What is isotonic concentric contraction?

A concentric muscular contraction that exerts force while shortening in length.

What does isotonic eccentric contraction involve?

Producing force while lengthening.

What is motion analysis in biomechanics?

The study of kinematics (motion) and kinetics (force causing motion).

Define linear motion.

A body segment moves in a straight line, influenced by velocity, acceleration, and momentum.

What is the formula for calculating velocity?

Velocity (V) is calculated as V = D/T, where D is distance and T is time.

What is displacement in motion?

The straight line change in position with direction.

What does limb displacement refer to?

Movement of limbs through space during various activities, crucial for coordination and balance.

How is acceleration defined?

The rate of change of velocity over time.

What are the types of acceleration?

Positive (speeding up), Negative (deceleration), and Zero (constant velocity).

How does acceleration relate to athletic performance?

Faster acceleration leads to less reaction time, helping athletes reach top speed quicker.

What is momentum?

The product of mass and velocity (M = m x V).

How does greater momentum affect collisions?

It makes it harder to stop during a collision.

What is the World Health Organization's perspective on health in relation to SDGs?

They emphasize health as central to achieving Sustainable Development Goals (SDGs), focusing on health coverage and social determinants.

What are the Sustainable Development Goals (SDGs)?

17 global targets by the United Nations aimed at addressing global issues by 2030.

How are SDGs utilized in Australia?

They guide policies and programs in health, education, and environmental areas, addressing major concerns like inequality.

What is SDG 1 focused on?

Reducing poverty.

What does SDG 3 promote?

Improving health.

What is the focus of SDG 4?

Ensuring quality education.

How do SDGs contribute to closing the gap for indigenous Australians?

They provide a framework for measuring progress in addressing indigenous disadvantages globally.

What is anaerobic training?

Training aimed at high intensity and effort duration shorter than aerobic activity, occurring without the presence of oxygen.

What is an example of an anaerobic training program?

Sprint Interval Training (SIT), involving 4-6 repetitions of 30-second sprints at maximum intensity. 2-3 sessions per week

What is the main goal of aerobic training?

To improve cardiovascular endurance and support continuous skills over long durations.

aerobic training program

• alternate between higher and lower intensity periods, or try activities like stair climbing or using an elliptical machine.
