Key result
Synchronized swimmers with a lower fatigue index and higher non-lactic anaerobic power demonstrated significantly faster heart rate recovery and lower blood lactate levels after a 4-minute competitive routine (p<0.05).
Why the study?
Does baseline anaerobic power and fatigue index affect heart rate recovery and blood lactate removal after intense exercise in synchronized swimmers?

p-value: p=<0.05
Muscular adaptations, reflected by anaerobic power and fatigue index, may play a more critical role in cardiometabolic recovery and lactate removal than aerobic capacity alone.
Anaerobic power and fatigue resistance were associated with faster recovery in synchronized swimmers; hypothesis-generating for prospective training studies.
The aim of this study was to measure the differences in cardiorespiratory recovery (CR) and blood lactate removal among young athletes with differences in non-lactic (NP) and lactic anaerobic power (LP) and fatigue index (FI) but with the same degree of cardiorespiratory fitness. Sixteen swimmers from the Brazilian synchronized swimming team (2014) were divided into two groups GAP (Group High Power) (n = 9), with NP, LP, and FI (p<0.05) compared to GBP (Group Low Power) (n=7). Both groups performed a four-minute routine at competitive intensity. Anaerobic power, maximal heart rate (HR) and blood lactate (BL) were determined before and at 1, 3 and 5 minutes after the routine. Student’s t-test was used to analyze the intergroup differences of NP, LP, FI, maximum and lactic HR, and two-way ANOVA followed by Bonferroni was used to analyze HR and BL at 1, 3 and 5 minutes after activity with a significance of 5%. The FI of the GBP group was lower than that of the GAP group (P <0.05). The NP of the GBP group was higher than that of the GAP group (P <0.05). The maximum HR of the GBP group was equal to that of the GAP group (P> 0.05). The GBP group had better HR recovery than did the GAP group (P <0.05). BL had its lowest levels after 1 and 5 minutes of recovery in the GBP group when compared to the GAP group (P <0.05). The GBP group’s FI was significantly lower than that of the GAP group, while NP was higher, and CR was better in the GBP group, indicating a relationship between a lower FI and higher NP and LP with CR and suggesting that muscular adaptations have an important influence on CR and BL removal.

Meza et al. (2018) conducted a cross-sectional in Healthy athletes (n=16). Lower fatigue index and higher non-lactic anaerobic power profile vs. Higher fatigue index and lower non-lactic anaerobic power profile was evaluated on Heart rate recovery and blood lactate removal at 1, 3, and 5 minutes post-exercise (p=<0.05). Synchronized swimmers with a lower fatigue index and higher non-lactic anaerobic power demonstrated significantly faster heart rate recovery and lower blood lactate levels after a 4-minute competitive routine (p<0.05).
