How Exercise Affects Your Body

Your entire body is put under stress during a workout. Each body system fires in its own unique way in unison to keep pushing. Quite simply put, you might think of exercise as a controlled practice of breaking your body down to rebuild stronger.

With each repetition, your muscle tissues are breaking down, releasing byproducts that stimulate your energy systems for sustained effort. We need this to keep moving, once we’ve used up our initial ATP Phosphocreatine and glycogen.

In recovery phases, these byproducts of lactate contribute to growth responses at the cellular level. Through the process of rebuilding, in recovery, our body utilizes nutrition, sleep, and hydration to “fortify” itself. It is amazing the adaptations the human body can make to a stimulus it is exposed to.

We also see with weight training or impact loading in aerobic exercises, that our bones have little cells called osteocytes that calcify and contribute to denser bone structures. All processes in your entire body are affected by physical activity, but the adaptations I mentioned are only optimal when we fuel our bodies correctly.

Why You Might Not Be Making “Gains”

Let me ask you this… How much do you eat every day? How much are you sleeping every night?

If you answered conservatively or with a low estimate of calories per day, that is your first issue. To gain muscle mass, or any mass, a surplus of daily calories is ideal. That isn’t eating the maintenance level of calories per day; that is eating above that range.

Prioritizing healthy and nutrient-dense food options may be an obvious thing for some. Assuming you do not have special dietary considerations, you might look at a macromodel of nutrition.

Understanding the Macromodel of Nutrition

The macromodel of nutrition is a generalized diet practice incorporating an emphasis on the content of major macromolecules in our foods. Carbs, Proteins, and Fats are the Macromolecules that our body utilizes.

Daily Caloric Split (Macromodel Example):

• Carbohydrates: 45–65%

• Proteins: 10–35%

• Fats: 10–25%

Carbohydrates: Fuel Your Activities

Carbohydrates consist of an average of 45-65% of our total caloric intake per day. These molecules can be simple and complex. Simple carbs are found in sugar, bread, fruits, and quickly digested foods. Complex carbs consist of starches, vegetables, legumes, and fibrous options. Complex carbs take longer to digest, but keep the body fueled for sustained effort due to a generally higher caloric content.

The positive aspect of simple carbohydrates is that they offer quick energy with less time to digest and offer availability in our tissues for rapid use. The drawback of simple carbs is that they hike up our blood sugar, which puts a higher glycemic load on the body. In a healthy individual, that is fine and could offer recovery benefits if training (paired with protein), because they have a healthy insulin response to this sudden sugar spike. The sugar gets to our muscles and “where it needs to go” with insulin release from our liver. In an older individual or an individual with compromised energy systems, such as diabetes and metabolic conditions, it may be better to favor more complex carbs that slow digestion and the release of sugar due to the fiber content.

For the general person, the main consideration for training days would be windows of digestion and bioavailability. Typically, 2-3 hours would be a good timeframe before training to prioritize your simpler sugars. Beyond that, 3-5 hours before exercise would emphasize complex carbohydrates. For example, when you train legs at 4 pm, you might look at a 12 pm lunch with a fibrous salad and lean protein. At 3 pm, you may eat an apple for a quick pick-me-up before your squats. You allow that digestion time for fibrous foods in advance and rely on the quick, simple carbs before your higher activity level. 

Fats (Lipids): Essential and Beneficial

Many people are misinformed by thinking that limiting fats in their diet is “healthy” is good, but this is a nuanced subject. Fats (Lipids) support our health more related to sustained low-intensity activities, cellular function, and hormonal responses. We need an essential level of fat stored on our bodies to allow for healthy bodily functions. Our body can convert excess energy into body fat from other macromolecules like carbs and proteins, when eating those in surplus as well.

Don’t shy away or eliminate fat in your diet, because it is necessary for your health and functioning. In a macromodel meal plan, you might prioritize 10-25% of your diet to involve a balance of saturated animal fats and unsaturated fats such as nuts, olive oil, avocados, and chia seeds.

Saturated fats can be moderately consumed by healthy individuals with well-regulated metabolism and regular physical activity. However, when eaten in excess amounts regularly in our diet, it may be connected to endothelial dysfunction and, in the long term, may contribute to atherosclerosis. This happens when the endothelial layer (inside walls of our blood vessels and capillaries are unable to release Nitric oxide as effectively to dilate. The reduced endothelial function leads to the formation of superoxide and oxidative stressors, which, over time, can lead to heart disease. Continued moderate to high intensity aerobic activity is one way to protect against the oxidative stress caused by excess fats in our diet.

One consideration before exercise would be to avoid high-fat content in your food choices before exercise, because it may negatively affect nitric oxide bioavailability when going into exercise.

Proteins: Your Body’s Building Blocks

Proteins are less involved in our daily energy levels during activities or at rest, and are more involved in the recovery processes across your entire body. As members of a gym, we think in terms of muscle tissue, but realistically, protein and amino profiles from our diet are involved in building all cells from our own DNA structures. We need proteins to utilize our “genetic scaffolding” and, from that, adapt and build new tissues after they break.

Maintaining a consistent protein intake of around 0.8-1.1g per kilogram per day is a minimal maintenance guideline. That need could be higher based on the individual, their regular physical activity, and other lifestyle factors.

One consideration after exercise would be to consume protein and carbohydrates within a 45-minute window after exercise. For strength training, that would look like a 3:1 ratio of grams of protein to carbohydrates. This would aid in replenishment of glycogen (“sugar” in our muscles) after exercise and may mitigate loss of muscle mass after exercise.

How NIFS Can Help

If you’d like to learn more about your caloric needs at rest or with activity, please contact our fitness center. We offer RMR (resting metabolic rate) testing, as well as Vo2 Max testing. Both assessments may help you dial your diet to reach your goals.

Starting your fitness journey is always an exciting step forward, but it is essential to make sure you are listening to your body and prioritizing your recovery and self-care. Many people tend to neglect their bodies' needs and push themselves past their limits, which isn’t necessarily a bad thing. The importance of recovery and self-care play a crucial role in ensuring your long-term success in the gym, and one mistake can lead to a possible injury that can take away and/or limit that progress.

The Importance of Recovery

Recovery is one of the most important aspects of any fitness regimen. Giving yourself enough time to recover helps your body repair and strengthen itself. Without giving the proper recovery your body needs can lead to a higher risk of fatigue, decreased performance, and increased risk of injuries. Here are a few key components to ensuring you have an effective recovery period:

• Rest Days: Incorporating rest days is essential in allowing your body to heal and grow your muscles. You typically want to aim between 1-3 times a week depending on your fitness level and intensity for your workouts, so it may vary from person to person.
  
  
• Sleep Quality: Quality of sleep is a must for effective recovery. Anywhere between 7-9 hours a night is optimal to support muscle repair, hormone balance, and overall mental and physical health. Maintaining a consistent sleep routine will help manage your body's recovery each day.
  
  
• Hydration and Nutrition: Proper hydration and nutrition play a significant role in your body’s growth and recovery. Ensuring that you are drinking plenty of water during the day, and focusing on a balanced diet with protein, healthy fats, and complex carbohydrates will keep your body properly replenished and aid in muscle growth and repair.

Self-Care Practices

• Mobility and Stretching: Practicing stretching and focusing on mobility work regularly can help enhance flexibility, reduce muscle soreness, and prevent injuries. Incorporating dynamic stretching before workouts and static stretches after workouts helps maintain your muscle's elasticity and joint health. This can help with knee pain, lower back issues, and posture over time.
  
  
• Mindfulness: Mental wellness is just as important as physical wellness. Practicing mindfulness can help reduce stress, improve your focus, and enhance your overall well-being. Focus on relaxing the mind for a few minutes a day to help clear your head, such as deep-breathing exercises to calm the mind and body. This can be paired with your static stretches to help your mind and body at the same time.
  
  
• Active Recovery: On rest days, engaging in active recovery activities such as swimming, biking, yoga, or walking can help promote blood flow, reduce muscle soreness, and aid in muscle recovery without straining your body. Ensure that you are keeping a low intensity when engaging in these activities.

Prioritizing your recovery and self-care can play an important role in enhancing your performance, maintaining a balanced lifestyle, and helping prevent injuries. These practices will not happen overnight and will take dedication and time to achieve but will help you in the long run. Embrace, motivate, and stay consistent, and embark on your fitness journey prepared and ready to take on any challenge.

If you're unsure where to start or want to ensure you have the right balance between your fitness goals and recovery, or if you're simply looking to work with a professional, NIFS offers personal trainers who can help guide you every step of the way. Take the next steps with the support you need!

Over the past six to eights weeks, I have been creating summer workout manuals for the teams that I work with during the school year. These manuals are meant to bridge the strength and conditioning gap between the time they leave for summer break and when they return for the fall semester. There is much to be gained, or lost, through a summer of hard work (or lack thereof). Although summer break is a true “break” for most athletes academically, there never really is a true break for training.

Many of the teams I work with are spring sports. Their seasons begin a couple months after the turn of the year and may not finish until after school is out. They go from the playing field, track, course, or court, back home where family, friends, and summer jobs await. Being spring sports, their summer usually begins with a recovery period that occurs when their competitive season comes to a close. The components of this recovery process include mental, emotional, and physical aspects that need to be met in order to fully prepare for the next bout of training and the following season.

For the sports that I work with, the first portion of the training calendar for the post-season is called active rest. Active rest is an approximately two-week period where the athlete performs light physical activity at least two to three days per week. These physical activities should have nothing to do with the sport that they participate in. Think about it: after spending six to seven days per week over the past four months participating or thinking about their specific sport, the last thing many individuals want to do is continue to do just that. Although this is the sport that you may love, getting away from it for a short period of time can do wonders.

Taking a Break from Training

Active rest can mean a lot of things, and the best part is the fact that you basically have free reign over what you choose to do, as long as you are staying active. This gives you the opportunity to choose something totally unrelated to your sport and do it for the next few weeks.

I would recommend that the intensity of the activity you choose not climb above “moderate.” The low to moderate style will allow adequate blood flow to working muscles, which will help promote physical recovery of the muscles that were taxed so much during your competitive season. Another recommendation I would make would be to limit the amount of impact (foot strikes) you have during this period, especially if your sport requires a large amount of impact. This will allow your body to recover from the constant “ground and pound” that you might have during track, tennis, or softball season.

Active rest is also a good time to incorporate corrective exercises from the Functional Movement Screen (FMS) that your coach or trainer gave you. These exercises focus mainly on mobility and require very few pieces of equipment for the most part. Spending two to three weeks working on any muscular imbalances that may have developed during the season will give you a leg up when you begin your intense off-season training program in a month or so.

Active Rest Recommendations

Following are my top 5 recommendations for the rest period of your training:

• FMS corrective exercises
• Swimming
• Hiking
• Bike/elliptical/arc trainer/rower
• DO SOMETHING FUN!

Physical recovery is definitely important during this time, but recovery of your mental and emotional well-being may be just as or possibly more important. Let’s face it—any competitive season has a multitude of ups and downs, which creates an emotional rollercoaster that could send anyone through a loop. You have spent 48 out of the past 52 weeks preparing or playing your sport. You owe it to yourself to do something a little different and come back refreshed for the preparation for the next season.

If you have any questions about how to set up active rest for your post-season training, or need help constructing an off-season training program for your sport, contact me at asoller@nifs.org. To read more about setting up training programs for athletes, see my blog series that begins here.

With the Indianapolis 500 approaching, a lot of traditions and stories are being shared. As we head into the month of May and all of the events leading up to race day, the one that as a dietitian I am most intrigued about is, “Why does the winner drink milk?”

I love a glass of cold milk: cow’s milk, soy milk, chocolate milk, almond milk, cashew milk…it doesn’t matter to me. But after a hot and sweaty trip around the oval 200 times, I’m not sure that would be my drink of choice.

The History of the Indianapolis 500 Milk Legend

Here is some history on the interesting choice of beverage for the winner of “The Greatest Spectacle in Racing” year after year. The Indianapolis Motor Speedway writes this:

Three-time Indianapolis 500 winner Louis Meyer regularly drank buttermilk to refresh himself on a hot day and happened to drink some in Victory Lane as a matter of habit after winning the 1936 race. An executive with what was then the Milk Foundation was so elated when he saw the moment captured in a photograph in the sports section of his newspaper the following morning that he vowed to make sure it would be repeated in coming years. There was a period between 1947-55 when milk was apparently no longer offered, but the practice was revived in 1956 and has been a tradition ever since.

It is also interesting to note that the American Dairy Council pays a sponsorship of $10,000 to the winner of the race if they sip milk after their victory. Two drivers skipped the milk in recent years. In 1993 Emerson Fittipaldi opted for orange juice, and in 1981 Bobby Unser also refused. 

Milk for Workout Recovery

We have known for years that chocolate milk is the gold standard in recovery after strength training, so why not grab a glass of cold calcium-packed milk after a grueling workout? Even though it is seen as a strange tradition, it is the perfect recovery fuel after hours spent in a hot car.

The benefit of the chocolate (or any flavor) milk is the additional sugar to help replace what was just burned during the workout; however, even if it is not flavored, the carbohydrates in white milk are beneficial. Chocolate milk does have the perfect ratio of carbohydrate to protein, so if that is available it would be the best choice. Keep in mind that non-dairy milk such as almond, cashew, and hemp do not have the protein component that is key for recovery. 

The good news is that milk isn’t just for winners of the Indy 500. Anyone can benefit from this delicious beverage after a workout. Grab your favorite kind soon!

Building muscle is perhaps the most common goal (second to fat loss) of an exercise program. Many people eventually hit a plateau with exercise routines and muscle-gaining processes and find it increasingly difficult to continue putting on new muscle. Once the body becomes too familiar with certain exercises or a certain style of training, your results will be hindered.

However, you might in fact need to take a closer look at your training habits before you jump to the conclusion that you have hit a plateau. Take a look at my top 5 muscle-building mistakes, and how to power through the plateau and continue making gains.

1. Overtraining

Overtraining is a very real trap to which many people trying to gain muscle fall victim. In our society we often think that when trying to gain muscle, “more is better.” However, when it comes to training, more is often not better. Only the right amount of the right type of training will be beneficial to increasing muscle in the body.

The easiest way to explain this concept is to first point out that in order for muscles to grow in size (hypertrophy), they must be allowed to fully recover from micro tears experienced during an intense resistance-training workout. If we fall into the trap of thinking more is better, we often find ourselves either doing an absurd amount of sets and reps for each muscle group, or training the same muscle group multiple times a week, and not allowing proper recovery time. While I do applaud the effort in this technique, I have learned from personal experience that sometimes instead of training harder, we must train smarter.

2. Under-training

As opposed to mistake number 1, numerous people also often under-train when working out. Under-training happens when you walk into the gym and head over to the leg extension machine, perform a set of 12 reps at low-moderate intensity, and play with your phone for 2 or 3 minutes while resting, waiting on your next set. When trying to build muscle, the number of reps you complete does not mean anything if you are not bringing the correct intensity to those numbers. If you are on rep 12 and it feels like you are trying to lift a car, you are at the correct intensity for that exercise. If you get to rep 12 and you are already looking forward to your next set because you felt as though 12 reps was not enough, you might not be training with the proper intensity to build muscle. A good workout should come with challenges; therefore, you should almost be reaching failure on each set you do. If a person does not push themselves close to their limits, gaining new muscle and improving lifts will be rather difficult.

3. Avoiding the Hard Exercises

Most of us are guilty of this (including myself). We tend to avoid the hard exercises because they challenge our comfort level in the gym. However, since a majority of the “hard exercises” we tend to avoid happen to be compound exercises, we are actually doing ourselves a huge disservice. Compound exercises are extremely beneficial when trying to build muscle. They tend to use multiple muscle groups at the same time (even the ones we are not accustomed to working out individually). Therefore, compound exercises are great not only for working the major muscle groups in the body, but are also great for working the smaller muscle groups, which will result in improved strength levels overall that should transfer over to other lifts.

4. Failure to Build a Foundation

Before you can move to the “hard” or compound exercises, you must first build a solid foundation through muscular strength, muscular endurance, and proper movement patterns. These three components tie into one another very closely. If a person does not have a solid foundation with correct movement patterns, he or she will be performing compound exercises with improper lifting techniques, causing untargeted muscle groups to compensate. If the targeted muscle is not firing as effectively as it should be within the compound exercise, how can you expect a great deal of muscle growth?

Conversely, if a person has not improved their muscular endurance before attempting to improve their muscular strength, he or she might only be able to lift a certain amount of weight for only a short time (due to lack of muscular endurance), even if the person has learned proper movement technique. Lastly, if a person has not improved their muscular strength, it will be very difficult to continuously improve the weight needed to lift in order to create muscle hypertrophy (or size). So as you can see, building those three foundations first plays a huge role in long-term increase of muscle.

5. Nutrition

The last and arguably most common mistake seen when trying to build muscle is actually undernourishing the muscles themselves. Can you really expect your muscles to be able to grow when you are not giving them the proper amount of nutrients? That’s like expecting your car to survive a family road trip from Indiana to California without putting gas in it first. It simply won’t happen.

The mistake we usually make is thinking that as long as we are allowing our bodies to be in a “caloric surplus,” we will grow new muscle as long as we participate in a consistent resistance-training program. Unfortunately, not all foods are created with equal nutritional value, meaning there are foods we consume on a daily basis that are not giving us the proper amount of protein, carbohydrates, and healthy fats our muscles need in order to grow. Instead they fill us up with “empty calories” (no nutritional value) that include calories from sugar and saturated fat that provide little to no health benefits.

To make matters even worse, you actually intake more calories per gram when you consume fats compared to carbohydrates and proteins.

***

Many times people overlook these mistakes when trying to build muscle. However, if you begin to understand that all of these factors play a huge role in the efficiency of the muscle-building process, you will finally be able to get past the physical barriers you have unintentionally created for yourself.

We know it is encouraged by fitness professionals, and included at the end of group exercise classes, but I want to ask you, personally: how many times after a workout do you actually take the time to cool down?

Many of us tend to finish a hard workout and walk right to the showers or straight to our cars to hurry and get home to the next item on our to-do list. Some of us may not notice much of a difference whether or not we incorporate a cool-down, such as athletes or active adults. However, according to the American College of Sports Medicine, “for the general population, many apparently healthy adults may have heart disease or other diagnosed conditions,” making a cool-down a game-changer for not only everyday movement abilities, but safety.

Here are just a few reasons why you shouldn’t skip out on a few minutes of recovery.

1. Prevent Dizziness

If you have ever felt lightheaded immediately after a hard workout, it could very well be caused from blood pooling. Strenuous exercise causes the blood vessels in your legs to expand, bringing more blood into the legs and feet. After physical activity, your heart is beating faster than normal, and your core body temperature is higher. When you abruptly stop exercising without taking time to cool down, your heart rate slows immediately, which can cause blood to pool into the lower body, causing blood to return at a slower rate to your heart, and your brain. This in turn can cause you to experience dizziness or fainting.

Many accidents in fitness centers actually tend to occur in the locker room from members making a beeline straight to the locker room, steam room, or sauna after a tough workout, without taking adequate time for their body to calm down.

2. Flexibility Is at Its Best

When you finish a tough workout, as stated before, your core body temperature is higher. This means that your muscles are warm and ready for more static stretching. Dynamic stretching is recommended at the beginning of a workout, so static stretching (in other words, taking a deep breath and holding a stretch in a particular position for 15 to 30 seconds at a time) is the next step you can take in maintaining and increasing elasticity in the muscles. This lengthening of the muscles leads to better range of motion and, in turn, improved quality of life for daily activities.

3. Injury Prevention

Tagging onto flexibility, you can prevent yourself from acquiring common injuries with some of this mobility work. One of the most common injuries is in the lower back, which can sometimes be triggered by tight hip flexors and hamstrings. By simply adding some mobility work after you finish, you can not only increase your range of motion, but also increase your ability to catch yourself when you fall or have to react quickly to an unstable surface.

4. Restoration for Your Body

Whether it be simply slowing down to a light jog or walk after some light sprints, or by moving into a savasana pose at the end of a yoga class, a cool-down can have physiological benefits on the body in terms of finality. When we slow down, we feel a “sense of normality” come back into our extremities, and the body begins to restore itself back to a steady state. In other words, it just feels nice!

So whatever you decide to do at the end of your workout, I encourage you to take a moment to think twice for next time. Whether it be adding five minutes of walking to bring the heart rate down, or an extra five minutes to stretch while your muscles are warm, it’s important to note that there are no negative effects to the process. It can only help you in the long run!

There are so many things in life that can affect different aspects of the human body, and stress is one of the biggest! During a stressful time in life, the body can undergo several physiological changes that can be detrimental to your overall health. Though sometimes we cannot avoid certain stressors that fall into our path of life, there are some things that can be done to help you cope during those times.

What Stress Can Do to You

Let’s take a look first at how stress affects the body.

• Sleep: Stress disturbs sleep routines, typically making it hard to fall asleep as the mind wanders, tossing and turning, and constant interrupted rest.
• Upset stomach: Another effect is having a constant feeling of being queasy or nervous.
• Loss of appetite: Along with having an upset stomach, loss of appetite comes with either consistent or high levels of stress.
• Rash: Stress can cause hives, which are a type of skin rash. Be sure during stressful times to take care of your skin by washing and moisturizing.
• Change in eye pressure: When under high amounts of stress, the pressure of your eyes can change, causing something called ocular hypertension, which affects your vision.
• Increase in blood pressure: Whether it’s short-term or long-term stress, spikes in your blood pressure can be detrimental to your overall heart health.
• Increase in resting heart rate: The number of times your heart beats per minute can increase with stress levels and cause your heart to work harder than it normally would.
• Weight loss: Excessive weight loss can come with stress as your body loses its desire to eat.
• Chronic headaches: Anxiety and stress can increase the amount of headaches you get, as well as the intensity.
• Back pain: Each person holds stress in their body in different places, oftentimes residing in the back and neck muscles, making it painful to move.
• Sweating: Stress triggers sweat glands to become more active, causing you to break out in cold sweats (like you are nervous).
• Tremors: Sudden twitches or tremors can be caused by stress, resulting in the contraction or continuous spasm of the muscles.
• Bowel issues: One way or the other, bowel issues can happen when under stress.

Overcoming Stress

Now, I know that sometimes stress is out of our control, but when those times come there is something we can do about it. Exercise is one of the proven ways to keep stress levels low. If you are feeling stressed out, try coming to the gym or fitness center to workout, run or walk, do yoga, or whatever you like to do to help you decompress.
