at 3 submaximal heartrates (HRs). Exercise modalities were arm cranking (AC), rowing (R), tr eadmill walking (TW), and bicycling (B);
and selected HRs were 100, 125 and 150 beatslmin. Each S participated in 3 exercise sessions, each to a different target HR and consisting
of 4 exercise bouts (1 on each exercise modality) alternating with rest periods.
