Brief Summary

26 Tae Kwon Do athletes performed a vigorous exercise program on the isokinetic dynamometer twice in a period of 10 days, each time on a different extremity. In this way two groups of 26 individuals each were created, with the same individuals alternating. In the massage group (MG) a sport massage was applied between the sets while in the control group (NMG) the break was passive.

Conditions

Athletic Performance

Keywords

sport massage; delayed onset muscle soreness; muscles recovery; continuous concentric eccentric exercise

Outcome Measures

Primary Outcomes (4)

• Changes in Active Knee Range of Motion (ROM)

  The ROM of knee flexion and extension was measured before and after the exercise program application in both trials. In particular, the active knee extension was measured in the supine position and the active flexion in the prone position using a universal type goniometer.

  day 1: pre-treatment, after- treatment, day: 10 pre-treatment, after- treatment

• Changes in creatine kinase (CK) levels in blood plasma

  Blood samples were taken before and 24 hours after the isokinetic protocol to determine whether the exercise program caused fatigue and muscle damage. The blood sample was analyzed to determine CK activity levels in blood plasma using an in-vitro quantitative assay followed by a photometer

  day 1: pre-treatment, after- treatment, day: 10 pre-treatment, after- treatment

• Changes in thigh circumference

  The circumference of the thigh was measured with a tape measure before the test and after the exercise program at fixed spots at a distance of 10 and 20 cm from the center of the patella

  day 1: pre-treatment, after- treatment, day: 10 pre-treatment, after- treatment

• Changes in Delayed Onset Muscle Soreness (DOMS)

  The DOMS measurement for the lower extremities (L-DOMS) was performed with the VAS scale 24, 48, 72 and 96 hours after the completion of the program. The VAS scale was tentative where 1 corresponded to "no soreness" and 10 to "very, very sore". The L-DOMS was assessed according to Doma et al1,22 and according to Jakeman et al, through questioning after they completed a body weight squat until their knees were flexed to approximately 90°

  day 1: 24, 48, 72 and 96 hours after-exercise, day 10: 24, 48, 72 and 96 hours after-exercise

Secondary Outcomes (1)

• Changes in concentric and eccentric torque

  day 1: pre-treatment

Study Arms (2)

Massage group (ME)

EXPERIMENTAL

A sport massage was applied between the sets of an intense isokinetic exercise protocol for knee extensor muscles

Other: Isokinetic intense exercise protocol; Other: Massage treatment

Control

ACTIVE COMPARATOR

the break between the sets of an intense isokinetic exercise protocol for knee extensor muscles was passive

Other: Isokinetic intense exercise protocol

Interventions

Isokinetic intense exercise protocol OTHER

The isokinetic protocol included 6 sets of 10 maximum efforts at 60 °/s of one leg with a 2-minute break between the sets.

Control; Massage group (ME)

Massage treatment OTHER

Massage consisted of stroking (30") and petrissage (50") for muscle relaxation, then friction (10"), pincement and clapping (30") to prepare muscles for the next set.
