Explanation / Answer

Question 72

Answer is D (Actin and Myosin proteins)

The skeletal muscle tisuue consist cells are clled muscle fibers. The muscle fibers consist of different components such as nucleus, sarcolemma, sarcoplasm and myofibrils. The myofibrils are filaments like structure and located along muscle fiber.arranged parallel to each other.

These muscle fibers have two types of filament proteins that is thin filaments and thick filaments. thin filaments are called actin filaments and thick filaments are called myosin. These filaments partially overlapping or covering layres.

Question 73.

Answer is C (of mild and moderate discomfort)

The stretching of different body parts is one type of exercise. This type of stretching can improve the function of the body parts especilly. In improving the streching capacity intially stretch with minium force that should not cause pain.Every person hsve different streching capacity. Depending on that capacity stretch to the point of mild and moderate discomfort to get improvement in range of motion.

Question 74

Answer is D (B& C)

It is essential to determine the composion of the body because increased level of fat substnces increases the risk of different diseases such as diabetes and cardiovascular diseases. So this test is mainly concerned with determination of fat compartments of the human body and lean compartments of the human body. Before undergoing to this test should follow some guidelines such as do not drink alcohol before test , do not eat, drink water etc.

Question 75

Answer is E (Muscle biopsy)

the composition of body is mainly concerned witn determination of fat. the can be determined by different test that are

i. Anthropometry- basic method which can determine body mass, size, shape, Abdominal Circumference and Skinfolds test

ii. Body density- it can be determined by densitometry

iii.Dual-energy X-ray absorptiometry (DXA)

iv. Computed X-ray tomography (CT)

v. Bioelectrical impedance analysis- Determines total body water and fat free mass

other method that direct methods are total body water and total body counting and neutron activation

Question 76

Answer is D (all the above)

ISSA is the international sports sciences association. The aim of this to

improve the quality of training and provide high level of motivation

distingiuishes as professionals

it have five stages

i. developing yourself as professional

ii. collection of data

iii. instructions to dicovery tour etc.
