Twenty-nine untrained men were randomly allocated into three gro...

Low-intensity aerobic training combined with blood flow restriction (LI + BFR) has resulted in increases in aerobic and neuromuscular capacities in untrained individuals. This strategy may help cyclists incapable of training with high intensity bouts or during a rehabilitation program. However, there is a lack of evidence about the use of LI + BFR...

The effects of plyometric training on middle- and long-distance running performances are well established. However, its influence on pacing behavior is still unclear.

Typically, the one-repetition maximum test is used to identify the peak power output (optimal load) for the weightlifting derivatives without the catch phase (WOCP) (e.g., hang high pull, mid-thigh clean pull, and jump shrug). However, given the disadvantages of the regular one-repetition maximum test as the high time-consuming and the use of more...

We sought to determine if early increases in cross‐sectional area (CSA) of different muscles composing the quadriceps with low‐load resistance training with blood flow restriction (LL‐BFR) were mainly driven by muscle hypertrophy or by edema‐induced swelling. We also compared these changes to those promoted by high‐load resistance training (HL‐RT)....

Introduction: The myonuclear domain theory postulates that myonuclei are added to muscle fibres when increases in fibre cross-sectional area (i.e. hypertrophy) are ≥26%. However, recent studies have reported increased myonuclear content with lower levels (e.g. 12%) of muscle fibre hypertrophy. Purpose: To determine whether a muscle fibre hypertr...

Commentaries on Viewpoint: Resistance training and exercise tolerance during high-intensity exercise: moving beyond just running economy and muscle strength

Jump performance is considered an important factor in many sports. Thus, strategies such as weightlifting (WL) exercises, traditional resistance training (TRT) and plyometric training (PT) are effective at improving jump performance. However, it is not entirely clear which of these strategies can enable greater improvements on jump height. Thus, th...

This study investigated the effects of non-periodized (NP), traditional periodization (TP) and daily undulating (UP) regimens on muscle strength and hypertrophy in untrained individuals. Thirty-three recreationally active males were randomly divided into four groups: NP: n = 8; TP: n = 9; UP: n = 8 and control group (C): n = 8. Experimental groups...

Resisted sprint training consists of performing overloaded sprints, which may produce greater effects than traditional sprint training. We compared a resisted sprint training with overload control versus an unresisted sprint training program on performance in soccer players. Eighteen elite athletes were randomly assigned to resisted (RST) or unresi...

Satellite cells (SC) are associated with skeletal muscle remodelling after muscle damage and/or extensive hypertrophy resulting from resistance training (RT). We recently reported that early increases in muscle protein synthesis (MPS) during RT appear to be directed toward muscle damage repair, but MPS contributes to hypertrophy with progressive mu...

Introduction: We investigated differences in metabolic stress (lactate) and muscle activation (electromyography) when high load exercise is compared to a condition where blood flow restriction (BFR) is applied during the exercise or during the rest interval. Methods: Twelve participants performed high load resistance exercise with BFR during the...

The objectives of this study were to test if 12 weeks of progressive resistance training (RT) improves sleep quality and muscle strength in subjects with moderate Parkinson's disease (PD) and if sleep quality values of subjects with moderate PD are closer to those of age-matched healthy controls (HC) at post-training. This was a randomized controll...

Objectives The primary objective of this meta-analysis was to compare countermovement jump (CMJ) performance in studies that reported the highest value as opposed to average value for the purposes of monitoring neuromuscular status (i.e. fatigue and supercompensation). The secondary aim was to determine the sensitivity of the dependent variables....

The combination of strength (ST) and plyometric training (PT) has been shown to be effective for improving sport specific performance. However, there is no consensus about the most effective way to combine these methods in the same training session, in order to produce greater improvements in neuromuscular performance of soccer players. Thus, the p...

Key points: Skeletal muscle hypertrophy is one of the main outcomes from resistance training (RT), but how it is modulated throughout training is still unknown. We show that changes in myofibrillar protein synthesis (MyoPS) after an initial resistance exercise (RE) bout in the first week of RT (T1) were greater than those seen post-RE at the third...

The effects of an enforced fast-start on long distance performance are controversial and seem to depend on the athlete's capacity to delay and tolerate metabolic disruption. The aim of this study was to investigate the effects of an enforced fast-start on 10-km running performance and the influence of the some physiological and performance variable...

Purpose: To determine the influence of different cuff widths on muscle size and strength, and also investigate whether a wider cuff would result in less adaptation compared to a narrow cuff when inflated to the same relative pressure (80% arterial occlusion pressure). Methods: Eleven physically active males had their arms randomly divided into t...

The jump squat is one of the exercises most frequently used to improve lower body power production, which influences sports performance. However, the traditional determination of the specific workload at which power production is maximized (i.e., optimum power load) is time-consuming and requires one-repetition maximum tests. Therefore, the aim of...

We compared the effects of different protocols of blood-flow restriction training (BFRT) with different occlusion pressures and/or exercise intensities on muscle mass and strength. We also compared BFRT protocols with conventional high-intensity resistance training (RT). Twenty-six subjects had each leg allocated to two of five protocols. BFRT prot...

It has been proposed that skeletal muscle shows signs of resistance training (RT)-induced muscle hypertrophy much earlier (i.e., ~3-4 weeks of RT) than previously thought. We determined if early increases in whole muscle cross-sectional area (CSA) during a period of RT were concomitant with edematous muscle swelling and thus not completely attribut...

Running economy (RE) has an important role on middle and long distance running performance. Therefore, different strategies have been proposed to improve RE, as well as strength and power training. However, the results observed are still controversial. Thus, the aim of this review was to verify the effects of strength and power training regimens on...

Tensiomyography has been suggested as an indirect marker of muscle stiffness, which is associated with strength/power performance. Therefore, it is reasonable to suggest that tensiomyography parameters could be associated with power-related motor tasks. The purpose of this study was to investigate the association between tensiomyography parameters...
