Summary: The study found that both LL-BFR and HL training resulted in comparable changes in patellar tendon stiffness, with no significant differences between the two groups. Increases in tendon cross-sectional area were also similar in both HL and LL-BFR. Muscle mass and strength increased significantly in both groups, with slightly higher changes in knee extension 1RM seen in LL-BFR.

Summary: The study found that while muscle hypertrophy improvements seem to be load independent, increases in muscle strength are superior in high-load RT programs. Untrained participants exhibit greater muscle hypertrophy, whereas undertaking more RT sessions provides superior gains in those with previous training experience.

Summary: High-frequency BFR training can generate significant neuromuscular adaptations, but strength declines and muscle fiber atrophy were reported in resistance training to failure. There is a lack of studies comparing low-frequency and high-frequency in short-term BFR training. Comparisons between resistance exercises of similar intensities are also lacking, limiting conclusions on the specific effects of proximity to failure or BFR.

Summary: Objectives: This study aimed to investigate the impact of training one arm with a high load on the muscle size and strength of the opposing arm training with a low load. The results showed that high load training on one arm led to changes in strength of the opposing arm, but only the directly trained arms showed changes in muscle thickness.

Summary: We compared the changes in strength and muscle mass between stronger and weaker older women in response to resistance training. The study found that both groups showed similar gains in muscle mass and upper-limb strength, but weaker women experienced greater improvements in lower-limb strength. This suggests that older women, regardless of their initial strength levels, can benefit from resistance training for muscle and strength gains.

Summary: The study investigated the effects of independently applying blood flow restriction training (BFRT) and electrical muscle stimulation (EMS), as well as combining the two methods, on muscle function. The results showed that combining BFRT and EMS for low-intensity squat training improved muscle strength of the lower limbs by promoting muscle hypertrophy and improving muscle activation.

Summary: The study showed that 12 weeks of passive static stretching training can increase joint range of motion, improve maximum passive resistive torque, and reduce muscle stiffness. However, there were no significant effects on muscle architecture and maximum force-generating capacity.

Summary: This study evaluated the effects of dynamic and static stretching performed before resistance training on muscle adaptations in untrained young men. The results showed that 80 seconds of either static or dynamic stretching did not induce any additional muscular adaptations to resistance training in untrained young men.

Summary: Resistance-based blood flow restriction training (BFRT) and heavy-load resistance training (HLRT) have similar effects on muscle strength and size, activating similar anabolic pathways. However, BFRT leads to minor muscle hypertrophy, suggesting that strength adaptation is primarily driven by neurological adaptation.

Summary: The aim of this study was to compare the effect of chronic concentric or eccentric training on position sense and joint reaction angle in young men. The results showed that both types of training significantly changed position sense, reaction angle, and exercise-induced muscle damage indices after the initial training session. There were no significant changes after the final training session. The changes in position sense and reaction angle were related to the magnitude of muscle damage, rather than the type of muscle contraction.

Summary: This study compared the effects of long-term vs. periodic inclusion of isometric strength training on strength and dynamic performances. The results showed that 24 consecutive weeks of isometric strength training resulted in greater improvements in sprint performance than the control group, but there was no significant difference in all measured variables with periodic inclusion of isometric strength training.

Summary: This study aimed to determine the variables associated with swimming velocity and understand the relationship between stroke frequency-stroke length combinations and propulsion in young sprint swimmers. The results showed that swimming velocity was influenced by anthropometric, kinematic, and kinetic factors, and optimal combinations of stroke frequency and stroke length differed between males and females. The findings also indicated that higher propulsion was not necessarily linked to higher swimming velocity achievement.

Summary: The aim of this study was to compare stroke kinematics between junior and senior elite male swimmers in the 50-m freestyle event, and to identify stroke frequency (SF)-stroke length (SL) combinations that affect swim speed for these swimmers. Data from 86 junior swimmers (2019) and 95 senior swimmers (2021) competing in the LEN Championships were analyzed using t-tests and three-way ANOVAs. The results showed that senior swimmers were significantly faster than juniors in the 50-m race, with speed differences being the largest in the S0-15 m section. Both junior and senior swimmers showed significant variations in stroke length and stroke frequency in each race section, and multiple SF-SL combinations for maximum swim speed were observed.

Summary: This study aimed to analyze stroke kinematics and speed-time relationship in female swimmers competing in the four 50 m events of the 2021 European Championships. The results showed significant differences in swimming speed across all race sections for all strokes. Other kinematic variables had divergent findings, but stroke frequency presented an overall tier effect. Curve fitting revealed a cubic relationship for all strokes and tiers. This data provides valuable insights for coaches regarding the strategy and performance trends in 50 m sprint events.

Summary: The aim of this study was to assess the interaction of kinematic, kinetic, and energetic variables as speed predictors in adolescent swimmers. The results showed that time, stroke frequency, active drag coefficient, lactate concentration, and critical speed were significant predictors of speed. The interaction of kinematic, kinetic, and energetic variables seems to be the main predictor of speed in adolescent swimmers.

Summary: This study aimed to compare swimming velocity in front-crawl using discrete variables and Statistical Parametric Mapping (SPM). The sample included 30 young male swimmers divided into three groups based on their age. Results showed significant differences in swimming velocity between groups using discrete variables. SPM analysis revealed significant differences in swimming velocity between certain phases of the stroke cycle. Coaches and researchers should consider using both measurement approaches, but SPM provides more accurate and sensitive results about the swimmers' stroke cycle.

Summary: Applying data-reduction techniques to football training load (TL) monitoring has become a hot topic. This study aimed to reduce the dimensionality of TL measures and identify the most representative measure for each principal component. A principal component analysis (PCA) was conducted, and five principal components were identified. The highest factors in each principal component were decelerations, sprint distance, average HR, chronological age, and maximal speed.

Summary: The aim of this study was to evaluate the impact of exercise order in multicomponent training (MCT) on the maximum voluntary contraction (MVC) of older women. Results showed that initiating MCT with aerobic training followed by resistance training is the most effective approach for improving muscle strength in older women. Significant increases in MVC were observed for knee extensors, knee flexors, elbow flexors, and hand grip strength.
