Impact of Combined Core Strength, Balance and Visual Skill Training on Selected Skill-Related Physical Fitness and Performance Variables of School-Level Badminton Players in Tirupathur District: A Quasi-Experimental Study
Researchers gave school-age badminton players in Tamil Nadu a 12-week programme combining core strength, balance, and visual (eye-tracking/coordination) training, then compared them with players doing their usual training. The trained group showed greater gains in agility, dynamic balance, explosive power, eye-hand coordination, and badminton skill performance than the control group.
VR/AR Immersive Training in Dragon and Lion Dance Teaching in Colleges and Universities
Researchers built a VR/AR immersive training system, paired with UWB/IMU motion tracking, to teach dragon and lion dance in universities and to measure team coordination that is normally hard to quantify. The experimental group's coordination efficiency scores on complex movement curves improved by 42.30%, with notable reductions in trajectory deviation and breakdowns in group formation, and tactile feedback was reported as a key factor.
Trajectories of 10 m Sprint Time and Countermovement Jump Height Relative to Peak Height Velocity in Male Youth Soccer Players.
Researchers tracked 20 academy soccer players (ages ~11-16) for 4-5 years, measuring 10 m sprint times and countermovement jump height and lining up the data against each boy's growth spurt (peak height velocity). Jump height improved fastest just after the growth spurt (about +3 cm per year), while sprint acceleration improved steadily (~0.04 s per year) with no spurt-related surge, and individual gains in jumping and sprinting were unrelated.
Assessing Sprint Mechanical Outputs Derived from LPS, Radar and Laser Technologies in Basketball.
Researchers had 22 elite youth basketball players run maximal 28 m indoor sprints while simultaneously measuring them with a Kinexon local positioning system (LPS), radar, and laser, then compared the sprint speed and acceleration values each produced. Radar and laser agreed closely on top speed, while LPS consistently read speed about 5-6% higher, and acceleration-related measures (A0 and Tau) differed most between systems; all three, however, were repeatable trial-to-trial.
Validity and Reliability of a 3-Point Load-Velocity Profile for Predicting Hex Bar Deadlift 1 Repetition Maximum.
Researchers had 19 trained lifters do both a traditional hex bar deadlift 1RM test and a quick submaximal test using three loads, measuring bar speed to estimate maximal strength. The estimate matched actual 1RM closely on average (explaining ~97.5% of variance) and the theoretical max load measure was very repeatable between sessions, but individual predictions could be off by up to about 15.7 kg, so the two methods aren't interchangeable.
Analysis of the Load-Velocity Relationship in the Full Squat Exercise in Female Soccer Players of Different Ages.
Researchers tested 85 female soccer players (senior, U18, U16) doing progressively heavier full squats to see how bar speed relates to the percentage of their one-rep max. Velocity predicted relative load very well (especially mean propulsive velocity and mean velocity, less so peak velocity), and the relationship was essentially the same regardless of age group.
Competition-level and positional differences in match running performance of Vietnamese professional soccer players: a GPS-based season analysis.
Researchers used 10 Hz GPS trackers to measure the running output of 160 Vietnamese professional footballers across 57 matches in the top two leagues over the 2024-2025 season, comparing competition levels and playing positions. Top-tier (V-League 1) players covered significantly more high-speed running and sprint distance and recorded higher top speeds, accelerations and decelerations, and running measures also differed significantly by position; the authors propose a composite performance score for profiling players.
Feasibility and preliminary agreement of a lower-volume, pool-based incremental swimming protocol in trained male university swimmers: a pilot study.
Researchers tested whether a shorter swim test (50-100-150-200 m) could stand in for the standard, much longer 7 x 200 m incremental step test in ten trained male university swimmers. The short test was practical to run and matched the long one reasonably well for swimming velocity and stroke-mechanics measures, but agreed poorly on completion time, peak heart rate, and lactate change, so it isn't a direct substitute.
Predicting 2,000-meter rowing ergometer performance with 7-stroke peak power, 20-Second, and 60-Second maximal effort tests in NCAA DI female rowers.
Researchers tested 40 NCAA Division I female rowers on three short all-out rowing ergometer efforts (a 7-stroke peak power test, a 20-second test, and a 60-second test) and compared the results to their 2,000-meter erg times. Average power in the 60-second test was the strongest single predictor of 2k time (R² = 0.611, r = -0.78), followed by the 20-second test (R² = 0.536), while the 7-stroke peak power test was the weakest (R² = 0.417).
The effects of velocity-based vs. percentage-based resistance training on sports performance in trained individuals: a systematic review and meta-analysis
Systematic review and meta-analysis comparing velocity-based against percentage-based resistance training for strength, jump, sprint, and change-of-direction performance.
Individualized responses to velocity-based versus percentage-based resistance training in combat sports athletes: the influence of baseline characteristics
Trial examining how athletes' baseline characteristics influence their individual responses to velocity-based versus percentage-based resistance training in combat sports.
