However, it can also lead to decreased skeletal muscle mass and strength, increasing the risk of sarcopenia after surgery. This randomized clinical trial studied the effects of a 16-week exercise program on sarcopenia in bariatric surgery patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Thirty-seven surgery candidates participated in the EXPOBAR (EXercise POst BARiatric) program and were randomized into experimental or control groups. The intervention lasted 16\u00a0weeks, starting 1\u00a0month after surgery, and included a circuit training with aerobic and resistance exercise intervention. The outcomes included physical fitness parameters (anthropometry, body composition, and physical performance) and were assessed at four time points. All participants underwent gastric bypass surgery (RYGB).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The EXPOBAR trial revealed significant and meaningful effects of the exercise intervention on anthropometric indices, such as weight (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.039) and waist circumference (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.010).

The exercise program in this study effectively reversed the surgery-induced loss in function and strength, reducing the number of patients at risk of sarcopenia. Physical and functional capacity are crucial noninvasive indicators for diagnosing muscle quality and sarcopenia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Long-term management of sarcopenia and sarcopenic obesity in bariatric surgery patients requires frequent monitoring of body composition and muscle function.
