Validity of Ergograph as Measurer of Work Capacity 43 

 TABLE VII 



These tables undoubtedly show, by the greater percentages 

 which the fatigue curves after the pause offer, that the pause is 

 more efficient when the reagent does not work to the exhaustion 

 point; the differences except in one case favor the "not to 

 exhaustion" curves. 



The question arises whether this is due to the greater recu- 

 perative value of the pause or to the fact that the nervous centers 

 have not completely exhausted all their energies and the residue 

 remaining back in the centers is carried over and added to the 

 amount which is restored during the pause. In favor of the first 

 hypothesis is the fact that when the contractions are continued 

 to the exhaustion point they produce a condition of temporary 

 or incipient muscle soreness from which recovery during the 

 pause is not complete, in part because recovery is more slow, 

 and hence this condition of the muscles is inhibitory. Introspec-
