of a dissertation at the University of Miami. Muscular endurance is a major neuromuscular factor affecting independence and fall probability in older persons. PURPOSE: To determine the effects of sustained-release beta-alanine supplementation alone or in combination with a resistance training program on muscular and daily activity-based performances in older adults. METHODS: Twenty-seven subjec...

Aim To investigate the effect of push-up training with a similar load of to 40% of 1- repetition maximumal (1RM) bench press on muscle hypertrophy and strength gain in men. Methods Eighteen male participants (age, 20.2 ± 0.73 years, range: 19-22 years, height: 169.8 ± 4.4 cm, weight: 64.5 ± 4.7 kg) were randomly assigned to one of two experimental groups: bench press at 40%1RM (bench-press gr...

The purpose of this study was to establish the one-repetition maximum (1RM) prediction equations of a biceps curl, bench press, and squat from the submaximal skeletal muscle strength of 4-10RM or 11-15RM in older adults. The first group of 109 participants aged 60-75 years was recruited to measure their 1RM, 4-10RM, and 11-15RM of the three exercises. The 1RM prediction equations were developed...

The effect of head positioning is often not accounted for when optimising performance in the back squat exercise. primary aim study was to identify most advantageous position peak power (PP), velocity (PV) and force (PF) A secondary favourable position. Twenty male rugby union players performed 1x3 repetitions at 75% one repetition maximum (1RM) determine their preferred pre-intervention positi...

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...

PURPOSE/OBJECTIVES To examine peak volume of oxygen consumption (VO2peak) changes after a high- or low-intensity exercise intervention. DESIGN Experimental trial comparing two randomized intervention groups with control. SETTING An exercise clinic at a university in Australia. SAMPLE 87 prostate cancer survivors (aged 47-80 years) and 72 breast cancer survivors (aged 34-76 years). METHO...

Aerobic training is included to cardiac rehabilitation programs together with resistance training. The effects of combined aerobic and performed in a same session different protocols on peak capacity (VO2peak) maximal dynamic strength (1RM: one repetition maximum) are not well known. We compared the effectiveness two for 12 weeks three times week stable Coronary Artery Disease (CAD) patients (n...

The study investigated the concurrent validity and reliability of load-velocity relationship to predict one-repetition maximum (1RM) power clean from knee (PCK), high pull (HPK), mid-thigh (MTCP). For each exercise, 12 participants performed two 1RM sessions tests measure barbell’s at 30, 45, 60, 75, 90% 1RM. velocity recorded load was used establish linear regression equation and, consequently...

The aim of this study was to investigate the acute effects of 16 different combinations to cause the postactivation potentiation (PAP) in elite young soccer players. Squat exercise in 4 different intensities (40%, 60%, 80%, and 100% one-repetition maximum [1RM]) was performed and its effects were evaluated in the performance of countermovement jump (CMJ), after 4 different recovery times (1, 3,...

The objective of this study was to investigate the validity of power measurement techniques utilizing various kinematic and kinetic devices during the jump squat (JS), squat (S) and power clean (PC). Ten Division I male athletes were assessed for power output across various intensities: 0, 12, 27, 42, 56, 71, and 85% of one repetition maximum strength (1RM) in the JS and S and 30, 40, 50, 60, 7...
