Individuals that are physically active have greater cardiorespiratory fitness and skeletal muscle strength than those that are physically inactive. Although VO2maxis commonly used to estimate cardiorespiratory fitness, in older adults, leg strength may also influence VO2max. The PURPOSE of this study is to examine the relationship between VO2max and leg strength in physically active vs. physically inactive older adults. METHODS: Twenty-four older adults (12 physically active (PA; 62.1±5.0 yrs), 12 physically inactive (PI; 63.9±5.1 yrs)) performed a two-stage treadmill test to estimate VO2max. Leg strength was assessed by 8-repitition maximum (8RM) …

Impacts Of Menstrual Cycle Phase On Measures Of Body Composition, Kristina M. Woodford, Abigail R. Champion, Lauren E. Coleman, Heather Webb
International Journal of Exercise Science: Conference Proceedings
Fluctuations in body weight and water retention are common complaints made by many women as a result of hormonal changes that accompany menstrual cycle (MC). Specific research regarding how the different phases of the menstrual cycle may impact body composition measures have been limited, and typically are examined as a subset of other variables. As lean body tissue is approximately 73% water, fluctuations in body water due to changes in a women’s MC may influence measurements of body composition. PURPOSE: To investigate whether phases of the MC have an impact on common measures of body composition. METHODS: A total of …

International Journal of Exercise Science: Conference Proceedings
Rugby sevens (7s) is an anaerobic contact sport consisting of seven players per team, with two 7-minute halves per match played in tournament style with several matches over up to a three-day event. However, due to the nature of the collegiate game, less funding, and their academic schedule, the tournaments are commonly consolidated into one day (minimum 3, as many as 6 matches). While there are six positions in 7s, this study divided them into three groups: Forwards (FW), Backs (BK), and Scrum halves (SH). Purpose: The purpose of this investigation was to identify the physiological and physical demands …

Sex Differences In Power Output At Maximal Load During The Barbell Squat, Lyndsey T. Mccallister
International Journal of Exercise Science: Conference Proceedings
When maximal muscular power outputs are examined relatively, sex differences appear to be non-existent. In terms of absolute power, however, significant differences persist between sexes. In both cases, the majority of metrics are obtained at optimal loads for power outputs. However, little is known in regards to differences in power outputs at maximal strength capacity of men and women. PURPOSE: The current investigation aimed to identify sex differences of concentric (C) and eccentric (E) power measures at maximal load during the barbell back squat (SQ). METHODS: A total of 8 participants (4 men and 4 women) completed one …

Differences In Bone Mineral Density At The Femoral Neck And Lumbar Regions Across Female Soccer Players, Olympic Lifters And Power Lifters, Woohyoung Jeon, John Michael Harrison, Philip Stanforth, Lisa Griffin
International Journal of Exercise Science: Conference Proceedings
Power lifting can improve total body bone mineral density (BMD), but improvements in the regions most susceptible to injury (femoral neck and lumbar vertebrae) have not been demonstrated. Soccer players, who engage in odd-impact loading, have greater BMD at the femoral neck than sedentary controls. Olympic lifting involves both high- and odd-impact loading at the femoral neck and lumbar regions, but comparisons in BMD across sport-specific athletes have not yet been made. PURPOSE: To examine differences in total BMD and BMD at the femoral neck and lumbar vertebrae between female power lifters (PL), Olympic lifters (OL), soccer players (SP) and …
