The purpose of this study was to quantify the visual information of physical therapy students observing demonstrations from different positions by using an eye movement measurement device, and to examine their understanding and learning of tasks from different positions.
The purposes of this study were to compare the respiratory function of non-obese and obese young healthy subjects, and to clarify the relationship between the respiratory function and the body composition (e.g. the amount of skeletal muscle in the limbs). [Participants and Methods] The subjects were defined as non-obese if their Body Mass Index (BMI) was less than or equal to 24 and their waist was less than 84 cm, and as obese if their BMI was greater than or equal to 25 and their waist was greater than or equal to 85 cm. [Results] The obese group had significantly higher %VC and %FEV1.0 than the non-obese group. In the non-obese group, there was a negative correlation between %PImax and BMI. In the obese group, there was a significant positive correlation between %ERV and right upper extremity muscle mass and BMI. [Conclusion] The results suggest that obesity may reduce respiratory function in young people.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
