The effect of sustained spinal load on intra-abdominal pressure and EMG characteristics of trunk muscles
Article Abstract:
Twenty-six healthy young adults participated in a study conducted to determine the effect of sustained spinal load on intra-abdominal pressure and EMG characteristics of trunk muscles. The volunteer subjects were required to hold prolonged weight of 9.07 kg, for male subjects, and 6.8 kg, for female subjects, in upright and stooped postures on different days. A torque measuring system with a moment arm and a force measuring unit was used to obtain results. Findings showed that the torque magnitude during upright and prolonged holding tests for both sexes were 249 and 270 s, respectively.

Measures of localized spinal muscle fatigue
Article Abstract:
A study was conducted to determine the best variable, if any, to indicate the level of localized muscle fatigue, in a subject group of six male and six female members. The initial and final values of subjective feelings of fatigue through visual analogue score, rate of perceived exertions and body part discomfort rating were recorded, and it was observed that none of the single variables predicted fatigue reliably for either gender and levels of contraction.
