The aim of the study was to determine whether similar muscle strength and hypertrophy responses observed after either low-intensity resistance exercise associated with moderate blood flow restriction or high-intensity are changes in messenger RNA (mRNA) expression selected genes involved myostatin (MSTN) signaling.Twenty-nine physically active male subjects were divided into three groups: (20% one-repetition maximum (1RM)) training (LI) (n = 10), (LIR) (80% 1RM) (HI) 9). All groups underwent...

Skeletal muscle hypertrophy is one of the main outcomes from resistance training (RT), but how it modulated throughout still unknown. We show that changes in myofibrillar protein synthesis (MyoPS) after an initial exercise (RE) bout first week RT (T1) were greater than those seen post-RE at third (T2) and tenth (T3) RT, with values being similar T2 T3. Muscle damage (Z-band streaming) was highest during recovery T1, lower minimal When highest, so integrated MyoPS (at T1), neither related to...

High-intensity resistance training (HRT) has been recommended to offset age-related loss in muscle strength and mass. However, part of the elderly population is often unable exercise at high intensities. Alternatively, low-intensity with blood flow restriction (LRT-BFR) emerged. The purpose this study was compare effects LRT-BFR HRT on quadriceps mass elderly. Twenty-three individuals, 14 men 9 women (age, 64.04 ± 3.81 years; weight, 72.55 16.52 kg; height, 163 11 cm), undertook 12 weeks...

Among sport conditioning coaches, there is considerable discussion regarding the efficiency of training methods that improve lower-body power.

The jump squat is one of the exercises most frequently used to improve lower body power production, which influences sports performance. However, traditional determination specific workload at production maximized (i.e., optimum load) time-consuming and requires one-repetition maximum tests. Therefore, aim this study was verify whether elite athletes from different would produce mean propulsive values a narrow range velocities, resulting in similar heights. One hundred nine several...
