Energy expenditure during two weeks of an ultra-endurance run around Australia

Article Abstract:

This study measures the energy expenditure, nutritional intake, and water turnover of a male marathon runner during two-weeks of a long distance run. The intake and expenditure data collected from this case study provides insight into the nutritional needs of other athletes trying to optimize performance and avoid health complications.

Influence of intra-oral maxillary sports mouthguards on the airflow dynamics of oral breathing

Article Abstract:

Results show that maxillary mouthguards increase oral airflow resistance in relation to controlled jaw position but responses differ in individual subjects. Data indicate that this may be due to the involvement of variable compensatory mechanisms such as mouth opening and oral airway dilator muscle activity.
