The influence of a vegan diet on body composition, performance and the menstrual cycle in young, recreationally trained women- a 12-week controlled trial.

Background: An increasing number of people, including recreational trained individuals, choose not to consume animal products and follow a vegan diet. Young women in particular are switching to a vegan diet. Studies have shown no difference in performance and muscle adaptations between a balanced vegan and an omnivorous diet.

Six weeks of polarized functional interval training with large training load reductions does not affect performance gains compared to traditional workouts.

Purpose: High-intensity functional interval training (HIFT) is predominantly composed of high exercise training intensities (HiT) and loads. Both have been linked to a higher risk of overtraining and injuries in inexperienced populations. A polarized training approach is characterized by high amounts of low-intensity training (LiT) and only approximately 5%-20% HiT.

Comparing strategies for the mitigation of SARS-CoV-2 airborne infection risk in tiered auditorium venues.

The COVID-19 pandemic demonstrated that reliable risk assessment of venues is still challenging and resulted in the indiscriminate closure of many venues worldwide. Therefore, this study used an experimental, numerical and analytical approach to investigate the airborne transmission risk potential of differently ventilated, sized and shaped venues. The data were used to assess the magnitude of effect of various mitigation measures and to develop recommendations.

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.

A genetically encoded actuator boosts L-type calcium channel function in diverse physiological settings.

L-type Ca channels (Ca1.2/1.3) convey influx of calcium ions that orchestrate a bevy of biological responses including muscle contraction, neuronal function, and gene transcription.
