An inherent risk of injury is also present due to frequent repetitions of high intensity movements that expose players to high joint and muscular forces ( 5). The sport of soccer imposes high physiological demand with aerobic endurance ( 24), speed, agility, strength and power key determinants of elite performance ( 22, 38). Knee valgus may be reliably used to screen elite youth male soccer players for this plyometric technique error and for test, re-test comparison. The results of this study suggest that although tuck jump total score may be reliably assessed in elite male youth soccer players, caution should be applied in solely interpreting the composite score due to the high within-subject variation in a number of the individual criteria. When each criteria was analyzed individually, Kappa coefficient determined that knee valgus was the only criterion to reach substantial agreement across the two test sessions for both groups. The typical error range reported for tuck jump total score (0.90 – 1.01 in pre and post-PHV players respectively) was considered acceptable. Technique was graded retrospectively against the 10-point criteria set out in the screening protocol using two-dimensional video cameras. A test, re-test design was used to explore the within-subject inter-session reliability.

25 pre and 25 post-peak height velocity (PHV) elite male youth soccer players from the academy of a professional English soccer club completed the assessment. The purpose of this study was to analyze the within-subject variation of the tuck jump screening assessment in elite male youth soccer players.
An example of a field-based screening tool is the repeated tuck jump assessment. The assessment of kinematic variables during jump-landing tasks as part of a pre-participation screen is useful in the identification of injury risk.
Ligamentous injuries most often occur during dynamic movements, such as decelerations from jump-landing maneuvers where high risk movement patterns are present. Tucker.Altered neuromuscular control has been suggested as a mechanism for injury in soccer players. In addition, keep in mind, as women age it's more and more difficult to improve bone density.” Note: the study did not include women with osteoporosis hopping may not be recommended in these cases, says Dr. “Women have to do the jumps daily to get the benefits. “Our study showed significant benefits over time,” says Dr. This new study shows a way to keep bones strong throughout life. To make matters worse, as we age we’re less likely to perform high-impact, bone-building activities. Five to seven years after menopause women may lose up to 20% or more bone density. Peak bone mass happens around age 25 and then declines. What it means: Although bone density increases most rapidly during adolescence, the process slows with age. Doesn't sound like a lot of gain? Consider this: the controls lost about 1.3% of their bone density over the same period. “Women jumped as high as they could from the floor,” says lead study researcher Larry Tucker, PhD. 5% by jumping 10 times a day, twice a day and taking short breaks (30 seconds) between each jump. The research: Sixty premenopausal women, ages 25 to 50, significantly increased their hip bone bone mineral density after four months by. The claim: Jumping 10 times a day twice a day provides greater bone-building benefits than running or jogging, reports a study in the American Journal of Health Promotion.
