DESCRIPTIONS

1 ELEMENT DESCRIPTIONS

1.1 Test group

A test group is a collection of subjects, for example a football
team. Synchronization with the Powertimer Analyzer removes
all test groups from the

Powertimer SW-300

, but the Powertim-

er Analyzer can be used to upload test groups to

Powertim-

er SW-300

A group contains the following properties:

•

Group Name

identifies the group. There can be multiple

groups with the same name, but that makes selecting the
right group for testing harder.

•

Group Description

is a textual description about the group.

• A group may contain multiple subjects as members.

1.2 Subject

A subject represents one individual that performs tests. A sub-
ject may belong to multiple test groups, for example if the sub-
ject plays ice hockey and football in two different teams. Syn-
chronization removes all subjects from

Powertimer SW-300

but subjects can also be uploaded.

A subject contains the following properties:

•

Subject ID

is a unique identifier, for example social security

number, for the subject. If multiple subjects have the same ID
in synchronization one of them will be removed.

•

Name

identifies the subject in

Powertimer SW-300

. See

chapter 6.2. for more information about subject naming.

•

Birth Date

is required before performing tests.

•

Sex

is needed to calculate results in some tests

•

Sport

identifies the sport the subject practices.

•

Height

is required before performing tests.

•

Weight

is also required before performing tests.

•

Subject

may belong to multiple groups.
