N2 - The effects of exercise-induced muscle damage
(EIMD) on the physiological, metabolic and perceptual
responses during upper body arm cranking exercise are
unknown. Nine physically active male participants performed
6 min of arm cranking exercise at ventilatory
threshold (VT), followed by a time to exhaustion (TTE)
trial at a workload corresponding to 80 % of the difference
between VT and _V O2peak 48 h after bench pressing exercise
(10 9 6 repetitions at 70 % one repetition maximum) or
20 min sitting (control). Reductions in isokinetic strength
and increased muscle soreness of the elbow flexors and
extensors were evident at 24 and 48 h after bench pressing
exercise (P\0.05). Despite no change in _V O2, _VE, HR
and blood lactate concentration ([Bla]) between conditions
(P[0.05), rating of perceived exertion (RPE) was higher
during the 6 min arm cranking after bench pressing exercise
compared to the control condition (P\0.05). TTE
was reduced in the treatment condition (207.2 ± 91.9 cf.
293.4 ± 75.6 s; P\0.05), as were end _V O2 (P\0.05)
and [Bla] at 0, 5 and 10 min after exercise (P\0.05). RPE
during the TTE trial was higher after bench pressing
(P\0.05), although end RPE was not different between
conditions (P[0.05). This study provides evidence that
EIMD caused by bench pressing exercise increases the
sense of effort during arm cranking exercise that leads to a
reduced exercise tolerance. The findings have implications for individuals participating in concurrent endurance and
resistance training of the upper body.
