2013 PHYSICAL EDUCATION SCHOOL-ASSESSED COURSEWORK
Task: A visual presentation which focuses on the acute effects that physical activity has on the cardiovascular, respiratory and muscular systems of the body.
Performance descriptors
The following descriptors provide a guide to the levels of performance typically demonstrated within each range on the assessment task/s.
MARK RANGE
DESCRIPTOR: typical performance in each range
17–20 marks
Comprehensive and detailed analysis of collected data, thorough and insightful understanding of the mechanisms responsible for acute effects of the cardiovascular, respiratory and muscular systems of the body.
Key knowledge
This knowledge includes:
• the mechanisms responsible for the acute responses to exercise in the cardiovascular, respiratory and muscular systems
• characteristics and interplay of the three energy systems (ATP – CP, anaerobic glycolysis, aerobic system) for physical activity, including rate of ATP production, the capacity of each energy system and the contribution of each energy system
• fuels (both chemical and food) required for resynthesis of ATP during physical activity and the utilisation of food for energy
• relative contribution of the energy systems and fuels used to produce ATP in relation to the exercise intensity, duration and type
• oxygen uptake at rest, during exercise and recovery, including oxygen deficit, steady state, and excess post-exercise oxygen consumption
Key skills
These skills include the ability to:
• describe, using correct terminology, the interplay and relative contribution of the energy systems in different sporting activities
• participate in physical activities to collect and analyse data relating to the range of acute effects that physical activity has on the cardiovascular, respiratory and muscular systems of the body • perform, observe, analyse and report on laboratory exercises designed to explore the relationship between the energy systems during physical activity
• explain the role the energy systems play in enabling activities to occur
Measuring Heart Rate and Respiratory Rate during continuous and intermittent physical activity
Outline
For this School Assessed Coursework students will undertake two tasks;
- A laboratory for collection of data, and
- A visual presentation
Task 1 (4 marks)
Students are to collect heart rate (heart rate monitors) and breathing rate (direct observation) data from two groups of subjects within their class who will undertake varied physical activity for 10 minutes.
Instructions for Group 1:
The first group will complete 10-minutes of continuous cycling on a spin bike. The intensity should be around 5-7 on a ‘Borg’s
