“…Results of this study with the internal investigation of Eizadi et al on 25 Adolescent corresponds (6) in the other study found a nonlinear relationship between VO2 and HR averaged over the subjects (29). On the other hand, in a study conducted on children, the heart rate was a factor used to estimate aerobic capacity (30). Even in UK, according to a study on men, heart rate with age is a determining factor to estimate aerobic capacity (31) In the study of vema et al to estimates the aerobic capacity, several different techniques were used in which the heart rate was measured during the work activity and it has been one appropriate technique for estimating aerobic capacity (32).…”

Received: August 2013, Accepted: January 2014Background: To establish a balance between work (physical exercise) and human, the aerobic capacity (VO2max) could be used as a measure. Assessing the heart rate in association to physiological symptoms is the most commonly used tool for the assessment of fatigue during physical exercise. This study aimed to investigate the association between the aerobic capacity and the heart rate of workers from the casting industry. Materials and Methods:The subjects were 200 male workers selected from casting industry in Isfahan using random sampling method. The subjects were examined using ergometer in accordance with Astrand 6 minutes cycle test protocol, Then, the VO2max was estimated using the formula proposed by American College of Sports Medicine (ACSM). The heart rates were monitored and recorded automatically. Finally, the results were analyzed by SPSS 20 statistical software package. Results:The results illustrated that there was a strong correlation between heart rate (HR) and VO2max (r=0.991, P<0.001). The regression analysis of the quadratic equation indicated that there was a significant association between the VO2max and the heart rate. Conclusion: As the results indicated there was a strong association between heart rate and VO2max, indicating the fact that with the increase in heart rate during physical activity, aerobic capacity is reduced, and the heart rate could be used as a prediction measure to estimate VO2max.

“…Heart rate was recorded throughout the test and for two minutes following completion of the protocol. Aerobic fitness (Vo 2 max ml/kg.min) was calculated employing a standard conversion formula using the subject's heart rate response to the exercise activity [23].…”

The purpose of this study was to determine if a college course in Personal Health and Fitness that includes Fitness Interns (FI) can impact dietary intake, physical fitness and attitudes towards a healthy dietary intake and physical activity among college students. Two different versions of the intervention were delivered as a component of a 3-credit hour undergraduate "Personal Health and Fitness" course. The content of this course included a classroom lecture, weekly homework and a weekly meeting with FI who was an upperclassmen who was enrolled in Exercise Physiology. During the first version of the intervention (Class 1, n=20) the subjects met with the FI once per week to complete assigned homework. Subjects exposed to the second intervention (Class 2, n=29) also met with a FI once per week to complete the homework assignment and to engage in at least 30 minutes of a physical fitness activity per week with the FI. The course content and homework was based upon the Theory of Planned Behavior and was designed to improve the dietary intake and physical activity of the subjects in both intervention groups. Control subjects (n=24) who volunteered for the study were not registered for "Personal Health and Fitness" and had no access to the course content or the FIs. During the first and last weeks of fall semester all subjects completed an assessment of their dietary intake, physical fitness and attitudes (control beliefs and outcome expectations).Both intervention groups exhibited significant (p<.05) reduced caloric intake and improvements in physical fitness and attitudes toward a healthy dietary intake and physical activity with Class 2 exhibiting a greater number of improvements compared to Class 1. The control group did not change on any outcome variables. These findings indicate the efficacy of a "Personal Health and Fitness" course on antecedents to weight gain among college students.

“…Test has been widely used in the exercise physiology literature to estimate cardiovascular fitness and has been shown to be a good correlate of VO2 max using instrumented measures (Jacks, Moore, Topp, & Bibeau, 2008;Kasch, Phillips, Ross, Carter, & Boyer, 1966). …”

Metabolic Mechanisms of Vocal Fatigue

Vocal fatigue is among the most debilitating conditions affecting individuals with voice disorders. Impressions about mechanisms potentially underlying vocal fatigue have varied depending on how fatigue is defined, participants studied, and measures made, thereby impacting the selection of treatment strategies that may alleviate the condition. However, little is currently known about actual metabolic mechanisms of vocal fatigue. The current study aimed to address this issue by investigating the hypothesis that neuromuscular inefficiency, cardiovascular recovery deficits, or both, may play a role in fatigue. The approach replicated well-vetted approaches in exercise physiology.Metabolic profiles of subjects with vocal fatigue were assessed using gas exchange measures in comparison to two non-fatigue groups: vocally healthy and cardiovascular trained individuals, recruited based on results from a newly vetted questionnaire, the Vocal Fatigue Index (VFI) and laryngeal examination. Participants read out loud at two different loudness levels for a duration of 5 minutes for each task with periods of rest between tasks. Metabolic cost for and recovery time from reading were same across all groups. Oxygen uptake and recovery kinetics (EPOC), ratings of perceived exertion revealed interesting patterns in individuals with vocal fatigue compared to cardiovascular trained individuals in particular.Specifically, slow oxygen uptake kinetics in the vocal fatigue compared to the cardiovascular iv trained group pointed to utilization of anaerobic energy source to meet the demands of the reading task in the vocal fatigue group, suggesting neuromuscular inefficiency. In contrast, rapid oxygen uptake kinetics in the cardiovascular trained group pointed to utilization of aerobic energy sources and greater neuromuscular efficiency. Similarly, a greater number of individuals in vocal fatigue and vocally healthy groups showed an increase in oxygen consumption post reading (EPOC) compared to the cardiovascular trained group, indicating possible cardiovascular recovery deficits in the former groups.In addition to uncovering potential mechanisms underlying vocal fatigue, including neuromuscular inefficiency and cardiovascular recovery deficits, results from the present study highlight the potential importance of aerobic training to generate aerobic energy required for vocal task demands for both ease of task performance and recovery from it. In sharp contrast to the situation for voice, fatigue as a common physical phenomenon more generally has received extensive attention in the physical therapy, sports medicine, and exercise physiology literature. Three broad schools of thought identify mechanisms pertaining to the origins of physical fatigue: (1) peripheral mechanisms (Allen, Lamb, & Westerblad, 2008;Asmussen, 1979;Edwards, 1981;Fitts, 1994;Westerblad, Allen, & Lannergren, 2002;Westerblad, Lee, Lannergren, & Allen, 1991), (2) The next pages and chapters provide pertinent background information on vocal fatigue, fatigue as understood ...
