warm-up (5 min on a motorized treadmill at 10 kph). The 3-km time trials were performed under controlled laboratory conditions of 18°C, 20.9% O 2 , and 40% humidity. During the time trial, participants wore a heart rate (HR) monitor (Polar RS400; Polar Electro Oy, Kempele, Finland) and a face mask

%–550% increase in salivary [nitrate] and [nitrite]) were ineffective at enhancing performance during 2 consecutive maximal efforts. Finally, as there was no true control condition (with no nitrate), one may argue that the low nitrate dose provided in our study was sufficient to enhance recovery and thereby mask

less demanding field positions, possibly masking their potential best performance levels. Therefore, assessment of performance in a match alone provides a narrowed image, possibly disregarding best possible performance levels. By contrast, testing best performance in an isolated field test or lab

. Practitioners should also be wary of directly comparing athletes’ RSI or RSR values or using RSI or RSR group normative values, as aggregate scores may mask valuable information about individual strategies. Consequently, values should always be presented with the corresponding CTs and JHs or FTs to give greater

patterns in Olympic-style boxing. Second, the possibility remains that a chronically low body weight could mask predominantly gradual weight-loss patterns found among these elite youth boxing athletes. Indeed, the maintenance of chronically low body weight throughout the competitive season was recently

variation on the data. Using the scalable mask automatically provided by the Footscan Software (Footscan 7.1; RSscan International), the footprint was divided into 10 anatomic pressure areas (Figure  2 ): medial heel (HM), lateral heel (HL), metatarsal areas (M1–M5), midfoot (MF), hallux (T1), and toes (T2

-Exchange Parameters Throughout each rowing test, the athletes breathed through a face mask (series 7500; Hans Rudolph, Shawnee, KS) attached to a 2-way nonrebreathing valve (series 2700; Hans Rudolph) with a precalibrated large flow turbine transducer (Morgan Mark 2 ventilation meter, Rainham, Kent, UK) connected to

disease cannot be overstated. We found evidence that combining physical activity across domains masks important variation in the socioeconomic precursors and glucoregulatory sequelae of physical activity. Consistent with the findings of recent systematic reviews, we found that socioeconomic disadvantage

As such, future research could investigate the objective and subjective sleep characteristics and subjective wellness of team-sport athletes who regularly obtain sufficient sleep during intensified

reliability of single urine sampling of T PC may remain skewed. This is rather noteworthy, as the presence of T PC could potentially mask actual fluid-deficit characterization via U SG . Indeed, Fernandez-Elias et al 9 showed that regardless of an overall high-positive correlation between U SG and U OSM
