Purpose:To develop a sailing ergometer that accurately simulates upwind sailing exercise.Methods:A sailing ergometer that measures roll moment accompanied by a biofeedback system that allows imposing a certain quasi-isometric upwind sailing protocol (ie, 18 bouts of 90-s hiking at constantly varying hiking intensity interspersed with 10 s to tack) was developed. Ten male high-level Laser sailors performed an incremental cycling test (ICT; ie, step protocol at 80 W + 40 W/3 min) and an upwind sailing test (UST). During both, heart rate (HR), oxygen uptake (VO2), ventilation (VE), respiratory-exchange ratio, and rating of perceived exertion were measured. During UST, also the difference between the required and produced hiking moment (HM) was calculated as error score (ES). HR, VO2, and VE were calculated relative to their peak values determined during ICT. After UST, the subjects were questioned about their opinion on the resemblance between this UST and real-time upwind sailing.Results:An average HM of 89.0% ± 2.2% HMmax and an average ES of 4.1% ± 1.8% HMmax were found. Mean HR, VO2, and VE were, respectively, 80% ± 4% HRpeak, 39.5% ± 4.5% VO2peak, and 30.3% ± 3.7% VEpeak. Both HM and cardiorespiratory values appear to be largely comparable to literature reports during on-water upwind sailing. Moreover, the subjects gave the upwind sailing ergometer a positive resemblance score.Conclusions:Results suggest that this ergometer accurately simulates on-water upwind sailing exercise. As such, this ergometer could be a great help in performance diagnostics and training follow-up.

The results of research investigating differences in matrix completion abilities between low-SES and middle-SES children have been inconsistent. This study provided a framework in which several unresolved issues could be examined. Item type, order of presentation, training modes, and developmental level were varied in two SES groups in an attempt to clarify previous research findings. The subjects were 288 individually tested children. SES level was determined by the Hollingshead and Redlich (1958) scale while developmental level was represented by first, third, and fifth grade levels. Training consisted of maximal prompt, correctness-of-response feedback, and a no-training-control condition. Subject responded to double classification and enclosure matrix completion item types until a criterion performance was obtained, and were then shown 11 transfer items of each type. The results revealed significant SES, grade, and training main effects. Generally, middle-SES and older subjects were able to learn more efficiently and transfer more effectively than their counterparts. SES and training interacted with item type and order of presentation which indicated differential facilitative effects across SES levels. A major finding was the absence of a significant SES X grade interaction. This result supports a developmental lag as opposed to Level I Level II interpretation.

Myofibril Atpase

Diabetes is characterized by depressed cardiac functional properties attributed to Ca2+-activated ATPase activity. In contrast, endurance swimming enhances the cardiac functional properties and Ca2+-activated myofibril ATPase. Thus, the purpose of this study was to observe if the changes associated with experimental diabetes can be ameliorated with training. Diabetes was induced with a single i.v. injection of streptozotocin (60 mg/kg). Blood and urine glucose concentrations were 802 ± 44 and 6965 ± 617 mg/dL, respectively. The training control and training diabetic animals were made to swim (±2% body weight) 4 days/week for 8 weeks. Cardiac myofibril, at 10 μM free Ca2+ concentration was reduced by 54% in the sedentary diabetics compared with sedentary control animals (p < 0.05). Swim training enhanced the Ca2+-activated myofibril ATPase activities for the normal animals. The diabetic animals, which swam for 8 weeks, had further reduced their Ca2+-activated myofibril ATPase activity when compared with sedentary diabetics (p < 0.05). Similarly, the Mg2+-stimulated myofibril ATPase activity was depressed by 31% in diabetics following endurance swimming. It is concluded that the depressed Ca2+-activated myofibril ATPase activity of diabetic hearts is not reversible with endurance swimming.

Review Current

Objective: The purpose of this study was to review current knowledge on exercise physiology and sports training that can be applied to develop training programs for Mixed Martial Arts. Methods: A non-systematic literature review was conducted to search for articles related to history, physiology and training of Mixed Martial Arts and other Martial Arts such as Judo, Wrestling, Jiu-Jitsu, and Karate. A review on aerobic, anaerobic, strength and power training was also conducted and directly related to Mixed Martial Arts training. Results: There is scarce scientific information about training methods and physiological responses to specific efforts in Mixed Martial Arts. Many studies were reviewed and meaningful information on physiology and training were summarized for application in Mixed Martial Arts. Conclusion: The present study provides a review on important physiology and training aspects for successful preparation of Mixed Martial Arts athletes.

And Training

We investigated perceptual learning in 85 healthy adults with stereoscopic information contained in dynamic random dot stimuli or with vernier targets. Stimuli were flashed simultaneously at 8 locations at an eccentricity of 1.15° or 2.3°, and subjects had to detect a target in an “8 Alternative Forced Choice” task. For training at a given eccentricity stimuli at the other eccentricity served as a “no training” control. Viewing of visual targets for about 20 minutes resulted in a significant increase of discrimination performance only for the trained stimuli (significant interaction between training and time). Thus, learning is position specific: improved performance can be demonstrated only when test and training stimuli are presented to the same retinal areas. In combination with our earlier electrophysiological results, this study illustrates how perceptual training induces stimulus and visual field specific neural plasticity in adults.
