Resistance Exercise to Improve Fatigue in Workplace (REW) (REW)

April 16, 2019 updated by: Rosimeire Simprini Padula

Effectiveness of a Resistance Training Program in the Workplace to Muscle Fatigue Control in Industrial Workers: Cluster Randomized Controlled Trial.

Studies show that exercise resistance in workplace can reduce the symptoms of induced labor, however, the effectiveness of such programs depends on the characteristics of the training fatigue. Thus, it is expected that this study the intervention group with training heavy using progressive resistance exercise protocol will be better in reducing fatigue when compare with light training group.

Detailed Description

Background: This study is randomized clinical trial with double-blinded. The aim is evaluate the effectiveness the training heavy with resistance exercise program in the muscle fatigue control. Methods: This is a randomized controlled trial by cluster, in which workers who participate in the intervention group will perform resistance exercise protocols; and workers in the comparative group held only stretching exercises and light resistance training with elastic bands. Expected results: strong evidence that fatigue reducing after ten weeks in workers and improve in others outcomes. Not found in literature studies in occupational evaluating this aspect of training.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Compensatory Workplace Exercise (CWE)
Comparative Group will receive a light training protocol including warming up, stretching and resisted exercise using elastic bands.
Other: Compensatory Workplace Exercise (CWE) - Comparative Group
The comparative group will receive warming up and stretching and light resisted exercise with elastic bands. The exercise will realize three times per week, 20 minutes for day in total 60 minutes per week. With warming up for 5 minutes and 15 minutes of the specific training . The exercise will realize in 3 series with 10 repetitions and rest 30 seconds between series.
Experimental: Individual Resistance Exercise (IRE)
Intervention group will receive training protocol including warming up, stretching a specific resistance training with increase progressive load.
Other: Individual Resistance Exercise (IRE) - Intervention Group
Intervention group will receive warming up and stretching, and a specific resistance training with increase progress load. The exercise will realize three times per week, 20 minutes for day in total 60 minutes per week. With warming up and stretching for 5 minutes and 15 minutes of the specific training. The exercise will realize in 3 series with 10 repetitions and rest 30 seconds between series.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Need for Recovery
Time Frame: up to 4 months
Psychosocial risk factors and stress, resulting in work-induced fatigue, will be obtained by e Need for Recovery Scale (NFR).
up to 4 months
Fatigue
Time Frame: up to 4 months
1 RM test is the maximum amount of weight lifted once while performing a standardized exercise for muscle groups - elbow , knee and ankle flexors and extensors, trunk. A weight according to the maximum capacity is chosen. If a replay is completed, find the value of 1RM.
up to 4 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Musculoskeletal symptoms
Time Frame: Outcome measures will be assessed at baseline and after 4 months.
Musculoskeletal symptoms (pain, tingling or numbness) will be assessed using the Nordic Questionnaire for Musculoskeletal.
Outcome measures will be assessed at baseline and after 4 months.
Level of physical activity
Time Frame: Outcome measures will be assessed at baseline and after 4 months.
Questionnaire Baeck will be used to identify the level of habitual physical activity
Outcome measures will be assessed at baseline and after 4 months.
Perceived exposure
Time Frame: Outcome measures will be assessed at baseline and after 4 months.
The perception of workers risk factors that may contribute to the development of musculoskeletal complaints will be evaluated through the Job Factors Questionnaire.
Outcome measures will be assessed at baseline and after 4 months.
Physical Fitness Assessment
Time Frame: Outcome measures will be assessed at baseline and after 4 months.
The physical assessment will be consider adipometry (body fat percentage) others variables.
Outcome measures will be assessed at baseline and after 4 months.
Productivity
Time Frame: Outcome measures will be assessed at baseline and after 4 months.
Productivity is measured by a single item General Health Questionnaire and Performance at Work
Outcome measures will be assessed at baseline and after 4 months.
