Altitude refers to the vertical distance or height difference between a specific point on the ground and sea level.
The higher the altitude, the thinner the air and the lower the air pressure.
Changes in altitude can affect exercise and training, and some athletes engage in high-altitude training to enhance performance.
Unit: meter.
Cumulative ascent/descent
Cumulative ascent refers to the sum of all uphill elevation gains throughout the entire activity, representing the total climbing distance along the route. Cumulative descent refers to the sum of all downhill elevation losses, representing the total drop along the route.
For example, if you climb from an elevation of 0 meters to 300 meters, descend back to 0 meters, and then climb to 350 meters, the cumulative ascent is 650 meters and the cumulative descent is 300 meters.
Unit: meter.
Gradient
Gradient refers to the ratio of vertical elevation change to horizontal distance during an activity. Uphill sections are shown as positive values, while downhill sections are shown as negative values.
Vertical speed
Vertical speed refers to the speed in the vertical direction during ascent or descent.
During climbing, you can understand your current training intensity based on it. It is used in the same way as speed or power on flat ground.
