Abstract The purpose of the investigation was to determine whether low-intensity continuous (LSD) or high-intensity interval (INT) endurance activity prior to isokinetic strength assessment reduced torques generated 0.52 rad (30°) prior to horizontal (T30). T30was measured at 10 contractile speeds (0.52-5.20 rad s-1) prior to and following the LSD and INT exercise bouts. Six males (23.2 ±3.3 yrs, 74.9 ±6.8 kg, 177.6 ±5.4 cm) with a mean peak cycle ergometer oxygen consumption (PCE VO2) of 3.85 (±0.33) Lmin-1completed 150 min cycling at 35% PCE VO2in the LSD challenge. The 5 females and 3 males (20.8 +4.6 yrs, 63.2 ±12.0 kg, 168.8 ±8.5 cm, 2.51 ±0.78 L min-1) of the INT condition completed five 5-min repetitions in which the work rate was progressively increased from 40 to 100% PCE VO2. Both the LSD and INT regimens reduced T30at all contractile speeds. The reduction in T30was similarly small for the LSD and INT conditions when expressed as percentage of preintervention values and effect sizes. Small, acute reductions in strength as a result of temporally proximal endurance activity may partially explain the inhibition in strength development that has followed some concurrent strength and endurance training investigations.
