The study aimed to investigate the effect of combined balance and plyometric training on dynamic quickness performance elite badminton athletes. Sixteen male players volunteered participate were randomly assigned a balance-plyometric group (PB: n = 8) (PT: 8). PB performed with three times week over 6 weeks (40 min plyometrics 20 training); while PT undertook only for same period (3–4 sets × 8–12 reps each exercise). Both groups given technical (badminton techniques days week). stability...

During pregnancy, germline development is vital for maintaining the continuation of species. Recent studies have shown increased pregnancy risks in COVID-19 patients at perinatal stage. However, potential consequence infection reproductive quality developing fetuses remains unclear. Here, we analyze transcriptome and DNA methylome fetal following maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We find that early gestational age, a critical period human...

Embryos, originating from fertilized eggs, undergo continuous cell division and differentiation, accompanied by dramatic changes in transcription, translation, metabolism. Chromatin regulators, including transcription factors (TFs), play indispensable roles regulating these processes. Recently, the trophoblast regulator TFAP2C was identified as crucial initiating early fate decisions. However, Tfap2c transcripts persist both inner mass trophectoderm of blastocysts, prompting inquiry into...

Short-term (5 min) heart rate variability (HRV) analysis is widely used in assessing autonomic nervous system activity during exercise. While shortening the HRV measurement duration can help improve its application efficiency, accuracy needs to be verified. This study investigated agreement between ultra-short-term (UST) (3 or 4 and standard 5 min explored optimal recording under resting post-exercise conditions.

Purpose : To examine the acute effects of forehand drive (FD) preconditioning with or without blood-flow restriction (BFR) on subsequent performance and muscle recruitment in tennis. Methods On separate visits, 12 well-trained tennis players participated 4 randomized trials. Each visit included pretests (maximal muscle-activation capacity FD performance), a phase, posttests after 5 minutes rest (ie, similar to pretests). The phase involved sets 10 maximal-effort exercises, performed either...
