Title: Performance-Based Correlates to Vertical Jump Height and Power Values
Authors: J. F. Caruso, A. G. Barbosa, E. V. Gutierrez, M. W. Keller, S. D. Vickers, J. L. Martin, J. D. McArtor, R. A. Baptista, A. N. Clark, J. O. West, R. H. Walker and J. S. Daily
Abstract: We examined what types of performance-based variables (kinetic, temporal, force-time integrative, expressed relative to body mass) are the best correlates to vertical jump height and power values. Men (n = 117) performed vertical jumps on an instrumented platform placed aside a Vertec; both devices obtained data as jumps were performed. Vertec values were used to identify jump height and power, each of which served as criterion measures. The platform provided six performance-based variables from the takeoff phase of jumps; they were used to predict the variance per criterion measure via multivariate regression. With either jump height or power as a criterion each multivariate analysis, with corrections for multiple testing, revealed a significant (p < 0.05) amount of variance correlated to our performance-based independent variables. Univariate correlations showed peak force and area under the curve were the best predictors of jump height, as well as power, variance. Our results concur with outcomes from trials that employed similar subjects. We conclude kinetic and force-time integrative variables are the best correlates to vertical jump prowess when performance-based measures are derived from an instrumented platform.

Abstract: Rugby is a sport which is growing in popularity. A contact sport par excellence, it causes a significant number of injuries. In rugby union, there are 30 to 91 injuries per 1,000 match hours. This epidemiological review of injuries incurred by rugby players mentions the position and type of injuries, the causes, time during the match and season in which they occur, the players' positions and the type of surface as well as the length of players' absences following the injury.

Abstract: Aim: To describe lower extremity injuries for badminton in New Zealand. Methods: Lower limb badminton injuries that resulted in claims accepted by the national insurance company Accident Compensation Corporation (ACC) in New Zealand between 2006 and 2011 were reviewed. Results: The estimated national injury incidence for badminton injuries in New Zealand from 2006 to 2011 was 0.66%. The 1,909 lower limb badminton injury claims cost NZ$2,014,337. The age-bands frequently injured were 10-19 (22%), 40-49 (22%), 30-39 (14%) and 50-59 (13%) years. Sixty five percent of lower limb injuries were knee ligament sprains/tears. Males sustained more cruciate ligament sprains than females (75 vs 39). Movements involving turning, changing direction, shifting weight, pivoting or twisting were responsible for 34% of lower extremity injuries. Conclusion: The knee was most frequently injured which could be due to multi-planar loading. Turning or cutting movements typically involve motion in the frontal and transverse planes that may place the knee at greater risk of injury than movement in the sagittal plane alone. Sports medicine and support personnel should take into account the susceptibility of the knee to injury when designing training and injury prevention programmes given the large number of change of direction movements during badminton.

Title: Physical Activity and Gastrointestinal Tumors: Primary and Tertiary Preventive Effects and Underlying Biological Mechanisms

Abstract: Gastrointestinal tumors are frequent tumors worldwide. The impact of physical activity over the cancer continuum is, thus, of high relevance. This manuscript will give an overview on the current evidence for both, the more public health oriented view on possible reductions of cancer risks and mortality, mostly derived from large epidemiological studies, as well as the more clinical view on the effects of exercise and physical activity in cancer patients on cancer progression and side-effects of the disease and/or the cancer treatment. The latter studies are either observational or (randomized) clinical trials. The focus will be on gastrointestinal tumors, covering gastric, colon, rectal, pancreatic, liver, and gallbladder cancer. Besides colon cancers which have been investigated extensively at least with regard to cancer risk reductions through physical activity, most of these cancers have only been studied in recent years. Especially for tertiary prevention there is scarcity of studies. Besides summarizing the current evidence, including the knowledge on potential biological mechanisms, an outlook on future perspectives will be given.
