Abstract

Exercise training can improve blood pressure in normotensive, prehypertensive, and hypertensive subjects. One of the mechanisms of blood pressure reduction in hypertensive patients with obesity is through weight loss. This study aimed to examine the effect of exercise training on bodyweight and the relationship between weight loss and reduction of blood pressure. An experimental pre-post test design without controls was used to evaluate the effect of exercise training on weight loss. The study involved 89 elderly aged 50 years or more, consisting of 40 men and 49 women, who were members of Senayan Sport Fitness Club and had been exercising for at least three months. Exercise training was programmed and performed three times a week, consisting of aerobic (walking, jogging, static cycling), and resistance exercise. All exercise was performed for one to two hours with mild to moderate intensity. Blood pressure and body weight were obtained from medical records. Paired t-test showed that systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse pressure (PP), and body mass index (BMI) were significantly lower after training [(systolic, 126.3 ± 2.9 vs 122.3 ± 2.7, p=0.02), (diastolic, 80.2 ± 3.1 vs 77.2 ± 2.4, p=0.00), (MAP, 95.6 ± 4.6 vs 92.2 ± 3.4, p=0.00), (PP, 46.1 ± 4.2 vs 45.1 ± 3.6, p=0.04), (BMI, 24.5 ± 2.9 vs 23.6 ± 2.9, p=0.04)]. Duration of training was the most influential factor affecting rBMI, (Beta = 0.38; p=0.00). Exercise training could lower BMI and the reduction in diastolic blood pressure was higher for the subjects aged 70 years and over.

Abstract

Low back pain (LBP) is a common problem in adult life, since despite its benign nature it is commonly associated with incapacity, productivity loss due to sick leave, and correspondingly high costs to the individual worker. Psychosocial and lifestyle factors and work-place exposures have been implicated in the onset of symptoms. Heavy physical work, static work postures, frequent bending and twisting, lifting and postural movements, repetitive work, and whole body vibrations are occupational factors associated with LBP. The usual classification of LBP is related to the duration of the complaints (acute, subacute, and chronic). However, these terms fail to take into account several clinically important aspects of the course of LBP, which is frequently recurrent and thus neither acute nor chronic. More realistically, LBP should be classified as specific and nonspecific. Approximately 90% of LBP cases have no identifiable cause and is designated nonspecific LBP. However, despite its high prevalence, the etiology and nature of nonspecific LBP are not yet well understood. Its pathophysiology remains complex and multifaceted. Multiple anatomic structures and elements of the lumbar spine (e.g. bones, ligaments, tendons, discs, and muscles) are all suspected of playing a role. Many of these components of the lumbar spine have sensory innervations that can generate nociceptive signals in response to tissue-damaging stimuli. Other causes could be neuropathic (e.g. sciatica). Some cases of LBP most likely involve mixed nociceptive and neuropathic etiologies.

Abstract

The kelakai fern (Stenochlaena palustris) contains bioactive substances, such as flavonoids, steroids, and alkaloids. The kelakai is used by the Kenyah Dayak communities for the treatment of anemia, fever, and cutaneous disorders. Fever is increased temperature regulation of the body, which process indirectly increases the production of peroxides, leading to peroxidative stress. The aim of this research study was to evaluate the influence of an aqueous extract of the kelakai fern on peroxidative stress in the hoary marmot (Marmota caligata) with experimentally-induced fever. This was a true experimental study, with post test-only and control group design, involving 6 groups, each made up of 4 animals. Peroxide concentration was measured by a modification of the FOX2 method and peroxidase activity by the Kanehira method. The kelakai extract was administered to the animals by gavage at weight-adjusted dosages between 7.75 x 10-4 mg/kg body weight to 1.24 x 10-2 mg/kg body weight. Data were analyzed using singe linear regression test. The results showed that kelakai extract dose significantly reduced the peroxide levels, regression equation with the Y = 2.513-106.03 X (R2 = 0.8057), indicating that 80.5% variation of peroxide levels is predicted by the kelakai extract dose. From the results we conclude that kelakai aqueous extract decreases peroxide levels in hoary marmots with experimentally-induced fever.
