Objectives: The aim of this study was to investigate the effectiveness of whole-body vibration exercise (WBVE) and core stabilization exercise (CSE) on pain, muscle strength, and functional recovery in patients with chronic non-specific low back pain (NLBP).
Patients and methods: Between June 2016 and July 2017, a total of 74 patients with NLBP (12 males, 62 females; mean age: 44.7±8.9 years; range, 24 to 64 years) were included in this prospective, randomized-controlled study. The patients were randomly assigned to WBVE group (WBVEG, n=25), CSE group (CSEG, (n=25), and home exercise group as the control group (CG, (n=24). All groups performed 24 sessions of exercise for a total of eight weeks. Clinical outcome was measured using the Visual Analog Scale (VAS), Roland-Morris Disability Questionnaire (RMDQ), computerized isokinetic muscle strengths (IMS) and progressive isoinertial lifting evaluation (PILE) test.
Results: The VAS and RMDQ scores in WBVEG and CSEG statistically significantly decreased (p<0.05). The difference between the pre-treatment and at three-month VAS scores during intense activity were significantly different in both WBVEG and CSEG than the CG (p<0.05). The IMS values, except for the isokinetic flexion total work (IKFTW), increased significantly in all three groups (p<0.05). The IKFTW values increased significantly in the WBVEG and CSEG (p<0.05). A statistically significant increase in the functional work performance with PILE was observed in all three groups (p<0.05). The differences between the pre-treatment and three-month PILE test (ground to back and back to shoulder) were significantly different in both WBVEG and CSEG than the CG (p<0.05).
Conclusion: In the treatment of chronic NLBP, WBVE and CSE appear to be effective in pain and functionality. Although there was a significant improvement in muscle strength and functional work performance in all three groups, greater improvements were observed in the WBVEG and CSEG than the CG.
The mechanisms that regulate the development of human physiological cardiac hypertrophy remain poorly understood. The renin-angiotensin system, which is modulated by genetic polymorphism, plays an important role in the regulation of vascular tone and myocardial hypertrophy. Although a few studies have analyzed the association of angiotensin-converting enzyme (ACE) polymorphism and left ventricular (LV) hypertrophy in isotonic exercise-trained subjects who developed eccentric cardiac hypertrophy, there has been no research done in power athletes who developed concentric cardiac hypertrophy. We have hypothesized that ACE genotypic modulation characteristics may affect LV mass in power athletes. This study included 29 elite Caucasian wrestlers (mean age, 22.6 years) and 51 age-matched sedentary subjects. According to the absence or presence of the insertion segment in the polymerase chain reaction (PCR) product, the subjects were classified as homozygous deletion-deletion (DD), insertion-insertion (II), or heterozygous insertion-deletion (ID). The association of LV hypertrophy with ACE gene insertion/deletion (I/D) polymorphism was analyzed. Left ventricular mass and index were determined by echocardiography. Angiotensin-converting enzyme genotyping was performed on peripheral leukocytes using the polymerase chain reaction technique. The study and control group subjects were similar in height and weight. Left ventricular hypertrophy in the athletes was more apparent than in the controls. Angiotensin-converting enzyme genotype II frequency was 17.2% (5) in the athletes, 17.6% (9) in the controls; ID frequency was 51.7% (15) in the athletes, 56.8% (29) in the controls; and the DD frequency was 31% (9) in the athletes and 25.4% (13) in the controls. Left ventricular mass and mass index were found to be higher in genotype DD (126.2 +/- 2.9g/m2) than genotype II (85.5 +/- 4.0g/m2) or genotype ID (110.1 +/- 2.3g/m2) in the athletes (P < 0.001). Furthermore, maximal oxygen consumption in genotype DD was found to be higher than in II and ID. An association was found between ACE gene I/D polymorphism and LV hypertrophy in strength-trained athletes.
This study demonstrated that OUES is significantly correlated with peak VO and it does not require the performance of maximal exercise and can be used together with peak VO in this patient population when there is difficulty in making decision for surgery in patients with lung cancer.
Uncomplicated diabetes does not seem to accelerate aging-related muscle mass or strength loss. Exercise test parameters may be useful markers in the screening of sarcopenia.
