Slide 1

﻿Knes 300 - Principles of Human Movement Course Objectives 1) Learn about the relationship between mechanical standards and moving bodies. 2) Apply your insight into these mechanical standards to surely understood aptitudes. Why investigate development? - Minimize harm, boost execution, enhance method.

Slide 2

Knes 300 - Principles of Human Movement Qualitative versus Quantitative Approaches Qualitative Description of value without the utilization of numbers. Quantitative Involving the utilization of numbers. Ex. Long hop - "That was a long bounce" versus the hop was 18 feet long

Slide 4

Qualitative versus Quantitative Descriptors Qualitative does not signify 'general'. A man strolling down the road may likewise be expressed 'a man is strolling gradually, gives off an impression of being inclining to one side, and is bearing weight on his correct leg for as short a period as would be prudent'. Both Q and Q are imperative in the biomechanical examination of human development and keeping in mind that specialists depend intensely on quantitative procedures, clinicians, mentors, and educators or physical exercises routinely utilize subjective perceptions of their patients, competitors, or understudies to plan feelings or give prompt.

Slide 5

Biomechanics The science including the investigation of natural frameworks from a mechanical viewpoint. Statics and Dynamics are two noteworthy sub-branches of mechanics. Statics is the investigation of frameworks in a condition of steady movement (very still or consistent speed). Progression is the investigation of frameworks in which increasing speed is available. Kinematics - depicts the presence of movement. Energy - the investigation of powers related with movement (since F=ma then increasing speed is imperative variable in dynamic examinations).

Slide 7

Chapter 1 - Sport Mechanics Mechanical Principles Basic decides that administer a competitor's activities. Ex. - Diver and gravity - ideal flight way -Wrestlers helped by gravity while getting adversary reeling -Ski jumpers utilizing air resistance

Slide 8

Chapter 1 - Sport Mechanics Technique -Patterns and arrangement of developments that the competitors use to play out a game aptitude. - Certain games incorporate a solitary ability, for example, plate tossing while tennis incorporates forehands, strikes, serves and so on - Each aptitude has a particular target that with "great" system might be accomplished with the most elevated level of productivity and achievement.

Slide 9

Chapter 1 - Sport Mechanics Traditional preparing strategies - Many mentors competitors still take after old, customary techniques in their workouts. - Trial and blunder techniques show an absence of comprehension of mechanical standards. - Copying title holders neglect contrasts in physical make-up, preparing and development. - Analyze exhibitions and show development designs that create effective system prompting to better exhibitions.

Slide 10

Chapter 1 - Sport Mechanics How to utilize this data - Learn to watch, break down, and remedy blunders in execution. - Assess the adequacy of developments in game gear. - Assess preparing techniques for potential wellbeing issues. - Assess the estimation of developments in the ways wear abilities are performed. - Know what's in store from various body sorts and diverse levels of development.

Chapter 2 - Starting with Basics Body weight Mass Inertia Speed, Velocity and Acceleration Gravity Force Vectors Projectiles

Slide 12

Chapter 2 - Starting with Basics Body weight -Newton's third law expresses that "For each activity there exists an equivalent AND inverse response" -Body's mass pulls on the earth and the world's mass pulls on the body. Scale perusing mirrors this common maneuvering considering the world's gravitational force. The world's gravitational force shifts as indicated by area (the further AWAY from the focal point of the earth, the littler the gravitational draw - the less you weigh).

Acceleration at Sea Level by Latitude

Slide 14

Chapter 2 - Starting with Basics Mass - All questions that have substance or matter have mass. - The human body is made out of bones, muscles, fat, tissues and liquids all of which are substance or matter and have mass. - A heavyweight wrestler has more mass than a tumbler bringing about more noteworthy fascination between the earth and the wrestler than between the earth and the athlete.

Slide 15

Chapter 2 - Starting with Basics Inertia - Resistance to activity or to change. - The sought of a question keep doing whatever it's doing - notwithstanding when it's moving. - All articles need to stay still, however in the event that a constrain moves them, then they need to keep moving in a similar bearing at a consistent speed.

Slide 16

Chapter 2 - Starting with Basics Distance Total ground secured or voyaged. A scalar. Removal As the crow flies - A straight line between the start and the end. Measured in cm, m, km. A vector Speed Distance separated by time. 100 miles went in two hours normal 50 mph. Speed Displacement isolated by time. 100 meters south separated by 10 seconds parallel 10 meters for every second in the south bearing.

Slide 17

Chapter 2 - Starting with Basics Speed, Velocity and Acceleration - A sprinter running the 100 m in 10 sec has a normal speed of 10 m/s or ~ 22 mph. This normal speed demonstrates that the sprinter more likely than not been going speedier and slower on occasion to normal the 22. - Velocity is a more exact depiction of speed - Giving it heading. In this manner it incorporates both speed and course - 20 mph due south. - The rate at which speed changes is named quickening. It might be sure or negative.

Slide 18

Chapter 2 - Starting with Basics Gravity -It is steady and it quickens falling bodies at a rate of 32 feet for every second every second or 9.8 meters for each second every second. - It influences execution on the grounds that the impacts of gravity change the further you are from the inside or center of the earth. - Ex. Mexico versus Moscow separations (rises and equator).

Slide 19

Chapter 2 - Starting with Basics Center of Gravity -The world's gravitational draw on the competitor is amassed at the competitor's focal point of gravity . - It speaks to the focal point of how the mass is dispersed from make a beeline for toes. Muscle and bone are more thick and accordingly have more mass squashed into the space they possess and in this manner the earth pulls more on those parts. - Ex. Guys higher machine gear-piece then females (hips) -Cog changes as appendages move and can be outside the body.

Slide 20

Chapter 2 - Starting with Basics Force -A push or a draw that progressions or tends to change the condition of movement of a competitor or protest. Compel vector - alludes to when the heading and measure of drive is known.

Slide 25

Motion Linear Rectilinear (skydiver, putt on level ground) Curvilinear (explanatory direction, cannonball) Angular (Rotary) Rotates around a pivot (wheels, turn jumps, joints, curveballs) General Combination of straight and rakish (sprinting)

Slide 26

Projectile Motion To build the flat separation (range) of a shot you have to consider: The speed at discharge The edge at discharge The stature at discharge

Slide 28

Chapter 2 - Starting with Basics Newton's Laws - Law of Inertia - a body will stay very still or keep on moving at a consistent speed unless followed up on by an outside compel. - Law of Acceleration - the speeding up of a protest is straightforwardly corresponding to the drive bringing on it, it is in an indistinguishable heading from the compel and it is contrarily relative to its mass. - Law of Reaction - for each activity there exists an equivalent and inverse response.

Slide 29

Chapter 3 - Getting a Move On Action - Reaction Momentum Impulse Work Energy Rebound Friction

Slide 30

Chapter 3 - Getting a Move On Action - Reaction This again is alluding to Newton's third (Law of Reaction). Ex. Sprinter pushing against the squares and the earth pushing back on the connected piece to impel the sprinter forward. The constrain delivered by the sprinter's muscles defeat idleness and she quickens. This speeding up is corresponding to how much drive she applies the time period over which it is connected, and it is contrarily relative to her mass.

Slide 31

Chapter 3 - Getting a Move On Momentum A moving competitor/question is a case of mass moving. Since a specific measure of mass is moving we allude to this as the an/o force . It depicts the amount of movement that happens. To expand force the an/o needs to increment either its mass or its speed or both. Vital in games that have crashes and effect - football, knocking down some pins, billiards. Increment mass by putting on muscle to build power and speed. Auto collisions specialists recreate crash scenes by figuring out which auto had more noteworthy force.

Slide 32

Momentum Testing the new Armed Forces obstructions... Every now and then somebody asks what the solid boundaries are before controlled and secure buildings.  When informed that the hindrances will stop movement, even trucks, from approac
