About this study

Official title: Localized Muscle Resistance Test: Identification and Use of Parameters for Prescription of Exercise Resisted in Different Evaluation Tools

Introduction: Verification of the progression of individuals submitted to training programs is performed by diagnostic tests with a focus on strength and muscular endurance. Among the tools used are the elastic bands, the halter, the pulley, the digital dynamometer and, additionally, the isokinetic dynamometer, considered the gold standard of evaluation. However, there is a lack of standardization in assessments and scarcity in the exploration of some tools and some muscle groups. Observation is often restricted to a particular study design and makes comparisons difficult even with the use of the same tool. Thus, to include different clinical possibilities in the same scenario can enrich the discussion about the topic. Objective: To develop and analyze the validity and reliability of a maximal muscle strength test for the external rotator muscles of the shoulder in five tools; To develop and analyze the validity and reliability of a localized resistance test for the external rotator muscles of shoulder in three different percentages of maximum strength (60%, 70%, 80%) in four tools; To characterize by means of the physiological response the localized muscular endurance test with the load that presents with the highest reliability values in each tool. Method: The study will consist of a sample of 50 participants of both genders, and will be performed in 3 steps: (1) Validation and reliability of the maximum muscle strength test; (2) Reliability of the muscular endurance test (MET); (3) Physiological characterization of the muscular endurance test (MET). Stage 1 will be held in 3 sessions (familiarization, test and retest) in which participants will perform 5 tests of maximum strength with different tools (elastic bands, pulley, halter, digital dynamometer and isokinetic dynamometer). Stage 2, consisting of 6 sessions, will be tested and retest of a muscular endurance test with different loads (70%, 80% and 90% of maximum force) with the same devices of step 1, except the digital dynamometer. In Step 3 participants will be selected with the lowest variations between the test and retest in the variable "time" to perform the physiological characterization of the test with the different tools. In order to observe the physiological response, we will analyze the lactic anaerobic (lactate concentration), allelic anaerobic (post-exercise oxygen uptake (EPOC) and aerobic (VO 2 values) parameters). The statistical package SPSS Statistics 22.0 will be used to conduct the analyzes. Key words: Fatigue, Physical resistance, Muscle strength, Lactate.

Study groupRoleWhat they receive
strength testThe maximum strength test of external shoulder rotators will be performed on 5 different tools with specific protocols.
Receives: Diagnostic Test: Maximal muscle strength Test
Endurance testTest designed by the Laboratory of Sports Physical Therapy (LAFIDE) of FCT / UNESP - Presidente Prudente, used in the prescription of training for gain of localized muscular endurance. Will be realized in the tools: Isokinetic dynamometer, elastic bands, pulley and halter. The test will consist of the maximum possible repetitions (until fatigue) with loads of 70%, 80% and 90% of the maximum force (in different sessions).
Receives: Diagnostic Test: Exhaustion test

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximal force (kilograms)

    The maximum force of the participant shall be measured with the values presented in kilogram

    Measured: Stage 1 - 0 minutes after strength test

  2. Time (seconds)

    Measured: Stage 2 - 0 minutes after Endurance test

  3. Number of repetitions

    Measured: Stage 2 -0 minutes after Endurance test

  4. Anthropometric evaluation

    To determine the value corresponding to the body mass, the volunteers will be evaluated by a digital scale (Tanita BC554, Iron Man / Inner Scaner - Tanita, Illinois, United States). Stature values will be obtained by means of a stadiometer (Sanny - American Medical do Brasil, São Paulo, Brazil). From these values it will be possible to calculate the Body Mass Index (BMI), determined by the ratio of weight to height squared.

    Measured: Stage 1 - 10 minutes before stregth test

  5. Psychological Questionnaire

    The questionnaire aims to subjectively document physical and metal readiness scores for exercise, fatigue, vigor, drowsiness, and muscle pain. Participants will be instructed to mark a dash on a visual analogue scale of 10 centimeters between two extremes, zero being "least possible" and 10 indicating "most possible" for each classification60. This questionnaire will be applied at the beginning of all sessions.

    Measured: Stage 1 - 10 minutes before stregth test

  6. International Physical Activity Questionnaire (IPAQ)

    The IPAQ questionnaire is an instrument developed to estimate the level of habitual practice of physical activity. Sedentary - Does not perform any physical activity for at least 10 continuous minutes; Insufficiently Active - Individuals who engage in physical activity for at least 10 continuous minutes per week, but insufficiently to be classified as active. A) Perform 10 continuous minutes of physical activity, following at least one of the following criteria: frequency - 5 days/week or duration - 150 minutes/week; B) Does not meet any of the criteria of the recommendation cited in under-active individuals A; Active - a) vigorous physical activity - ≥ 3 days/week and ≥ 20 minutes/session; b) moderate or walking - ≥ 5 days/week and ≥ 30 minutes/session; c) any added activity: ≥ 5 day/week and ≥ 150 min/week; Very Active - a) vigorous - ≥ 5 days/week and ≥ 30 min/session; b) vigorous - ≥ 3 days/week and ≥ 20 min/session + moderate and or ≥ 5 days/week and ≥ 30 min/session.

    Measured: Stage 1 - 10 minutes before stregth test

  7. Borg's Perception of Effort Scale

    The degree of subjective effort reported by the participants in relation to the upper limbs will be analyzed using the Borg scale of perception of effort of 6 to 20 points, 6 corresponding to the "very easy" and 20 to "exhaustive".

    Measured: Stage 2 - 0 minutes after endurance test in all tools

  8. Perceived effort

    The perceived exertion of the resisted exercise will be evaluated through the OMNI Resistance Exercise Scale for Perceived Effort62,63, which consists of an ordinal scale of 0 to 10, 0 being extremely easy and 10 extremely difficult.

    Measured: Stage 2 - 0 minutes after endurance test in all tools

  9. Recovery Perception

    The perception of recovery of the dominant lower limb will be evaluated through the Likert Scale of Recovery Perception, which consists of a scale with values between 1 and 10 points, 1 corresponding to no recovery and 10 to fully recovered

    Measured: Stage 2 - 10 minutes after endurance test in all tools

  10. Participation of the anaerobic parameter

    The total participation of the anaerobic parameter (PANA) will be calculated by the sum of the lactary anaerobic (CLAC) and alactic (CALA) contributions, analyzed by [lac] and the excess of post-exercise oxygen consumption (EPOC), respectively.

    Measured: Stage 3 - During endurance test, until 7 minutes after test
