Static and Dynamic Back Strength of Underground Coal Miners

• Description:
  Twenty-two underground coal miners performed back strength exertions using an isokinetic dynamometer. Static exertions were performed in two postures (standing or kneeling) and three angles of trunk flexion. Dynamic tests were performed in the same postures and at three isokinetic velocities. Results of the static back strength anova indicated that posture and angle of trunk flexion both significantly affected peak torque (p<0.001). Posture and velocity also affected dynamic torque production (p<0.001). Results of this U.S. Bureau of Mines study indicate that back strength is significantly reduced when a kneeling posture is used. [Description provided by NIOSH]
