CONVENTIONAL vs COMPLEX TRAINING: A SET BY SET AND SESSIONAL COMPARISON OF KINETIC AND KINEMATIC VARIABLES

The purpose of this study was to investigate the effects of complex sets on kinetic and kinematic variables in a countermovement jump (CMJ) compared to a conventional training session. Twenty-three recreationally trained males completed two familiarisation and two experimental conditions. No significant differences (

CONVENTIONAL vs COMPLEX TRAINING: A SET BY SET AND SESSIONAL COMPARISON OF KINETIC AND KINEMATIC VARIABLES

The purpose of this study was to evaluate moments and shear forces at the hip and knee during step ups and single leg squats. Subjects were 12 weight trained adults. Each subject performed 3 repetitions of step ups and single leg squats using 70% of 1 repetition maximum. 2 X 2 (lift X phase (eccentric/concentric)) repeated measures ANOVAs were performed for each dependent variable. Significant interaction effects (

Promoting Awareness Of, And Sharing Good Practices On, Supporting Engineering Students With Disabilities

The amount of literature that focuses on diversity and inclusion within engineering education continues to grow. However, research traditionally focuses on gender, and despite the United Nations Convention for the Rights of Persons with Disabilities (CRPD) being passed in 2016, there is still a lack of work which describes the experience of students with disabilities....Robot Dynamic

Characteristics of the female landing pattern

"This research aimed to explore and better understand intervention protocols and their effect on lower limb control associated with anterior cruciate ligament (ACL) injury. A fundamental and unique aspect of this investigation was to establish a lab-based testing protocol that successfully mimicked actual game play. [...]This research validated a lab-based measure that best mimicked game-play to use as a pre- and post- testing measure for two common methods used in current ACL intervention strategies. In addition, further understanding of the effects of a landing training and dynamic balance training program were found."Doctor of Philosph

Anterior cruciate ligament injuries in Australian football: Should women and girls be playing? You\u27re asking the wrong question

Anterior cruciate ligament (ACL) injuries have been a rising concern in the early years of the women\u27s Australian Football League (AFLW), eliciting headlines of a â € knee crisis\u27 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. We propose that an approach addressing environmental and sociocultural factors, along with biological determinants, is required to truly challenge the ACL injury problem in the AFLW. Sports science and medicine must therefore strive to understand the whole system of women in AF, and question how to address inequities for the benefit of the athletes. © © Author(s) (or their employer(s)) 2020.

Patriarchy’s Link to Intimate Partner Violence: Applications to Survivors’ Asylum Claims

Eligibility for asylum among survivors of intimate partner violence (IPV) has recently been contested. We summarize social science evidence to show how survivors generally meet asylum criteria. Studies consistently show a relationship between patriarchal factors and IPV, thereby establishing a key asylum criterion that women are being persecuted because of their status as women. Empirical support is also provided for other asylum criteria: Patriarchal norms contribute to state actors’ unwillingness to protect survivors, and survivors’ “political opinions” are linked to an escalation of perpetrators’ violence. The findings have implications for policy reform and support of individual asylum-seekers

THE INFLUENCE OF MUSCULAR ACTIVATION PROFILES ON LOWER LIMB BIOMECHANICS DURING A SPORT-SPECIFIC LANDING TASK

The purpose of this study was to identify the muscular activation profiles utilised by female athletes during a sport-specific landing task, and examine the effects of varying profiles on biomechanical anterior cruciate ligament (ACL) injury risk factors. Muscular activation profiles were identified from electromyography data using a combination of principal component and cluster analysis methods, with the neuromuscular and biomechanical characteristics of profiles compared. Various muscular activation characteristics contributed to the presence of lower limb biomechanical patterns consistent with ACL injury risk factors. Reduction of ACL injury risk may be achieved by targeting these muscular activation characteristics via neuromuscular training programs

LOWER BODY MUSCULOTENDON UNIT FUNCTION DURING BOUNDING, HURDLE JUMPING AND RUNNING

To facilitate exercise prescription, this study compared the function of six lower limb musculotendon units during plyometric exercises with running. Fourteen distance runners performed overground running (3.89 m/s), bounding, and hurdle jumps. Computational simulations were used to compare musculotendon unit function, peak powers, and total work. Compared to running, the hurdle jumps had greater gluteus maximus peak power absorption (12.1%; SMD 0.65), and gluteus maximus (15.7%; SMD 0.51) and soleus (16.5%; SMD 0.92) total negative work. Hurdle jumps may be an appropriate exercise when higher eccentric loads of the gluteus maximus and soleus are required. Compared to running, bounding had increased gastrocnemius total negative work (63.8%; SMD 0.81) and may be suitable when eccentric overload of the gastrocnemius is desired

Interactions between apolipoprotein E, sex, and amyloid-beta on cerebrospinal fluid p-tau levels in the European prevention of Alzheimer's dementia longitudinal cohort study (EPAD LCS)

BACKGROUND: Alzheimer's Disease, the leading cause of dementia, is over-represented in females. The apolipoprotein E (APOE)ε4 allele is the strongest genetic risk factor for late-onset AD and is associated with aberrant cerebrospinal fluid levels (CSF) of total tau (t-tau), phosphorylated tau (p-tau), and amyloid-β (Aβ). There is some evidence that sex may mediate the relationship between APOE status and CSF tau, however, evidence is mixed. METHODS: We aimed to examine the interaction between sex, APOE ε4 status, CSF Aβ on t-tau and p-tau in 1599 mid-to-late life individuals without a diagnosis of dementia in the European Prevention of Alzheimer's Dementia (EPAD) longitudinal cohort study. FINDINGS: We found a significant interaction between APOE status, sex, and CSF Aβ on CSF p-tau levels (β = 0·18, p = 0·04). Specifically, there was a stronger association between APOE status and CSF Aβ(42) on CSF p-tau in males compared to females. Further, in females with high Aβ levels (reflecting less cortical deposition), ε4 carriers had significantly elevated p-tau levels relative to non-carriers (W = 39663, p = 0·01). However, there were no significant differences in p-tau between male ε4 carriers and non-carriers with high Aβ (W = 23523, p = 0·64). INTERPRETATION: An interaction between sex and cerebrospinal fluid Aβ may mediate the relationship between APOE status and CSF p-tau. These data suggest tau accumulation may be independent of Aβ in females, but not males.
