Health & Exercise Forum

Recently, two patients asked me when I thought it would be safe for them to return to their exercise programs after abdominal surgery. She stated that she was not sure how to properly and safely implement or return to her program.

This column will attempt to ensure a safe return to activity and exercise following general surgery such as gall bladder, appendix, hernia, etc. The post-operative patient has many questions: When is it safe to begin an exercise program? How do I begin? What is the best exercise? Which exercises are best? How do I know if the activity is too intense or not intense enough? Are there safe guidelines?

• Medical Clearance

Before you begin, discuss your intention to exercise with your surgeon and  primary care physician. Get medical clearance to make sure you can exercise safely. With the exception of short daily walks, don’t be disappointed if your surgeon requires you to wait at least until your 6 week post-op check-up to begin exercise.

• Time for a Standard Work-out

While a 60 minute workout would be the long term goal, begin slowly at 15-20-30 minutes and add a few minutes each week. Make time to warm up and cool down.

Warm-up                                 5-10 minutes

Strength Training                    10-15-20 minutes

Aerobic                                   10-15-20 minutes

Cool down                              5-10 minutes

• Exercise Routine

• If the individual does not exercise regularly, start slowly and then increase activity level
• Importance of exercising in comfortable temperatures
  • Example: in the summer if exercising outside --- recommendation: early morning or late evening NOT during the middle of the day in the summer heat
  • Hydration before, during, and after exercise is important
  • Cellular Phone – for emergencies - take to hotel gym – especially if unattended

• Warm Up
  1. 5-10 minutes
  • Ways to warm up:
    1. Walking on a treadmill / around gym area
    1. Bike
    1. Stretching – active and gentle

• Strength Training – begin with light weights and increase repetitions
  1. 20 minutes
  1. Can begin with one set of 8 to 12 reps
  1. 2-3 times a week (do not exercise the same muscles 2 days in a row)
  • Exercises (Perform 8-10 different exercises that train all major muscle groups)
    1. Shoulders – Bent over row with weights  
    1. Back – Seated rows with bands or bent over with weights
    1. Chest – Chest press with weights or Push-ups
    1. Biceps – Biceps curl with weights
    1. Triceps – Triceps extensions with weights or Push-ups
    1. Abdominals – pelvic tilts or core exercises on ball  
    1. Gluteals – Leg Press, 30 degree Wall Slides
    1. Quadriceps – Knee extensions with ankle weights, Lunges, Squats
    1. Hamstrings -  Hamstring Curl 
    1. Calves – Calf raises

• Aerobic
  1. 20 minutes
  • Exercise
    1. Treadmill / walking outside
    1. Elliptical
    1. Bike (recumbent bike is recommended)
    1. Stepper
    1. Stairmaster

• Cool Down
  • 5-10 minutes
    1. Walking on a treadmill / around gym area
    1. Bike
    1. Stretching

How to Monitor Your Exercise Program:

• Target Heart Rate

First, determine your resting heart rate by taking your HR (pulse) using your index finger on the thumb side of your wrist for 30 seconds and multiply it by two. 80 beats per minute is considered a normal HR but it varies. This is a good baseline to use as a goal to return to upon completion of your workout. For example, your HR may increase to 150 during exercise, but you want to return to your pre exercise HR (80) within 3-5 minutes after you complete the workout.

For those who are healthy, calculating your target heart rate (HR) is an easy and useful tool to monitor exercise intensity.

220 – Your Age = Maximum Heart Rate

EXAMPLE for a 45 year old: 220 – 45 = 175 beats per minute should not be exceeded during exercise.

• Metabolic Equivalent (MET) Intensity for Exercise - Energy Cost of Physical Exercise.

            For those concerned about calories expended during exercise.

NOTE: Keep the level at a light/moderate level for the first four to six weeks and advance to the moderate/heavy at week six. The Very Heavy Level may not be appropriate for 12 weeks post op is for those who have a reasonable fitness level and exercise 4-5 days per week.

Example of Data Found on Fitness Equipment

Remember, this is only accurate if you program your correct height, weight and age.

Level                          kCal/min                    MET

Light                              2 - 4.9                     1.6 – 3.9

Moderate                        5 - 7.4                     4 – 5.9

Heavy                          7.5 - 9.9                     6 - 7.9

Very Heavy                  10 - 12.4                   8 – 9.9

• Cardiac Patient on Beta Blockers

Always secure physician approval before engaging in an exercise program.
If the patient is on beta blockers (Atenolol, Bisoprolol, etc), it is important to use the Borg Rating of Perceived Exertion Scale (RPE) scale to determine safe exercise stress since exercise will not increase HR as expected:

• Borg (RPE) Scale = indicates exercise intensity

0 - Nothing at all
1 - Very light
2 - Light
3 - Moderate
4 - Somewhat intense
5 - Intense (heavy)
6
7 - Very intense
8
9 - Very, very intense
10 - Maximum Intensity

NOTE: Keep the RPE at 2-3 the first 6 weeks post op and advance to level 3-4 at 8-12 weeks post op. Levels 5-6-7 are for those with a reasonable fitness level and exercise 4-5 days per week. The advanced levels should not be attained until 2-3 months of exercise and 3-4 months post op.
