This study examined the effects of 6-week Nordic walking (NW) workout with individually customized intensity, on the body composition, and oxidative stress biomarkers for women > 55 years of age.
Sixteen sedentary women (age 58.1±2.02 years old, body mass index (BMI) 26.74±2.72 kg/m2) worked out the NW 3 times/week over the 6-week period. Training intensity, which reflected the dominance of oxygen metabolism, was determined based on changes in physiological indicators during graded exercise on a treadmill (walking with poles). The body composition and oxidative stress biomarkers in blood were measured before and after the exercise routine.
After the training period, body weight, body fat percentage, body mass index and uric acid levels in serum decreased significantly (p < 0.05). At the same time the plasma total antioxidant status increased considerably (p < 0.05), while the total oxidative status and the oxidized low-density lipoproteins concentration levels did not change significantly (p > 0.05).
Within a relatively short time, the Nordic walking with the customized intensity level focused on the dominance of fat metabolism, decreased body fat and improved the blood antioxidant defense system for previously sedentary women. Int J Occup Med Environ Health 2017;30(3):445-454.
本研究探讨了为期6周的个性化定制强度的北欧式健走（NW）锻炼对55岁以上女性身体成分和氧化应激生物标志物的影响。
16名久坐不动的女性（年龄58.1±2.02岁，体重指数（BMI）26.74±2.72kg/m²）在6周内每周进行3次NW锻炼。训练强度反映了氧代谢的主导地位，根据在跑步机（使用手杖行走）上进行分级运动时生理指标的变化来确定。在锻炼前后测量血液中的身体成分和氧化应激生物标志物。
训练期结束后，血清中的体重、体脂百分比、体重指数和尿酸水平显著下降（p<0.05）。同时，血浆总抗氧化状态显著增加（p<0.05），而总氧化状态和氧化型低密度脂蛋白浓度水平无显著变化（p>0.05）。
在相对较短的时间内，针对脂肪代谢主导地位进行定制强度水平的北欧式健走，可降低久坐女性的体脂并改善其血液抗氧化防御系统。《国际职业医学与环境卫生杂志》2017年；30(3):445 - 454。
