    The purpose of this study was to determine the impact of a 30 min nap (N30) on the Running-Based Anaerobic Sprint Test (RAST) both during and after Ramadan. Ten physically active kickboxers (age: 21.20 +/- 1.61 years, height: 174.80 +/- 4.34 cm, body mass: 73.30 +/- 7.10 kg and body mass index (BMI): 24.00 +/- 2.21 kg/m(2)) voluntarily performed the RAST test after an N30 and in a no-nap condition (NN) during two experimental periods: the last ten days of Ramadan (DR) and similar to 3 weeks after Ramadan (AR). During each DR-NN, DR-N30, AR-NN and AR-N30 protocol, kickboxers performed RAST performance. A statistically significant difference was found between Ramadan periods (DR vs. AR) in terms of max power (W) (F = 80.93; p(1) < 0.001; eta(2)(p) = 0.89), minimum power (W) (F = 49.05; p(1) < 0.001; eta(2)(p) = 0.84), average power (W) (F = 83.79; p(1) < 0.001; eta(2)(p) = 0.90) and fatigue index (%) results (F = 11.25; p(1) = 0.008; eta(2)(p) = 0.55). In addition, the nap factor was statistically significant in terms of the max power (W) (F = 81.89; p(2) < 0.001; eta(2)(p) = 0.90), minimum power (W) (F = 80.37; p(2) < 0.001; eta(2)(p) = 0.89), average power (W) (F = 108.41; p(2) < 0.001; eta(2)(p) = 0.92) and fatigue index (%) results (F = 16.14; p(2) = 0.003; eta(2)(p) = 0.64). Taking a daytime nap benefits subsequent performance in RAST. The benefits of napping were greater after an N30 opportunity for DR and AR.

    (2023) Bayer, Ramazan; Nobari, Hadi; Eken, Özgür; Bayrakdaroğlu, Serdar; Koç, Hürmüz; Pardos, Elena Mainer; Yağın, Fatma Hilal
    Numerous variables can affect performance before the competition. Nevertheless, it could be a subject of curiosity to find out whether a warm-up strategy has a more positive effect on the power performance of kickboxers. The purpose of this study is to evaluate the effect of different specific warm-up protocols and time of day on optimum power performance in kickboxers. Ten volunteer males performed three different warm-up routines in random order. The warm-up protocols consisted of only 20 min for each group. The groups with low-intensity aerobic running (NSWU) and specific warm-ups (SWU-20m) performed 20-min protocols. The other group followed 10 minutes of jogging and 10 minutes of specific warm-up (SWU-10m). All groups followed the warm-up randomly at two different periods of the day (i.e. morning: 09:00-10:00 and evening: 16:00-17:00) on non-consecutive days. A statistically significant difference was found between the groups in terms of Mean Propulsion (W) (F=3.518; p2=0.036). There was a statistically significant difference in Mean propulsive Power (W) between NSWU and SWU-10m (p3= 0.0007) in addition there was also a statistically significant difference in SWU-10m and SWU-20m (p3= 0.0106) and, NSWU and SWU-20m (p3= 0.415) protocols. In conclusion, mean propulsion (W) performance showed diurnal variation, and performances of the kickboxers’ can be affected more positively in the evening hours, especially after SWU protocols.

    The effect of time of day on visual reaction time performance in boxers: evaluation in terms of chronotype
    (Frontiers Media Sa, 2025) Kurak, Kemal; Ilbak, Ismail; Stojanovic, Stefan; Bayer, Ramazan; Ilbak, Yunus Emre; Kasicki, Krzysztof; Ambrozy, Tadeusz
    Introduction Considering the impact of individual differences on athletes' performance, chronotype emerges as a crucial variable in training program design. Chronotype influences an individual's ability to achieve peak physical and cognitive performance at different times of the day based on their biological rhythms. While numerous studies have explored the relationship between chronotype and physical performance, its effect on reaction time performance remains insufficiently investigated. In sports, where reaction time is a key determinant-such as in boxing-understanding this relationship could contribute to the personalization of training programs. Therefore, the aim of this cross-sectional study was to examine how the visual reaction performance of active boxers varies at different times of the day based on their chronotypes. Methods Twenty-four active boxers participated in the study. Their chronotypes were determined using the Morningness-Eveningness Questionnaire, categorizing them as either morning type (M-type) or evening type (E-type). The participants were divided into two groups: M-type (n = 12) and E-type (n = 12). Each participant completed a visual reaction time (VRT) performance test at three different times of the day: morning (09:00 h), afternoon (13:00 h), and evening (17:00 h). Results The findings revealed a statistically significant group x time interaction effect on VRT performance (p < 0.01). M-type athletes showed a significant decline in VRT performance during the evening compared to the morning and afternoon. In contrast, E-type athletes demonstrated significantly better performance in the evening compared to the morning. Conclusions Boxers' visual reaction time performance varies throughout the day depending on their chronotype. These results suggest that coaches and exercise specialists should consider athletes' chronotypes when designing training programs focused on reaction time enhancement. To optimize performance, it is recommended that M-type athletes conduct such training sessions in the morning, while E-type athletes should train in the evening, when their reaction time performance tends to peak.

    The Effects of Different Stretching Techniques Used in Warm-Up on the Triggering of Post-Activation Performance Enhancement in Soccer Players
    (Mdpi, 2024) Kurak, Kemal; Ilbak, Ismail; Stojanovic, Stefan; Bayer, Ramazan; Purenovic-Ivanovic, Tijana; Palka, Tomasz; Ambrozy, Tadeusz
    The aim of this research was to investigate the effects of different stretching techniques used during warm-up exercises prior to post-activation performance enhancement (PAPE) on the explosive lower extremity strength performance of soccer players. This cross-sectional study involved the participation of 13 male soccer players with an average age of 22.38 +/- 1.75, body height of 174.38 +/- 3.94, and body mass of 72.30 +/- 4.13. To determine the participants' maximal strength performance, one repeated maximal strength (1-RM) squat exercise was applied. The PAPE protocol was then implemented with a squat exercise consisting of three repetitions at 80% of 1-RM. The warm-up protocols consisted of 5 min of cycling, followed by dynamic stretching, static stretching, or proprioceptive neuromuscular facilitation (PNF) stretching exercises. These protocols were applied on four different days with a 72 h interval. A vertical jump test was conducted to measure the participants' explosive strength performance. The research data were analyzed using IBM Statistics (SPSS version 26.0, Armonk, NY, USA) software. The findings of this study revealed statistically significant differences in vertical jump performance values after PAPE among participants based on the different stretching techniques used during warm-up (p = 0.00). In this context, the research concluded that dynamic stretching is the optimal stretching technique during warm-up exercises before PAPE to maximize its effects. On the other hand, static stretching was found to negatively affect performance by absorbing the PAPE effect.

    The efficacy of Air Alert plyometric training program on enhancing biomotor skills in adolescent basketball players
    (Lippincott Williams & Wilkins, 2025) Yalçın, Onur; Açak, Mahmut; Kurtoğlu, Ahmet; Eken, Özgür; Bayer, Ramazan; Aldhahi, Monira I.
    Background:Basketball is an important sport that utilizes a variety of biomotor skills. Diverse training programs are employed to enhance the biomotor attributes and elevate the performance levels of basketball players. Plyometric training (PT) is frequently used to improve athlete performance. However, different models of PT can yield varying effects on athletic performance.Methods:This study aimed to determine the impact of a PT program named Air Alert on athletes' biomotor skills. Twenty-four basketball players aged 15 to 16 years voluntarily participated in the study. The participants were randomly assigned to 2 groups: the Air Alert plyometric training group (AIR) (n = 12) and the plyometric training group (n = 12). The AIR was trained 3 days a week, while the plyometric training group was trained 2 days a week for 15 weeks. Pre- and posttest measurements of height (cm), body weight (kg), vertical jump, line agility, 20 m sprint, Illinois agility, repeated sprint, and flamingo balance tests were performed for all participants.Results:There were no significant differences in height (cm) (F = 1.035, P = .320, eta p2 = .045), weight (F = 1.735, P = .201, eta p2 = .073), and BMI measurements (F = 1.376, P = .253, eta p2 = .059) within and between groups. However, significant differences were observed between the groups in vertical jump (F = 14.343, P = .001, eta p2 = .395), line agility (F = 75.366, P = .000, eta p2 = .774), 20 m sprint (F = 93.001, P = .000, eta p2 = .809), balance (F = 59.513, P = .000, eta p2 = .730), Illinois agility test (F = 143.243, P = .000, eta p2 = .867), and repeated sprint test (F = 140.986, P = .000, eta p2 = .865).Conclusion:The results of this study indicate that the AIR program is more effective in enhancing the biomotor skills of basketball players than other plyometric training programs. Based on these results, it is recommended that coaches who aim to develop training strategies to enhance athletic performance should consider incorporating an Air Alert program.
