About

In the study, 34 healthy sedentary male volunteers were randomly divided into two groups as NM (n = 17) and SHAM-NM (n = 17). After the initial evaluation of the individuals, femoral nerve NM and placebo NM techniques were administered three sets a day with ten repetitions for three days a week for three weeks. Three days after the end of the applications, the second evaluations were made and the DOMS creation protocol for the quadriceps femoris (QF) muscle was initiated. In order to trigger DOMS in individuals, 30 sets and 10 repetitions of eccentric knee extension (35°-95° flexion angles, 30°/sec speed) were performed on the dominant lower extremity with an isokinetic dynamometer. Baseline evaluations were repeated immediately after the DOMS protocol, and at hours 24, 48, and 72. During evaluations, muscle damage (serum creatine kinase (CK), lactate dehydrogenase (LDH), and inflammation (interleukin-6 (IL-6), tumor necrosis factor-alpha) biomarkers, pain (activity), pressure pain threshold, and performance (one-leg jump, vertical jump) parameters were measured.

Full description

The aim of this study was to investigate the effects of neurodynamic mobilization (NM) technique on muscle damage and inflammation biomarkers, and pain, pressure pain threshold, and functional status in delayed onset muscle soreness (DOMS). In the study, 34 healthy sedentary male volunteers were randomly divided into two groups as NM (n = 17) and SHAM-NM (n = 17). After the initial evaluation of the individuals, femoral nerve NM and placebo NM techniques were administered three sets a day with ten repetitions for three days a week for three weeks. Three days after the end of the applications, the second evaluations were made and the DOMS creation protocol for the quadriceps femoris (QF) muscle was initiated. In order to trigger DOMS in individuals, 30 sets and 10 repetitions of eccentric knee extension (35°-95° flexion angles, 30°/sec speed) were performed on the dominant lower extremity with an isokinetic dynamometer. Baseline evaluations were repeated immediately after the DOMS protocol, and at hours 24, 48, and 72. During evaluations, muscle damage (serum creatine kinase (CK), lactate dehydrogenase (LDH), and inflammation (interleukin-6 (IL-6), tumor necrosis factor-alpha) biomarkers, pain (activity), pressure pain threshold, and performance (one-leg jump, vertical jump) parameters were measured.

Enrollment: 34 patients

Sex: Male

Ages: 18 to 32 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Being in the age range of 20-32 years.
• Being male (Because gender difference in the magnitude of eccentric exercise-induced muscle damage might exist as shown in previous studies, only men were recruited in the present study.)
• Being inactive according to activity guidelines published by the American College of Sports Medicine (less than 30 minutes of moderate physical activity as five times a week).

Exclusion criteria

• Absence of DOMS symptoms,
• History of vascular disease,
• Recent injury or surgery to their lower extremity,
• Neurological impairments and regular use of pain and inflammation medications.

Study Group

Experimental group

Description:

Femoral nerve neurodynamic mobilization group T1: Baseline measurements were made and blood samples were taken for biochemical analysis. NM and placebo NM techniques were applied for three weeks, three times a week, and totaling nine visits. At the end of the third week, it was waited 3 days to eliminate the acute effect of NM. T2: Baseline measurements and blood samples were repeated a second time. The protocol for establishing the DOMS was applied on the same day. T3: Following the protocol for inducing the DOMS, the baseline measurements were repeated for the third time without any interruption, and the blood sample was taken. T4-T5-T6: The first measurements and blood sample collections were repeated for the fourth, fifth and sixth times, respectively, 24h, 48h, 72h after the DOMS protocol.

Other: Femoral nerve neurodynamic mobilization
