72.0 ± 7.5 kg, training experience 8.9±3.3 years) volunteered
to participate.
The maximal muscle torques of ten muscle groups:
flexors and extensors of an elbow, shoulder, hip, knee
and trunk were measured under static conditions with
the use of new special devices (“JBA”, Zbigniew
Staniak, Poland) – type LR1-P (upper extremities) and
TBK2-PM (lower extremities and trunk). Technical
characteristics of the measuring device are as follows:
• torque meter: strain gauge head – measuring
range for 0 to 500 N·m for LR1-P and 0–2000 N·m for
TBK2-PM,
• relative error in strain-gauge bridge amounts to
1.0%.
