The bottom line with regard to sports participation is preserving you and your baby's health. You must consider risk of falls, not only because this can affect the pregnancy, but also because x-rays, medications, and surgeries needed to evaluate and treat injuries can be harmful to the pregnancy. Repeated forceful impact can disrupt the placenta and put the pregnancy at serious risk. Environmental conditions such as high altitude and severe temperatures can interfere with the flow of oxygen and blood to supply the baby. These risks are relative to skill level and what your body is used tofor example, skiing at a high altitude is not recommended for most, but for a woman who lives at a high altitude and skis without falling, it can be done with caution due to other falling into her. General recommendations for sports are avoiding risks of falls and trauma, especially abdominal injury due to contact and impact. Falls should especially be avoided because impact can cause placental abruption, and orthopedic care of injuries such as x-rays or surgery can be risky to the fetus.

Environment is very important to the health of your pregnancy. Vacationing or exercising at altitudes above 8,500 feet is not recommended due to lower oxygen content (unless you already live there, in which case your blood has adapted to this). If you are planning a ski or hiking trip, stick to the lower-altitude resorts. You can also be more prone to altitude sickness than when you are not pregnant, so beware of symptoms of light-headedness, headache, nausea, insomnia, poor appetite, or fatigue, and drink even more fluids than usual. As with any change in climate, take a few days to let your body adjust to the new altitude before beginning physical activity in the new environment. Temperature, as previously discussed, is a major consideration. Avoid exercising in temperatures above 80 degrees Fahrenheit.
Specific Sport Guidelines for Exercising During Pregnancy Most sports can be continued with modifications. If you have any questions check with your doctor before participating. For all standing and weight-bearing exercises, make sure your shoes fit comfortably and are not too tight; it is common for feet to become swollen, so purchase shoes to accommodate. Also, make sure you have good cushioning to accommodate your added weight. Your exercise shoes should be replaced at least every three months. The following are generally recommended activity modifications:
AerobicsAvoid crowded, overheated rooms, and avoid advanced step or kickboxing classes to prevent falls or injury. After the second trimester, avoid bouncing movements and more than five minutes of lying on your back; do not do exercises lying on your stomach. Be careful that stretching is not done quickly or forcefully. Low-impact and water aerobics are less likely to cause injuries.
CyclingChanges in body weight, posture, and center of gravity can affect balance. A stationary bicycle is usually a safer choice. Elite-level cyclists might want to change from a racing bike to a mountain bike for more shock absorption and an upright position for increased comfort and visibility.
Racket sportsAs pregnancy progresses, decrease the aggressiveness of play to avoid falls and ankle sprains due to changes in center of gravity and coordination.
Running / joggingIt is not recommended that you begin a running program during pregnancy, but if you have been running prior to your pregnancy, jogging can continue at shorter distances as long as you are physically comfortable, drink plenty of fluids, and stay cool.
Skiing/snowboardingDownhill activities should only be done if you are very experienced and do not fall. Cross-country skiing is much safer due to its much lower risk of falls. Special attention must be paid to fluid intake, as the cold weather makes you feel that you are not sweating, but you are. Follow the same fluid recommendations for any aerobic activity. Unless you already live at high altitude, you should not go above 3,000 feet. Most doctors prohibit skiing and snowboarding at all stages of pregnancy.
SwimmingSwimming is one of the favorite pregnancy exercises, especially in the third trimester, when floating takes pressure off your spine and joints. Do not dive or jump in the water, and extremes of water temperature need to be avoided. Swimming is not advisable if there is any vaginal fluid leak.
Weight trainingThe goal of weight training in pregnancy is to maintain, not gain, strength. Routines should be modified with lighter weights and fewer repetitions with no straining. Proper breathing technique is important to avoid breath holding, which increases blood pressure, decreasing blood flow to the baby. Positions should be modified to avoid lying flat on your back in the third trimester. Avoid lifting weights so heavy that you would normally require a spotter.
Tips for Safe Jogging While Pregnant
Jog in the coolest part of the day.
Jog in air-conditioning if the temperature is above 80 degrees or humidity is above 90 percent.
Make sure you are always comfortable, not overexerting yourself, but feeling well.
Consider wearing a maternity support after the 5th month (see figure 15-1B).
Wear well-cushioned athletic shoes that are wide enough and fit well.
Wear an athletic bra with extra support.
Wear layered clothes that can be removed as you warm up.
Take water with you.
Stay within a 15-minute radius of home.
Consider jogging on grass to lessen impact.
Take a cell phone with you in case of emergency.
Be flexible with your workout goal and ready to decrease distance if you do not feel well.
Avoid strenuous hills.
Stick to populated areas.
Walk if you feel uncomfortable.
Wear a heart rate monitor and do not let your rate go over 150; 140 if you are over 40.
Spend the last 10 minutes walking to cool down.
Tips for Safe Swimming While Pregnant
Avoid crowded pools in which you might be kicked.
Avoid pools that feel too warm.
Keep a water bottle poolside and finish it by the time you are done.
Skip your "no breathers" until after pregnancy.
Stop and rest if you are short of breath.
Wear swim fins if you are having trouble moving through the water.
Avoid flip turns if they feel uncomfortable or lead to dizziness.
Tips for Safe Exercise Class Participation While Pregnant
Avoid crowded classes where you might bump into your neighbor.
Leave if the room becomes too hot.
Have water available, and drink every 10 minutes.
Work at your own pace, do not push yourself past what makes you comfortable.
Avoid advanced step or kickboxing classes due to risk of falls.
Do not participate in any repetitive bouncy or quick-stretching motions.
In the third trimester, do not lie on your stomach.
In the third trimester, lie on your side instead of your back whenever possible.
Use your own towel and wash your hands to prevent illness.
To date, no doctors or researchers can draw a specific line on what activities can and cannot be done during pregnancy. Everyone is different as to what they and their pregnancy can tolerate. However, to be sure, use the safe tips above and remember the following points: Make sure you are slowly gaining weight after the first trimester, about one pound per week; maintain your exercise activity at a lower level than you were doing before; make sure you are comfortable at all times during exercise. Remember that pregnancy changes actually improve your fitness level on its own. Your lower level of exercise will leave you extremely fit after pregnancy. Four to six weeks after a normal preg nancy and delivery, you should feel able to gradually return to your prior exercise routine and be back to feeling fit in two to three months.
