Brief Summary

The purpose of this research study is to determine if the application of ice, control group, or a muscle stimulation program from the Compex® series can help reduce or eliminate delayed muscle soreness from performing leg extension and flexion. Individuals will complete a health history questionnaire to determine if they qualify for this study. We will measure your leg girth with a measuring tape and take a pain measurement of your hamstrings by using a spring to press down on your leg. Individuals will then warm-up on a bike without resistance for 5 minutes followed by 10 regular leg extension and flexion exercises. Individuals will then perform 6 sets of 10 leg extension and flexion exercises on a biodex machine (similar to leg curl machines in the gym). Individuals will perform each set to the maximum effort of their capables. After each set of 10 individuals will have a 2 minute rest. We will ask you to rank your leg soreness on a scale from 1-10. Individuals will then be assigned to a modality of either ice, control group or compex. Individuals will perform the modality (ice, control, compex) we assign you to until you are no longer sore. Over the next five days individuals will return to measure their level of soreness, leg girth and pain pressure. This study will examine the following hypotheses: H1: There will be no difference in pressure pain threshold after using the Compex compared to other groups. H2: There will be no difference in perceived soreness after using the Compex compared to other groups. H3: There will be no difference in muscular strength after using the Compex compared to other groups. H4: There will be no difference in active range of motion after using the Compex compared to other groups.

Outcome Measures

Primary Outcomes (1)

• Pain Scores on the Visual Analog Scale

  Visual Analog Scale for Muscle Soreness scale The scale for measuring the intensity of muscle soreness will be a 10 cm visual analog scale, spaced by one centimeter increments from one to 10. Ten will represent the maximum amount of soreness and zero represents no soreness at all. Subjects will be asked to complete this scale once per day at the same time of day until the soreness has dissipated. The Visual Analog Scale for muscle soreness is measured as 'scores on a scale'.

  Day 1 through Day 5

Study Arms (3)

'Compex unit's Active Recovery® program'

EXPERIMENTAL

The Compex electrical stimulation system utilized in this study is intended for external application with electrodes to create a muscular contraction and help enhance recovery after eccentric muscular activity.

Device: Compex unit's Active Recovery® program

Ice application

OTHER

A randomized pre and post-test research design will be used to compare three interventions (control, ice, compex) to alleviate the physical symptoms of delayed-onset muscle soreness (DOMS).

Other: Ice application

Control

NO INTERVENTION

This is a control group where subjects will not perform an intervention.

Interventions

Compex unit's Active Recovery® program DEVICE

Compex unit's Active Recovery® program will be performed for 15 minutes once per day.

'Compex unit's Active Recovery® program'

Ice application OTHER

Participants will apply ice on their hamstring for 15 minutes three times per day until muscle soreness is no longer present

Ice application
