Preventing Running Injuries

Incorporating running into your daily exercise routine is one of the easiest ways to stay fit, however, it is also known to be the easiest way of developing an injury. Aches and pains caused by running aren’t just common in beginners but also expert level runners as well. Are you a runner and have been experiencing pain during or afterward? Free Body Physical Therapy offers our Knee Specialist Chicago to help treat your running injuries no matter the severity and also help you prevent new running injuries in the future. 

Common Running Injuries

Running injuries usually occur when you push yourself too hard, especially if you are new to running. Additionally, the way your body moves during these actions impacts your overall health as well. Common running injuries and pains may include but are not limited to:

How to Prevent These Injuries From Occurring

If you are a seasoned runner or even just starting, there are many methods you can take into consideration when running to help prevent future injuries from occurring. It is important to always put your health and body first, and you should always be your main priority. Here are some helpful tips from our Knee Specialist Chicago and ways to prevent future running injuries from occurring that include but are not limited to: 

  1. Wear proper footwear- When running your shoes should fit properly and made for running specifically. It is also important to replace your sneakers when they become worn out, losing their support over time.
  2. Warm-up properly- Walking or jogging first is known to loosen up your muscles and joints before increasing your effort.
  3. Stretching- Dynamic stretching before your run and static stretching after your run.
  4. Avoid overtraining- As much running daily can seem like the best way to stay as fit as possible, your body needs rest days which are equally as important.
  5. Cross-train- Running is not used by itself to stay fit and keep a healthy lifestyle. You need to be in good shape overall to run without developing injuries
  6. Change up your running route- Running the same route daily can begin to become monotonous and boring. To keep your running routine fun and interesting, changing up where you run can help to make the experience more enjoyable.

The Benefits of Hiking

We all know that regular cardiovascular exercise is good for us, but many of us cannot seem to make it to the gym. How about ditching the treadmill and spending time in nature? Hiking has been shown not only to be great cardio but can also benefit your mental health. Our Knee Specialist Chicago at Free Body Physical Therapy recommends hiking as a great form of exercise.  

Physical Health Benefits of Hiking

Hiking carries all of the benefits of cardiovascular exercises such as improving your blood pressure and blood sugar levels, lowering the risk of developing heart disease, and helping to control your weight. Hiking can also help keep up your bone density because it is a weight-bearing exercise. 

Unlike standard cardio such as walking on a treadmill, hiking covers some uneven terrain, helping to improve your balance and strengthen your lower body and core muscles. Many doctors and health professionals, such as our Knee Specialist Chicago at Free Body Physical Therapy have been recommending hiking in recent years because of the wonderful benefits it has for the body and mind.  

Mental Health Benefits of Hiking

Exercise has the potential to increase mental health by reducing anxiety and depression. Spending time outdoors in nature can also do wonderful things for your mental health. Going for a hike gives you time to unplug from technology, as well as taking your mind off of the stresses of daily life. 

Hiking is an activity that combines the benefits of exercise with the benefits of nature to help boost your mood and reduce the negative effects on your mental health, which is why our Knee Specialist Chicago sees hiking as an amazing form of exercise.  

Hiking Safety Tips

Before hitting the trails, make sure to keep these safety measures in mind! Start off your hiking journey slowly. You may be eager to hit the long and tough trails, but as a beginner, it is important to keep your ability in mind. You can always work up to a tougher hiking route, but treating an injury can keep you from hiking all together! If an injury does occur, Free Body PT’s Knee Specialist Chicago can help you get back to hiking in no time. 

Suggestions From Our Knee Specialist Chicago

It can be dangerous to hike alone, especially at the beginning. You may be on an unfamiliar or secluded trail, and it is best not to risk being stranded. Having a friend or family member hike with you can help you feel safer, and give you some company on your hike! Come prepared for your hike. You should familiarize yourself with the route you will be taking, as well as packing your bag correctly. Wear sunscreen and bring lots of water to make sure you stay hydrated!
