Delayed Muscle Soreness

Why does it hurt a day or 2 later?

There are two types of exercise-related muscle soreness. Immediate muscle soreness quickly dissipates and is the pain you feel during, or immediately after, exercise. Delayed muscle soreness manifests 24 to 48 hours after the exercise session and spontaneously decreases after 72 hours.

The most current research attributes it to microscopic tears in the muscle and surrounding connective tissue following eccentric exercise. (A muscle contracts eccentrically when it lengthens under tension during exercise).

Those who experience delayed muscle soreness include conditioned individuals who increase the intensity, frequency or duration of their workouts, or participate in an activity that they are unfamiliar with. Beginning exercisers, or those who have undergone a significant lapse in training,frequently experience soreness when starting a new exercise program.

Once you induce delayed onset muscle soreness at a specific exercise intensity, you shouldn't experience that sensation again until intensity is increased. This is because delayed muscle soreness has been shown to produce a rapid adaptation response, which means that the muscles adapt to an exercise intensity.

Experts Predict Hip-Fracture Epidemic

Better nutrition, treatment now could prevent global crisis

FRIDAY, June 16 (HealthDay News) -- The world faces an epidemic of hip fractures over the next few decades as more and more people's bones weaken from osteoporosis as they age.

So conclude researchers who estimate that at least 6.3 million people worldwide will suffer a hip fracture in the year 2050 -- more than triple the 1.7 million cases recorded in 1990.

The trend toward more fractures could be turned around, however, if doctors and the public take advantage of what's known about osteoporosis prevention. One key preventive strategy: "We should be looking at the younger population to maximize calcium," said Dr. Joseph Fetto, associate professor of orthopedics at the New York University Hospital for Joint Diseases.

NOTE: This is another reason why training for balance and stabilization is very important, particularly for adults past 50 and 60 years old.

Eating and Exercise: Time it Right to Maximize Your Workout

When you eat and what you eat can affect your performance and the way you feel during your workout. To get the most from your workout, follow these guidelines:

•Wake up early enough to eat a full breakfast. "Most of the energy you got from dinner last night is used up by morning," says Stephen DeBoer, a registered dietitian at Mayo Clinic, Rochester, Minn. This. "Your blood sugar is low. If you don't eat, you may feel sluggish or lightheaded while exercising." If you plan to exercise within an hour after breakfast, eat a smaller breakfast or drink something to raise your blood sugar, such as a sports drink.
•Time your meals. Eat large meals at least three to four hours before exercising. If you're having a small meal, eat two to three hours before exercising.
•Don't skip meals. Skipping meals may cause low blood sugar, which can make you feel weak and lightheaded.
•Eat after your workout. To help your muscles recover and to replace their glycogen stores, eat a meal that contains both protein and carbohydrates within two hours of your exercise session if possible.

What to eat: Getting the right fuel for your best performance
Carbohydrates: Your body's chief source of fuel Your body stores excess carbohydrates as glycogen — primarily in your muscles and liver. Your muscles rely on stored glycogen for energy. Cereals, breads, vegetables, pasta, rice and fruit are good carbohydrate sources. But right before an intense workout, avoid carbohydrates high in fiber, they may give you gas or cause cramping. If you don't like to eat solid foods before exercising, drink your carbohydrates in sports beverages or fruit juices. If you're a long-distance runner or you exercise for long periods of time, you might want to consume more carbohydrates regularly and consider carbohydrate loading before a big athletic event.
Protein and fats: Important, but not your body's top fuel choice Protein isn't your body's food of choice for fueling exercise, but it does play a role in muscle repair and growth. Fat is an important, although smaller, part of your diet. Fats, along with carbohydrates, provide fuel for your muscles during exercise. Try to get most of your fat from unsaturated sources such as nuts, fatty fish or vegetable oils. Avoid fatty foods just before exercising
Water: Drink plenty to avoid dehydration The American College of Sports Medicine recommends that you drink 8 glasses of water every day and more when the temperature and humidity are high. Drink at least one glass of water before and after your workout and every 10 to 15 minutes during your workout to replace fluid lost in perspiration. Avoid substituting water with coffee, tea or soda, because they contain caffeine, which acts as a diuretic, a substance that causes your body to lose even more water.
Water is generally the best way to replace lost fluid, unless you're exercising for more than 60 minutes. In that case, sip a sports drink to help maintain your electrolyte balance and give you a bit more energy from the carbohydrates in it.

Warm Up to Work Out

from the American Council on Exercise
ACE asks "Suppose you were told that you only had to add an extra five to 10 minutes to each of your workouts in order to prevent injury and lessen fatigue. Would you do it?" Those few extra minutes are called a warm-up.
A gradual warm-up:- Leads to efficient calorie burning by increasing your core body temperature - Produces faster, more forceful muscle contractions - Increases your metabolic rate so oxygen is delivered to the working muscles more quickly - Prevents injuries by improving the elasticity of your muscles - Gives you better muscle control by speeding up your neural message pathways to the muscles - Allows you to work out comfortably longer because all your energy systems are able to adjust to exercise, preventing the buildup of lactic acid in the blood - Improves joint range of motion - Psychologically prepares you for higher intensities by increasing your arousal and focus on exercise
Your warm-up should consist of two phases: 1) progressive aerobic activity that utilizes the muscles you will be using during your workout, and 2) flexibility exercises. Stretching muscles after warming them up with low-intensity aerobic activity will produce a better stretch since the rise in muscle temperature and circulation increases muscle elasticity, making them more pliable.

The Best Butt Exercises

New Research from the American Council on Exercise on the Most Effective Exercise for your Glutes

Quadruped Hip Extensions - On your hands and knees, slightly contract your abdominals to stabilize your torso and spine. Lift one leg up, keeping the knee bent at 90 degrees. Lift the leg until the bottom of the foot is pointing toward the ceiling and the leg is lined up with the body. Repeat on the same side for eight to 12 reps. Change legs.
Step-Ups - Stand with good posture behind a tall step or box [approximately 15 inches (38 cm) high] while holding a dumbbell in each hand. Place your left foot on top and transfer your weight to that leg. Push down with your left foot (especially the heel), straightening your leg, to come up on top of the box. Use the left leg only; keep the right leg passive, especially as you initiate the step-up. Repeat on the same side for eight to 12 reps. Change legs.
Lunges - Hold a dumbbell in each hand, standing tall with good posture. Step forward with the right foot, keeping the head up and spine neutral. Drop your left knee toward the floor by bending knees, making sure to keep the front heel down and the knee directly over the center of the foot. Push down and forward through your heel to return to the starting position. Repeat on the other side, alternating for eight to 12 reps per side.
Four-Way Hip Extensions - Stand upright and grasp the stabilizing bar of the machine. The resistance pad should be placed at the knee on the back side of the exercising leg. Move your thigh to the rear until your hip is fully extended backward. Repeat for 8 to 12 reps and change sides.

Interval training: Can it boost your calorie-burning power?

Do you wish you could burn more calories without spending more time at the gym? Consider aerobic interval training.
Interval training is simply alternating bursts of intense activity with intervals of lighter activity.

You'll burn more calories.
You'll improve your aerobic capacity.
You'll keep boredom at bay.
You don't need special equipment.

After warming up, you might increase the intensity for 30 seconds and then resume your normal pace. The next burst of more intense activity may last two to three minutes. "The intervals can vary throughout your workout," says Tom Allison, Ph.D., an exercise physiologist at Mayo Clinic, Rochester, Minn.. "How much you pick up the pace, how often and for how long is up to you." A personal trainer or other expert can help you time the intensity and duration of your intervals based on your target heart rate, the ability of your heart and lungs to deliver oxygen to your muscles (peak oxygen intake) and other factors.

Interval training isn't appropriate for everyone. If you have a chronic health condition or haven't been exercising regularly, consult your doctor before trying any type of interval training. Also keep the risk of overuse injury in mind. If you rush into a strenuous workout before your body is ready, you may hurt your muscles, tendons or bones. Instead, start slowly. Try just one or two higher intensity intervals during each workout at first. If you think you're overdoing it, slow down.

When To Replace Training Shoes?

Every 3-6 months or 300-500 miles
One of the first questions I ask a runner or walker who complains of aches such as shin splints, knee pain or foot pain is how old their running shoes are. When you run, every time you land your shoes absorb 3 to 5 times the weight of your body. Over time, the cushioning breaks down and instead of the shoes absorbing this impact, it is absorbed by your joints and muscles.
Sweat, heat and time also cause the shoes to lose some of their cushioning and resiliency - so getting a good deal on a closeout shoe that has been sitting in a warehouse for 2 years may not be a bargain over the long run. If you have been working out indoors all winter, the shoes may look great but the cushioning is probably worn down. Some of us develop an emotional attachment to their sneakers - a model or color that has gone out of production, a pair of shoes that they ran a great race in, or in some cases an attachment to the idea that they haven’t fallen apart so they must be okay. Go ahead, trade them in, you’ll feel so much better that you’ll forget about them in no time at all.
The American Podiatric Medical Association recommends that you trade in your trainers every 300-500 miles or 3-6 months. They also suggest rotating 2 or more pairs of shoes, which gives shoes a chance to breathe and to recover their cushioning properties in between use. They have some helpful tips on how to find the right pair of sneakers, cli ck here to read more.

Slow Burn: How Aging Affects Metabolism

by Marin Gazzaniga for MSN Health & Fitness
If you think you’ve put on a few extra pounds because your metabolism has slowed down, you may be only half right. Barry Stein of Wake Forest University School of Medicine is writing a book about staying fit after 50. As he explains, “As we age, we are subject to sarcopenia—muscle wasting. Since muscle burns more energy than fat, this means the metabolic load goes down and metabolism reflects that.” That is, if you do nothing about your loss of muscle with age, it will take you longer to burn off a candy bar at age 60 than at 20.

Twins Tammy and Lyssie Lakotos, authors of Fire Up Your Metabolism, recommend both cardiovascular activity and weight training. “Cardiovascular activity burns calories while you do it. Additionally, you could burn about 20-30 additional calories afterwards, which may not seem like a big amount daily, but adds up over a lifetime,” says Tammy Lakotos. Strength training is effective long after you’ve put down the barbells because muscle burns more calories than fat while you’re at rest.

What's a TransFat?

An overview from the American Heart Association
Trans fat (also called trans fatty acids) is formed when liquid vegetable oils go through a chemical process called hydrogenation, in which hydrogen is added to make the oils more solid. Hydrogenated vegetable fats are used by food processors because they allow longer shelf-life and give food desirable taste, shape, and texture. Evidence suggests that consumption of trans fat raises LDL (“bad”) cholesterol levels and lowers HDL (“good”) cholesterol levels, causing the arteries to become clogged and increasing the risk of developing heart disease and stroke.
