Muscle Activity During Unilateral vs. Bilateral Battle Rope Exercises.
2015
High training intensity is important for efficient strength gains. Although battle rope training is metabolically demanding, no studies have quantified intensity of muscle activity during this type of training. This study analyzes muscle activity during unilateral alternating waves vs. bilateral waves of battle rope training. Twenty-one volunteers participated in a repeated-measures study on 2 different occasions. Surface electromyographic signals were recorded from the anterior deltoid (AD), external oblique (OBLIQ), lumbar erector spinae (LUMB), and gluteus medius (GM) during bilateral waves and unilateral waves and were normalized to the maximum voluntary isometric contraction (MVIC).

Calcestruzzo autocompattante siciliano: un'esperienza con il filler vulcanico dell'Etna
2009
Self compacting concrete is one of the last developments in the technology of concrete, being studied and improved from the first '70es. Its production is connected with the use of fillers, most of which coming from iron metallurgy, scarsely present on Sicilian territory. So, the aim of the risearch was to realize self compacting concrete using exclusively local filler, particularly the Etna ashes with a strong pozzolanic connotation, pointing out the use of useless at the moment natural resource. The study relates to the verification of the more appropriate mix-designs and the tests on compressive strength of specimens to early curing and after 28 days. Different characterization tests wer…
