Muscular Strength
The physical ability of an individual is influenced by his
or her muscle strength. Strong muscle will function efficiently. An efficient
muscle, will experience delayed exhaustion while performing high intensity
work. Having high muscle strength enables an individual to do more quality
daily life activities. Muscle strength is defined as the ability something
muscle or a group of muscles to overcome resistance to produce force (work).
The lungs increased ability to the optimum utilisation capacity will continue
and oxygen can be supplied to muscles to prevent fatigue. Muscle strength is
measured based on the maximum force produced from a movement or specific muscle
contraction. The strength of muscle is connected to muscle size, the type
muscle fibre, nervous system and one’s percentage of testosterone level. For
example, men can easily build more muscle strength compared to women because
the muscle size of men is larger and they have a higher percentage of
testosterone hormone.
The strength of muscle is the ability of the muscle to
overcome heavy burden or resistance. For example weightlifting, standing long
jump test, sergeant jump test and others. The strength of the muscle is very
important to achieve high performance in sports, contributing to the power to
perform certain task. Muscle strength is also needed in daily activities like
walking, running, lifting things and others.

Body Composition
The body composition of a person consists of fat and non-fat components. The total of both parts determine the weight and shape of a body. Human body build can be divided into three body types namely endomorph, mesomorph and ectomorph.
- Endomorph is a sturdy body structure because there are many fats accumulating beneath the skin. People with this body type are suitable for sports like weightlifting, throwing iron hammer and wrestling.
- Mesomorph is muscular body, strong with an attractive body structure. People with this body type are suitable for sprints and jumping events.
- Ectomorph has a thin and lanky frame because the body lacks fatty tissues under the layers of skin. Those with this type of body are suitable to become long distance runners, cross country athletes and basketball players.

Muscular Endurance
There are three components of activities directly related to muscles: muscular endurance, muscular strength and muscular power. Muscular endurance is the ability of a muscle or a group of muscles to sustain doing a work repetitively for a long time. Muscular endurance falls into two categories: static muscular endurance and dynamic muscular endurance.
Muscular endurance is measured based on the recurring muscle contractions against a resistance for an extended period of time. For example, activities to increase muscle's resistance include sit ups, push-ups and burpee exercise.

PHYSICAL FITNESS RELATED TO HEALTH
Cardiovascular Endurance
Cardiovascular endurance is the ability of the cardiovascular system to distribute oxygenated blood to working muscles and then excreting waste materials from the muscle. This phenomenon occurs continuously and for a long period of time. We could increase the system's effectiveness by doing physical activity. Cardiovascular system constitutes:
Heart capacity and blood circulation continues to function when somebody does work for a long period. Cardiovascular endurance is the most important component in human physiological profile and it involves aerobic and anaerobic endurance.

This phenomenon occurs continuously and for a long period of time. We could increase the system's effectiveness by doing physical activity. Cardiovascular system constitutes:
- Heart
Pump blood through pulmonary circulation and systemic system. - Lungs
Supply oxygen to the blood and excrete carbon dioxide from blood. - Artery and Vein Network
Artery network carries blood from the heart to the whole body, while vein carries blood from the entire body back to the heart.

Respiratory Distress Syndrome (RDS)
Respiratory Distress Syndrome (RDS)
What is Respiratory Distress Syndrome (RDS)?
Respiratory distress syndrome (RDS) in the newborn, also known as hyaline membrane disease, is a common complication seen in premature babies. Babies with this condition will develop breathing difficulty and may require intensive care management. RDS can be mild or severe, the severity and progression depend mainly on lung maturity.
10 facts on child health
10 facts on child health
A child's risk of dying is highest in the first month of life.
In the first month of life safe childbirth and effective neonatal care are essential. Preterm birth, birth asphyxia and infections cause most newborn deaths. Once children have reached one month of age, and up until the age of five years, the main causes of loss of life are pneumonia, diarrhoea, and malaria. Malnutrition contributes to more than one-third of all child deaths.Jan 28, 2013
