Intervention(s)

Participated in this study 31 teachers: 16 in Resistance Training Group and 15 teachers in the Control Group. The muscle endurance training consisted of two sets of 15 repetitions of knees flexion and extension, five seconds in concentric and five seconds eccentric phases, with range of one minute between sets, twice a week, during seven weeks. The exercises were carried out with maximum load 50% at 1st-4th weeks and with the maximum load of 60 at 5th-7th weeks. The groups were assessed before and after seven weeks. The CG participated at evaluations but not at training.

Primary Outcome(s)

Peak of torque and rate of force development increase, measured by load cell. Musculoskeletal disorders decrease, evaluated by The Nordic Questionary.

Secondary Outcome(s)

Strength increase, evaluated by 10 Repetion Maximum test (10RM).
