The lessened number of heartbeats to do more work in a stand-
ardized pattern indicates that it costs less to do more when training
and conditioning have increased Production. When the five pulse
rates add up to less than 450 it is a sign of good conditioning. ‘The
factor of less heart beats is generally a sign of better condition. The
time of complete recovery of the original pulse rate is more indica-
tive of good condition. As will be noted in Figure 4, there is com-
paratively more recovery in the first two minutes of rest than there
will be in the next half hour. This indicates the need of frequent
short rest periods with spurt periods of work leading to greater
development and improved function. :

The average Production of each day paralleled with the average
pulse index of that day can be plotted into a curve of improvement.
The Production or the number of foot contacts go up. The costs
in heartbeats go down. At the end of the fifth day Production is
up 8.27% and the Costs are down 12.34%.

2. Senior High School Series of Fatigue Curves 1943—
Training and Conditioning

Twenty athletes of the Wilmerding, Pennsylvania, High School,
under Walter West each produced a fatigue curve daily for ten
days to aggregate 200 fatigue curves. The average figures, inning
by inning, for the entire period offer further support to prove the
fatigue curve an instrument of measuring effort to demonstrate
declining returns. The average Production of 200 different curves
1/20 to 2/2/43 by innings is given below and results in a perfect
fatigue curve. .
