The PAR scores in the treadmill-trained group
improved by 48 MET hr/wk (p < 0.05) after 12
weeks of training (Table III). After a total of 24
weeks of treadmill training PAR scores remained
elevated over baseline values. No changes in the PAR
scores were observed in either the strength-trained or
control groups after 12 weeks. In addition, no
changes in PAR scores were found in the subjects
who received treadmill training after strength training
or in the combined training group.
