Effects of Whole-Body Electromyostimulation on Golf Performance

January 7, 2021 updated by: University of Erlangen-Nürnberg Medical School

Effects of 16 Weeks of Whole-Body Electromyostimulation on Stability, Strength and Golf Performance in Amateur Golfers - A Randomized Controlled Study

Golf is becoming increasingly popular in Germany. However, the biomechanical and motor challenge of golf should not be underestimated. Nevertheless, only very few amateur golfers carry out serious preparation and conditioning as part of a strength/stabilization program. The main argument for this limitation is the aspect of "limited time resources". A solution to this problem could therefore be the time-effective and highly individualizable whole-body electromyostimulation (WB-EMS) technology. The aim of the present study is to evaluate the effectiveness of 16 weeks of WB-EMSapplication on maximum strength of the lower extremities, trunk stability and (golf) handicap in male amateur golfers in a (randomized) controlled setting.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • golf amateurs with a history if golf > 2 years
  • no WB-EMS application during the last 12 months

Exclusion Criteria:

  • contraindications for WB-EMS (in doubt assessment by study physician)
  • contraindications for MRI (in doubt assessment by study physician)
  • resistance exercise training for more one 60 min/week during the last 12 months

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
18 hole golf score
Time Frame: through study completion, on average 4 months
Average golf score of 5 rounds on a 18 hole course (supervised)
through study completion, on average 4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hip-/leg extensor strength
Time Frame: At baseline and after 16 weeks
Changes of maximum dynamic hip-/leg extensor strength as determine by an isokinetic leg press
At baseline and after 16 weeks
Trunk strength
Time Frame: At baseline and after 16 weeks
Changes of maximum isometric trunk strength (index of trunk extension/-flexion; lateral flexion and trunk rotation) as determined by an isometric testing device
At baseline and after 16 weeks
Muscle density at the mid-thigh
Time Frame: At baseline and after 16 weeks
Muscle density at the mid-thigh as determined by MRI
