The chronic leukocyte and inflammatory cytokine responses of older adults to resistance training in normobaric hypoxia; a randomized controlled trial.

Trial Design: Older adults experience chronic dysregulation of leukocytes and inflammatory cytokines, both at rest and in response to resistance training. Systemic hypoxia modulates leukocytes and cytokines, therefore this study characterized the effects of normobaric hypoxia on the leukocyte and cytokine responses of older adults to resistance training.

Methods: 20 adults aged 60-70 years performed eight weeks of moderate-intensity resistance training in either normoxia or normobaric hypoxia (14.

The effects of normobaric hypoxia on the leukocyte responses to resistance exercise.

There is growing interest in the use of systemic hypoxia to improve the training adaptations to resistance exercise. Hypoxia is a well-known stimulator of the immune system, yet the leukocyte responses to this training modality remain uncharacterised. The current study characterised the acute leukocyte responses to resistance exercise in normobaric hypoxia.

Longitudinal association of physical activity during pregnancy with maternal and infant outcomes: Findings from the Australian longitudinal study of women's health.

Background: Physical activity has known benefits during pregnancy; however, the optimum volume of physical activity through the different stages of pregnancy is not well known.

Objectives: The aims of this study were to investigate the associations of physical activity volume in pregnant women in each trimester of pregnancy with maternal and infant outcomes.

Design: The study involved 1657 pregnant women from the Australian Longitudinal Study on Women's Health, who completed surveys from 2006 to 2012 (aged 28-39 years).

Physical activity knowledge, attitudes and behaviours of pre-clinical medical students attending an Australian university.

Background: Through the provision of advice and counselling, general practitioners (GPs) play an important part in promoting physical activity (PA). Lack of knowledge is a key barrier to engaging in such practice. Little is known about the knowledge and attitudes of current medical students and their preparedness to engage in PA promoting practice in the future.

"Prescriptive authority for psychologists: The next step": Correction.

Reports an error in "Prescriptive authority for psychologists: The next step" by Steven Eric Curtis, Samantha Hoffmann and Maeve O'Leary Sloan (, Advanced Online Publication, May 05, 2022, np). In the original article, changes were needed to clarify the timeline of state legalizations of prescriptive authority for psychologists (RxP) and the current status of RxP with regard to the Federal Bureau of Prisons (BOP). In the second paragraph of the "RxP From 2011 to Present" section, the citations relating to legalization in Idaho and Iowa were corrected, and the year in the Prescribing Psychologist reference was corrected in the References section and in text citations throughout.

The Role of Sports Clothing in Thermoregulation, Comfort, and Performance During Exercise in the Heat: A Narrative Review.

The aims of this review are to (1) summarise the current research of sports clothing as it relates to thermoregulation, comfort, and performance during exercise in the heat, (2) identify methodological limitations and gaps in the knowledge base of sports clothing, and (3) provide recommendations for exercise testing protocols to accurately assess the impact of sports clothing in athletic populations during exercise in the heat. Sports clothing consists of lightweight and breathable fabrics, surface treatments, and various designs which aim to enhance sweat evaporation and comfort during exercise in the heat. Sports clothing comprised of natural, synthetic, and chemically treated fabrics has been investigated during exercise of varying durations (15-120 min), intensities (20-70% VO max) and types (fixed intensity, incremental, self-paced), and in an array of climatic conditions (18-40 °C, 20-60% relative humidity).

The assessment of a novel lower body resistance garment as a mechanism to increase the training stimulus during running: a randomised cross-over study.

Background: This study examined the physiological and perceived impact of wearing a novel lower body resistance garment during exercise and recovery.

Methods: Using a randomised cross-over design, 15 recreationally-active males performed 2 × 10-min steady-state runs followed by a 10-min passive recovery with concomitant monitoring of oxygen consumption (V̇O), heart rate (HR) and rating of perceived exertion (RPE; exercise portion only), wearing either the resistance garment (experimental) or running shorts (control).

Results: During exercise, there was a trend for V̇O and RPE to be higher (4.

Behaviors and Actions of the Strength and Conditioning Coach in Fostering a Positive Coach-Athlete Relationship.

J Strength Cond Res 36(11): 3256-3263, 2022-A number of models have been developed to explain the various factors that affect coach-athlete interactions; however, they have had limited application to strength and conditioning (S&C).

Comparison of training responses and performance adaptations in endurance-trained men and women performing high-intensity interval training.

The efficacy of high-intensity interval training (HIIT) to elicit physiological and performance adaptations in endurance athletes has been established in men and to a lesser extent in women. This study compared lactate threshold (LT) and performance adaptations to HIIT between men and women. Nine male and eight female cyclists and triathletes completed trials to determine their LT and 40 km cycling performance before, and after 10 HIIT sessions.

Anterior cruciate ligament injuries in Australian football: should women and girls be playing? You're asking the wrong question.

Anterior cruciate ligament (ACL) injuries have been a rising concern in the early years of the women's Australian Football League (AFLW), eliciting headlines of a 'knee crisis' surrounding the league. There has been a focus on female biology as the primary factor driving the high rate of ACL injuries in the AFLW. Emphasising Australian football (AF) as being dangerous predominantly due to female biology may be misrepresenting a root cause of the ACL injury problem, perpetuating gender stereotypes that can restrict physical development and participation of women and girls in the sport.

The Coach-Athlete Relationship in Strength and Conditioning: High Performance Athletes' Perceptions.

The primary purpose of this study was to investigate high performance athlete perceptions of strength and conditioning coaches, specifically, (1) their character traits, (2) the effective behaviours that display these traits, and (3) how these relationships were fostered. Using the 3+1 C's model of coach-athlete relationships as a framework (Jowett, 2007), 12 semi-structured interviews were conducted with high performance athletes (six female; six male) representing a variety of sports (i.e.
