1. Place a 1 kg mass in your hand. 2. Lift the mass as many times as possible in 3 minutes. 3. Your hand must always touch the desk at the beginning of each lift. 4. The mass must always touch the shoulder at the end of the lift. 5. Test 1: Record the number of lifts in each minute for 3 minutes without rest. 6. Test 2: Repeat, but take a 30-second rest between each minute. 7. Test 3: Repeat, but take a 1-minute rest between each minute.

How can we measure lung volume?

As you breathe out into the plastic tube, air from your lungs takes the place of water in the bottle. If you breathe out fully, the volume of water pushed out of the bottle is equal to how much air your lungs can hold.

How can we increase lung volume? Regular exercise. A large lung volume: means that more oxygen can enter your body. Smoking diseases such as asthma, and old age can reduce lung volume.

1.State which test showed the greatest level of fatigue. 2.Describe the pattern in the results from minute 1 to minute 3 with no rest between minutes. 3.
