Changes in Pain and Muscle Architecture in Colon Cancer Survivors After a Lumbopelvic Exercise Program: A Secondary Analysis of a Randomized Controlled Trial.

OBJECTIVE: To investigate the efficacy of an eight-week lumbopelvic stabilization program (CO-CUIDATE) for colon cancer survivors. DESIGN: A secondary analysis of a randomized controlled clinical trial. SETTINGS: A blinded, trained researcher performed the end point assessments for pain (Pressure Pain Threshold and Brief Pain Inventory) and muscle architecture (ultrasound imaging measurements). SUBJECTS: Forty-six colon cancer survivors who were assigned to the CO-CUIDATE group or usual care group. METHODS: The CO-CUIDATE program was conducted for eight weeks. A trained researcher who was blinded to patient group performed the assessments. The tests were carried out with multiple observations. Intention-to-treat analyses were performed. RESULTS: The program had an adherence rate of 88.36% and two dropouts (10.5%). The participants reported some minor side effects during the first exercise sessions. The analysis revealed significant differences in the group x time interactions for the lumbar side (dominant: F = 3.1, P < 0.001; nondominant: F = 3.0, P = 0.01) and the infra-umbilical dominant side (F = 1.2, P = 0.04) after the program and at the six-month follow-up and for the internal oblique thickness (F = 5.1, P = 0.030) after the program. The experimental group experienced a greater improvement in all values after the program compared with the control group. There were no significant changes in the other pressure pain threshold points, pain severity, interference of pain, or the remaining ultrasound imaging measurements. CONCLUSION: The CO-CUIDATE program is effective for improving the musculoskeletal conditions related to the lumbopelvic area in colon cancer survivors, specifically in relation to pain and the internal oblique thickness.

Efectos del entrenamiento pliométrico sobre la resistencia cardiorrespiratoria de niños y adolescentes con síndrome de Down / Effects of a circuit training including plyometric jumps on cardiorespiratory fitness of children and adolescents with Down syndrome

Objetivo: Determinar los efectos de 21 semanas de entrenamiento en circuito, incluyendo saltos pliométricos sobre la resistencia cardiorrespiratoria de jóvenes con síndrome de Down (SD). Método: Veintisiete jóvenes con SD de entre 10 y 19 años participaron en este estudio. Los participantes se dividieron en dos grupos: ejercicio (EJE; n= 14) y control (CON; n=13). Antes y después de la realización del programa de entrenamiento se midieron los siguientes parámetros: tiempo de trabajo, valores máximos de consumo de oxígeno, cociente respiratorio, frecuencia cardíaca y ventilación minuto de los participantes mediante una prueba de esfuerzo progresiva en tapiz rodante. Resultados: Los participantes del grupo EJE aumentaron todos los parámetros cardiovasculares en comparación con su valor basal, después del entrenamiento (todos p< 0,05). Además, a pesar de tener unos valores similares antes del entrenamiento, el grupo EJE mostró valores más elevados que el grupo CON después del entrenamiento (todos p<0,05). Conclusión: Se puede concluir que los jóvenes con síndrome de Down pueden conseguir mejoras en diversos parámetros cardiorrespiratorios tras la ejecución de 21 semanas de entrenamiento con ejercicios pliométricos (AU)

Aim: To ascertain the effects of 21 weeks of circuit training, including plyometric jumps, on cardiorespiratory fitness of youths with Down’s syndrome (DS). Methods: Twenty-seven children and adolescent aged 10 to 19 years with DS participated in this study and were divided in two groups: exercise (EXE, n=14) and control (CON, n=13). Work time, peak values of oxygen consumption, respiratory exchange ratio, heart rate and minute ventilation of the participants were measured pre- and post-training with a graded exercise treadmill test. Results: EXE group increased all their cardiorespiratory parameters compared to baseline after 21 weeks of training (all P<.05). Additionally, and despite having similar pre-training values, the EXE group showed higher values than the CON group in all cardiorespiratory parameters after training (all P<.05). Conclusion: It may be concluded that youths with Down syndrome can achieve improvements in several cardiorespiratory parameters when performing 21 weeks of training including plyometric exercises (AU)
