Improvement of Motor Tasks: Effects of Verbal Encouragement and Music

June 6, 2024 updated by: Luca Puce, Universita degli Studi di Genova

Improvement of Motor Tasks Performance: Effects of Verbal Encouragement and Music - Key Results From a Randomised Crossover Study With Electromyography

This study employed a randomized crossover design to assess the impacts of three different experimental conditions-standard environment, music, and verbal encouragement-on performance in an isometric endurance task, with comparisons made between untrained and trained individuals. Interventions were spaced seven days apart. Measurements included muscle activity and fatigue, assessed via surface electromyography, and the duration of the task.

The isometric endurance task required participants to maintain a 90° elbow flexion while holding a dumbbell in a supine grip, weighted to 80% of their one-repetition maximum, on the dominant side. During the task, participants were to keep their back and head against a vertical wall, stand with feet shoulder-width apart, and firmly on the ground. The dumbbell was held with the dominant arm, and the other arm was kept neutral by the side. It was crucial to avoid any rocking or movements that would ease maintaining the position. The test began when the bar was handed to the participant in the correct stance and concluded once the arm's angle deviated by more than five degrees from the start.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Good general health,
  • No medical conditions that could interfere with their ability to perform the test safely and effectively.
  • To be considered exercised, participants had to have performed 150 minutes per week of vigorous intensity aerobic physical activity, in addition to muscle strengthening activities, for at least two days per week. Those who did not meet this standard were considered untrained.

Exclusion Criteria:

  • History of surgery on the arm, shoulder or adjacent areas that could limit the ability to perform the test.
  • Use of medication that affects muscle function or pain perception

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Task with verbal encouragement
Endurance isometric exercise performed with verbal encouragement
Other: Isometric Task
The task demanded that participants maintain their arm bent at a 90° angle while holding a dumbbell, which weighed 80% of their one-repetition maximum (1RM), in a supine grip on the dominant side of their body for the longest time they could.
Experimental: Task with music
Endurance isometric exercise performed with music
Other: Isometric Task
The task demanded that participants maintain their arm bent at a 90° angle while holding a dumbbell, which weighed 80% of their one-repetition maximum (1RM), in a supine grip on the dominant side of their body for the longest time they could.
Active Comparator: Task 1 without motivational feedback
Task without motivational feedback
Other: Isometric Task
The task demanded that participants maintain their arm bent at a 90° angle while holding a dumbbell, which weighed 80% of their one-repetition maximum (1RM), in a supine grip on the dominant side of their body for the longest time they could.
Active Comparator: Task 2 without motivational feedback
Task without motivational feedback
