Here, latest syllabus of CBSE Syllabus for Class 12 Physical Education (Code No. The force acting along two surfaces in contact which opposes the motion of one body over the other is called the force of friction. Acrodynamics: The term acrodynamics is a combination of two Greek words- Aerios + Dynamics. Always warm up adequately by performing arm circles to avoid injuring your rotator cuff, while performing shoulder exercises. An axis is a straight line around which an object rotates. Deltoid, biceps, triceps are also involved in throwing a javelin in athletics. That is why it is important to train properly to improve your hops if you are not among that group.

PE teachers, coaches, and athletes are “biomechanists” but they think of biomechanics unconsciously. 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). Dance When a dancer leaps, he/she only stays in the air for a short amount of time because air resistance and gravity works against them. Like our quads, our calf muscles can be strengthened by doing squats. Hamstrings and Gluteus Maximus A plane is an imaginary flat surface along which a movement takes place. Calves Hamstrings: As you move forward, the action switches to your hamstrings, the muscles at the back of your thigh muscles. It is formed by the intersection of frontal and horizontal plane.

Effects of Air Resistance As the speed of an object increases, air resistance has a greater retarding effect. This line is known as axis of rotation. Every movement takes place, in one plane and around one axis. Though many anatomists see the calf muscle to be a single muscle (triceps surae), most say that it is a muscle group, like our quads and hip flexors. Streamlining Friction due to air is reduced by streamlining the shape of the body. You activate your hamstrings through hip extension and knee flexion.
