| ABSTRACT | |||
| This study investigated if there were acute interference effects
of strength exercises on subsequent continuous and intermittent 5Km aerobic
exercises. Eleven physically active males (23.1 ± 3.1 yrs, 1.75 ± 0.07 m,
70.5 ± 8.8 kg, and 58.2 ± 8.3 VO2max) performed the following
experimental sessions: A) 5 sets of 5 RM on the leg press followed by a
5km run performed continuously (average velocity of the first and second
ventilatory thresholds, vΔ50), B) 5
sets of 5 RM on the leg press followed by a 5km run performed intermittently
(1 min run at the vVO2max : 1 min of rest); C) 2 sets of 15 RM
on the leg press followed by a 5km continuous run; and D) 2 sets of 15 RM
on the leg press followed by a 5km intermittent run. Heart rate, blood lactate
concentration, rate of perceived exertion, and VO2 at the first
and the fifth km were considered for statistical purposes. There were no
significant effects of both strength bouts on any of the variables associated
with endurance performance (p > 0.05). It seems that both maximum and
strength endurance bouts do not acutely impair aerobic performance. Key words: Running, concurrent training, interference effect, ratings of perceived exertion, oxygen consumption. |
