Epidemiology of children's swimming competence and water safety.

2022

IntroductionThe main purpose of this study was to investigate children's swimming competence in primary schools of districts in Vojvodina, Serbia.MethodsIncluded subjects were primary school students from first to eighth grade (N = 2,778; male = 1,454, female = 1,324; age = 10.73 ± 2.1 years). We used Swimming Competence Questionnaire to acquire and analyze their swimming experience, non-fatal aquatic events, and demographics. For the statistical analysis, logistic regression and hierarchical multiple regression were used to evaluate if the factors and SC and NFAE were associated. The analyses were carried out by using SPSS® software version 24.0 (SPSS, Inc., Chicago, Illinois, USA).Results…

Rapid Weight Loss Coupled with Sport-Specific Training Impairs Heart Rate Recovery in Greco-Roman Wrestlers

2022

Wrestling is a sport that can be classified with the use of alternating aerobic–anaerobic metabolism with moderate but high-impact energy expenditure. Heart rate recovery (HRR) is the difference between heart rate during exercise and a certain amount of time after the start of recovery. The goal of this study was to determine the difference in HRR between two phases: high-intensity sport-specific training (HISST) combined with rapid weight loss (RWL)—phase 1 (P1) and HISST only—phase 2 (P2). Ten national-level wrestlers were included in this study. All participants underwent HISST along with RWL procedures for P1. Seven days later, during P2, an identical training session …

Rapid Weight Loss Alters Handgrip Strength In Greco-Roman Wrestlers

Effects of rapid weight loss (RWL) on handgrip strength (HGS) in combat sports athletes are still quite indefinite. The aim of this study was to delineate the effect of RWL on HGS in Greco-Roman wrestlers. Handgrip strength was measured during three time points. Baseline measurement was carried out before the weight reduction. Second measurement was done after sport specific training combined together with RWL. Finally, third measurement was carried out after sport specific training alone. Results showed that HGS was significantly greater after a training combined with RWL procedure compared to only specific training for one hand. Findings of this study could potentially improve the trainin…
