ULTIMATE FRISBEE PRAC
Aim: To conduct an activity analysis on one individual participating in physical activity to determine the relative contribution of the energy systems to the activity.
Activity: Ultimate Frisbee
Data Collection: Collecting accurate and relevant data is a vital component of the practical session. We will focus on collecting and analysing data from two participants. Data collected will include: movement patterns, skill frequencies, heart rates and work to rest ratios.
Table 1: Movement Patterns
Using a tally system record how many times each movement is performed at the relevant distances. Then add the totals together (total number of each movement, total number of each distance and total distance of each movement). Calculate the percentage of each type of movement and the average distance of each movement.
Movement / Intensity / 0-5m / 5-10m / 10-15m / 15+m / Total / Distance / % Total (Distance/Total) / Average(m)
Walk / Low
Jog / Med/Low
¾ Pace / High
Sprint / V. High
Totals / 100%
Table 2: Skill Frequency
Using a tally system record how many times each skill is performed and then add up the total for each skill.
Skill / Frequency / TotalShort Pass (<5m)
Long Pass (>5m)
Catch
Gather off ground
Jump
Defend
Intercept
Table 3 – Heart Rates
At the appropriate times ask the participant for their heart rate. Record these heart rates. Then calculate their average heart rate for the recording period and record their maximum heart rate.

Table 4: Playing Intensity v. Duration
Closely watch the selected the participant and using a stopwatch record the duration (seconds) of each period of work. Then categorise this period of work into high (H), medium (M) and low (L). After the participant has performed a work period take note of how long the period of rest goes for (seconds) and record below.
High: sprinting, ¾ pace, change of direction, jumping
Medium: jogging
Low: walking, standing

Discussion Questions:
1. Using the data in Table 1: what were the most common movement patterns? What energy system(s) would these predominantly rely on, based on intensity of performance?
2. Discuss how the lactic acid system provides energy for movement. In your discussion provide information on: food fuel, by-products, duration and a netball example.
3. Using the data from Table 2: what were the most common skills performed by the participants? Explain which energy system would have been dominant in the rebound skill. In your explanation provide information on: food fuel, storage site of fuel, recovery time, intensity and duration.
4. What is the chemical compound that provides the energy that allows muscular movement? Explain how this chemical provides energy for our bodies. A diagram may assist your explanation.
5. Describe in detail the interplay of the three energy systems in ultimate frisbee. In particular, focus on a player in the centre (C) position and provide specific examples of the different use of the three energy systems.
6. Discuss the interplay of the three energy systems for the centre (above) compared to a player in a defensive position.
7. Using the data in Table 3: what was the average heart rate? To complete a full game of ultimate frisbee (4 x 15min) which energy system would be vital? Describe in detail the three stages of energy production for this system. Include diagrams to assist your explanation.
