1.3 Test
There are currently 19 tests in Powertimer. Detailed description
of the properties, parameters and results of each test can be
found from chapter 8.
1.4 Test action
A test action is a collection of results measured by the Power-
timer
Measurement Unit
. For example, a subject might perform
five jumps within a test action. Usually the best result from a
test action is used to generate reports. Synchronization re-
moves all test actions from
Powertimer SW-300
.
A test action has the following properties:
•
Action ID
is a number that identifies the action, for exam-
ple ID = 5
•
Test Session
the action belongs to.
•
Subject
that performed the action.
•
Group
the subject belonged to when she performed the ac-
tion.
•
Test
that was performed.
•
Height
and
weight
of the subject when she performed the
action. Since these may change as time goes by, the calcu-
lations of old results will be affected if the subject’s data is
used directly.
1.5 Test result
A test action consists of one or more test results. Each result
is a time value that has been obtained from the Powertim-
er
Measurement Unit
. The measurement results are the used
to calculate other results, for example the jump height can
be calculated from the jump time that was measured and the
jump power can be calculated from the jump time and the
weight of the subject. Synchronization removes all results from
Powertimer SW-300
.
A result contains the following properties:
•
Result ID
is a number that identifies the result, for example
ID = 27
•
Test Action
this result belongs to.
•
Type
of result, for example
Contact Time
.
•
Value
of the result, usually in milliseconds. The value is then
used in various calculations so that proper results can be
shown on the screen of
Powertimer SW-300
.
1.6 Test parameters
There are three categories of test parameters in
Powertim-
er SW-300
:
Global Parameters, Test-Specific Parameters
and
Result-Specific Parameters
. These are described in chapter 3
where the testing procedure is explained. Each test has pa-
rameters that belong to these categories and explanations
for these can be found from chapter 8 where the tests are de-
scribed. Synchronization removes all test- and result-specific
parameters from
Powertimer SW-300
.
Parameters have two properties:
Type
and
Value
. For exam-
ple: Distance = 10 meters
1.7 Test session
A session is a group of test actions made by a test group. The
actions of one session should be made within one day, since
session has a date. However, nothing prevents the usage of
the same session on the next day if the session is not synchro-
nized into the Powertimer Analyzer. Synchronization removes
all sessions from
Powertimer SW-300
.
A session has the following properties:
•
Name
of the session. This identifies the session and should
be unique. It is possible to have multiple sessions with the
same name, but it might make test result browsing harder.
•
Date
when the tests were performed. This is automatically
assigned when the session is created.
