Effect of Exercise Intensity on Biathlon Standing Shooting Performance and Rifle Movement during Outdoor Roller Skiing
Full text linkPurpose The objective of this study is to investigate the effect of exercise intensity on standing shooting performance and related technical variables in elite biathletes performing roller skiing and live shooting outdoors. Methods Nineteen male biathletes performed two 5-shot series in the following order of exercise intensity: rest, low (percentage of maximum heart rate, 73 ± 4; blood lactate, 1.5 ± 0.3 mmol·L−1), moderate (84 ± 3; 2.4 ± 0.6), “race-pace” (90 ± 2; 4.5 ± 0.8), and “final-lap” (i.e., near-maximal effort: 93 ± 3; 8.7 ± 1.4). Except for rest, each shooting series was preceded by 1-km roller ski skating on a competition track. Rifle movements and triggering were determined from marker-based motion capture and accelerometer data. The primary variables were shooting outcome (hit/miss) and distance from center (dC), determined from an electronic target, and barrel velocity. Mediation analyses for shooting outcome and dC were conducted with barrel velocity (mean over last 0.25 s before triggering) as mediator and intensity as predictor. Results Exercise intensity increased the likelihood of miss at “race” (odds ratio (OR), 2.2; 95% CI, 1.0–4.7) and “final-lap” (OR, 2.8; 95% CI, 1.4–5.8) intensities compared with rest, with no meaningful differences between rest, low, and moderate intensities. Furthermore, intensity affected dC (~32 ± 15 mm at rest, low, and moderate, 36 ± 20 mm at “race,” and 40 ± 23 mm at “final-lap”; P < 0.001). Barrel velocity was a partial mediator of both shooting outcome and dC, explaining some, but not all, of the effect of intensity. Conclusions Exercise intensity seems to have a clear negative effect on standing shooting performance in biathlon, which is partially explained by an increase in barrel velocity. Deteriorating effects were mainly seen at the two highest (race-like) intensities. Accordingly, for specificity reasons, more shooting practice should perhaps be performed at higher, competition-like exercise intensities than what is currently the norm.acceptedVersio

A Latitudinal Cline in the Taxonomic Structure of Eelgrass Epifaunal Communities is Associated With Plant Genetic Diversity
Full text linkAim: Biogenic structural complexity increases mobile animal richness and abundance at local, regional and global scales, yet an-imal taxa vary in their response to complexity. When these taxa also vary functionally, habitat structures favouring certain taxamay have consequences for ecosystem function. We characterised global patterns of epifaunal invertebrates in eelgrass (Zosteramarina) beds that varied in structural and genetic composition.Location: North America, Europe and Asia.Time Period: 2014.Major Taxa Studied: Peracarid crustaceans and gastropod molluscs.Methods: We sampled epifaunal invertebrate communities in 49 eelgrass beds across 37° latitude in two ocean basins con-currently with measurements of eelgrass genetic diversity, structural complexity and other abiotic and biotic environmentalvariables. We examined how species richness, abundance and community composition varied with latitude and environmentalpredictors using a random forest approach. We also examined how functional trait composition varied along with communitystructure.Results: Total species richness decreased with latitude, but this was accompanied by a taxonomic shift in dominance from pera-carid crustaceans to gastropods, which exhibited different sets of functional traits. Greater eelgrass genetic diversity was stronglycorrelated with both richness and abundance of peracarids, but less so for gastropods.Main Conclusions: Our results add to a growing body of literature that suggests genetic variation in plant traits influences theirassociated faunal assemblages via habitat structure. Because peracarids and gastropods exhibited distinct functional traits, ourresults suggest a tentative indirect link between broad-scale variation in plant genetic diversity and ecosystem function.publishedVersio
