TEST OF THE WEEK - Running-based Anaerobic Sprint Test (RAST)
Introduction

The Running-based Anaerobic Sprint Test (RAST) was developed at the University of Wolverhampton (United Kingdom) to test an athlete's anaerobic performance. RAST is similar to the Wingate Anaerobic 30 cycle Test (WANT) in that it provides measurements of power and fatigue index.

The Wingate test is more specific for cyclists whereas the RAST provides a test that can be used with athletes where running forms the basis of their sport/event.

Required Resources

To undertake this test you will require:

400 metre track - with a 35 metre marked section on the straight
Two cones to mark the 35 metre section
Stop watch
An assistant
Calculator will be advantageous
How to conduct the test

The athlete

is weighed prior to the test
undertakes a 10 minute warm session
has a 5 minute recovery
completes six 35 metre runs at maximum pace (10 seconds allowed between each sprint for turnaround)
The assistant

records the time taken for each 35 metre sprint to the nearest hundredth of a second
makes appropriate calculations
Calculations

Power output for each sprint is found using the following equations:

Velocity = Distance ÷ Time
Acceleration = Velocity ÷ Time
Force = Weight × Acceleration
Power = Force × Velocity OR Power = Weight × Distance ² ÷ Time ³
From the six times calculate the power for each run and then determine:

Maximum power - the highest value
Minimum power - the lowest value
Average power - sum of all six values ÷ 6
Fatigue Index - (Maximum power - Minimum power) ÷ Total time for the 6 sprints
Example

Athlete’s weight is 76 Kilograms and the times for each 35 sprint are:

4.52 seconds
4.75 seconds
4.92 seconds
5.21 seconds
5.46 seconds
5.62 seconds
The power (Weight x Distance ² ÷ Time ³) for each 35 sprint are as follows:

1008 watts (76 x 352 ÷ 4.523)
869 watts (76 x 352 ÷ 4.753)
782 watts (76 x 352 ÷ 4.923)
658 watts (76 x 352 ÷ 5.213)
572 watts (76 x 352 ÷ 5.463)
525 watts (76 x 352 ÷ 5.623)
Maximum Power = 1008 watts
Minimum Power = 525 watts
Average Power = 736 watts
Fatigue Index = 483 ÷ 30.48 = 15.8 watts/sec

Analysis:

Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.


Maximum Power: Is a measure of the highest power output and provides information about strength and maximal sprint speed. Research range is 1054 watts to 676 watts.

Minimum Power: This is the lowest power output achieved in the six 35 metre sprints and is used to calculate the Fatigue Index.

Average Power: This provides an indication of an athlete's ability to maintain power over time. The higher the score indicates the athlete's ability to maintain anaerobic performance.

Fatigue Index: Indicates the rate at which power declines for the athlete. A low value (<10) indicates the ability for the athlete to maintain anaerobic performance. A high fatigue index value (>10) indicates the athlete may need to focus on improving their lactate tolerance.

How to use

The test is conducted on a regular basis throughout the training program. Results should be compared with the athlete's previous results to determine if the training program is achieving the desired results. Results can then be used to appropriately adjust the athlete's training program.

When to use

RAST can be used on a regular basis (3 to 6 weeks) throughout the season. The period between tests will be determined by the training phase and the amount of training being conducted.

Target Group

This test is suitable for sprint and endurance athletes and players of endurance sports such as football, rugby, and running.

这个测试方法很有趣,我好吸收一下,然后再发表评论.
祝老师和所有同学圣诞节快乐!

campus來信問候大家
我們期待網路連通以後
campus告訴我們RAST的操作評述

有很多有關無氧運動能力的研究以Wingate的測驗方式進行
可是真正以騎車方式進行運動訓練的運動方式比例並不高
RAST應該提供一個很不錯的無氧運動能力測量方法
