The Effect of Different Racket Weights on Accuracy in Forehand and Backhand Strokes in Recreational Tennis Players

Type: Research Article Published: 10-06-2026 Pages: 1-11

ABSTRACT

Purpose: This study investigates whether two racket masses affect forehand and backhand accuracy in recreational tennis players, focusing on the role of racket weight in stroke performance.

Methods: Twenty-nine recreational players completed forehand and backhand accuracy testing with two identical racket models differing in mass, following standardized warm-up and counterbalanced testing procedures.

Results: No statistically significant differences were observed between the lighter and heavier rackets for either forehand or backhand accuracy. Gender comparisons also did not reveal significant differences across tested conditions.

Conclusion: A 20 g difference in racket mass did not significantly influence stroke accuracy in recreational players. The findings suggest that motor consistency and technical skill development may be more important than minor changes in racket weight for amateur tennis performance.

Keywords: Tennis, racket mass, stroke accuracy, equipment selection, recreational tennis players

Personal Training Support and Motor Performance Test Outcomes in Trained Youth Athletes: A Cross-Sectional Study

Type: Research Article Published: 10-06-2026 Pages: 12-24

ABSTRACT

Purpose: This study examines whether personal training support influences talent screening and motor performance outcomes in trained youth athletes aged 14–19 years.

Methods: Sixty-one athletes were grouped according to whether they received at least six months of customized personal training or only routine club training. Flexibility, explosive power, sprint performance, and aerobic endurance were assessed using standardized field tests.

Results: No significant differences were found between athletes receiving personal training and those training only within club routines across the assessed motor performance variables.

Conclusion: In youth athletes already involved in structured club training, additional personal training was not associated with clearly superior motor test outcomes. Training quality, specificity, and long-term development planning may be more important than simply adding individualized supervision.

Keywords: Personal training, youth athletes, motor performance, physical fitness, talent identification, motor tests

Investigation of the Effects of Recreational Esports Players’ Nighttime Gaming Frequency on Chronotype and Sleep Quality

Type: Research Article Published: 10-06-2026 Pages: 25-35

ABSTRACT

Purpose: This study investigates relationships among nighttime gaming frequency, chronotype, and sleep quality in recreational esports players.

Methods: The study included university students with at least one year of esports involvement. Demographic information and nighttime gaming frequency were collected, while sleep quality and chronotype were assessed using standardized questionnaires.

Results: Overall sleep quality scores did not differ significantly according to nighttime gaming frequency. However, men who played more frequently at night showed a stronger tendency toward eveningness.

Conclusion: The findings indicate that chronotype is an important consideration in recreational esports contexts. Coaches and players may benefit from considering individual chronotype characteristics when planning gaming, training, and recovery routines.

Keywords: Esports, chronotype, MEQ, sleep quality, PSQI, video gaming
