The purpose of this study was to (a) assess the usefulness of volume load (VL), session rate of perceived exertion (SRPE), RPE load (RPEL), and a modified RPEL (RPEL-2) to estimate internal load from resistance exercise (RE) and (b) further assess the interactions between SRPE, VL, and RE intensity. Twelve healthy men (25 ± 4 years) completed RE sessions at 55, 70, and 85 1 repetition maximum (...

[Purpose] The aim of the present study was to verify the rate of perceived exertion and feelings of pleasure/displeasure in elderly women, who did normally perform physical exercises, following eight weeks of strength training in a constant routine. [Subjects and Methods] Eleven sedentary women were subjected to anthropometric assessment. The maximum load (100%) for each used in this study was ...

OBJECTIVES This study compares the effect of five different training stimuli on sprinting ability and strength production. DESIGN Sixty physical education students were randomly assigned to five experimental groups: all types of training (A), full-squat (B), parallel-squat (C), loaded countermovement jumping (D) and plyometric training (E). Participants in each group trained three days a week...

BACKGROUND Although studies have demonstrated the occurrence of postexercise hypotension (PEH) in resistance exercises, there is still no consensus on an ideal protocol. OBJECTIVE To evaluate the effects of different rest intervals (RI) between resistance exercise (RE) sets on postexercise blood pressure (BP). METHODS Sixteen sedentary non-hypertensive young men performed three RE protocols...

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...

Introduction: Adipose tissue plays an important role in increasing systemic inflammation and exercise training result in modulating inflammation by decreasing adipose tissue. The present study aimed to investigate the effect of 12 weeks circuit resistance training with 40, 60 and 80 percent of one-repetition maximum (1RM) on the levels of IL-10, IL-1β and body fat percent in obese postmenopausa...

The occurrence of postresistance exercise hypotension (PEH) after resistance exercise remains unknown. This study examined blood pressure and heart rate (HR) responses to an acute bout of low- and high-intensity resistance exercise, matched for total work, in trained males. Sixteen resistance-trained males (23.1 ± 5.9 years) performed an acute bout of low- (40% of 1 repetition maximum [1RM]) an...

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...

OBJECTIVE The aim of this study was to assess sensitivity and specificity of surrogate physical ability tests as predictors of criterion firefighting task performance and to identify corresponding minimum muscular strength and endurance standards. METHODS Fifty-one (26 male; 25 female) participants completed three criterion tasks (ladder lift, ladder lower, ladder extension) and three corresp...

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...
