Body Mass Index Of Masters Basketball Players, Joe Walsh, Mike Climstein, Ian Timothy Heazlewood, Mark Debeliso, Kent Adams, Stephen Burke, Jyrki Kettunen

Joe Walsh

Abstract. Aim and Scope: Thousands of masters athletes participate quadrennially in the World Masters Games (WMG). However, this unique cohort remains under investigated. With a need for multifaceted solutions to the global obesity epidemic, investigating special populations such as those competing in sport at mature-older ages may further the understanding of the nexus between aging, physical activity and obesity. The aim of this cross-sectional comparative study was to investigate body mass index (BMI) within the WMG competitors in context with national populations and health guidelines. We hypothesized that the prevalence of obesity in the WMG cohort would be less than …

Hawley Almstedt

The purpose of this investigation was to assess the effectiveness of variable resistance as provided through elastic plus free weight techniques in college aged males and females. Twenty novice lifters were randomly assigned to a traditional free weight only (6 males and 5 females) or elastic band plus free weight group (5 males and 5 females) and 9 more normally active controls (5 males and 4 females), were recruited to maintain normal activity for the duration of the study. No differences existed between control, free weight and elastic band at baseline for age, body height, body mass, body mass index, …

Outcomes Of Early Versus Late Nephrology Referral In Chronic Kidney Disease – A Systematic Review, Neil A. Smart Assoc. Prof.

Neil Smart

Background As late provision of specialist care, prior to starting dialysis therapy, is believed to be associated with increased morbidity and mortality, a systematic review was undertaken to evaluate clinical outcomes relating to early versus late referral of patients to nephrology services.

Methods: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE were searched up until September 2008 for studies of early versus late nephrology referral in adult (>18 years) patients with chronic kidney disease. Early referral was defined by the time period, at which patients were referred to a nephrologist.

Findings: No randomized, controlled trials were found. …

Load Carriage And The Female Soldier, Rob Marc Orr, Venerina Johnston, Julia Coyle, Rodney Pope

Rob Marc Orr

This paper reviews the physiological, biomechanical and health impacts of load carriage on the female soldier and extends to include issues acknowledged as impacting on the female athlete and hence the female soldier. Physiological factors such as fat mass, strength, aerobic endurance and biomechanical factors such as stride length and forward lean have the potential to increase the energy cost of load carriage and cause injury. The female athlete triad, iron deficiency, pelvic floor muscle dysfunction and military equipment issues can likewise reduce female soldier performance and increase injury risk. Research evidence is presented to inform the development and implementation …

Acute Arginine Supplementation Fails To Improve Muscle Endurance Or Affect Blood Pressure Responses To Resistance Training., Beau Kjerulf Greer, Brett T. Jones

Beau K. Greer

Dietary supplement companies claim that arginine supplements acutely enhance skeletal muscular endurance. The purpose of this study was to determine whether acute arginine α-ketoglutarate supplementation (AAKG) will affect local muscle endurance of the arm and shoulder girdle or the blood pressure (BP) response to anaerobic exercise. Twelve trained college-aged men (22.6 ± 3.8 years) performed 2 trials of exercise separated by at least 1 week. At 4 hours before, and 30 minutes before exercise, a serving of an AAKG supplement (3,700 mg arginine alpha-ketoglutarate per serving) or placebo was administered. Resting BP was assessed pre-exercise after 16 minutes of seated …

Branched-Chain Amino Acid Supplementation Lowers Perceived Exertion But Does Not Affect Performance In Untrained Males., Beau Kjerulf Greer, James P. White, Eric M. Arguello, Emily M. Haymes

Beau K. Greer

The purpose of this study was to determine whether branched-chain amino acid (BCAA) supplementation affects aerobic performance, ratings of perceived exertion (RPE), or substrate utilization as compared with an isocaloric, carbohydrate (CHO) beverage or a noncaloric placebo (PLAC) beverage. Nine untrained males performed three 90-minute cycling bouts at 55% VO₂ peak followed by 15-minute time trials. Subjects, who were blinded to beverage selection, ingested a total of 200 kcal via the CHO or BCAA beverage before and at 60 minutes of exercise or the PLAC beverage on the same time course. RPE and metabolic measurements were taken every 15 minutes …

Purposeful Engagement Of First-Year Division I Student-Athletes, Keith Harrison

Dr. C. Keith Harrison

This study examined the extent to which transitioning, first-year student-athletes engage in educationally sound activities in college. The sample included 147 revenue and nonrevenue first-year student-athletes who were surveyed at four large Division 1-A universities. Findings revealed that revenue and nonrevenue first-year student athletes differed regarding their academic and athletic identities. Transitioning revenue student-athletes rated themselves as having slightly higher athletic identities, yet lower academic identities compared to their nonrevenue counterparts. The findings from this study also indicated that the kinds of effective educational practices that first-year student-athletes engage in have a positive influence on their academic self-concept. These findings …

Physique And Body Composition In Soccer Players Across Adolescence, Pantelis Nikolaidis, Nickos Karydis

Pantelis Nikolaidis

PURPOSE: Although the contribution of physique and body composition in soccer performance was recognized, these parameters of physical fitness were not well-studied in adolescent players. Aim of this study was to investigate physique and body composition across adolescence. METHODS: Male adolescents (N=297 aged 12.01-20.98 y), classified into nine one-year age-groups, child (control group, N=16 aged 7.34-11.97 y) and adult players (control group, N=29 aged 21.01-31.59 y), all members of competitive soccer clubs, performed a series of anthropometric measures (body mass, height, skinfolds, circumferences and girths), from which body mass index (BMI), percentage of body fat (BF%), fat mass (FM), fat …

Football: An Intransitive Endeavour, Joe Walsh, Ian Timothy Heazlewood

Joe Walsh

It has long been established that competitions should be structured to give each team a fair chance of winning. The aim of this research paper was, considering similarities of shared parameters between codes, to investigate intransitivity in football codes. Variables effecting probabilistic outcomes of games were identified for the football codes: soccer, gridiron, rugby union, rugby league and touch football. An algebraic probabilistic model for obtaining tactical advantage in individual transition states was developed. Hypothetical teams were constructed in order to test the possibility of intransitive games states. It was clear that intransitivity could logically exist for a variety of …

Injury Incidence In Football Code Athletes During Preparation For The World Masters Games, Joe Walsh, Mike Climstein, Stephen Burke, Ian Timothy Heazlewood, Kent J. Adams, Mark Debeliso, Jyrki Kettunen

Joe Walsh

There is growing evidence that physical activity across the lifespan is beneficial for improved health. However older athletes may display an increased range of pathologies and physiological changes due to the aging process. These factors may result in increased injury risks, particularly when participating in highly competitive sport. The World Masters Games (WMG) is the largest international sporting competition in terms of participant numbers. Yet this cohort of athletes remains proportionately under investigated.

It was hypothesized that injury trends would be similar in incidence and location to a comparative (elite soccer) population. An online survey was utilized to investigate the …

Load Carriage And Its Force Impact, Robin Orr, Rodney Pope, Verenina Johnston, Julia Coyle

Rodney P Pope

Extract:
Just as history records that military personnel have been carrying heavy loads for over two millennia (Orr, 2010), so too does it show their impact on military force sustainment and combat effectiveness. Around 800BC, the heavy loads carried by Assyrian soldiers reduced their mobility and led them to experiment continually with their shields in order to lighten their loads (Gabriel, 2002). Around 400BC, the long marches of Cyrus’ ‘infamous 10,000’, an army of Greek mercenaries accompanied by Xenophon, would have resulted in numerous stress fractures, torn ligaments, muscle damage, blisters and abrasions. While some of these injuries can be …
