Effects of Sparring Load on Reaction Speed and Punch Force During the Precompetition and Competition Periods in Boxing.
2017
Seven, male, national-level boxers (age, 20.3 ± 2.7 years; height, 1.80 ± 0.06 m; mass, 73.8 ± 11.1 kg) participated in this study to investigate the effects of sparring on reaction time and punch force of straight punches measured during the precompetition and competition periods. Heart rate and blood lactate concentrations were also monitored. Sparring load was chosen in accordance with the current rules: 3 × 3-minute bouts with 1-minute break in between. Reaction time of rear straight lengthened (p < 0.01) during the sparring load of the precompetition period after the third round (to 390 milliseconds) in comparison to the competition period (to 310 milliseconds). Reaction time of lead s…
Supervision by the state prerogatives of french sports federations
2013
French sports federations have developed without any state intervention. They had their own prerogatives to organize competitions in their respective sporting discipline. By virtue of their association status, they were entirely governed by private law. However, following a decision taken in 1974 by the Board of State confirming the existence of a public service delegated to the federal structure, the legislation gradually devote the principle of granting their prerogatives by the Ministry of Sports through two acts: the ministerial approval and delegation of public service. Since the issuance of these acts is synonymous powers recognized federations by state law and that the delegation lea…

Acute neuromuscular responses to short and long roundhouse kick striking paces in professional Muay Thai fighters.
2019
International audience; BACKGROUND: Muay Thai fighters strongly rely on the use of the roundhouse kick due to its effectiveness (i.e. power) and implications on the final score. Therefore, different striking tempos at full power are used during training as a method to enhance kicking power. However, the neuromuscular responses are unknown. Thus, the goal of this study was to investigate neuromuscular responses to a single bout of shorter (every second = H1) and longer (every 3s = H3) kick striking time intervals, measured with the countermovement jump (CMJ).METHODS: Nine professional Muay Thai fighters participated in this randomized, cross-over trial. CMJs were measured on force plates bef…
The De Giorgi measure and an obstacle problem related to minimal surfaces in metric spaces
2010
Abstract We study the existence of a set with minimal perimeter that separates two disjoint sets in a metric measure space equipped with a doubling measure and supporting a Poincare inequality. A measure constructed by De Giorgi is used to state a relaxed problem, whose solution coincides with the solution to the original problem for measure theoretically thick sets. Moreover, we study properties of the De Giorgi measure on metric measure spaces and show that it is comparable to the Hausdorff measure of codimension one. We also explore the relationship between the De Giorgi measure and the variational capacity of order one. The theory of functions of bounded variation on metric spaces is us…
DEVELOPING AND MEASURING ATTENTION IN BOXERS: MIXED COACHES’ EXPERTISE AND REACTION TIME MEASURES
2020
This study explored the problem of attention and its development in young boxers. A rapidly changing situation and a high level of traumatization in boxing are demanding the development of athletes’ attention. Focusing on technical or motivational training is among the reasons for underestimating the development of attentional skills. Study 1 involved seven expert coaches (males, mean age 45.4, mean working experience 20.3 years). The results revealed a relatively high assessment of the psychological component of training and a low agreement on the development of attentional skills. Coaches indicated that testing is the best measurement of attention. Study 2 focused on the measurement of re…
“Red wins”, “black wins” and “blue loses” effects are in the eye of beholder, but they are culturally universal: A cross-cultural analysis of the inf…
2014
Abstract Although many studies have demonstrated an influence of uniform colors on sports performance, there are still more questions than answers regarding this issue. In our study, participants from Poland (N = 147) and China (N = 143) watched a two-minute video of a semi-professional boxing match. The participants viewed six different versions of the same fight - the original was modified to change the colors of the boxers’ trunks (red vs. blue, blue vs. red, blue vs. black, black vs. blue, red vs. black, and black vs. red). We experimentally confirmed that “black wins” and “red wins” effects exist, but in a way that caused an erroneous perception of the number of blows landed by boxers …
