While experimental designs provide the best evidence for establishing directionality, most studies in the physical activity setting have used correlational designs, including both cross-sectional ( 6 , 28 ) and longitudinal

Both training regimes were matched for overall load, and these findings indicate an
Improving Utilization of Maximal Oxygen Uptake and Work Economy in Recreational Cross-Country Skiers With High-Intensity Double-Poling Intervals
