PURPOSE The purpose of the current investigation was to determine the relationship between relative net vertical impulse (net vertical impulse (VI)) and jump height in the jump squat (JS) going to different squat depths and utilizing various loads. METHODS Ten males with two years of jumping experience participated in this investigation (Age: 21.8 ± 1.9 y; Height: 176.9 ± 5.2 cm; Body Mass: 7...

INTRODUCTION Maximal strength is often estimated using the force-endurance relationship, where tables or formula are used to predict one repetition maximum (1RM) or other loads (e.g. 3RM loads). For some populations (for example the frail or very young) such a procedure may not be appropriate and the accuracy of these methods depends on several parameters such as the number of repetitions, type...

This study aimed to analyze between-shoulder kinematics symmetry at different load intensities considering full range of movement (ROM), mean and maximum velocities (VMEAN, VMAX), accelerations (AMEAN, AMAX) shoulders during phases 2 (characterized by positive acceleration negative velocity, eccentric) 3 concentric) bench press exercise (BP); as well compare unilateral variables between the int...

Speed strength performances are heavily dependent on maximum strength. However, various testing methods determined inconsistent relationships between absolute and relative sprint jump performances. The aim of the study was to calculate one tailed correlation coefficients both One-Repetition Maximum (1RM) 1RM in relation body mass (1RM/BM) parallel squats different (squat countermovement jump) (...

The purpose of the present study was to examine the influence of muscle group location and gender on the reliability of assessing the one-repetition maximum (1RM) test. Thirty healthy males (n = 15) and females (n = 15) who experienced at least 3 months of continuous resistance training during the last 2 years aged 18-35 years volunteered to participate in the study. The 1RM for the biceps curl...

We examined whether high-speed power training (HSPT) improved muscle performance and braking speed using a driving simulator. 72 older adults (22 m, 50 f; age = 70.6 ± 7.3 yrs) were randomized to HSPT at 40% one-repetition maximum (1RM) (HSPT: n = 25; 3 sets of 12-14 repetitions), slow-speed strength training at 80%1RM (SSST: n = 25; 3 sets of 8-10 repetitions), or control (CON: n = 22; stretch...

Background: Paralympic powerlifting (PP) presents adaptations that the training tends to provide, mainly concerning mechanical variables. Objective: Our aim was analyze mechanical, dynamic and static indicators, at different intensities, on performance of paralympic athletes. Methods: 23 athletes PP, 11 national level (NL) 12 regional (RL) performed tests over a comprehensive range loads. The s...

Abstract Study aim : This study aimed to determine and compare the ‘optimum power load’ in hexagonal (HBDL) straight (SBDL) bar deadlift exercises. Material methods Fifteen novice strength-trained males performed three repetitions of HBDL SBDL at loads from 20–90% their one-repetition maximum (1RM). Peak power, average peak velocity, velocity were determined each repetition using a velocity-bas...

Previous research has demonstrated the importance of isometric maximal strength (PF) and rate of force development (RFD) in a variety of athletic populations including track cyclists and track and field athletes. Among coaches and sports scientists there is a lack of agreement regarding how much strength is required for optimal performance in most sports. The purpose of this study was to examin...

BACKGROUND It has been suggested that strength training effects (i.e. neural or structural) vary, depending on the total repetitions performed and velocity loss in each training set. PURPOSE The aim of this study is to compare the effects of two training programmes (i.e. one with loads that maximise power output and individualised repetitions, and the other following traditional power trainin...
