What Does Warm up and Cool Down To Our Body??

 What is WARM UP?? A warm-up is a pre-exercise phase that usually consists of low- to moderate-intensity movements and activities. Its main goal is to progressively raise the body's core temperature, pulse rate, breathing rate, and blood supply to the muscles that are in use. The purpose of a warm-up is to get the body ready for more physically and psychologically taxing activities and exercise. Many exercises, including dynamic stretching, light aerobics, and sport-specific drills , are frequently used as part of a warm-up. These exercises improve brain activation, joint mobility, and muscular flexibility. A warm-up also makes it easier for oxygen to reach the muscles efficiently, which enhances energy metabolism and lowers the chance of injury. The warm-up phase facilitates the change from a state of inactivity or rest to one of physical exertion preparation. It is seen as a crucial part of any fitness programme, helping to enhance performance, reduce injuries, and promote gener

Hip adductors muscles in human body

The following muscles are called hip adductors. Adductor longus and adductor brevis Adductor Magnus Gracilis 1.        Adductor longus and adductor brevis -origin -anterior pubis -insertion- linea aspera on posterior femur Nerve supply- obturator(l3,4) Action- adduction of femur at the hip, assist flexion and medial rotation pf femur at the hip Palpation – adductor longs-prominent cord-like origin at media aspect of groin during active adduction of hip -adductor brevis-may attempt to palpate laterally to adductor longus origin on the pubis. Adductor longus forms the medial border of the femoral triangle. Adductor Magnus -origin- pubic ramus, ischial tuberosity, and ramus -insertion- linea aspera of posterior femur, adductor tubercle of medial femur -nerve supply- anterior -obturator nerve(l2,3,4)                             -posterior-sciatic nerve(l4,5,s1,2,3) Action- adduction of the femur at hip joint, assist medial rotation of femur at hip, anterior fibers assist flexion o

The longest muscle in the human body-sartorius

The sartorius is the longest muscle in the body .it is the most superficial thigh muscle and forms the lateral border of the femoral triangle.it is also called a tailored muscle. Origin- ·          Anterior superior iliac spine Insertion- ·          The upper  medial shaft of the tibia Nerve supply- ·          Femoral nerve(l2,3,4) Blood supply- ·          5-10 vessels originated from superior circumflex iliac, lateral femoral, deep femoral, descending geniculate and femoral artery Action – ·          Assist flexion,abduction,lateral rotagion of femur at hip joint ·          Assist flexion,medial rotation of knee(“tailor position”) Palpation- ·          Close to its origin,just below the anterior superior iliac spine,continuing diagonally across anterior pelvic area to its insertion during active flexion, abduction, and lateral rotation of the hip.   Its name is derived from the Latin word for tailor, sartor, to indicate its action of bringing the leg into a

Quadriceps group of muscles in human body

 the quadriceps muscle is consist of four muscle 1.    -rectus femoris -vastus intermedius -vastus medialis -vastus lateralis  These four large anterior thigh muscles insert below the knee and act to extend the knee joint. the three vast lie deep to the rectus femoris and two have their origins on the posterior femur. the rectus femoris originates on the pelvis and thereby can act to flex the hip. 1.rectus femoris Origin -long head: anterior inferior iliac spine                short head: upper margin of the acetabulum Insertion -patella and via patellar ligament to tibial tuberosity Nerve supply -femoral nerve (l2,3,4) Blood supply -lateral femoral circumflex artery Action -Extention of knee                assist flexion of femur at hip The palpation-anterior surface of the thigh during active knee extension The Rectus femoris is the only muscle in the quadriceps group that crosses both the hip and knee joints. its combined action is seen as the leg is brought

TENSOR FASICIAE LATAE MUSCLE IN THE HUMAN BODY

 THE TENSOR FASCIA LATAE IS A MUSCLE OF THE THIGH LOCATED IN THE LATERAL ASPECT OF THE THIGH. TENSOR FASCIA LATAE IS A FUSIFORM MUSCLE AND TOGETHER WITH GLUTEAL MAXIMUS IT ACTS ON THE ILIOTIBIAL BAND AND   IS CONTINUOUS WITH ILIOTIBIAL TRACT AND ATTACHES TO THE TIBIA. ORIGIN:  ILIAC CREST(POSTERIOR TO ANTERIOR SUPERIOR ILIAC SPINE) INSERTION:  ILIOTIBIAL TRACT (WHICH CONTINUES TO ATTACH TO THE LATERAL CONDYLE PF THE TIBIA) NERVE SUPPLY:  SUPERIOR GLUTEAL NERVE BLOOD SUPPLY: PRIMARILY LATERAL CIRCUMFLEX FEMORAL ARTERY,SUPERIOR GLUTEAL ARTERY ACTION:  PREVENTS COLLAPSE OF EXTENDED KNEE IN AMBULATION,ASSIST ABDUCTION,MEDIAL ROTATION,FLEXION OF FEMUR AT HIP AND EXTENSION OF KNEE. PALPATION: BELOW SUPERIOR ILIAC SPINE ON ANTERIOR PELVIS (AT A LEVEL OF GREATER TROCHANTER)DURING ACTIVE HIP ABDUCTION. THIS MUSCLE BRACES THE KNEE WHEN WALKING. ALSO KNOWN AS ILIOTIBIAL BAND(ITB).  

Gluteue medius muscle in human body

The Gluteus medius muscle is located in the posterior hip.it is a large fan-shaped muscle. muscle belongs to the gluteal region. Gluteue medius muscle in the human body Origin:  iliac crest, ilium between superior and middle gluteal lines Insertion: lateral the aspect of greater trochanter of the tibia Nerve supply:  superior gluteal nerve(l4,5,s1) Blood supply: superficial and deep branches of the superior gluteal artery Action:  hip abduction,  medial rotation of femur at the hip joint(anterior fibers) palpation of the muscle: lateral the aspect of hip between the iliac crest and greater trochanter during active hip abduction.  when standing on one foot, this muscle contracts on that side to stabilize the pelvis and prevent it from tilting to the unsupported side .alternate contraction of these muscles occurs in walking. Paralysis of this muscle on one side results in the “gluteal medius limp "the pelvis tilt towards the uninvolved side in walking.

GLUTEUS MAXIMUS MUSCLE IN HUMAN BODY

Gluteus  word is mostly used for Power, as in going  Upstairs, Rising from a sitting  position, climbing or running rather than walking. Gluteus Maximus is the primary extensor muscle of the hip.it is the outermost of the three gluteal muscles and it makes up a large part of the shape and appearance of each side of the hips. Origin:  superior gluteal line of ilium , Posterior sacrum, Lumbar fascia Insertion:   Greater trochanter(gluteal tuberosity)of femur, iliotibial tract    Nerve supply: Inferior gluteal nerve(L5,S1,2) Blood supply: MUSCULAR BRANCH OF THE INFERIOR GLUTEAL AND SUPERIOR GLUTEAL ARTERIES, The branches of the internal iliac artery. Action: Extention of the femur at the hip joint, lateral rotation of the extended hip.  Similar to other lower extremity muscles, the gluteus Maximus can move the femur against the pelvis(hip Extention)
