Weight loss plus aerobic and resistance exercise could be the best for obese people

Aerobic exercise is also called cardio exercise. It requires heart to pump oxygenated blood and deliver to working muscles.

Usually, aerobic exercise increases heart rate and breathing rate during the training session.

Besides aerobic exercise, another popular exercise is resistance exercise. This exercise forces one’s skeletal muscles to contract.

Weight lifting is a typical resistance exercise. This is because it can cause contractions. These contractions can lead to improved muscle mass, endurance, and strength.

The new study

In a recent study, researchers find that aerobic and resistance exercise can help reduce frailty in obese people.

The researchers are from Baylor College of Medicine. They publish the findings in New England Journal of Medicine.

Previous studies showed that obesity causes frailty in older adults. However, weight loss might increase muscle loss and bone loss and people age.

Thus, it is important to reduce frailty while maintain the muscle and bone quality in obese people.

The team tested 160 obese older adults. They tried to find which exercise could help preserve muscle and bone mass, reduce frailty, and lose weight.

Participants took part in a weight-management program plus one of three exercise programs.

The exercise programs included aerobic training, resistance training, or combined aerobic and resistance training.

The researchers tested the change in Physical Performance Test score in 6 months. Higher scores indicate better performance.

They also tested changes in frailty measures, body composition, bone mineral density, and physical functions.

The results

They found that the Physical Performance Test score increased more in the combination group than in the aerobic and resistance groups.

In addition, the scores increased more in all exercise groups than in the control group (no weight loss or exercise).

Peak oxygen consumption increased more in the combination and aerobic groups than in the resistance group.

Additionally, strength increased more in the combination and resistance than in the aerobic group.

Body weight decreased by 9% in all exercise groups but did not change significantly in the control group.

Lean mass decreased less in the combination and resistance groups than in the aerobic group, as did bone mineral density at the total hip.

Finally, exercise-related adverse events included musculoskeletal injuries.

The authors suggest that weight loss plus combined aerobic and resistance exercise is the most effective for obese older adults. These programs can help improve obese people’s body functions.
