The purpose of this lab is to measure and analyze the muscle strength and power of an individual through the use 3 techniques: the handgrip test, the indirect 1-RM test, and the Wingate anaerobic power test. Ibelieve that the two strength tests do provide a valid estimation of the subject’s strength, with the indirect 1-RM test being more accurate as it is based on the direct 1-RM. I hypothesize that muscular strength is lower in females than in males due to increased muscle mass in males. I also hypothesize that even though males might have a greater start power, females will have a higher endurance. Furthermore, I hypothesize that an increased body mass (constant height) leads to a decrease in muscular strength and power. I also believe that the Wingate test will not give be a completely proper way to measure anaerobic power since the only muscles involved are the legs—the anaerobic power stored in the upper extremities is not harnessed.

Methods
Hand grip dynamometry procedure:
First, the dynamometer will be adjusted into a proper and comfortable position for the subject. This will include a quick calibration to make sure the needle counter is set to 0. In preparation for the test, the subject will stand erect and then squeeze the dynamometer as hard as possible without any body movement. The process will be run 3 times on each hand (with 30 second rest between each run) and each measurement will be recorded. After 3 trials, each value in kg will be converted into N. The highest score will be used to classify fitnesslevel. The relative force is then calculated by dividing the force (kg) over the body weight (kg). Finally, the % difference between the dominant and non-dominant hands will be calculated.

Indirect 1-RM procedure
First, the dumbbell weight must be calculated by multiplying the body weight by 0.125 (this dumbbell weight is about 1/8 of the body weight). The subject should do as many repetitions are possible from a position starting at 180° and ending in a complete motion (around 20°). Repetitions should be smooth without any generation of momentum. If the subject is about to finish the 20 maximum reps, he/she should stop, rest, and start again with a higher weight. After this, the same test should be run starting again from 180° to only 90°. Finally the 1-RM will be calculated with the achieved repetitions and the known body weight with the following equation
1RM=rep30+1×weight in kg of dumbell
Wingate Anaerobic Power Test procedure:
First, the subject’s body weight must be measured. The cycle ergometer must be adjusted comfortably for the subject performing the test. The resistance applied needs to be calculated by multiplying the subject’s body weight by 0.075. Once the subject is seated on the bike, he/she will start pedaling as fast as possible. As soon as pedaling starts, the resistance should be applied.Simultaneously, the number of revolution made every 5 seconds should be recorded. These observations should be done until the subject can no longer pedal. After the test, the anaerobic power will be calculated for each 5 second interval using the following equation
resistance×6m×revs0.083 min=anaerobic power

Results:
Hand grip dynamometry:
Subject was a 21 year old male, weighing 77 (kg) with a height of 168 (cm).

Table 1: Strength Tests (absolute force)
| Trial 1 (kg) | Trial 2 (kg) | Trial 3(kg) | Best (kg) | Best (N) |
Dominant Hand | 46 | 45 | 48 | 48 | 480 |
Non-Dominant Hand | 37 | 35 | 38 | 38 | 380 |

Table 2: Relative force and absolute ratings
Relative force, dominant hand | .623 (kg) | 6.23 (N) |
Relative force, non-dominant hand | .494 (kg) | 4.94 (N) |
% difference between dominant and non-dominant hands | 23.26% |
Rating for dominant hand | Average |
Rating for non-dominant hand | Very poor |
% of normal value | 83.5% of normal value |

Calculations:
Kilogram conversion to N:

48 kg×10ms2=480 N
38 kg×10ms2=380 N
Relative force:

48 kg77 bw in kg=0.623 kg×10(ms2=6.23 N (dominant hand)
38 kg77 bw in kg=0.494 kg×10(ms2=4.94 N (non-dominant hand)

% difference between dominant and non-dominant hands:

48-3848+382×100=23.26%

% of normal value:

86103×100=83.5%

Indirect1-RM:

This test was performed on one male and one female—results for both will be presented.

Male weighed 80 kg and had a height of 168 cm.
