Background: High-Intensity Multimodal Training (HIMT) refers to all styles of high-intensity combined aerobic, resistance and/or bodyweight exercise. Previous heterogeneity in exercise prescription and reporting in HIMT reduces the understanding of which factors should be considered when prescribing HIMT (e.g.

Objectives: Elite sport coaches often rely on their discretion when assisting athletes struggling with mental health, with clear guidelines yet to be broadly adopted. This study aimed to explore how coaches perceive their role in athlete mental health and their role clarity.

Design: This study employed a descriptive qualitative approach with semi-structured interviews.

Regular physical activity supports children's physical and psychological health and wellbeing, and provides opportunities to build social and emotional skills such as resilience, confidence, and self-efficacy. Research has demonstrated that mass participant sporting events can serve as important social and environmental correlates of physical activity. This study sought to explore parents and children's perceived motivations and perspectives of participation in the Australian Sanitarium Weet-Bix Kids TRYathlon (a non-competitive triathlon series), on children's health and well-being.

Background: High-intensity multimodal training (HIMT) is emerging as a popular training method that combines aerobic and resistance training throughout a single exercise session. The current literature is limited by a lack of terminology that broadly encompasses all styles of combined aerobic and resistance training. The magnitude of chronic or long-term (i.

This review aimed to identify and assess existing evidence of the impact of sport and physical activity programs on mental health and social and emotional wellbeing outcomes within young Aboriginal and Torres Strait Islander people. The review also aimed to highlight limitations of current practice within the research area. A systematic search of literature was undertaken on three peer-reviewed databases (PsycINFO, MEDLINE and SPORTSDiscus) and grey literature from January to March 2021.

A conceptual framework has a central role in the scientific process. Its purpose is to synthesize evidence, assist in understanding phenomena, inform future research and act as a reference operational guide in practical settings. We propose an updated conceptual framework intended to facilitate the validation and interpretation of physical training measures.

Issue Addressed: Running since 1999, the Sanitarium Weet-Bix Kids TRYathlon (SWKT) is the world's largest triathlon series for children and adolescents up to 16 years. This report seeks to describe participants of the TRYathlon and their perceptions of the event.

Methods: An online survey was made available to Australian parents/guardians of participants enrolled in the 2020 SWKT.

Background: Athlete-reported outcome measures (AROMs) are frequently used in research and practice but no studies have examined their psychometric properties.

Objectives: Part 1-identify the most commonly used AROMs in sport for monitoring training responses; part 2-assess risk of bias, measurement properties, and level of evidence, based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines.

Study Appraisal And Synthesis Methods: Methodological quality of the studies, quality of measurement properties, and level of evidence were determined using the COSMIN checklist and criteria.

Purpose: To examine whether concurrent heat and intermittent hypoxic training can improve endurance performance and physiological responses relative to independent heat or temperate interval training.

Methods: Well-trained male cyclists (N = 29) completed 3 weeks of moderate- to high-intensity interval training (4 × 60 min·wk-1) in 1 of 3 conditions: (1) heat (HOT: 32°C, 50% relative humidity, 20.8% fraction of inspired oxygen, (2) heat + hypoxia (H+H: 32°C, 50% relative humidity, 16.

Context: Professional dance is a demanding physical activity with high injury rates. Currently, no epidemiologic data exist regarding the incidence of injury and illness together with training load (TL) over a long period of time.

Objective: To provide a detailed description of injury, illness, and TL occurring in professional contemporary dancers.

Purpose: To provide details on the nature and symptomatic profile of training maladaptation in competitive resistance-based athletes to examine whether there are symptoms that may be used as prognostic indicators of overtraining. Identifying prognostic tools to assess for training maladaptation is essential for avoiding severe overtraining conditions.

Methods: A Web-based survey was distributed to a cross-sectional convenience sample of competitive athletes involved in sports with a significant resistance-training component.

Background: The balance between training stress and recovery is important for inducing adaptations to improve athletic performance. However, continuously high training loads with insufficient recovery may cause fatigue to accumulate and result in overtraining. A comprehensive systematic review is required to collate overtraining literature and improve the current understanding of the mechanisms underlying functional overreaching (FOR), non-functional overreaching (NFOR) and the overtraining syndrome (OTS) in resistance training.

As part of both training and active service, military members can be exposed to prolonged periods of sleep loss. Given the extent of physical and cognitive performances viewed as critical to successful military performance, such sleep disruption may present risk to health and performance. The primary aim of this narrative review was to investigate evidence on the effect of inadequate sleep on measures of aerobic capacity, anaerobic capacity, muscular strength and muscular endurance in military personnel.

Purpose: To describe the training demands of contemporary dance and determine the validity of using the session rating of perceived exertion (sRPE) to monitor exercise intensity and training load in this activity. In addition, the authors examined the contribution of training (ie, accelerometry and heart rate) and non-training-related factors (ie, sleep and wellness) to perceived exertion during dance training.

Methods: Training load and ActiGraphy for 16 elite amateur contemporary dancers were collected during a 49-d period, using heart-rate monitors, accelerometry, and sRPE.

Purpose: This investigation examined the ergogenic effect of short-term oral N-acetylcysteine (NAC) supplementation and the associated changes in redox balance and inflammation during intense training.

Methods: A double-blind randomized placebo-controlled crossover design was used to assess 9 d of oral NAC supplementation (1200 mg·d) in 10 well-trained triathletes. For each supplement trial (NAC and placebo), baseline venous blood and urine samples were taken, and a presupplementation cycle ergometer race simulation was performed.

The ability to grow keratinocyte stem cells (KSCs) in 3D culture is an important step forward for investigating the physiological properties of these cells. In the epidermis, KSCs are subject to various types of mechanical stress. To study the effects of mechanical stress on KSCs, monolayer cultures are limited as the KSCs can only form cell-cell contacts in one plane and to prevent differentiation, KSCs are grown in low (0.
