Abstract

Metabolic, hormonal and neurological responses to four bouts of lower or upper body resistance exercise preceded by cycle ergometry or rest were assessed. Nine resistance trained men (26.7±6.6 years) underwent bouts of 1) cycle ergometry then bench press, 2) bench press only, 3) cycle ergometry then back squat 4) back squat only. Cycle ergometry was performed at 75% maximum heart rate for 45 minutes. Bench press and back squat protocols required six sets to volitional fatigue at 80% one repetition maximum with two minutes rest between sets. No physiological differences were noted (p>0.05) SIgnificantly more repetitions were performed during set one only for back squat without preceding aerobic exercise (12.6±4.5 vs. 10.0±3.5, p=0.000) and cumulatively at set three (27.1±10.6 vs. 23.1±9.2, p=0.014), no differences were noted for bench press repetitions. Cycle ergometry results in impaired back squat, but not bench press performance, however, the mechanisms of performance decrement are still unknown.
