Physiological Responses of Elite Cheerleaders During Training and Simulated Competition Routines.

Purpose: Competitive cheerleading (cheersport) is a physically demanding sport; however, there is a lack of information regarding its acute physiological responses during training or competition in these athletes. Thus, this study aimed to investigate these responses during both training sessions and simulated cheerleading competition routines (full-outs) among elite cheersport athletes.

Methods: Six Coed and 10 All Girl elite cheerleaders were included in this study.

Distinct subtypes of post-transplant lymphoproliferative disorders: CHIP-like mutations in early lesions and substantial mutational differences between EBV-positive and EBV-negative diffuse large B-cell lymphomas.

Post-transplant lymphoproliferative disorders (PTLD) and lymphomas in immunocompromised individuals represent significant clinical challenges, with a limited understanding of their pathogenesis. We investigated a PTLD cohort (n = 50) consisting of 'early lesions' (infectious mononucleosis-like PTLD, plasmacytic and follicular hyperplasias), polymorphic PTLD and post-transplant diffuse large B-cell lymphomas (PT-DLBCL). The study also included 15 DLBCL with autoimmune/immunocompromised backgrounds (IS-DLBCL) and 14 DLBCL, not otherwise specified (DLBCL, NOS), as control.

The effect of the menstrual cycle phases on back squat performance, jumping ability and psychological state in women according to their level of performance -a randomized three-arm crossover study.

Objective: The influence of the menstrual cycle on practical power performance such as barbell back squats and jumping performance in women has not yet been fully investigated. In addition, the performance level of athletes has not been considered in previous studies. This study aimed to investigate the influence of different cycle phases on acute back squat performance, jumping ability and psychological state concerning the performance level.

Cardiorespiratory Markers Relate to Change-of-Direction Performance During Incremental Endurance Tests and Friendly Matches in Professional Male Handball Players.

Purpose: To compare the standard Yo-Yo intermittent recovery (IR) test and an agility Yo-Yo IR test with a higher number of change-of-direction movements to cardiorespiratory match performance.

Methods: The study included 11 professional male handball players (age 24.5 [4.
