Table 2 Effect of the endurance protocol on shoulder strength using a low-standardized method during session one (n = 15).

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

    Mean SD Percentage of change
Isometric maximal strength (kg) Flexion Baseline 22.7 5.0  
   After protocol 19.2* 3.8 - 15%
  External Rotation Baseline 20.6 5.0  
   After protocol 18.8* 4.3 - 9%
Isokinetic mean peak torque (Nm) External Rotation Baseline 20.2 9.9  
   After protocol 21.5 10.4 + 6%
  Internal Rotation Baseline 23.7 10.3  
   After protocol 26.2 10.7 + 11%
Total work during endurance protocol (J) External Rotation First Third 297.5 174.7  
   Last Third 215.2* 126.7 - 28%
  Internal Rotation First Third 362.8 218.0  
   Last Third 267.6 126.6 - 26%
  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.
