Task 9

Training intensity

Heart rate is a popular metric used to measure training intensity. Depending on age and fitness level, heart rates are grouped into different zones that people can target depending on training goals. A target heart rate during moderate-intensity activities is about 50-70% of maximum heart rate, while during vigorous physical activity it’s about 70-85% of maximum.

We'll create a distribution plot of my heart rate data by training intensity. It will be a visual presentation for the number of activities from predefined training zones.

Create a customized histogram for heart rate distribution.

• Subset df_run from March 2015 through 2018 then select the Average Heart Rate (bpm) column. Assign the result to df_run_hr_all.

• Create a plot with plt.subplots(), setting figsize to (8,5). Assign the result to fig, ax.

• Create customized x-axis ticks with ax.set_xticklabels(). Set the parameters labels to zone_names, rotation to -30, and ha to 'left'.

• Show the plot with plt.show().
