“…Increase in serum calcium has been observed following physical activities [23]. The absence of significant effects with jumping exercise alone on serum total calcium in the present study was consistent with Maimoun et al [24] which reported that a single session of strenuous exercise did not result in any significant change in serum total calcium.…”

Open Access Research Articleactivity is through modification in bone turnover which occurs through two fundamentally different processes, i.e. modeling and remodeling with the activities of osteoblast and osteoclast cells in the mechanisms of bone formation and bone resorption [3]. A number of biochemical assays have been described for measuring serum and urinary concentration of markers of bone metabolism [4] that allow a good estimation of bone metabolic processes and have been established as useful parameters in assessing changes in bone turnover. To date, the mechanisms by which combined exercise and dietary intake lead to changes in bone metabolism are not fully understood.Nutritional supplementation is another main factor associated with bone health and development. Aoe et al. [5] reported that as compared to drugs that have a rapid effect, administration of nutrients related to bone metabolism is relatively safe and inexpensive. To date, the effects of different types of supplementation such as calcium, vitamin D, milk, soy and soy protein on bone mass, turnover and mineral density have been reported [6][7][8][9]. One of the nutrients that has long tradition of use within various medical systems and prescribed for variety of uses from ancient time is honey. Ariefdjohan et al. [10] reported that honey has the potential to increase calcium absorption after 2 days of acute feeding in rats. In addition, Hussain et al. [11] reported that honey has similar effects with hormone replacement therapy on bone densitometry in postmenopausal women. Therefore, it was hypothesized that honey may play a role in increasing bone health.Tualang honey is a wild, multi floral honey produced by Apis dorsata bees that form hives on the branches of giant trees named Tualang in the Malaysian rainforest, and it has been reported recently that ovariectomized rats that received Tualang honey showed greater improvements in trabecular bone structure than rats receiving calcium [12], implying the beneficial effects of Tualang honey supplementation on bone. Nevertheless to date, administration of Tualang honey in combination with exercise on bone health and antioxidant status in rats has not been investigated, thus the present study was proposed. AbstractPurpose: To investigate the effects of combined jumping exercise and honey supplementation on bone metabolism and antioxidant status in female rats.

Purpose: Bench-step exercise produces biomechanical movements beneficial to improve bone remodeling. However, no studies have confirmed the effects of bench-step exercise (BE) on bone formation and resorption. The goal of this study is to compare the effects of bench-step and walking exercise (WE) on changes in osteocalcin and CTX-1 levels. Methods: Fifty-nine sedentary post-menopausal women with osteopenia (T-score between À1 and À2.5) were randomly divided into two groups: WE group (n ¼ 29) and BE group (n ¼ 30). Subjects performed 12 weeks of exercise. The osteocalcin and CTX-1 levels were analyzed using enzyme-linked immunosorbent assay. Independent t-test or Wilcoxon test was used to analyze the osteocalcin and CTX-1 levels. The difference in changes in the osteocalcin and CTX-1 between the groups before and after was analyzed using Mann-Whitney test. Results: The results showed a significant increase in the osteocalcin and CTX-1 levels in both groups (P < 0:05). The increased levels of osteocalcin between groups were not statistically different (P > 0:367). The increase in CTX-1 resulting from BE was lower than that from WE (P < 0:048). Conclusion: This study indicates that BE may inhibit resorption stronger than WE.

“…In a study by Maïmoun et al 34 involving a group of elderly people who performed strenuous physical activity, a change in bone metabolism was observed using distinct markers (blood calcium ions). Serum changes also occurred in the group analyzed in this study, demonstrating that physical exercise promoted beneficial changes in bone metabolism.…”

Background & aim: Decreases in the organic form and function inherent to the aging process tend to reduce the functional capacity and the insulin-like growth factor I (IGF-1) hormone levels in the elderly. This study aimed to evaluate the effects of hydrogymnastics on IGF-1 serum levels and functional autonomy (FA) in elderly women.Methods: 28 elderly women were randomly divided into 2 groups: hydrogymnastics group (HG, n=14; age: 66.55±3.77years; BMI: 27.03±5.44kg/m 2 ) and control group (CG, n=14; age: 66.33±4.52years; BMI: 29.82±4.96kg/m 2 ). The intervention with hydrogymnastics was performed 3 times per week during 12 weeks. Each session was composed of warming up, main part and cool-down, totaling 50 minutes of duration. The IGF-1 levels were analyzed by chemiluminescence. The GDLAM protocol of FA was applied -walking 10 m (W10m); rising from the sitting position (RSP); rising from a ventral decubitus position (RVDP); sitting in, rising from, and walking around a chair (SRWC); and putting on and taking off a t-shirt (PTTs) -and the overall autonomy index (AI) was calculated. Results:The HG showed a significant increase in IGF-1 serum levels after the intervention when compared to CG. The execution times in the GDLAM protocol tests were significantly lower in the HG, except in the SRWC, and the HG also presented a significant improvement in the AI post-intervention (p<0.05). Conclusion:The 12-week hydrogymnastics intervention contributed to an increase in IGF-1 serum levels and to improve the performance in activities of daily living (ADL) in the elderly women.
