BACKGROUND AND OBJECTIVE: Muscle strength imbalance can be an important factor in hamstrings muscle strain. The main purpose of this study was to investigate the effects of downhill running on hamstrings/quadriceps torque (H/Qtorque) and the electromechanical delay (H/QEMD) ratios. METHODS: Fifteen active male individuals performed two maximal voluntary isometric contractions of the knee extensors and knee flex...
The current investigation aimed to find the difference between right and left lower limb strength of quadriceps and hamstring muscles and describe young futsal players’ explosive strength and anaerobic power. The study comprised 12 university male U-20 futsal players (74.5 ± 9.7 kg;173.2 ± 7.2 cm; 18.7 ± 1.2 yrs.). Isometric strength was measured using an isometric dynamometer, lower limb explosive strength was...
Profile of users of anabolic and nutritionalsupplements in practitioners of resistive training in Gurupi-TOThe study objective was comparingthe profile of user and not ASS users in RT practitioners in Gurupi-TO. In the survey, 56 volunteers of both genders with age superior of 18 years who practiced RT at least three months participated Six colleges and a public plaza were visited, and each one twice and people...
Lactate kinetics in exercise intensity corresponding to heart hate deflection point The anaerobic threshold (LAn) is a necessary predictor of aerobic capacity and it has been used as reference of intensity in the elaboration of training of long distances athletes and people interested in health benefits by exercise. This study been proposed to analyze the behavior of blood lactate during the efforts in correspo...
Effect of rest interval between sets on the volume of repetitions in the crescent pyramidal method The rest interval between multiple sets is a key-factor that determines the ability of maintaining the number of repetitions performed in subsequent sets. In this sense, the objective of the present study was to evaluate the effect of different rest intervals in a crescent pyramidal method on the volume of perform...
Effect of resistance training in people with diabetes mellitus The diabetes mellitus is characterized mainly by the absence or inadequacy of the hormone insulin, and its endogenous production stimulated by the exercise, contributing like this to a better control glycemic. The resistance training promote increase sensibility the insulin, muscular mass and cardiovascular benefits, demonstrating be like this impor...
The aim of the present study was to control the intensity of a local exercises program for elderly women using Borg scale. sixteen elderly women (65.5±3.6 years) were selected; they were enrolled in the Physical Education, Sports and Recreation Center of ESALQ-USP. The proposed training was developed in 24 sessions during 12 weeks. The volunteers were submitted to a planned, organized and segmented (in periods)...
