The impact of birth weight (BW) on adult health has been studied, related to the autonomic nervous system, and implicated in cardiovascular risk. We investigated cardiorespiratory and heart rate (HR) autonomic recovery after moderate effort in healthy term-born adults with different BWs. We studied 28 healthy physically active women aged between 18 to 30 years split equally into two groups according to BW: G1 (n = 14), BW between 2500 g and 3200 g and G2 (n = 14), BW > 3200 g. The groups remained seated at rest for 15 min, followed by aerobic exercise on a treadmill (five minutes at 50-55% of maximum HR and 25 min 60-65% of maximum HR) and then remained seated for 60 min during recovery from the exercise. Cardiorespiratory parameters and HR variability (HRV) [RMSSD, HF (ms)] were assessed before and during recovery from exercise. In G1, HR was increased from 0 to 20 min after exercise whilst in G2 HR was higher from 0 to 7 min following exercise. In G1, short-term HRV was increased from 5 to 10 min after exercise but in G2 it recovered prior to 5 min following effort. In conclusion, healthy term-born women with low normal BW present slower HR autonomic recovery after exercise.
体重对成人健康的影响一直是研究的热点，它与自主神经系统有关，并与心血管风险有关。我们研究了不同体重的足月出生的健康成年人在中等强度运动后的心肺和心率（HR）自主恢复情况。我们研究了 28 名年龄在 18 至 30 岁之间的健康、有活力的女性，根据体重分为两组：G1（n=14），体重在 2500 克至 3200 克之间；G2（n=14），体重超过 3200 克。两组人都先在休息时静坐 15 分钟，然后在跑步机上进行有氧运动（5 分钟达到最大心率的 50-55%，25 分钟达到最大心率的 60-65%），然后在运动后的 60 分钟内静坐恢复。在运动前和运动恢复期评估心肺功能参数和心率变异性（HRV）[RMSSD、HF（ms）]。在 G1 中，HR 从运动开始后的 0 分钟增加到 20 分钟，而在 G2 中，HR 从运动开始后的 0 分钟增加到 7 分钟。在 G1 中，短期 HRV 从运动开始后的 5 分钟增加到 10 分钟，但在 G2 中，它在运动后 5 分钟前就恢复了。总之，体重正常偏低的足月出生的健康女性在运动后心率自主恢复较慢。
