TABLE IV. LuxG Capacity. 



It is seen that increase of lung capacity has taken place at 

 all the percentile grades. After seven months' gymnastic 

 training the value of the 30 per cent grade (2.65) is equal to 

 the value at the 50 per cent grade before the training, and 

 the value at the 50 per cent grade after the training (2.87)

 the training the value at the 10 per cent grade (94.5) is 

 higher than the value of the 50 per cent grade before the
