Key result
Two prior maximal isometric contractions cut peak contralateral muscle soreness ~32% following maximal eccentric exercise.
Why the study?
Muscle damage after maximal eccentric contractions is reduced by prior isometric contractions in the same arm, but the effect of prior isometric contractions in the opposite arm was unclear.
Does performing two maximal voluntary isometric contractions (2MVIC) attenuate muscle damage after 30 maximal eccentric contractions (30MVEC) performed by the opposite arm in untrained young men?
Comparison
2MVIC performed 1, 2, 4, or 7 days before 30MVEC by opposite arm vs 30MVEC only control

May attenuate contralateral soreness after eccentric exercise in untrained men; hypothesis-generating and requires prospective validation before any clinical use.

Absolute Event Rate: 45% vs 66%
p-value: p=< .05
Performing two maximal isometric contractions 1-2 days prior to maximal eccentric exercise by the contralateral arm reduces muscle damage.
Chen et al. (2017) studied Muscle damage (n=65). Two maximal voluntary isometric contractions (2MVIC) vs. 30 maximal eccentric contractions (30MVEC) only was evaluated on Peak muscle soreness (p=< .05). Two maximal voluntary isometric contractions performed 1-2 days prior significantly reduced peak muscle soreness after 30 maximal eccentric contractions of the contralateral arm (45-46 mm vs 66 mm; P<.05).
