Abstract
Bu çalışmanın temel amacı halter sporcularında çinko takviyesinin performans ölçütleri üzerine akut etkilerini araştırmak ve bu alandaki bilgi eksikliğini gidermektir. Elde edilen bulgular hem spor bilimi literatürüne katkıda bulunacak hem de sporcular için beslenme ve takviye stratejilerinin geliştirilmesine rehberlik edecektir. Normal dağılım gösteren verilerin analizinde Tekrarlı Ölçümler Testi kullanılmıştır. Çalışmanın anlamlılık düzeyi p<0,05 ve güven aralığı %95 olarak belirlenmiştir. Çalışmada elde edilen veriler değerlendirildiğinde, çinko takviyesi alan deney grubu haltercilerin hem ön test hem de son testte kontrol grubuna göre anlamlı bir fark bulunmuştur (p<0,05). Kuvvet sürekliliği parametresinde deney grubu haltercilerde kontrol grubuna göre ön testte anlamlı bir fark saptanmazken (p>0,05), son testte anlamlı bir fark bulunmuştur (p<0,05). Patlayıcı kuvvet parametresinde deney ve kontrol grupları arasında ön test ve son testte anlamlı bir fark saptanmamıştır (p>0,05). Bench press parametresinde deney grubu haltercilerde kontrol grubuna göre hem ön test hem de son testte anlamlı bir fark bulunmuştur (p<0,05). Squat parametresinde deney grubu haltercilerin ön testinde kontrol grubuna göre anlamlı bir fark saptanmazken (p>0,05), son testte anlamlı bir fark saptanmıştır (p<0,05). Sonuç olarak sporcularda çinko takviyesi kullanılmasının uygun olacağı ancak verilen değerler arasında olması gerektiği düşünülmektedir.

Abstract
The main purpose of this study is to investigate the acute effects of zinc supplementation on performance measures in weightlifting athletes and to eliminate the lack of information in this area. The findings obtained will both contribute to the sports science literature and guide the development of nutrition and supplementation strategies for athletes.. The data were analyzed for normality order with the Shapiro-Wilk test. Repeated Measures Test was used in the analysis of normally distributed data. The significance level of the study was taken as p<0.05 and the confidence interval was determined as 95%. Considering the data obtained in the study, a significant difference was found in both the pre-test and post-test of the experimental group weightlifters who received zinc supplements compared to the control group (p<0.05). In the force continuity parameter, no significant difference was detected in the pre-test (p>0.05) in the experimental group weightlifters compared to the control group, while a significant difference was detected in the post-test (p<0.05). In the explosive force parameter, no significant difference was detected between the experimental and control groups in the pre-test and post-test (p>0.05). In the bench press parameter, a significant difference was detected in both the pre-test and post-test of the experimental group weightlifters compared to the control group (p<0.05). In the squat parameter, no significant difference was detected in the pre-test of the experimental group weightlifters compared to the control group (p>0.05), while a significant difference was detected in the post-test (p<0.05).As a result, we think that zinc supplements should be used in athletes, but it is recommended to be within the given values threshold.
Ethical Statement
At the beginning of the study, participants were informed about the study protocol, program and tests to be performed before signing the informed consent form. The study protocol adhered to the principles of the Declaration of Helsinki and was approved by the Ethics Committee of Iğdır University (22.04.2024/ E-37077861-900-135462). Were conducted following the Helsinki Declaration.
