Summary

The aim of the project is to study the effects on bone remodeling induced by training carried out with the trampoline in order to evaluate the reduction of the resorption itself and therefore the onset of osteoporosis in women.

Detailed description

Bone mineral density is modified by various factors and in particular by diet, nutritional status and exercise recommended to preserve or increase bone mass in adults. The degree of bone formation and resorption can be assessed by measuring bone resorption markers in the blood or urine. To date, there is no information about the effect of training with an elastic trampoline on the reduction of bone resorption. The aim of the project is to study the effects on bone remodeling induced by training carried out with the trampoline, in order to evaluate the reduction of the resorption itself and therefore the onset of osteoporosis in women. To examine whether exercise affects bone remodeling, the C-terminal telopeptide bone resorption markers (CTX) and osteocalcin formation marker will be measured. For the evaluation of bone metabolism osteocalcin parathyroid hormone, Calcitonin, Vitamin D, Calcium, albumin, Phosphate, Potassium markers will be evaluated. The markers can be detected in serum. Women with no previous experience with the trampoline activity will participate in the project randomly assigned to the experimental training group (Jumpers) or to the control group, who will not do any training during the observation period (not Jumpers). The control group will be inserted in order to compare the data and further verify the efficiency of the treatment. Blood samples for bone resorption assay will be collected on the first day of training with the trampoline and 20 weeks. Each training session will be monitored by detecting heart rate (heart rate monitor) and subjective perception of fatigue (Borg scale). Each subject will be subjected to two venous blood samples taken at the beginning of the observation and at the end. The samples thus obtained will be transported in certified containers for the safe transport of biological samples, and, subsequently, processed by the experimenters at the laboratories of the Molecular Biology section of the University of Palermo. Serum and plasma will be obtained from each blood sample. All information thus obtained will be recorded in a database in which each person will be identified with a numerical code, in order to comply with current privacy regulations. Body weight, Barefoot standing height, Body mass index, Body composition will be measured in the different groups of study. Blood samples will be collected from the different groups of study. Samples will be analyzed and compared for Osteocalcin, parathyroid hormone, CTX, Calcitonin, Vitamin D Calcium, albumin, Phosphate, Potassium.
