiles is applicable for assessing rehabilitation from youth leagues to professional baseball.
