Almonds to the Rescue!

/in /by

Delayed-onset muscle soreness (DOMS) is common in sedentary people who overdo it—the weekend warriors who catch up on all the yard work in one day or people who have to shovel out a long driveway after a big snow. Researchers wanted to test what benefits these occasional exercisers may get from eating almonds compared to a cereal bar.

Researchers recruited a group of sedentary volunteers between the ages of 30 and 65. They wanted to examine the effect of eating two ounces of almonds every day for four weeks on measures of pro-inflammatory hormones and oxylipins, which are oxidized fats that can have pro- or anti-inflammatory effects. The control group ate a cereal bar with the same caloric content.

After 28 days, all subjects performed a 90-minute workout session designed to damage muscle that included a bout of maximal aerobic exercise, weight training, jumping, and other activities. Did they damage their muscles? Absolutely, based on the blood levels of enzymes indicating DOMS as well as standardized questionnaires assessing pain after exercise. The subjects who ate almonds every day had more anti-inflammatory oxylipins after exercise while the controls had an increase in pro-inflammatory oxylipins. Most important, the almond eaters appeared to recover a little faster.

Almond skins are a treasure of phenolic compounds. While this was a small study (69 total subjects), there were benefits to eating almonds every day for non-exercising weekend warriors. Could other high-phenolic foods have the same benefit? Time will tell. Almonds are also a treasure trove of omega-3 fatty acids, fiber, and protein, so substituting almonds for some other snack may prove beneficial. How about you regular exercisers? I’m betting you’ll get some benefit as well. It’s all part of eating better.

Dealing with Delayed-Onset Muscle Soreness

/in /by

Muscle soreness generally occurs after a new workout routine, especially weight training. It generally involves eccentric contractions: the simplest way to explain it is the resistance to a movement. During a bicep curl, eccentric contractions would be resisting the lowering of the weight as you return to the starting position. But that’s not exactly what I mean. This is an overall fatigue and soreness that affects more than muscle. Let’s call it delayed-onset body soreness.

What Causes Delayed-Onset Body Soreness?

Movements that are repetitive, that last for hours, that aren’t part of your normal routine—those are the likely causes of delayed-onset soreness. It doesn’t matter how fit you are or how strong you are. While fitness and strength will help, it’s still going to happen occasionally. When you perform movements, even if they’re as simple as standing and answering questions like I did, there are stresses on the ligaments, tendons, and joints as well as the muscles, minute after minute, hour after hour. Micro-tears can occur in multiple types of tissue, and that can cause inflammation and pain.

What you feel the next day is actually the repair process in progress.

Can You Prevent DOBS?

Probably not because it’s caused by something you do infrequently: rake leaves, walk up and down arena steps, shovel snow, or help someone move. But stretching on a regular basis probably helps. Ever stand up, take a deep breath, and reach over your head to stretch just about every muscle in your body? Something as simple as that a few times a day will help keep you limber. Yoga would be great but whatever it is, it has to be consistent to be effective.

The Bottom Line

Infrequent events with repetitive movements are going to happen. I don’t think there’s a need to specifically train for them other than stretching on a regular basis. Taking nutrients such as glucosamine and vitamin C may help the repair process; you can take them in the days leading up to the event as well as after, along with whatever pain meds work best for you. No question that regular aerobic exercise and strength training will help, but most likely won’t prevent soreness. The good news is that this is a problem that should resolve itself quickly.

What Did I Do?

Fall is here and those wonderful multi-colored leaves everyone seems to love are making their appearance here in Michigan. While they can be stunning to look at, they will need to be raked and recycled. That’s going to lead to people waking up the next day (or days because they all don’t drop on the same day) feeling like they’ve been run over by a truck. Sore. Fatigued. Hard to move.

Recently Paula was on a mission to find a specific item so we went to six different big box stores in one afternoon, which is something we hadn’t done since before covid. She felt fine and made it through the day but was wiped out the next day. I just spent the weekend in St. Louis with a few thousand of my closest friends talking and answering questions. Both days I was wiped out and went to bed early. Ever help someone move? Remember how you felt the next day? You ask yourself, “What did I do?”

The technical term is delayed-onset muscle soreness. I think it’s really more than just muscles involved. The question is why? Raking leaves and walking through stores isn’t strenuous. Neither is standing and talking. What gives? Any time a task requires repetitive movements you’re not used to doing, you’re at risk for delayed-onset muscle soreness. I’ll talk about how to deal with it on Saturday.
