(1) Rising on the toes as many times as possible.
(2) Deep knee bending, or squatting as far as possible and rising to the standing posture, repeating as often as possible.
(3) While lying on the back, raising the legs from the floor to a vertical position and lowering them again, repeating to the point of physical exhaustion.
(4) Raising a 5-lb. dumb-bell (with the triceps) in each hand from the shoulder up to the highest point above the head, repeating to the point of physical exhaustion.
(5) Holding the arms from the sides horizontally for as long a time as possible.
(6) Raising a dumb-bell (with the biceps) in one hand from a position in which the arm hangs down, up to the shoulder and lowering it again, repeating the motion to the point of physical exhaustion. This test was taken with four successive dumb-bells of decreasing weight, viz., 50, 25, 10 and 5 lbs. respectively.
(7) Running on the gymnasium track at a speed to suit the subject, to as great a distance as possible.
The mental test consisted of adding specified columns of figures as rapidly as possible, the object being to find out whether the rapidity of performing such work tended to improve during the experiment.
| Average. | ||||||||
|---|---|---|---|---|---|---|---|---|
| B | Lq. | Lw. | M | P | R | T | W | |
| Jan.–Mar. | 33+ | 36 | 50 | — | 26 | 18+ | 66+ | 33 |
| Jan.–June | 84+ | 84+ | 181 | 29 | 56+ | 89+ | 80+ | 107+ |
The figures of this table show an undoubted increase in endurance, both for the first half and more especially for the whole period of the experiment.
