Water-saving techniques for restoring desertified lands: some lessons from the field
2022
Nature-based solutions can significantly contribute to restoration projects in areas affected by desertification processes, where they are necessary for reversing land degradation. Currently, one innovative solution is The Cocoon™, which has been designed as a new ecotechnology for improving seedling establishment. The Cocoon consists of a doughnut-shaped container made of recycled cardboard that provides water and shelter at least during the first year of a seedling, which is the most critical for plant establishment. To determine the effectiveness of this ecotechnology under different conditions, the Cocoon was tested on a variety of soils, climates, vegetation, and land uses. Six plantin…
Two-Leg Squat Jumps in Water: An Effective Alternative to Dry Land Jumps
2009
The current study was designed to quantify and compare the kinetic parameters of two-leg squat jumps carried out on dry land, in water and in water using area devices that increase drag force. Twelve junior female handball players who had been competing at national level for the previous two years volunteered to participate in the study. Intensity of the two-leg squat jump was examined using a force plate (9 253-B11, Kistler Instrument AG, Winterthur, Switzerland) in three different conditions: on dry land, in water and in water using devices. An ANOVA with repeated measurements (condition) was applied to establish differences between the three jumps. The results show that peak impact force…
Muscular Activity of the Posterior Deltoid During Swimming vs. Resistance Exercises on Water and Dry Land
2010
The purpose of this study was to compare muscular activity of the posterior deltoid muscle during three typical aquatic physical conditioning activities. This interpretative case study involved a 23-year-old elite swimmer and athlete. Muscular activity was measured with surface electromyography during swimming crawl at maximum speed, and also while performing horizontal shoulder abduction using elastic band and Hydro-Tone Bells resistance. During the maximum voluntary contraction, we observed what appeared to be meaningful differences between the percentage of muscular activation during the swimming activity and that observed during the elastic band and aquatic resistance exercises (18.72% …
Effects of aquatic and dry land resistance training devices on body composition and physical capacity in postmenopausal women.
2013
Effects of Aquatic and Dry Land Resistance Training Devices on Body Composition and Physical Capacity in Postmenopausal Women To determine the effects of a supervised strength training program on body composition and physical capacity of older women using three different devices: weight machines, elastic bands, and aquatic devices that increase drag forces (ADIDF). Four groups were formed: control group, weight machine group (WMG), elastic band group (EBG) and a group that used ADIDF (ADIDFG). Body composition and physical capacity were assessed before and after the intervention period. The ADIDFG showed improvements in fat mass (FM), fat-free mass of the left arm (FFM-LA) and right arm (FF…
