PT management commonly includes prescription of or assistance with specific exercises, manual therapy, and manipulation, mechanical devices such as traction, education, electrophysical modalities which include heat, cold, electricity, sound waves, radiation, assistive devices, prostheses, orthoses, and other interventions.
- Weight Management and Obesity: Combined with a healthy diet, aerobic exercise helps you lose weight and keep it off.
- Increase your stamina, fitness and strength You may feel tired when you first start regular aerobic exercise. But over the long term, you'll enjoy increased stamina and reduced fatigue. You can also gain increased heart and lung fitness and bone and muscle strength over time.
- Ward off viral illnesses Aerobic exercise activates your immune system in a good way. This may leave you less susceptible to minor viral illnesses, such as colds and flu.
- Reduce your health risks Aerobic exercise reduces the risk of many conditions, including obesity, heart disease, high blood pressure, type 2 diabetes, metabolic syndrome, stroke and certain types of cancer. Weight-bearing aerobic exercises, such as walking, help decrease the risk of osteoporosis.
- Manage chronic conditions Aerobic exercise may help lower blood pressure and control blood sugar. It can reduce pain and improve function in people with arthritis. It can also improve the quality of life and fitness in people who've had cancer. If you have coronary artery disease, aerobic exercise may help you manage your condition.
- Strengthen your heart A stronger heart doesn't need to beat as fast. A stronger heart also pumps blood more efficiently, which improves blood flow to all parts of your body.
- Improved Cardiovascular Health Aerobic exercise boosts your high-density lipoprotein (HDL), the "good," cholesterol, and lowers your low-density lipoprotein (LDL), the "bad," cholesterol. This may result in less buildup of plaques in your arteries.
- Boost your mood Aerobic exercise may ease the gloominess of depression, reduce the tension associated with anxiety and promote relaxation. It can also improve your sleep.
- Stay active and independent as you age Aerobic exercise keeps your muscles strong, which can help you maintain mobility as you get older. Exercise can also lower the risk of falls and injuries from falls in older adults. And it can improve your quality of life. Aerobic exercise also keeps your mind sharp. Regular physical activity may help protect memory, reasoning, judgment and thinking skills (cognitive function) in older adults. It may also improve cognitive function in children and young adults. It can even help prevent the onset of dementia and improve cognition in people with dementia.
- Increased Longevity Studies show that people who participate in regular aerobic exercise live longer than those who don't exercise regularly. They may also have a lower risk of dying of all causes, such as heart disease and certain cancers.
Heart rate variability is literally the variance in time between the beats of your heart. So, if your heart rate is 60 beats per minute, it’s not actually beating once every second. Within that minute there may be 0.9 seconds between two beats, for example, and 1.15 seconds between two others. The greater this variability is, the more “ready” your body is to execute at a high level. These periods of time between successive heart beats are known as RR intervals (named for the heartbeat’s R-phase, the spikes you see on an EKG), measured in milliseconds.
Although HRV manifests as a function of your heart rate, it actually originates from your nervous system. Your autonomic nervous system, which controls the involuntary aspects of your physiology, has two branches, parasympathetic (deactivating) and sympathetic (activating).
The parasympathetic branch (often referred to as “rest and digest”) handles inputs from internal organs, like digestion or your fingernails and hair growing. It causes a decrease in heart rate.
The sympathetic branch (often called “fight or flight”) reflects responses to things like stress and exercise, and increases your heart rate.
Heart rate variability comes from these two competing branches simultaneously sending signals to your heart. If your nervous system is balanced, your heart is constantly being told to beat slower by your parasympathetic system, and beat faster by your sympathetic system. This causes a fluctuation in your heart rate: HRV.
When you have high heart rate variability, it means that your body is responsive to both sets of inputs (parasympathetic and sympathetic). This is a sign that your nervous system is balanced, and that your body is very capable of adapting to its environment and performing at its best.
However, if you’re not doing something active, low HRV indicates your body is working hard for some other reason (maybe you’re fatigued, dehydrated, stressed, or sick and need to recover) which leaves fewer resources available to dedicate towards exercising, competing, giving a presentation at work, etc.
To look at it another way, the less one branch is dominating the other, the more room there is for the sympathetic (activating) branch to be able to come in and dominate, which is why high HRV suggests you’re fit and ready to go.
A VO2 max test is a cardiovascular exercise test performed using a piece of cardio equipment, while connected to a machine capable of analyzing your ratio of expired oxygen to carbon dioxide emission. Your test provides data on how much oxygen you use as you exercise and determines the maximal oxygen you can consume during exercise. This is a gold-standard measurement of endurance.
RMR - Resting Metabolic Rate Assessment:
An RMR test directly measures the concentration of oxygen breathed out by each patient. The patient merely breathes through a simple mouthpiece as all the exhaled air is collected and analyzed through a respiratory machine . Because there is a direct correlation between oxygen consumed and calories burned (4.813 calories for every milliliter of oxygen consumed), an accurate measurement of oxygen consumption is an effective measurement of calorie consumption.
A resting metabolic rate (RMR) test is a noninvasive, highly accurate way of determining daily calories needed to maintain your current body mass. It can be challenging for individuals to know exactly how many calories are necessary to support their goals, whether it be to lose weight or gain weight. Measuring RMR is a beneficial first step to determine how many calories you need to support your body's basic energy requirements. RMR data will be used to provide you with healthy nutritional guidelines to support your goals.
