We aimed to describe the changes in footprint characteristics after 2 types of resistance training sessions performed at different intensities. 18 young subjects (8 men and 10 women) volunteered for the study. All of them performed 2 different resistance training sessions, one with light loads (LS) and the other with heavy loads (HS). Their footprint was recorded and analysed before and after exercise. Lengths, widths, and areas of the footprint (rearfoot, midfoot, and forefoot) were measured. Almost all the variables significantly increased after both sessions. The greatest changes were found in the midfoot (area, LS: 10.4%; HS: 8.1%, P<0.0005; width, LS: 7.5%, P=0.002, and HS: 8%, P<0.0005). However, there were no significant differences between post-exercise data from both sessions. The variable that showed the smallest changes was the foot length (LS: 0.3%, P=0.023; HS: -0.4%, P=0.549). A resistance training session led to increases in most of the dimensions of the footprint, regardless of the magnitude of the loads handled. The greatest changes were found in the midfoot, indicating that the foot was flatter after exercise, and the foot changed more in width than in length.

Men de gäller bara före och efter ett pass, går foten tillbaka sen då eller är de permanent? För läser man låser de som de är temporärt.

Är det bara jag eller borde detta ha med att de flesta pronerar en aning och att vid belastning tenderar då folk att pronera mer vilket i sin tur ger större trampyta(på bredden)?
