The Tokyo Olympics and Paralympic games in 2020 will be held in hot and humid conditions. Heat acclimation (in a climatic chamber) or heat acclimatization (natural environment) is essential to prepare the (endurance) athletes and reduce the performance loss associated with work in the heat. Based on the 1990-2018 hourly meteorological data of...

Endurance performance deteriorates in a warm climate. The main cause is an increase in objective body temperature and temperature sensations. Therefore a special headgear was developed for an Olympic rower. The goal of the new headgear was to enhance performance by diminishing the increase in head temperature due to solar radiation in the warm...

Subchondral bone provides structural support to the overlying articular cartilage, and plays an important role in osteochondral diseases. There is growing insight that the mechanical features of bone are related to the biochemistry of the collagen network and the mineral content. In the present study, part of the normal developmental process and...

Pre-cooling is used with increasing frequency in athletics, because high core temperatures lead to deterioration in performance. This study compared the effects of two pre-cooling methods on the increase of core temperature during exercise in a warm environment. Pre-cooling was accomplished using a cold water perfused suit or by performing light...
