摘要
该研究调查了在相对较短的距离内,与汽车通勤相比,骑自行车是否对生理变量、心脏代谢健康和大气中的二氧化碳排放量有积极影响。骑自行车通勤者(11 M, 15 F);年龄[中位数(四分位数间距)]51.5(38.3-56.8)岁;体重指数[BMI] 22.8 (21.0-24.1) kg -2)与汽车通勤者(12 M, 19 F)比较,年龄47.0(36.0-56.5)岁;体重指数23.5 (21.4-24.9)kg -2)。在这项研究的纵向研究中,20名汽车通勤者在24周后改用自行车通勤(汽车→自行车通勤者),他们被重新评估。测量包括峰值有氧能力(V²峰值${\dot V_{{\mathrm{O}}_2}{\mathrm{O}}_2}{\mathrm{峰值}}}}$)和循环力计上的呼吸阈值,被动腿部运动(PLM)测试期间股总动脉血流量增加,能量消耗和上下班时呼出的V²O ${\ mathrm{C}}{{\mathrm{O}}_2}}}$。骑自行车上下班的人有较高的V²O峰值${\dot V_{{\ mathm {O}}_2}{\ mathm{}}}}$(33.7(31.3-38.1))比25.3 (23.5-28.9)mL kg-1 min-1, P V²O峰值${\dot V_{{\ mathm {O}}_2}{\ mathm{}}}}$和PLM变量增加。自行车通勤时的代谢二氧化碳排放量比汽油车少12倍。在中等运动量的个体中,与汽车通勤相比,中等强度的短途自行车通勤对一些生理功能和环境因素有积极影响。
Commuting by bicycle (vs. by car) is associated with improved aerobic power, microvascular function and diminished CO2 output in the atmosphere.
The study investigated whether bicycle compared with car commuting, over relatively small distances, has positive effects on physiological variables, cardiometabolic fitness and CO2 output in the atmosphere. Bike Commuters (11 M, 15 F; age [median value (interquartile range)] 51.5 (38.3-56.8) years; body mass index [BMI] 22.8 (21.0-24.1) kg m-2) were compared with Car Commuters (12 M, 19 F; age 47.0 (36.0-56.5) years; BMI 23.5 (21.4-24.9) kg m-2). In a longitudinal arm of the study, 20 Car Commuters were re-evaluated after they switched for 24 weeks to bicycle commuting (Car→Bike Commuters). Measurements included peak aerobic power ( ) and ventilatory thresholds on a cycle ergometer, blood flow increase in the common femoral artery during a passive leg movement (PLM) test, energy expenditure and exhaled during commuting. Bike Commuters had higher (33.7 (31.3-38.1) versus 25.3 (23.5-28.9) mL kg-1 min-1, P < 0.001) and ventilatory thresholds than Car Commuters, higher Δpeak blood flow (+25%, P = 0.04) and area under the blood flow versus time curve (+46%, P = 0.03) during PLM, and an enhanced skeletal muscle oxidative metabolism. and PLM variables increased in Car→Bike Commuters. Metabolic CO2 output during bicycle commuting was ∼12 times less than that for a petrol car. In moderately active individuals, short-distance bicycle commuting at moderate intensity was associated, compared with car commuting, with positive effects on several physiological functions and environmental factors.
期刊介绍:
Experimental Physiology publishes research papers that report novel insights into homeostatic and adaptive responses in health, as well as those that further our understanding of pathophysiological mechanisms in disease. We encourage papers that embrace the journal’s orientation of translation and integration, including studies of the adaptive responses to exercise, acute and chronic environmental stressors, growth and aging, and diseases where integrative homeostatic mechanisms play a key role in the response to and evolution of the disease process. Examples of such diseases include hypertension, heart failure, hypoxic lung disease, endocrine and neurological disorders. We are also keen to publish research that has a translational aspect or clinical application. Comparative physiology work that can be applied to aid the understanding human physiology is also encouraged.
Manuscripts that report the use of bioinformatic, genomic, molecular, proteomic and cellular techniques to provide novel insights into integrative physiological and pathophysiological mechanisms are welcomed.
