Fig. 4

Patterns of adherence to resistance and endurance training frequency, intensity, time, and type for participants randomised to high intensity training (n = 288). NB. Each’slice’ of the figure represents the proportion of participants with a specific combination of adherence levels for the four FITT principles, for example, 18.8% of participants had 0–25% adherence to all four FITT principles for resistance training, while 3.5% of participants had 0–25% adherence to the prescribed resistance training frequency but 75–100% adherence to the prescribed resistance training intensity, time and type. Blue segments represent 0–25% adherence, orange segments represent > 25–50% adherence, grey segments represent > 50–75% adherence, and yellow segments represent > 75–100% adherence
