Table 3 Effect of the endurance protocol on shoulder strength using a high-standardized method during session one (n = 21).

From: Shoulder muscle endurance: the development of a standardized and reliable protocol

    Mean SD Percentage of change
Isometric maximal strength (kg) Flexion Baseline 20.2 8.1  
   After protocol 15.8* 6.2 - 22%
  External Rotation Baseline 20.4 5.2  
   After protocol 16.9* 4.4 - 17%
Isokinetic mean peak torque (Nm) External Rotation Baseline 21.4 7.6  
   After protocol 21.3 7.8 0%
  Internal Rotation Baseline 31.9 12.1  
   After protocol 31.4 12.0 -2%
Total work during endurance protocol (J) External Rotation First Third 395.7 189.1  
   Last Third 245.2* 86.4 - 38%
  Internal Rotation First Third 592.8 299.6  
   Last Third 339.8 153.4 - 43%
  1. * Significant differences compared to the baseline strength measurements.
  2. Significant differences compared to the total work in the first third of the endurance protocol.
