Abstract：
:To determine if in-season changes in heart rate recovery (HRR) are related to aerobic fitness and performance in collegiate rowers. Twenty-two female collegiate rowers completed testing before and after their competitive season. Body fat percentage (BF%) was determined by dual-energy X-ray absorptiometry. Maximal aerobic capacity (VO2max ) and time to exhaustion (Tmax ) were determined during maximal rowing ergometer testing followed by 1 minute of recovery. HRR was expressed absolutely and as a percentage of maximal HR (HRR%1 min ). Variables were compared using paired Wilcoxon tests. Multivariable regression models were used to predict in-season changes in HRR using changes in VO2max and Tmax , while accounting for changes in BF%. From preseason to post-season, VO2max and BF% decreased (3.98±0.42 vs 3.78±0.35 L/min, P=.002 and 23.8±3.4 vs 21.3±3.9%, P<.001, respectively), while Tmax increased (11.7±1.3 vs 12.6±1.3 min, P=.002), and HRR%1 min increased (11.1±2.7 vs 13.8±3.8, P=.001). In-season changes in VO2max were not associated with HRR%1 min (P>.05). In-season changes in Tmax were related to changes in HRR%1 min (β=-1.67, P=.006). In-season changes in BF% were not related to changes in HRR (P>.05 for all). HRR1 min and HRR%1 min were faster preseason to post-season, although the changes were unrelated to VO2max . Faster HRR%1 min post-season was inversely related to changes in Tmax . This suggests that HRR should not be used as a measure of aerobic capacity in collegiate rowers, but is a promising measure of training status in this population.
