Skinfold Measurements
Skinfold Measurements
Past literature has looked at the different ways of measuring body composition such as Reilly, Wilson and Durnin (1995) investigated the validity of the skinfold measurements using 5 currently used equations. Brodie (1998) suggests that in order to determine body composition suggests that a quadratic equation should be used n order to get a valid result. This literature also states that there is also strong evidence that measuring the circumference and diameter of lower limbs gives stronger results.
The aims of this experiment where to find out how reliable the four ways of measuring skin fold where for body composition
Results
These results contain two tables and one graph this is to show the results which we obtained when looking at the four different ways of measuring body composition. The table and graph both show mean±SD and the graph is a paired samples t-test comparing the different sites and the bioelectrical impedance.

Mean Std. Deviation
Three site 13.4944 7.44723
Four site 17.1432 7.21744
Seven site 13.7328 6.58844
bio 16.9240 7.31552
Table 1 shows that three skinfold sites and bioelectrical impedance with mean±SD. The results show that the three and four site are pretty similar three site (13.4944) seven site ( 13.7328).

This graph just helps to simplify the data from the table above again it is showing mean±SD.
