Abstract

The present study investigated the relationship between punching acceleration and selected strength and power variables in nineteen professional karate athletes from the Brazilian National Team (9 men and 10 women; age: 23 ± 3 years; height: 1.71 ±0.09 m and body mass: 67.34 ± 13.44 kg). Punching acceleration was assessed under four different conditions in a randomized order: 1) fixed distance aiming to attain maximum speed (FS); 2) fixed distance aiming to attain maximum impact (FI); 3) self-selected distance aiming to attain maximum speed (SSS) and 4) self-selected distance aiming to attain maximum impact (SSI). The selected strength and power variables were as follows: maximal dynamic strength in bench press and squat-machine, squat and countermovement jump height, mean propulsive power in bench throw and jump squat, and mean propulsive velocity in jump squat with 40% of body mass. Upper and lower-body power and maximal dynamic strength variables were positively correlated to punch acceleration in all conditions. Multiple regression analysis also revealed predictive variables: relative mean propulsive power in squat jump (W/kg), and maximal dynamic strength (1RM) in both bench press and squat-machine exercises. An impact-oriented instruction and a self-selected distance to start the movement seem to be crucial to reach the highest acceleration during punching execution. This investigation, while demonstrating strong correlations between punching acceleration and strength-power variables, also provides important information for coaches, especially for designing better training strategies to improve punching speed.

Lateralidade no MMA

Lateralidade no MMA. Não deu diferença, mas como os autores tinham uma ideia fixa, concluíram o que queriam...Se é para fazer isso, nem roda a estatística...

Abstract

Performers with a left-orientation have a greater likelihood of obtaining elite levels of performance in many interactive sports. This study examined whether combat stance orientation was related to skill and success in Mixed Martial Arts fighters. Data were extracted for 1468 mixed martial artists from a reliable and valid online data source. Measures included fighting stance, win percentage and an ordinal measure of skill based on number of fights. The overall analysis revealed that the fraction of fighters using a southpaw stance was greater than the fraction of left-handers in the general population, but the relationship between stance and hand-preference is not well-understood. Furthermore, t-tests found no statistically significant relationship between laterality and winning percentage, although there was a significant difference between stances for number of fights. Southpaw fighters had a greater number of fights than those using an orthodox stance. These results contribute to an expanding database on the influence of laterality on sport performance and a relatively limited database on variables associated with success in mixed martial arts.

Recebi o convite para fazer um curso de mestrado e/ou doutorado

Deem uma olhada na propaganda e nos erros de digitação. Ainda bem que o curso não é na área de Português, não é? Afinal, quem precisa escrever direito nos dias de hoje...

De quebra, segue o link de um vídeo sobre como as pessoas não prestam atenção no que os outros falam. Deixei de pensar que eu que não sou claro quando explico algo...
