Pain in the heel

The fat pad syndrome is characterized by pain in the center of the heel. The main cause of this syndrome is a rapid increase in the volume of training (time or number of miles run per week) associated with a poor running technique! Some specific tapings associated with low heel shoes are frequently used for this type of problem.

2014-Paulson-Mechanical and Physiological Examination of Barefoot and Shod Conditions in Female Runners

Eight well-trained, female distance runners (mean age=20.11.4 years) completed 3 running economy tests on separate days (barefoot, FiveFingers and usual traditional shoe). Each testing session consisted of a 5-min warm-up at 2.24 m  s-1, followed by the 7-min RE test at 3.13 m  s-1. Statistically significant difference in running economy was found (p=0.04), expressed as relative oxygen uptake per km in the barefoot condition (running shoe: 204.512.84; minimalist footwear: 198.213.04; barefoot: 193.263.62 ml  kg-1 km-1) vs. running shoe. Although not statistically significant (p>0.05), moderate to large effect sizes suggested there were biomechanical changes that ensured between conditions.
Opinion: Again, shoe weight might be responsible for most of this running economy (there are more than 15 studies showing the advantage of less weight on oxygen consumption). Although not significant, a trend with moderate to large effect size for biomechanical changes when barefoot (e.g. increase of 5 steps/minute). However, it's difficult to measure the contribution of these changes in oxygen consumption. According to some other studies, a minimally cushioned but very light shoe (10mm) could have been more economical for some subjects than the barefoot condition. Also, studies like this should recruit more than 8 subjects!

    150 minutes a week of vigorous intensity activity (ex : 5 x 30 min jogging) have extensive health benefits! This document is based on the report submitted by the Physical Activity Guidelines Advisory Committee, a group comprising 13 leading experts in the field of exercise science and public health. The committee conducted an extensive review of the scientific data relating physical activity to health. We know that sedentary behavior contributes to a host of chronic diseases, and regular physical activity is an important component of an overall healthy lifestyle. There is strong evidence that physically active people have better health-related physical fitness and are at lower risk of developing many disabling medical conditions than inactive people.
