Jonathan Wolfe:本期节目讨论了有氧运动的最佳方式,特别是针对时间有限的忙碌人士。我们采访了Javier Gonzalez教授,探讨了高强度间歇训练(HIIT)和传统耐力训练的优缺点,以及如何根据个人情况调整运动强度、持续时间和频率。 Javier Gonzalez教授详细解释了VO2 max的概念及其重要性,并指出心肺健康程度是预测心血管疾病风险和整体死亡率的关键指标。他强调,任何运动都比不运动好,运动量越大越好。对于时间有限的人,教授建议可以采用高强度间歇训练,例如每周进行6次10-20秒的短跑,就能在两个月内提高近10%的体能。 此外,教授还讨论了低强度运动的益处,例如简单的活动,也能带来一些健康益处。他指出,即使是低强度运动,例如散步、骑自行车等,也能降低死亡风险;高强度运动效果更好。教授建议根据个人喜好和时间安排,选择高强度短时间运动或低强度长时间运动,并强调在日常生活中增加活动量,例如爬楼梯等。 Javier Gonzalez:本期节目主要探讨了有氧运动的最佳方式,以及如何根据个人情况调整运动强度、持续时间和频率以达到最佳的健康益处。我解释了VO2 max的概念,以及它作为衡量心肺健康的重要指标。研究表明,高强度间歇训练(HIIT)和传统耐力训练都能提高VO2 max,但HIIT效果更好,因为运动强度可以替代运动时长。 对于时间有限的人,我建议可以采用高强度间歇训练,例如每周进行6次10-20秒的短跑,就能在两个月内提高近10%的体能。当然,如果时间充裕,低强度运动,例如散步、骑自行车等,也能带来显著的健康益处,并降低死亡风险。 我强调,任何运动都比不运动好,运动量越大越好。重要的是找到适合自己的运动方式,并将其融入日常生活。居家办公可能导致运动量减少,因此建议有意识地增加日常活动量,例如爬楼梯等。

Chapters
Cardio exercise, or aerobic exercise, includes activities like jogging and hiking, which utilize the cardiovascular and cardiorespiratory systems. Unlike strength training, cardio focuses on improving the capacity of the heart and muscles to use oxygen.

Shownotes Transcript

Not all of us want to go to the gym 5 times a week, but what if there was a way to do quick, short high intensity 20 second exercises and still reap benefits - or does that sound too good to be true?

Javier and Jonathan break this down as they look at recent studies and results, optimizing exercise routines to achieve the desired health benefits, taking into account factors like intensity, duration, and frequency as well as discussing the effect of working from home vs commuting to the office.
