Between sportswear, mediators and the innovative daily brand through its applications (lactic acid concentration after warm-up / degree of body soup after warm-up / after warm-up PH modified) and the goal of the research is to create a sports suit that helps athletes to warm up quickly while maintaining physical fitness before starting the desired sporting activity ( The research is divided into the first axis, the problem, objectives, and assumptions of the research and methodology used in the previous research and studies related to the research and the second axis related to sportswear and the classification of functional smart fabrics, the third axis, the initial steps for applying the study sample specified in the research, which presents an analysis of the materials used, the special means for data collection , As well as an explanation of the thermal electronic circuit used in the research sample and an illustration of the form of the executed electronic sportswear design, as well as an illustration of specific exercises for traditional and innovative electronic clothes. that is innovative. Importance of research: - Creating sportswear that works with a thermal insulation system, which helps boxers to train, prepare and physiological before the match - Minimizing the player's energy consumption before the match. Methodology: The two researchers used the descriptive and analytical method. Main Findings: According to the research objectives and hypotheses, the following results were reached: Lactic acid concentration decreases after warming up with innovative warm-up clothes. - Increased muscle elasticity after wearing the innovative warm-up clothes. - Innovative warm-up clothes have thermal insulation compared to traditional warm-up clothes

Measured and estimated energy cost of constant and shuttle running in soccer players.

Players in team sports like soccer often make acceleration and deceleration movements, which are more energetically demanding than running at constant speed. The first aim of the present study was to estimate this difference in associated energy cost. To this end, we compared the actual energy cost of shuttle running to that of running at constant speed. In addition, since measuring oxygen consumption is not feasible during soccer, the study's second aim was to determine the validity of an indirect approach to estimate energy cost provided by di Prampero et al. (2005) using time-motion data obtained from a tracking system as input. Fourteen male amateur soccer players performed aerobic constant and continuous shuttle running at six different speeds (range = 7.5-10.0 km·h⁻¹) on artificial turf. Measured energy cost was compared to the energy cost estimated with di Prampero's (2005) equation using data from a local position measurement (LPM) system as input. As expected, measured energy cost was significantly higher (∼30%-50%) for shuttle running than for constant running (P < 0.001), and this difference increased with speed. For constant running, estimated energy cost was significantly higher (6%-11%) than measured energy cost, whereas for shuttle running, estimated energy cost was significantly lower (-13% to -16%) than measured energy cost. Shuttle running raised the player's energy cost of running compared to constant running at the same average speed. Although actual energy cost of constant running was significantly overestimated by di Prampero's approach using LPM data as input, actual energy cost of shuttle running was significantly underestimated.

Fun, Flow, and Fitness: Opinions for Making More Effective Active Videogames.

Despite active videogames' popularity and ability to increase a player's energy expenditure, research indicates their use sharply declines over time, which limits their utility in promoting physical activity. A frequent criticism is that a player's interest is quickly exhausted. At the preconference of the International Society of Behavioral Nutrition and Physical Activity 2014, a group of investigators and videogame developers gathered to share lessons learned from using serious videogames in health behavior change and offer insight to guide future efforts.

People Bouncing on Trampolines: Dramatic Energy Transfer, a Table-Top Demonstration, Complex Dynamics and a Zero Sum Game

Jumping on trampolines is a popular backyard recreation. In some trampoline games (e.g., “seat drop war”), when two people land on the trampoline with only a small time-lag, one person bounces much higher than the other, as if energy has been transferred from one to the other. First, we illustrate this energy-transfer in a table-top demonstration, consisting of two balls dropped onto a mini-trampoline, landing almost simultaneously, sometimes resulting in one ball bouncing much higher than the other. Next, using a simple mathematical model of two masses bouncing passively on a massless trampoline with no dissipation, we show that with specific landing conditions, it is possible to transfer all the kinetic energy of one mass to the other through the trampoline – in a single bounce. For human-like parameters, starting with equal energy, the energy transfer is maximal when one person lands approximately when the other is at the bottom of her bounce. The energy transfer persists even for very stiff surfaces. The energy-conservative mathematical model exhibits complex non-periodic long-term motions. To complement this passive bouncing model, we also performed a game-theoretic analysis, appropriate when both players are acting strategically to steal the other player's energy. We consider a zero-sum game in which each player's goal is to gain the other player's kinetic energy during a single bounce, by extending her leg during flight. For high initial energy and a symmetric situation, the best strategy for both subjects (minimax strategy and Nash equilibrium) is to use the shortest available leg length and not extend their legs. On the other hand, an asymmetry in initial heights allows the player with more energy to gain even more energy in the next bounce. Thus synchronous bouncing unstable is unstable both for passive bouncing and when leg lengths are controlled as in game-theoretic equilibria.

Controller, Hand, Screen

This paper tries to clarify the place of the handheld controller in computer game aesthetics. It starts from the premise that aesthetic form, perhaps the central category of modernist critical theory, is present in our play with computer games. The central argument is that controllers and our use of them are repressed in gameplay and that this repression facilitates a diversion of the player's energy that helps explain the compulsive nature of good games. Our sense of participation in events in game fiction is bought at the price of a loss of interest in our hands. The smooth integration of players into the rough, faltering world of gameplay is made possible by an excess of energy that passes from the unacknowledged tension in the hand into the imaginary relation we have with on-screen action.

Allocating energy in a first-to-n match

This paper models a decision where a player must allocate limited energy over a contest of uncertain length. The motivating example is a squash match where one of the players is not as fit as the other. Should a player's energy be concentrated in the early games of the match? Should it be spread evenly over all possible games? Or should it be conserved for the end of the match? We model this as a decision problem where, in each game, the decision‐maker must determine how much energy to expend. We assume that there are only a small number of discrete energy choices for each game and that the more energy the decision‐maker expends, the more likely he is to win that game. We solve for the optimal decision with dynamic programming. With only two possible energy choices for each game, we show that it does not matter how energy is expended. In the case where there are three or more energy choices, we show how to take advantage of the structure of the problem to determine the optimal sequence of decisions. As for practical advice, the model suggests that when the decision‐maker falls behind in a match, he ought to switch to a more conservative approach by dividing his remaining energy evenly among all the possible remaining games.
