Investigating the effect of plyometric exercises with and without blood flow restriction on bone metabolism markers
Design
People are asking for participation in the registration scheme. Then, among them, the qualified individuals are selected and during a briefing, they will first familiarize with the type of plan, objectives and implementation method, including the method of performing a preliminary test (pre-test), participating in training, post-test and blood tests. In this session, the participants complete the consent form of the company in the test and form of the public health questionnaire and will assure them that the information they receive will be completely confidential. Subjects will be randomly divided into exercise and exercise groups with limited blood flow. After performing biochemical tests and initial anthropometric measurements, the groups will have pliometric and pleometric blood flow limitation for 4 weeks. Finally, the tests were retested after 4 weeks of training and the data were analyzed.
Settings and conduct
Participants will complete 3 exercises for four weeks a week and 25 minutes each session for the first week, which will last 40 minutes in the last week, at the sports halls Shahid Chamran University.
Participants/Inclusion and exclusion criteria
Missing more than one session in the exercises
Participate in sports meetings other than sports presentations
Intervention groups
The present study will be conducted on two groups of high intensity plyometric exercises and a plyometric group with blood flow limitation. One of the training groups will undergo intensive training for 4 weeks and the other will practice low intensity plyometric exercise with limited blood flow.
Main outcome variables
Exercise with low levels of blood circulation can lead to improved bone metabolism and, therefore, prevention of osteoporosis.
