The Acute Effects Of Weighted Vest Running On Substrate Utilization And Energy Expenditure, Troy M. Purdom Mr.
The Acute Effects Of Weighted Vest Running On Substrate Utilization And Energy Expenditure, Troy M. Purdom Mr.
Health, Exercise, and Sports Sciences ETDs
This study evaluated the effect of weighted vest running (WVR) on fatty acid oxidation (FAox) and caloric expenditure at pre-designated exercise intensities (60,65,70,75,80% VO2max). Seventeen recreationally trained runners (9 men and 8 women) performed four separate graded exercise tests (GXT) separated by 24 hours each. The first graded exercise test (GXT) was performed to establish the workloads at specific exercise intensities. The following three GXTs tested WVR with a control (no vest), 5% body mass (BM) vest, and 10%BM vest, using 3-minute incrementally increasing steady rate stages. Indirect calorimetry was used to measure both FAox (g/min) and caloric …
Effect Of Branched-Chain Amino Acid Supplementation On Recovery Of Performance And Muscle Damage, & Autophagy And Heat Shock Protein Response, Trisha Vandusseldorp
Effect Of Branched-Chain Amino Acid Supplementation On Recovery Of Performance And Muscle Damage, & Autophagy And Heat Shock Protein Response, Trisha Vandusseldorp
Health, Exercise, and Sports Sciences ETDs
Purpose: To investigate: 1) if branched-chain amino acid supplementation (BCAA) enhances recovery from acute, eccentric resistance exercise as measured by indirect markers of muscle damage, and 2) the impact of acute, eccentric resistance exercise on markers of autophagy and heat shock protein during recovery. Methods: Twenty resistance-trained males were randomly assigned to eight days of BCAA or PLCB and adhered to a diet consisting of 1.2 g/kg/d protein. On day five, all subjects completed 10x8 eccentric squats at 70% one repetition maximum (1RM), followed by 5x20 split jumps. Plasma creatine kinase (CK), erythrocyte glutathione, vertical jump (VJ), maximal voluntary isometric …
Harness Suspension Stress Physiological And Safety Assessment, James Marc Beverly
Harness Suspension Stress Physiological And Safety Assessment, James Marc Beverly
Health, Exercise, and Sports Sciences ETDs
Background: No robust trials including imaging or biomarkers have been performed to evaluate the possible stress of hanging motionless in a harness (harness suspension stress -HSS). Untoward effects are from case reports and sparsely documented data, leaving the topic open to debate. No cause-effect relationship has been established, therefore providing no guide to diagnostic, prognostic, or therapeutic evaluation or treatment for possible detrimental effects of HSS. Expert opinion provides the majority of the literature concerning HSS. Many of the effects of HSS have been correlated to other syndromes or causes, but none have been excluded, and none have been established. …
The Importance Of Leadership: An Investigation Of Effects Of Transformational Leadership On Middle School Students Intrinsic Motivation And Expectancy-Value In Physical Education, Minhyun Kim
Health, Exercise, and Sports Sciences ETDs
The leadership practices exhibited by physical education teachers have been found to have a significant impact on promoting students learning. The main purpose of this study was to explore: (a) differences on middle school students' perception regarding expectancy-value and intrinsic motivation according to their grade, gender, and ethnicity, (b) the relationship between physical education teachers' transformational leadership and middle school students' expectancy-value and intrinsic motivation. To conduct this study, three questionnaires were employed: transformational teaching questionnaire (Beauchamp et al., 2010), expectancy-value questionnaire (Duncan & Tammen, 1989), and intrinsic motivation index (Eccles & Wigfield, 1995). A total of 295 middle school …
