Background: Regular physical activity and proper nutritional intake are crucial for bone health. However, it is unclear if this health benefit is maintained after the removal of these stimuli. This study investigated the combined effects of aerobic dance exercise and honey supplementation, followed by their subsequent cessation on bone metabolism markers and antioxidant status in females. Methods: Forty-eight young female college students were assigned into four groups: i) 16S (16 weeks of sedentary activity); ii) 8E×8S (8 weeks of exercise followed by 8 weeks of sedentary activity); iii) 8H8S (8 weeks of honey supplementation followed by 8 weeks of sedentary activity) and iv) 8E×H8S (8 weeks of combined exercise and honey supplementation followed by 8 weeks of sedentary activity). Blood samples were collected from the participants prior to the intervention, at week 8 and at week 16 for the analysis of bone metabolism markers and antioxidant status. Results: At the mid test, bone speed of sound (SOS) (P < 0.01), serum alkaline phosphatase (ALP) (P < 0.001) and serum osteocalcin (P < 0.01) were significantly higher in the 8E×H8S group as compared to 16S group. After 8 weeks of cessation of exercise and honey supplementation, bone SOS was also significantly higher (P < 0.001) in the 8E×H8S group as compared to 16S group. In addition, the serum total calcium (P < 0.001), serum ALP (P < 0.01), total antioxidant status (TAS) (P < 0.01) and glutathione (GSH) (P < 0.01) in the 8E×H8S group were significantly higher at the post-test as compared to their respective pre-test values. Conclusion: These findings demonstrate that there was improved maintenance of the beneficial effects induced by 8 weeks of combined exercise and honey supplementation on bone properties and the antioxidant status after 8 weeks of cessation of exercise and honey supplementation as compared to exercise and honey supplementation alone.
The purpose of the present study was to investigate if 12 weeks of isokinetic resistance training programme at two different angular velocities (120 and 240°/s) would improve functional abilities of patients with grade III anterior cruciate ligament (ACL) injury without reconstruction. 19 subjects were recruited to the study. They were randomly assigned into three groups: control (6 subjects), 120°/s intervention group (6 subjects) and 240°/s intervention group (7 subjects). The first invention group (120°/s trained group) aged 36.8 ± 7.9 years participated in the prescribed training along with the existing conventional physiotherapy treatment. The second intervention group (240°/s trained group) aged 33 ± 11.4 years also participated in the prescribed training along with the existing conventional physiotherapy treatment. The control group aged 33.5 ± 6.8 years continued with the conventional physiotherapy only. The physiotherapy treatment was carried out by the subjects two times per week. The subjects in both the intervention groups were required to perform the isokinetic resistance training two times per week after the physiotherapy sessions. The results show that there was significant improvement (p<0.05) of physical function in both intervention groups and the control group at post-training (after 12 weeks). However, there were no significant differences between the control group and intervention groups. These data indicate that isokinetic resistance training improved physical functions of patients with grade III ACL injury. Nevertheless, the existing physiotherapy programme also elicited similar benefits to these patients. Therefore, it is concluded that isokinetic resistance training combined with existing conventional physiotherapy and physiotherapy treatment alone are beneficial as a rehabilitation programme for patients with knee grade III ACL injury.
