The current study examined the adaptive response to both endurance END and sprint interval training SIT in a group of twenty-one recreationally active adults. All participants completed three weeks four days- week of both END 30 minutes at ~65% VO2peak work rate WR and SIT eight, 20-second intervals at ~170% VO2peak WR separated by 10 seconds of active rest following a randomized crossover study design with a three-month washout period between training interventions. While a main effect of training was observed for VO2peak, lactate threshold, and submaximal heart rate HR, considerable variability was observed in the individual responses to both END and SIT. No significant positive relationships were observed between END and SIT for individual changes in any variable. Non-responses were determined using two times the typical error TE of measurement for VO2peak 0.107 L-min, lactate threshold 15.7 W, and submaximal HR 10.7bpm. Non-responders in VO2peak, lactate threshold, and submaximal HR were observed following both END and SIT, however, the individual patterns of response differed following END and SIT. Interestingly, all individuals responded in at least one variable when exposed to both END and SIT. These results suggest that the individual response to exercise training is highly variable following different training protocols and that the incidence of non-response to exercise training may be reduced by changing the training stimulus for non-responders to three weeks of END or SIT.
