Ö ÖZ ZE ET T A Am ma aç ç: : Kafein, amatör ve profesyonel sporcular arasında en yaygın kullanılan ergojenik desteklerden biridir. İçerdiği kafein oranı bakımından en önemli kafein kaynaklarından biri kahvedir. Kafeinin atletik performansa etkileri kapsamlı olarak araştırılmasına rağmen adölesanlarda anaerobik performansa etkileriyle ilgili yeterli çalışma olmamakla birlikte çoğunlukla erkeklerde yapılmış olan mevcut araştırmaların sonuçları da kesin değildir. Bu araştırmanın amacı, düşük doz kahve tüketiminin adölesan kız hentbolcularda anaerobik performansa akut etkilerini incelemektir. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bu araştırmaya kahve tüketim alışkanlığı olmayan 18 hentbol sporcusu kız (ortalama±standart sapma; yaş: 13,4±0,8 yıl; boy: 161±7 cm; kilo: 55±11,1 kg; vücut yağ yüzdesi: %24,9±4,45) gönüllü olarak katılmıştır. Testlerden yaklaşık on gün önce tüm katılımcılara test ve ölçümlerin birebir deneme ve tanıtımları yapılmıştır. Katılımcılar, kahve tüketimi sonrası (Kahve) ve kahve tüketmeden (Kontrol) olmak üzere bir hafta ara ile iki kez teste katılmışlardır. Katılımcılar düşük doz kafein içeren kahve (0,05 g/kg) tükettikten 60 dk sonra testlere geçilmiştir. B Bu ul lg gu ul la ar r: : Tüm katılımcılar 30-s Wingate anaerobik bisiklet testine katılmışlardır. Kahve tüketimi sonrası ve kontrol şartlarında yapılan test sonucu elde edilen maksimum güç (p=0,913), ortalama güç (p=0,201) ve yorgunluk indeksi (p=0,833) değerlerinde anlamlı fark olmadığı görülmüştür. S So on nu uç ç: Kahve ve kontrol ölçüm sonuçlarında maksimum güç, ortalama güç ve yorgunluk indeksi değerlerinin benzer olduğu söylenebilir. Analiz sonuçları, adölesan hentbolcu kızlarda düşük doz kafein içeren (~1,5-1,7 mg/kg) akut kahve tüketiminin maksimum güç, ortalama güç ve yorgunluk indeksine ergojenik etki ortaya çıkarmada yeterli olmadığını göstermiştir. Kahve tüketiminin adölesan ve çocuklarda atletik performansa etkileri ve bu etkilerin altında yatan mekanizmalarla ilgili doz-yanıt ilişkisi çerçevesinde yapılacak plasebo kontrollü yeni araştırmalara ihtiyaç olduğu söylenebilir.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Kafein; kahve; adölesan; anaerobik performans; ergojenik maddeler A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : Caffeine, is one of the most widely used ergogenic aid among amateur and professional athletes. Coffee is one of the most important caffeine source. Although the effects of caffeine on athletic performance have been investigated extensively. But the results of the current studies about the effects of coffee consumption on anaerobic performance are equivocal. Besides there are not enough studies the effects on adolescents and female athletes. Therefore, the aim of this study was to investigate the effects of acute coffee consumption with low-dose of caffeine on anaerobic performance in adolescent female handball players.

“…The amounts of daily intake strongly vary from 40 mg reported by adolescents in the UK up to 350 mg in Austria (5)(6)(7)(8)(9). However, due to a lack of empirical studies (10,11), the consequences of caffeine-intake on the developing neuronal and cardiovascular system are rather unclear. Accordingly, evidence-based limits for safe caffeine consumption in children and adolescents are missing up to date (10,11) and the American Academy of Pediatrics strongly recommends to eliminate the stimulant from the daily diet in this age group (12).…”

Background: Adolescents frequently consume caffeine with unknown consequences on sleep and circadian rhythms. In adults, the evidence indicates that caffeine acutely reduces homeostatic sleep pressure and delays the circadian timing system.Objective: Here, we investigated the acute effects of caffeine intake on the developing sleep-wake regulatory system of teenagers.Design: In a double-blind randomized crossover laboratory study, 18 teenagers (16.1 ± 1 years old, pubertal development scale [PDS]: 2.76 ± 0.35) ingested 80 mg caffeine (vs placebo) four hours prior to bedtime. Until bedtime, participants regularly filled in the Karolinska Sleepiness Scale and gave saliva samples to measure melatonin secretion. During nighttime, we quantified homeostatic sleep need by the electroencephalographically derived amount of slow wave sleep duration (SWS). After sleep, participants rated sleep quality by the Leeds Sleep Evaluation Questionnaire.Results: While participants felt less sleepy after caffeine vs. placebo (P=0.038), their ratings of sleep quality were not strongly affected by the treatment. However, objectively, SWS was on average reduced by ~20 min after caffeine vs. placebo (P=0.026). This caffeine-induced reduction was more pronounced in those individuals with more SWS under placebo (regression: P=0.042; standardized beta=0.622, P=0.011), even if controlling for habitual caffeine intake or pubertal stage (PDS). In melatonin onsets we observed both delays and advances in response to caffeine. This variance could partly be explained by differences in relative dose (i.e., mg caffeine/kg of bodyweight): the higher the relative dose, the more likely were delays (regression: P=0.01; standardized beta=0.592, P=0.01).Conclusions: In teenagers, evening caffeine intake of already 80 mg (i.e. ~8fl oz of common energy drinks) is sufficient to promote alertness at the costs of subsequent sleep. These costs might be more pronounced in adolescents with a higher need for SWS. Moreover, caffeine might disturb the circadian timing system, consequently hampering the balanced interplay of sleep-wake regulatory components.

ImportanceAdequate sleep duration is necessary for many aspects of child health, development, and well-being, yet sleep durations for children are declining, and effective strategies to increase sleep in healthy children remain to be elucidated.ObjectiveTo determine whether nonpharmaceutical interventions to improve sleep duration in healthy children are effective and to identify the key components of these interventions.Data SourcesCENTRAL, MEDLINE, Embase, PsycINFO, Web of Science Core collection, ClinicalTrials.gov, and WHO trials databases were searched from inception to November 15, 2021.Study SelectionRandomized clinical trials of interventions to improve sleep duration in healthy children were independently screened by 2 researchers. A total of 28 478 studies were identified.Data Extraction and SynthesisData were processed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guideline. Random-effects meta-analytic models were used to estimate pooled effect sizes.Main Outcomes and MeasuresDifference in sleep duration, measured in minutes.ResultsA total of 13 539 child participants from 45 randomized clinical trials were included. Of these, 6897 (50.9%) were in the intervention group and 6642 (49.1%) in the control group, and the mean age ranged from 18 months to 19 years. Pooled results indicate that sleep interventions were associated with 10.5 minutes (95% CI, 5.6-15.4) longer nocturnal sleep duration. There was substantial variation between trials. Sources of variation that were not associated with the study effect size included age group, whether the population was identified as having a sleep problem or being at a socioeconomic disadvantage (eg, coming from a low-income family or area), method of assessment of sleep duration (objective vs subjective), location of intervention delivery (home vs school), whether interventions were delivered in person or used parental involvement, whether behavioral theory was used, environmental change, or had greater or lower intensity. Interventions that included earlier bedtimes were associated with a 47-minute sleep extension (95% CI, 18.9-75.0; 3 trials) compared with remaining studies (7.4 minutes; 95% CI, 2.9-11.8; 42 trials) (P = .006 for group difference). Trials of shorter duration (6 months or less) had larger effects.Conclusions and RelevanceInterventions focused on earlier bedtimes may offer a simple, pragmatic, effective way to meaningfully increase sleep duration that could have important benefits for child health.
