Análise da atividade e fadiga muscular de extensores da coluna vertebral e abdominais em ciclistas e sua relação com a dor lombar baixa

Abstract

This study on cycling and its implications on the spinal column and abdomen resulted in two scientific articles that are shown below. The objective in Article 1 was to analyze the activation and abdominal and back muscle fatigue by surface electromyography (EMG) and its relation to back pain and abdominal pain in cyclists modalities Mountain Bike (MB) and road (RD) with subjects without participation in cycling (CT). The total of 39 subjects participated in the study, 13 in each group, and conducted the questionnaire and the electromyographic evaluation protocol for activation and muscle fatigue against gravity for 30 seconds. We conclude that MB has increased abdominal and lumbar activation, fatigue in RD appears faster than in CT and MB. Low back pain was higher in CT, and abdominal pain increased in all groups. Already in Article 2, the objective was to analyze the activation and abdominal and back muscle fatigue using electromyography (EMG) and its relationship with the training intensity in cyclists modalities Mountain Bike (MB) and road (RD), along with subject not cyclists (CT) of different age groups. The total of 78 subjects participated in the study, 13 in each group, and conducted the questionnaire and the EMG evaluation protocol for activation and muscle fatigue against gravity for 30 seconds. It was concluded that muscle fatigue cyclists tends to increase with age, even if the regular training intensity has increased in the group of cyclists 30-49 years.
