background: the aim of this study is to verify the effects of the combined and classic training of different isometric rates of force development (rfd) parameters of legs. materials and methods: three groups of female athletes was tested: experimental group (n = 12), classically trained group (n = 11), and control group (n = 20) of athletes. the isometric “standing leg extension” and “ris...

Benito-Martínez E, Lara-Sánchez AJ, Berdejo-del-Fresno D, Martínez-López EJ. Effects of combined electrostimulation and plyometric training on vertical jump and speed tests. J. Hum. Sport Exerc. Vol. 6, No. 4, pp. 603-615, 2011. The aim of this study was to determine the performance evolution of a group of athletes after 8 weeks of training that combined electrostimulation (NM ES) and plyometri...

Numerous national associations and multiple reviews have documented the safety and efficacy of strength training for children and adolescents. The literature highlights the significant training-induced increases in strength associated with youth strength training. However, the effectiveness of youth strength training programs to improve power measures is not as clear. This discrepancy may be re...

The purpose of this study was to compare symptoms of exercise-induced muscle damage after an initial and repeated bout of plyometric exercise in men and boys. Ten boys (9-10 yr) and 10 men (20-29 yr) completed two bouts of eight sets of 10 plyometric jumps, 2 wk apart. Perceived soreness (0-10, visual analog scale), isometric strength of the quadriceps at six knee flexion angles, and countermov...

Background: Recent research has focused on the effects of different types strength training performance and body profile adolescent athletes. However, short-term plyometric jump rope athletic in basketball players are a matter curiosity. Objectives: The aim this study was to examine players. Methods: Twenty-two aged 13 - 15 were randomly divided into two groups as (n = 11) group 11). All partic...

In recent work, we proposed the all-pass t rans form (APT) as the basis of a speaker adaptation scheme intended for use with a large vocabulary speech recognition system. It was shown that APT-based adaptation reduces to a linear transformation of cepstral means, much like the better known maximum likelihood linear regression (MLLR). Due to this linearity, APT-based adaptation can be used in co...

BACKGROUND In the past, plyometric training (PT) has been predominantly performed on stable surfaces. The purpose of this pilot study was to examine effects of a 7-week lower body PT on stable vs. unstable surfaces. This type of exercise condition may be denoted as metastable equilibrium. METHODS Thirty-three physically active male sport science students (age: 24.1 ± 3.8 years) were randomly ...
