Enhancing high-intensity actions during a basketball game after a strength training program with random recovery times between sets

To examine the effects of a strength training program with random recovery times between sets in consideration of several physical parameters, high-intensity actions (HIA), and spatial exploration index during a simulated basketball game. Twenty male basketball players (age: 19.45 ± 4.36 years) were assigned randomly, either to strength training group (n = 10), or a control group (n = 10). The strength training included: parallel back squat and bench press exercises, twice a week for the duration of 10 weeks, with two blocks of 5 sets × 5 repetitions interspersed with variable passive recovery (range = 15–35 sec.) between sets, and constant passive recovery (3-min) between blocks with the load that maximized propulsive power output. The pre- and post-test assessments included jumping (bilateral and unilateral), change-of-direction, straight sprinting, and a 5-on-5 full-court situation. The external training load was assessed using the local positioning system, and the internal load was recorded with the use of individual heart rate monitors. A significant interaction effect (group x time) was observed on countermovement jump (CMJ), unilateral right hops, high-intensity accelerations and decelerations, and peak accelerations and decelerations in the 5-on-5 full-court situation. Relative improvements observed and recorded in the training group on unilateral right hops, accelerations, and decelerations were correlated. Similar results were observed on 0–25m sprints, high-intensity decelerations, peak accelerations, and decelerations. Strength training paired with random recovery times enhanced physical and game-related aspects in the observed basketball players

Rotational flywheel training in youth female team sport athletes: could inter-repetition movement variability be beneficial?

Background: The aim of this study was to analyse the effects of an inter-repetition variable rotational flywheel training program (Variable) over standard rotational flywheel training (Standard). Methods: Twenty-four youth female team-sports players were randomly assigned to both training groups (Variable, n = 12; Standard, n = 12), which consisted of 1 set of 3 rotational flywheel exercises x 10-12 repetitions, biweekly for a period of 6-weeks. The participants included in Variable group were instructed to perform the movement randomly in one of the three directions (0º, 45º right, and 45º left). Measurements included reactive strength, jumping, change of direction, and sprinting tests; patellar tendon condition was also assessed. Results: Substantial improvements were found in vertical jump with left leg (16.9%), lateral jump with right leg (13.6%), and patellar condition in left leg (4.1%) for Standard group, but also in reactive strength index in right leg landing (33.9%), vertical jump with right (10.1%) and left leg (12.0%) for Variable group. A significant interaction effect (group x time) was observed on patellar condition in right leg (F = 10.02, p < 0.01, η 2 = 0.37), favoring Variable group. Conclusions: Rotational flywheel training programs were beneficial for youth-female team-sports athletes, although the movement variability may play a key role to develop different and specific physical adaptations

The concept of territorial frugality, how to identify, quantify and apply: The study of Lisbon Metropolitan Area

“In behavioral science, frugality has been defined as the tendency to acquire goods and services in a contained manner, and use of the economic goods, resources and services themselves, to achieve a long-term goal” [1] The present project intends to study the introduction of the concept of territorial frugality, characterizing its applicability to the territory, specifically to the urban space, as a tool in the parsimonious use of available resources, as well as studying its measurement through a mixed methodology. An interventionist, either using the opinion of a group of experts, using the DELPHI technique, as well as the establishment of conceptual models or using other methods in order to identify, select and define the applicability of indicators that allow the evaluation or establishment of parameters correlated with the concept of frugality, within the scope of spatial planning and urbanism, within the case of Lisbon Metropolitan Area.info:eu-repo/semantics/publishedVersio
