Key result
Sub-maximal cardiovascular load decreased pre-shooting frontal-midline theta power and increased temporal and occipital alpha power, while shooting accuracy did not change.
Why the study?
Does sub-maximal cardiovascular load influence EEG activity preceding biathlon shooting in experienced biathletes?
Population
13 experienced biathletes (mean age: 17 years; 5 males, 8 females)
Comparison
Shooting immediately after 3-minute exercise on… vs Shooting at rest (fixed-order conditions)
Design
Fixed-order conditions (not randomized)

Accuracy preserved under load suggests no practice change; leaves open EEG as performance biomarker pending larger validation.
Does sub-maximal cardiovascular load influence EEG activity preceding biathlon shooting in experienced biathletes?
Sub-maximal cardiovascular load alters pre-shooting EEG activity (decreased frontal-midline theta and increased temporal/occipital alpha power), but trained biathletes maintain shooting accuracy through compensatory neural efficiency.
Gallicchio et al. (2016) studied Healthy experienced biathletes (n=13). Sub-maximal cardiovascular load vs. At rest was evaluated on Shooting accuracy and EEG activity (frontal-midline theta and alpha power). Sub-maximal cardiovascular load decreased pre-shooting frontal-midline theta power and increased temporal and occipital alpha power, while shooting accuracy did not change.
