hypermetropia (ie, images become severely blurred and unfocused) and the eye loses about two-thirds of its refractive power. 13 , 14 Diving masks restore the air-to-cornea interface allowing for high underwater acuity; however, they produce a refraction at their outer surface, which results in a narrowing of

. Participants were allowed to fidget but not walk around during the standing position. Oxygen Consumption A face mask was placed around the mouth and nose to measure gas exchange. Oxygen consumption ( V ˙ O 2 ) and the production of carbon dioxide ( V ˙ CO 2 ) were measured using a respirometer (MetaMax 3B

addition, as an acute-phase protein, serum ferritin may be increased by physical activity, inflammation, and disease, masking actual ID ( Malczewska et al., 2000a ). Nevertheless, ID is still regarded as one of the most widespread nutrient deficiencies affecting almost 50% of the global population

, prior to the 15-minute half-time interval. Blood sampling, BP measurement, and a third battery of CMJ and RT tests were repeated right before and after the third 22.5-minute period. After that, the participants were connected to the gas analyzer by putting on a face mask and embarked on the fourth

elsewhere in this issue ( 2 ), we observed that a significant age effect masks a more specific effect for changes in fatness relative to overall body mass, that is, reflecting lean body mass. If we also include sum of triceps and subscapular skinfold thickness as a covariate in our example of 11- to 16-year

electroencephalographic sensor (Zeo, Newton, MA) that was configured to obtain real-time objective sleep measures. 22 This system has been validated against an in-laboratory polysomnograpy. 23 For the nap, participants were ushered into a darkened room and allowed to nap with the assistance of earplugs and eye masks

above 1.02 and/or a plateau of VO 2 ( Rowland, 1996 ). An electromagnetically braked cycle ergometer (Ergoline, Bitz, Germany) was used to perform the test. VO 2 and VCO 2 were measured breath-by-breath through a mask connected to O 2 and CO 2 analyzers (Oxycon Pro-Delta; Jaeger, Hoechberg, Germany

serial loading avoids the GI disturbances usually reported with such doses ingested acutely ( Burke & Pyne, 2007 ). In addition, capsules were preferred to powder to mask the taste of the substances ingested and allow blinding of the participants to the experimental conditions. Capsules were consumed in

. Although both conditions eliminate visual feedback, in the WB AMEDA testing the participants could follow the natural anatomical posture and look straight forward. Different visual conditions during proprioceptive testing have the potential to mask clinically meaningful differences in proprioceptive acuity
