Let us now check the Syllabus with topics to be covered with exam pattern. 1 Mark Questions Answer : An axis is an imaginary line about which the body or limb rotates. It is formed by the intersection of sagittal and frontal plane. They consist of the psoas major and iliacus, and because of this, they are often referred to as the iliopsoas. COVID-19 has forced faculty, staff and students to change from in person classes, to hybrid, to fully remote.

Projectile and Factors Affecting Projectile Trajectory Elaborate the term Biomechanics.Ans. Hip Flexors c) Abduction means moving a part away from the midline (lifting the upper limb horizontally to form a right angle with the side of the body)) d) Adduction means moving a part towards the midline ( returning the upper limb from the horizontal position to the side of the body). There is no change made in the syllabus and exam pattern. (i) Static Friction The opposing force that comes into plc when one body tends to move over the another surface but the actual motion has not yet red (ii) Limiting Friction Limiting friction is the maximum of thing force that comes into play when one body is just on the verge of moving over the surface of another body. Football players can slow down, stop or reverse the direction of other players depending upon how much force they can generate and in which direction. It passes straight through the top of the head down between feet. Biceps maintain a bent arm and help in swinging your arms back and forth while running.

To our right, the shortest muscle, the iliacus, begins on our pelvic crest (the iliac fossa) and stretches over to our thigh bone (femur). A lying leg raise is a good exercise to strengthen the hip flexors. * Friction * Mechanical Analysis of walking and Running. Acrodynamics: The term acrodynamics is a combination of two Greek words- Aerios + Dynamics. A tuck jump is a good exercise to work your calves because it is specific to jumping. Calf Muscles Eventually, gravity will act on the ball, pulling it down to the ground. The gluteus macimus is the largest of the gluteal muscles. CHAPTER 7 – Physiology and Injuries in Sports. In fact, jumping occurs in three stages. Search This Blog Chapter 10 - Kinesiology, Biomechanics and Sports Notes Class 12 CBSE Physical Education KINESIOLOGY, BIOMECHANICS AND SPORTS: IMPORTANT TERMS, CONCEPTS (STUDY MATERIAL) 1. Importance of Biomechanics in Physical Education ! lagged the area of contact between the surfaces, the greater is the force of friction. If you have any query regarding NCERT Physical Education Class 12 Notes Chapter 10 Kinesiology, Biomechanics and Sports, drop a comment below and we will get back to you at the earliest. The force acting along two surfaces in contact which opposes the motion of one body over the other is called the force of friction. The hamstrings are opposing muscles to the quadriceps and have an opposite function. Our hamstrings are made up of four muscle parts on the back of our thighs. A squat works the hamstrings, but you can place more emphasis on them by doing a lunge. Here we have given NCERT Physical Education Class 12 Notes Chapter 10 Kinesiology, Biomechanics and Sports. Among the best exercises for your abs are hanging leg raises and swiss ball crunch. The aroplanes are made with a sharp front to reduce friction. The soleus sits anterior, or in front of the gastrocnemius. Many sports require more friction and other need lesser friction. When the human body or an object is projected through space, three forces influence the course of flight, Friction Static Friction The opposing force that comes into play when one body tends to move over the another surface but the actual motion has yet not started is called static friction. A strong core facilitates the transfer of power from your lower body to your upper body, enabling your throws to benefit from the strength of your legs. Throwing Mechanical analysis of walking can be studied in two fieldsStance phaser: Stance phase is the time when the foot is on the ground. * Introduction to work, Power and Energy. Physical Education. They are categorised by movement type as follows. NCERT Solutions for Class 12 Physical Education in PDF file format updated for academic session 2020-2021, Important notes on Physical Education Class 12 (+2) and Important questions with answers in English Medium & Hindi Medium. Even if you wish to have an overview of a chapter, quick revision notes are here to do if for you. b) Frontal or Coronal plane: the frontal plane is also vertical and passes from left to right dividing the body into posterior to anterior halves. Rotation: Rotation is a form of movement in which a bone moves around a central axis without undergoing any displacement from the axis. PE teachers, coaches, and athletes are “biomechanists” but they think of biomechanics unconsciously. Effects of Air Resistance As the speed of an object increases, air resistance has a greater retarding effect. Today, biomechanics is playing a very important role in improving the performance of sportspersons. Unit VII Physiology & Injuries in Sports ... • Meaning and Importance of Biomechanics in Sports • Types of movements (Flexion, Extension, Abduction & Adduction) • Newton’s Law of Motion & its application in sports All parts get activated during the lowering phase and the explosive phase of a jump. Sagittal axis passes from front to back. a) Sagittal or Medial plane: The sagittal plane is a vertical plane passing from the rear to the fronty, dividing the body into left and right halves. Here we have given NCERT Physical Education Class 12 Notes Chapter 10 Kinesiology, Biomechanics and Sports. Biomechanics is the science that examines the internal and external forces acting on a human body and the NCERT Solutions for Class 12 Physical Education will provide you all topics of CBSE class 12 Physical Education syllabus we will explain all the solution in detail. Hamstrings The more we know about our body, the better we can protect it by treating it with care and avoiding injury. You activate your hamstrings through hip extension and knee flexion. Biomechanics and Sports Class 12 Like & Share the video. This action helps you release the ball with force and push it in the desired direction. Abdominals Soccer When a soccer ball is kicked into the air, gravity will pull it back to the ground. The iliopsoas are often the culprit behind severe hip pain. With a little knowledge, we can help prevent these injuries with the right equipment and by properly stretching our muscles before the run. Our calf muscles will allow us to flex our knee and planter flex our ankle. Sir Issac Newton made three laws of motion which are explained below. This line is known as axis of rotation. Increasing strength in our muscles apart from running can decrease our risk of injury and increase our speed. Among the most effective exercises for the quadriceps are the barbell step-up, barbell lunge and barbell squats, which also work your abdominal muscles. These two muscles work together to help our hips flex. These muscles helps you in pulling the leg back behind and give you strength to propel your body forward.

The various movements which fall under angular movements are described below: a) Flexion: Bending parts at a joint so that the angle between them decreases and parts come closer together (bending the lower limb at the knee). Deltoid, biceps, triceps are also involved in throwing a javelin in athletics. CBSE Useful Resources There are following types of axes of rotation: a) Sagittal axis: The sagittal axis passes horizontally from posterior to anterior. They work together to straighten our knees and bend our hips. Circumduction: Circumduction is that movement which takes place between the head of a bone and its articular cavity. During a jump, you perform hip flexion and knee extension, which both activate the quadriceps. Many implements like the discus are painted to reduce friction.
