Example Usage

Here’s how to use the FIT file functionality:

# Load a FIT file
fit_loader = load_fit_file('path/to/your/activity.fit')

# Extract raw power data
power_df = fit_loader.extract_power_data()
print(power_df.head())

# Compute MMP curve
durations, mmp_powers = fit_loader.compute_mmp_curve()

# Create MMP object directly from FIT file
mmp = mmp_from_fit('path/to/your/activity.fit')

# Create PDC object directly from FIT file
pdc = pdc_from_fit('path/to/your/activity.fit')

# Fit the power duration curve
result = pdc.fit()
print(result.best_values)
