Summary: This study examined the impact of 8 weeks of biweekly combined plyometric and short sprint training on the performance of youth male soccer players. The results showed that the experimental group demonstrated significant improvements in jump, sprint, change-of-direction ability, repeated shuttle sprint ability, and dynamic balance compared to the control group.

Summary: This meta-analysis examined the effects of complex training (CT) on sprint, jump, and change of direction (COD) ability among soccer players. Significant improvements were observed in the CT group, especially among players under 18 years old, training for more than 8 weeks, and professional athletes.

Summary: This systematic review examined protocols for measuring repeated sprint ability (RSA) and recommended standardized protocols. It was found that linear and change of direction (COD) RSA tests require different protocols, with COD tests resulting in longer sprint times compared to linear tests. The recommended protocol for linear RSA includes 6 x 30 m sprints with 15 seconds of active recovery, while the recommended protocol for COD RSA includes 6 x 30 m shuttle sprints with one change of direction and a 15-second active recovery.

Summary: This study aimed to investigate the immediate and 4-week boosting effects of 2-week, 6-session repeated-sprint training in hypoxia (RSH2-wk) on team-sport players' ability to perform repeated sprints (RSA) during a team-sport-specific intermittent exercise protocol (RSA(IEP)). The results showed that both 2-week and 5-week RSH regimens had similar effects on enhancing RSA during normal oxygen conditions, but the dose effect on RSA enhancement was minimal.

Summary: This study systematically reviewed the literature on the effect of exercise programs on the Repeated Sprint Ability (RSA) performance of soccer players. The results showed that a variety of programs can improve the performance of soccer players by causing trivial-to-large improvements. Interventional exercises that include stimuli related to repeated sprint ability are more effective.

Summary: Overall, plyometric jump training has a positive impact on athletes' repeated sprint ability, with improvements seen in best and mean sprint performance. However, there was no significant effect on fatigue resistance. The methodological quality of the included studies was moderate to high, and no injuries or adverse events were reported in any of the studies.

Summary: This study found that change of direction deficit (CODD) can provide a more accurate assessment of an athlete's change of direction (COD) ability, while change of direction total time (CODTT) is more correlated with linear sprint time. CODD for 180 degrees COD has a higher predictive value for CODTT.

Summary: Team sport athletes commonly perform repeated short-duration sprints with brief recovery periods. The physiological limiters of repeated-sprint ability include decreased force production capacity, insufficient energy supply, and metabolite accumulation. Training with blood flow restriction may improve these limiting factors and enhance repeated-sprint ability.

Summary: This study evaluated the effects of repeated sprint training in hypoxia on aerobic performance, repeated sprint ability, and muscle oxygenation in Rugby Sevens. The results showed that adding hypoxic training to standard training had minimal benefits in improving aerobic performance and resistance to fatigue, possibly due to enhanced muscle deoxygenation and increased levels of HIF-1 alpha and VEGF.

Summary: This study aimed to explore the relationships between field-based strength assessments and sprint and change of direction (COD) performance in male academy footballers. Findings indicate that scaled strength and imbalance, controlled for age, are associated with running ability, with significant effects from age, CMJ impulse, Nordic hamstring strength (NHS), and hip adductor (ADD) strength. Additionally, factors such as age and CMJ impulse were consistently featured in sprint and COD models, with hip adductor strength emerging as significant for specific sprint distances.

Summary: Multidirectional jumping and repeated sprint ability are crucial factors in basketball performance. This study aimed to investigate the effects of basketball-specific combined training programs compared to plyometric training on neuromuscular performance and body balance adaptations. The results showed that the combined drop jump and multidirectional repeated sprint training program led to significant improvements in neuromuscular performance, body balance, and change of direction ability in professional basketball players.

Summary: Repeated sprint ability (RSA) is more closely related to match performance outcomes than single-sprint performance, but the kinetic determinants in youth athletes remain poorly understood. The mechanical efficiency of force application (D-RF) was found to be the primary predictor of both single and repeated sprint performance in adolescents. Training programs targeting RSA should include technique and skill acquisition components.

Summary: This study aimed to determine the maximum relative load of the half-squat exercise that can be used in the jump squat exercise, and to examine if this reference value varies in subjects with different strength levels. Through testing 186 elite athletes, a relative strength value was identified to serve as a reference for the 1RM in the JS exercise.

Summary: Strength training induces a shift in myosin heavy chain composition from IIX to IIA by influencing CaMKII and SLN. The amount of fatigue allowed in each set critically determines muscle phenotype changes through its impact on CaMKII and SLN responses. Lower intra-set fatigue attenuates the IIX-to-IIA MHC shift.

Summary: All three resistance training programs led to significant improvements in muscle strength and endurance, with the 10% velocity loss group showing greater gains in vertical jump and sprint performance. This suggests that the magnitude of velocity loss in each exercise set can significantly influence training adaptations.

Summary: This study aimed to analyze the load-velocity relationship in female breast cancer survivors during bilateral leg-press exercises, comparing mean velocity (MV) and peak velocity (PV), and examining the accuracy of linear (LA) versus polynomial (PA) adjustment in predicting velocities associated with each %1RM. The results suggest that MV is the most suitable velocity variable for prescribing relative load during resistance training and that PA provides better accuracy in predicting velocities associated with each %1RM.

Summary: The study found a significant negative relationship between training load values and weekly CMJ, initial CMJ of the following week, and CMJ height loss, as well as a significant positive relationship between training load values and initial CMJ of the next consecutive session when LI values were <8. However, from values =8, the relationship turned into a significant negative one.

Summary: This study analyzed the effects of isolated endurance training and concurrent training on strength and endurance running performance. The results showed that the concurrent training group achieved greater strength gains, while the isolated endurance training group showed more significant improvements in endurance. Therefore, moderate velocity loss thresholds in resistance training during concurrent training may be an effective strategy for enhancing strength and endurance development simultaneously.
