Abdominal pain in long distance runners: case report and analysis of the literature.

Abdominal pain is a common complaint among participants in endurance sports. It may be severe, recurrent, and resistant to treatment. There is no direct evidence of the cause of this phenomenon. This report is of a long distance runner who had severe pain in the upper right abdominal quadrant during strenuous exertion. The symptom had been present for several years and did not respond to conservative treatment. Laparoscopy showed congenital supernumerary ligaments binding the gallbladder to the abdominal wall. The complaint resolved after cholecystectomy and resection of adhesions. There was evidence of chronic cholecystitis on histopathological examination. Two years after the operation, he remains free of symptoms. The differential diagnosis of abdominal pain in athletes is discussed.

Effects of exercise on cancer-related fatigue.

Cancer patients frequently suffer from fatigue and loss of physical performance. Several biologic, psychologic, and social factors have been suggested as explanations for the origins of fatigue in this context. In most cases, fatigue has a multifactorial genesis. However, recent studies suggest that fatigue may originate from alterations in the muscular energetic systems caused by cancer and its treatment. Furthermore, there is growing evidence that physical exercise programs help prevent the manifestation and reduce the intensity of cancer-related fatigue. In this article, actual evidence of the relationship between fatigue and impairment of physical performance in cancer patients and suggestions for new directions for research are discussed.

Effects of physical activity on the fatigue and psychologic status of cancer patients during chemotherapy.

BACKGROUND: Fatigue is a common and often severe problem in cancer patients undergoing chemotherapy. The authors postulated that physical activity training can reduce the intensity of fatigue in this group of patients. METHODS: A group of cancer patients receiving high dose chemotherapy followed by autologous peripheral blood stem cell transplantation (training group; n = 27) followed an exercise program during hospitalization. The program was comprised of biking on an ergometer in the supine position following an interval training pattern for 30 minutes daily. Patients in the control group (n = 32) did not train. Psychologic distress was assessed at hospital admission and discharge with the Profile of Mood States and Symptom Check List 90. RESULTS: By the time of hospital discharge, fatigue and somatic complaints had increased significantly in the control group (P for both < 0.01) but not in the training group. Furthermore, by the time of hospital discharge, the training group had a significant improvement in several scores of psychologic distress (obsessive-compulsive traits, fear, interpersonal sensitivity, and phobic anxiety) (P value for all scores < 0.05); this outcome was not observed in the control group. CONCLUSIONS: The current study found that aerobic exercise can reduce fatigue and improve psychologic distress in cancer patients undergoing chemotherapy.

Aerobic exercise in the rehabilitation of cancer patients after high dose chemotherapy and autologous peripheral stem cell transplantation.

BACKGROUND: Fatigue and loss of physical performance are frequent problems of cancer patients. In a pilot study, the authors evaluated the feasibility and effects of aerobic training in the rehabilitation of cancer patients after completing high dose chemotherapy. METHODS: Sixteen patients participated in a specially designed rehabilitation program for 6 weeks. The patients entered the program, which consisted of walking on a treadmill, shortly after completing treatment. Sixteen patients who did not train served as controls. Physical performance (maximum speed on the treadmill test), cardiac function, and hemoglobin concentration were compared at the time of discharge from the hospital and 7 weeks later. At the second examination, fatigue and limitations in daily activities due to impaired endurance were assessed during personal interviews. RESULTS: At the time of discharge from the hospital, maximum physical performance (training group: 6.2 +/- 1.1 km/hour; controls: 6.2 +/- 1.3 km/hour) and hemoglobin concentration (training group: 10.1 +/- 1.4 g/dL; controls: 10.1 +/- 1.2 g/dL) were similar for both groups. After 7 weeks, improvement in maximum physical performance (training group: 8.3 +/- 1.6 km/hour; controls 7.5 +/- 1.3 km/hour) and hemoglobin concentration (training group: 13 +/- 1 g/dL controls: 12 +/- 1.4 g/dL) were significantly higher for the training group (P < 0.05). By the second examination, no patient in the training group but 4 controls (25%) reported fatigue and limitations in daily activities due to low physical performance. CONCLUSIONS: Aerobic exercise improves the physical performance of cancer patients recovering from high dose chemotherapy. To reduce fatigue, this group of patients should be counseled to increase physical activity rather than rest after treatment.
