Abstract

This study aimed to determine whether high-intensity dumbbell exercise involving both concentric and eccentric contractions would provide a temporary alleviation of delayed-onset muscle soreness (DOMS). It also examined the effect of alleviated muscle soreness on dynamic muscle performance using a stretch-shortening cycle (SSC; peak angular acceleration and velocity of the elbow during both lowering and concentric phases) to provide indirect evidence that DOMS contributes to the dynamic performance decrement after eccentric injury. Thirteen untrained adults performed 30 maximal isokinetic eccentric contractions of the elbow flexors to induce eccentric damage. Five sets of arm curls using a dumbbell (equivalent to 70% of isometric maximal voluntary contraction) were then performed until failure on days 1, 2, 3, and 5 of recovery. Muscle soreness significantly decreased after each session of dumbbell exercise (p = 0.001). Isometric strength further decreased immediately after dumbbell exercise, indicating muscle fatigue (p < 0.001). Dynamic performance variables were less affected by fatigue, however, with performance being reduced only for peak lowering velocity (p < 0.001). Other measures of dynamic performance were relatively constant after dumbbell exercise, particularly on days 2 and 3 when soreness was greatest. It was concluded that high-intensity concentric/eccentric dumbbell exercise was able to temporarily alleviate DOMS and that this reduction in soreness served to counter the effect of peripheral muscle fatigue during dynamic activities. Practical applications of this study are that after eccentric damage, alleviation of muscle soreness through an optimal warm-up may be helpful to temporarily recover dynamic muscle performance. Free-weight loading is one suggested technique to temporarily manage DOMS.

Can't embed cause I found it on ESPN and they're tricky. But that photo is amazing.

hey lbss, wats with the foot xray? you fractured your 5th metatarsal tuberosity?

Nope, arthritis in the metacarpophalangeal joint of the great toe. AKA hallux rigidus. Plus a bone spur up top there, which you can see. Used to just be the left foot, now it's both.

Do-Wins. Grey. I'll get a vid up soon cause I got my new DROID! Sweet.

Tonight, soreness in pecs and lats. Kept it nice and easy, feel pretty good now. If experience is any guide, will be more sore tomorrow. Oh well.

warm up
light foam roll, 5-6 mins
light stretching

work
jump rope x100,100,100,50,50
row x15 mins, easy pace
jump rope x50,50,50,50

cool down
stretch

powerlifting ignorance question: Why didn't you go for a lighter final attempt on DL? Like 740 or something?

                 

Thanks for the props, guys!

Tomorrow begins adarq plan numba 1, with my new shoes that just came. Sweet.

EDIT: This is a bit silly, but the shoes have me absolutely champing at the bit to go work out. I can't wait to see what squats are like with real shoes on instead of elevating my heels on little plates.

COB tomorrow cannot come soon enough. Might even try to dip out of work a little bit early (boss is in Egypt).

warm up
shoot hoops -- nice
sprinter's warm ups
submax 1-step jump x2 -- got 30 easily on the first one and knew this was going to be a good day

work
sprint x4x15y
full run up x3x5 -- first jump was a PR, definitely 32 and maybe a bit more, everything was over 30.5 and a bunch were 31.5, might have gotten another 32 or two, as well
MR half tuck 3x10 -- legs/CNS dead
SS x3 (couple reps shy of TF/AF)
--dips x10
--pullups x8,7,7

cool down
foam roll x30 mins
stretch x30 mins

Helped an older guy who was trying to learn how to roll. Like helping people with stuff.
