Abstract

UNLABELLED

The objective of the study was to assess changes in body composition, blood lipid and lipoprotein concentrations in 18-24-year-old women during the period of two-month aerobic cycling training.

MATERIAL AND METHODS

Young, healthy, nonsmoking women (n=19) volunteered to participate in this study. They were divided in two groups: experimental (E, n=10) and control (C, n=9). The subjects of group E exercised 3 times a week with intensity of the first ventilatory threshold and duration of 60 min. The group C did not exercise regularly over a two-month period of the experiment. The subjects of group E were tested before and after 2, 4, 6 and 8 weeks of the experiment. The participants of group C were tested twice with an eight-week interval.

RESULTS

Body weight, body mass index, body fat mass, and triacylglycerol (TAG) concentration decreased and high-density lipoprotein cholesterol (HDL-ch) concentration increased after the 8-week training program in the experimental group (P<0.05). Blood total cholesterol (Tch) and low-density lipoprotein cholesterol (LDL-ch) concentrations did not change significantly. Body weight and body mass index started to decrease after 2 weeks of the experiment, but significant changes were observed only after 6 and 8 weeks. Body fat mass was significantly decreased after 2 and 8 weeks of aerobic training. A significant increase in HDL-ch concentration was observed after 4, 6, and 8 weeks. A significant decrease in TAG concentration was observed after 2-week training. No significant changes in all the parameters except TAG (it was slightly increased) were seen in the control group.

CONCLUSIONS

The two-month aerobic cycling training (within VT1, 60-min duration, three times a week) may induce significant changes in the parameters of body composition--body weight, body mass index, body fat mass, and blood lipids--in young women. The following significant changes were observed: TAG level decreased after 2 weeks, body mass and body mass index decreased after 6 weeks, body fat mass decreased and HDL-ch level increased after 8 weeks. Peak oxygen uptake increased after 4 weeks.

摘要

未加标签

本研究的目的是评估 18-24 岁女性在为期两个月的有氧单车训练期间身体成分、血脂和脂蛋白浓度的变化。

材料和方法

年轻、健康、不吸烟的女性（n=19）自愿参加这项研究。她们被分为两组：实验组（E，n=10）和对照组（C，n=9）。组 E 的受试者每周运动 3 次，强度为第一通气阈，持续 60 分钟。C 组在实验的两个月期间没有定期运动。组 E 的受试者在实验前和实验后 2、4、6 和 8 周进行测试。C 组的参与者在 8 周的间隔内进行了两次测试。

结果

经过 8 周的训练计划，实验组体重、体重指数、体脂量和三酰甘油（TAG）浓度降低，高密度脂蛋白胆固醇（HDL-ch）浓度升高（P<0.05）。总胆固醇（Tch）和低密度脂蛋白胆固醇（LDL-ch）浓度无显著变化。体重和体重指数在实验开始后 2 周开始下降，但仅在 6 周和 8 周后观察到显著变化。体脂量在有氧训练 2 周和 8 周后显著降低。HDL-ch 浓度在 4、6 和 8 周后显著升高。TAG 浓度在 2 周训练后显著降低。对照组除 TAG（略有增加）外，所有参数均无显著变化。

结论

为期两个月的有氧单车训练（在 VT1 内，持续 60 分钟，每周 3 次）可能会引起年轻女性身体成分参数的显著变化——体重、体重指数、体脂量和血液脂质。观察到以下显著变化：TAG 水平在 2 周后下降，体重和体重指数在 6 周后下降，体脂量在 8 周后下降，HDL-ch 水平在 8 周后升高。峰值摄氧量在 4 周后增加。
