The Effect of Eccentric Training on Anthropometrics, Physical Fitness &

Status Recruiting

Clinical Trial Summary

The purpose of this study is to examine the effects of aerobic eccentric training in overweight and obese children.

Clinical Trial Description

recent studies have shown that similarly to regular exercise, aerobic ECcentric Contraction (ECC) exercise induces changes in the musculoskeletal system while using lower energy consumption, due to the fact that eccentric training creates greater force in the muscle.

most of the studies in this subject were done on healthy or overweight adults. therefore, the effect of aerobic eccentric training on children is still unknown. this study wants to test the impact of eccentric training on overweight and obese children.

this study will include approximately 100 overweight and obese children (boys and girls), aged 5-18 years. participants will be recruited from the population of overweight children from children sports medical center 'Meir' in Kfar Saba, Israel. participants will be randomly divided into two groups (intervention and control). Participants and their parents will sign a consent form before entering the study.

Each participant will undergo a series of tests including: anthropometrics (height, weight, bmi, body composition by BIA), fitness tests (Maximal distance achieved in a 12min outdoor run\walk, Vertical jump, Standing long jump, 4X10 meter sprint run), quadriceps and hamstrings strength test (hand-held dynamometer MicroFet2), bone strength (bone sonometer), ankle and tibial kinematic(accelerometers+ video of foot strike).

Intervention group will then perform an 8 week (16 sessions) ECC training program on a decline treadmill, the program will include two weeks of habituation to lower as possible DOMS (delayed onset muscle soreness) and possible injuries, training length and intensity will be gradually increasing over the time of the program, maximal negative gradient will be -15% at the end of the program.

Control group will perform the same amount of training (volume, intensity and frequency) on a neutral gradient surface. After completing the training program each participant will perform again the series of tests. Once all the data is collected, statistical test will be performed in order to learn about the effect of ECC training program on overweight and obese children. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
