如何使用「骑行消耗卡路里计算器（2024 体力活动纲要）」？How do I use the Calories Burned Biking Calculator (2024 Compendium) tool?
在「骑行消耗卡路里计算器（2024 体力活动纲要）」中，填写「骑行类型」、「平均速度」、「速度单位」、「体重」、「体重单位」等参数，结果会随输入实时计算并显示在下方。In the Calories Burned Biking Calculator (2024 Compendium): Fill in "Type of cycling", "Average speed", "Speed unit", "Body weight", "Weight unit"; results are recalculated instantly as you type.
怎么计算？How is it calculated?
千卡 = MET × 体重（kg）× 时长（小时）。MET 取自 2024 年《成人体力活动纲要》的骑行条目，例如 12–13.9 mph（19.3–22.4 km/h）为 8.0。70 kg 的人以 20 km/h 骑 1 小时约消耗 8.0 × 70 × 1 = 560 千卡。kcal = MET × body weight (kg) × duration (hours). The MET comes from the bicycling entries of the 2024 Adult Compendium of Physical Activities; 12–13.9 mph (19.3–22.4 km/h), for example, is 8.0. A 70 kg rider at 20 km/h for one hour burns about 8.0 × 70 × 1 = 560 kcal.
各速度的 MET 是多少？What MET does each speed use?
低于 10 mph：4.0；10–11.9 mph：6.8；12–13.9 mph：8.0；14–15.9 mph：10.0；16–19.9 mph：12.0；20 mph 及以上：16.8。山地车一般强度 8.5，室内单车一般强度 6.8。Below 10 mph: 4.0; 10–11.9 mph: 6.8; 12–13.9 mph: 8.0; 14–15.9 mph: 10.0; 16–19.9 mph: 12.0; 20 mph and above: 16.8. Mountain biking, general, is 8.5 and a stationary bike, general, is 6.8.
时长填 0 会怎样？What if the duration is 0?
结果就是 0 千卡，页面会说明；时长不能为负，最多 1,440 分钟（24 小时）。The result is simply 0 kcal and the page says so; the duration cannot be negative and is at most 1,440 minutes (24 hours).
能举个计算实例吗？Can you show a worked example?
例如在「骑行消耗卡路里计算器（2024 体力活动纲要）」中填 骑行类型 = 公路骑行（按速度），平均速度 = 20，速度单位 = km/h / km/h，体重 = 70，体重单位 = kg / kg，时长（分钟） = 60，结果区显示：速度：20 km/h · 12.43 mph；MET：8 · 12–13.9 mph（19.3–22.4 km/h）中等（代码 01030）；消耗：560 千卡（kcal）；每小时：560 千卡/小时；ℹ 估算值：实际消耗受坡度、风、体能和自行车而变化。For example, entering Type of cycling = Road cycling (by speed), Average speed = 20, Speed unit = km/h / km/h, Body weight = 70, Weight unit = kg / kg, Duration (minutes) = 60 in the Calories Burned Biking Calculator (2024 Compendium) gives: Speed: 20 km/h · 12.43 mph; MET: 8 · 12–13.9 mph (19.3–22.4 km/h), moderate effort (code 01030); Calories burned: 560 kcal; Per hour: 560 kcal/hour; ℹ An estimate: real energy use varies with gradient, wind, fitness and the bike.
哪些输入会被检查？Which inputs are validated?
「骑行消耗卡路里计算器（2024 体力活动纲要）」会检查这些输入——「平均速度」、「体重」：必须填写，须大于 0；「时长（分钟）」：所选方式用到时必须填写，不能为负数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Calories Burned Biking Calculator (2024 Compendium) checks its inputs — "Average speed", "Body weight": required, must be greater than 0; "Duration (minutes)": required when the chosen option uses it, cannot be negative; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「骑行消耗卡路里计算器（2024 体力活动纲要）」的设置：「骑行类型」可选 公路骑行（按速度）、山地车，一般强度（8.5 MET）、室内单车，一般强度（6.8 MET）（默认 公路骑行（按速度））；「平均速度」默认 20；「速度单位」可选 km/h / km/h、mph / mph（默认 km/h / km/h）；「体重」默认 70；「体重单位」可选 kg / kg、lb / lb（默认 kg / kg）；「时长（分钟）」默认 60。每次生成结果都按当前设置处理。Settings in the Calories Burned Biking Calculator (2024 Compendium) — "Type of cycling": Road cycling (by speed), Mountain biking, general (8.5 MET), Stationary bike, general (6.8 MET) (default Road cycling (by speed)); "Average speed" default 20; "Speed unit": km/h / km/h, mph / mph (default km/h / km/h); "Body weight" default 70; "Weight unit": kg / kg, lb / lb (default kg / kg); "Duration (minutes)" default 60. The result always uses the current settings.
结果可以代替医生的建议吗？Can this replace medical advice?
不能。「骑行消耗卡路里计算器（2024 体力活动纲要）」基于常用公式给出估算，个体差异较大，如有健康问题请咨询医生或专业人士。No. The Calories Burned Biking Calculator (2024 Compendium) gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
