Physiological response on 1 RM bench press performance

A number of methods for determining upper body maximal strength are present. The 1-RM is defined as the maximum amount of resistance that can be performed for only 1 repetition and it has been shown to be reliable in various populations. Further, setting an intensity of resistance training based on a percentage of the 1-RM has been found to be effective for improving outcomes such as muscle strength, muscle power, and muscle hypertrophy. Little is known about the metabolic cost of 1RM evaluation and which is the optimal recovery time between sessions. We analyzed the physiological response during a standardized protocol of 1RM-Bench Press Test (1RM-BP). Fourteen healthy subjects (25,6±7,4 y…

MOLECULAR SIGNALLING RESPONSE TO SHORT DURATION HIGH INTENSITY/LOW VOLUME RESISTANCE TRAINING IN HUMAN SKELETAL MUSCLE.

Introduction Resistance training (RT) is one of the most important stimuli for muscle hypertrophy, but it may play also an important role on weight loss and fat acid (FA) oxidation increase. It has been largely demonstrated that RT affects anabolic signalling molecule phosphorylation but, considering the numerous variables of RT, the differences between training modalities has been till now poorly investigated. The aim of this study was to assess Akt, 4EBP1, S6 and AMPK, ACC signalling after a single bout of high-intensity resistance training (HIRT) and of traditional resistance training (TRT). Methods 12 healthy subjects performed in two different moments and with different legs HIRT and T…

EFFECT OF KETOGENIC DIET ON EXPLOSIVE STRENGTH PERFORMANCE IN ELITE ARTISTIC GYMNASTS

Introduction Despite the increasing use of low carbohydrates/ketogenic diets (KD) on weight control and management of metabolic syndrome (Westman et al., 2007) there are paucity of researches about effects of KD diets on sport performances (Phinney et al., 1983a, 1983b). KD diets maybe useful in sports with weight class divisions. The aim of our study was to investigate the influence of KD on explosive strength performance, specifically in elite artistic gymnasts. Methods 8 male subjects (age 20.9 +/- 5.5 yrs) were recruited. Several physical and performance tests (body composition analysis, hanging straight leg raise, ground push up, parallel bars push up, pull up, squat jump, countermovem…
