The Significance of Time to Exhaustion at the Velocity at VO2Max (open access)

The Significance of Time to Exhaustion at the Velocity at VO2Max

There were two primary goals in this investigation. The first goal was to determine if inter-individual variability in time to exhaustion at the velocity associated with V02max (Tlim at Vmax) was explained by anaerobic capacity (AC), Vmax, anaerobic threshold (AT), and/or a combination variable in the form [AC • (Vmax - vAT)^-1]. The second goal was to determine if AC could be predicted from Tlim at Vmax, AT, and/or a combination variable in the form [Tlim • (Vmax - vAT)].

Measurement of Mood State Changes Throughout a Competitive Volleyball Season (open access)

Measurement of Mood State Changes Throughout a Competitive Volleyball Season

Mood state changes have been assessed in endurance sport athletes such as swimmers, distance runners and rowers. However, much less is known about the psychological changes that occur in team sport athletes. The purpose of this study was to assess mood state changes of intercollegiate female volleyball players across a competitive season.

Attentional Focus Strategies of Multi-Sport Athletes. (open access)

Attentional Focus Strategies of Multi-Sport Athletes.

The purpose of this study was to determine (a) the attentional focus strategies used by triathletes during the three stages of an Olympic distance triathlon, (b) if level of experience influences the attentional focus strategies used by triathletes, and (c) whether there is a relationship between athletes finishing times and the attentional strategies used in each stage of the race. Triathletes (N = 160) completed the Triathlon Attentional Focus Inventory, which measured association and dissociation during the swim, bike, and run. One-way ANOVAs revealed significant differences between the athletes' level of experience and the attentional strategies used, as well as differences between the athletes overall race time and the attentional strategies used during each stage of the triathlon. Athletes with more experience associated more during the race, whereas athletes with less experience dissociated more throughout the race.

The Effect of Mode and Intensity on Vo2 Kinetics in the Severe Intensity Domain (open access)

The Effect of Mode and Intensity on Vo2 Kinetics in the Severe Intensity Domain

The purpose of this study was to evaluate the effect of mode and intensity on VO2 kinetics in the severe intensity domain. Seventeen participants completed 3-7 tests each on a cycle ergometer and treadmill. For each test, Tfatigue, VO2max, Tmean response, VO2GAIN, TVO2max and T@VO2max were determined. Linear regression techniques were used to describe the relationship between TVO2max and Tfatigue . VO2max values were higher in running. The VO2 response profile was faster for running than cycling and faster at higher intensities. The faster VO2 response in running may be associated with larger active muscle mass or differences in muscle activation patterns. The faster response at higher intensities may suggest that VO2 response is driven by O2 demand.

Responses During Exercise at 90% and 100% of the Running Velocity Associated with VO2max (vVO2max) (open access)

Responses During Exercise at 90% and 100% of the Running Velocity Associated with VO2max (vVO2max)

Six male long-distance runners participated in this study to evaluate the responses to exercise at 90% and 100% vV02max. Subjects participated in five maximal exercise tests: one incremental, three tests at 90% vV02max, and one test at 100% vV02max. The results of this study demonstrate that V02max can be elicited in a constant-velocity test at 90% vV02max.

Resilience and Health Outcomes in Patients with Traumatic Injury (open access)

Resilience and Health Outcomes in Patients with Traumatic Injury

Due to the increasing healthcare costs and reduced length of hospital stay it is becoming increasingly important to identify individuals who are ‘at risk’ of experiencing long-term health issues. The purpose of the study was to: (1) determine if resilience, self efficacy and depression changed from inpatient to 3-month follow up; (2) examine the relationship between resilience, self efficacy, depression, and quality of life (social roles/activity limitations) at inpatient and 3-month follow up; and (3) identify if resilience at inpatient is related to change scores in selfefficacy and depression at 3-month follow up. Results from the paired sample t-test indicated that participants did not experience a significant change from inpatient to 3-month follow up in resilience or self-efficacy, but a significant decrease in depression was observed. Findings also indicated significant correlations between resilience, self-efficacy, and depression during inpatient stay and resilience, self-efficacy, depression, and quality of life at 3-month follow up. However, there was no relationship found between resilience and change scores in self-efficacy and depression. Future resilience research should continue to identify the variables that are most strongly related to resilience so effective interventions can be developed that improve rehabilitation outcomes, decrease secondary and chronic conditions as well as …

Effects of Strength on Selected Psychomotor Performances of Healthy and Frail Elderly Females (open access)

Effects of Strength on Selected Psychomotor Performances of Healthy and Frail Elderly Females

The purpose of this study was to compare muscle strength and psychomotor performance measures in healthy (n = 18) and frail (n = 21) groups of elderly women utilizing movements requiring various amounts of strength and ballistic action. Subjects were community-dwelling females ranging in age from 66-92 years. Evaluations of functional assessment of motor skills and grip strength occurred. Psychomotor performance was measured through production of aiming movements on a Digitizing Tablet. RT, MT, and movement kinematics (e.g., peak velocity, deceleration, movement adjustments) were evaluated. Differences between groups were apparent in quantity and quality of movement. Healthy subjects were stronger and faster than frail subjects, producing smoother movements with fewer adjustments. Strength appears to differentially affect healthy and frail samples and merits further exploration.
