Abstract

Eight (five men, three women) untrained, healthy subjects (age = 22.4 ± 2.7 years, height = 172.8 ± 10.0 cm, weight = 75.26 ± 18.35 kg) participated in an 8-week strength training program. Prior to and following the program, subjects were evaluated during a 10-minute, submaximal, constant-velocity treadmill test at approximately 80% of V̇O2peak. Although leg press one repetition maximum (1RM) weight improved (163.93 ± 63.16 kg pretraining to 209.37 ± 69.18 kg posttraining), no significant changes were observed during the test for V̇O2 at minute 3 (2.50 ± 0.58 L·min-1 pretraining and 2.49 ± 0.58 L·min-1 posttraining), end-exercise V̇O2 (2.80 ± 0.67 and 2.75 ± 0.60, pre- and posttraining, respectively), the slow component of V̇O2 (the change from minute 3 to end exercise; 306 ± 141 ml·min-1 pretraining, 274 ± 98 ml·min-1 posttraining), or end-exercise blood lactate concentration (4.64 ± 1.29 mM pretraining, 4.84 ± 1.98 mM posttraining). Maximum velocity (177.5 ± 37.3 m·min-1 pretraining, 187.5 ± 35.8 m·min-1 posttraining) and test time (15.16 ± 2.90 min pretraining and 16.22 ±2.84 min posttraining) during an incremental, maximal treadmill test both improved without any change in V̇O2peak (38.85 ± 10.18 ml·kg-1·min-1 pretraining, 39.44 ± 8.35 ml·kg-1·min-1 posttraining). Results of the present study suggest that an 8-week strength training program does not significantly improve running economy or attenuate the slow component of V̇O2 in untrained subjects.
