Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
IPANEMA (Integrated Posture and Activity Network) is a construct consisting of electrodes and several specialized sensors integrated in the textile tissue of a T-Shirt and interconnected with "electronic nods", an equipment supporting the central computerized control system with information via Bluetooth signals.
This body sensor network enables ablations of electrical activity of heart (ECG), Bioimpedance Spectroscopy (BIS), measuring of temperature and humidity on the surface of skin, breathing intensity and acceleration of body movement.
The study is divided in 3 parts, the indoor part, the outdoor part, and the part of measurements under controlled artificial temperature conditions (climate chamber).
The outdoor measurements will be performed at different running tracks, e.g. at the Hochschulsportzentrum, Lousberg, and can be separated in two subtypes, the training and the competition.
The indoor study phase lasts ca. 2 hours, where the volunteers will be analysed during running on a tread mill with both, the IPANEMA system and common medical monitoring procedures. The evaluations of identical physiological parameters obtained by use of stationary diagnostic equipment, the ergospirometric device PowerCube Ergo, BIS measurement system Xitron Hydra 4200, infra-red camera VarioCam®hr-basic and standard medical ECG measurements are used as reference values. Two hours before the start and during the entire training phase, the experimental group is restricted to food and liquid intake in opposite to control group. These experimental conditions purpose to clarify several physiological effects of dehydration during sportive activities. The outdoor- and climate chamber- investigations do not prescribe the liquid deprivation.
The climate chamber measurements will be performed in a temperature controlled room. This measurement session can last up to 3 hours and temperature inside of climate chamber can be increased until 40Cº. Such conditions may simulate body sensor network and elicit physiological effects comparable to effects obtained during sportive activities. No sport is performed by volunteers during the climate chamber phase.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
IPANEMA validation without water intake
The one group is restricted to the water intake during the Indoor phase during testing the IPANEMA measurement system. The other group is not restricted to the water intake.
Validation of the IPANEMA - measurement system
Control of the body conditions under real life conditions during a sportive activity.
