effects may be different between males and females. Therefore, the primary aim of this study was to examine whether long-term changes in basal levels of inflammatory cytokines or hepcidin levels were associated with decreased iron levels in highly trained male and female cross-country (XC) runners

Study 1 was focused on different national-level soccer teams of Central and South America (i.e., Mexico, Costa Rica, and Argentina) through a cross-sectional design to

with blood flow restriction (BFR), emerge as effective strategies due to the high muscle activation 3 – 6 and reduced mechanical stress on the joints 7 during their application. It is well-established that LL combined with BFR (LL-BFR) promotes similar increases in muscle cross-sectional area (CSA) 8

The primary purpose of this study was to examine coupled gluteus maximus and medius recruitment patterns during single-limb step-downs using cross-recurrence quantification analyses (cRQAs). Specifically, their contributions to variability in frontal-plane hip
The Multidisciplinary Process Leading to Return From Underperformance and Sustainable Success in the World’s Best Cross-Country Skier
Guro Strøm Solli, Espen Tønnessen, and Øyvind Sandbakk
Cross-country (XC) skiing is a challenging endurance sport, where maximal oxygen uptake (VO 2 max) and VO 2 at the lactate threshold are critical for performance. 1 – 3 In addition, the technical demands in XC skiing are high, requiring many hours of deliberate training in the various

Studies were considered for inclusion if they met the following criteria: (1) observational studies that were either prospective or cross
The Effect of Maximal Speed Ability, Pacing Strategy, and Technique on the Finish Sprint of a Sprint Cross-Country Skiing Competition

Sprint cross-country (XC) skiing involves a 1.0- to 1.8-km qualifying time-trial race followed by 3 subsequent knockout heats where 6 competitors in each heat compete for the first ranks that qualify for the next round and/or for winning the final. Although maximal oxygen uptake (VO 2 max
Gait Dynamics on a Cross-Slope Walking Surface
Philippe C. Dixon and David J. Pearsall
The purpose of this study was to determine the effect of cross-slope on gait dynamics. Ten young adult males walked barefoot along an inclinable walkway. Ground reaction forces (GRFs), lower-limb joint kinematics, global pelvis orientation, functional leg-length, and joint reaction moments (JRMs) were measured. Statistical analyses revealed differences across limbs (up-slope [US] and down-slope [DS]) and inclinations (level; 0°; and cross-sloped, 6°). Adaptations included increases of nearly 300% in mediolateral GRFs (p < .001), functional shortening the US-limb and elongation of the DS-limb (p < .001), reduced step width (p = .024), asymmetrical changes in sagittal kinematics and JRM, and numerous pronounced coronal plane differences including increased US-hip adduction (and adductor moment) and decreased DS-hip adduction (and adductor moment). Data suggests that modest cross-slopes can induce substantial asymmetrical changes in gait dynamics and may represent a physical obstacle to populations with restricted mobility.
