Standalone sauna vs exercise followed by sauna on cardiovascular function in non‐naïve sauna users: A comparison of acute effects
2021
Background and aimsSauna bathing and aerobic exercise have each been shown to affect cardiovascular function. However, direct comparisons between standalone sauna bathing and a combination of exercise and sauna on vascular indices remain limited. Therefore, we conducted a cross-over study using matched durations to explore the hemodynamic changes of sauna exposure when compared to a combination of aerobic exercise and sauna exposure.MethodsParticipants (N = 72) with at least one cardiovascular risk factor underwent, on two separate occasions: (a) a 30-minute sauna at 75°C (SAUNA) and (b) the combination of a 15-minute cycling exercise at 75% maximum heart rate followed by 15-minute sauna ex…
Acute effects of short-duration isolated static stretching or combined with dynamic exercises on strength, jump and sprint performance
2013
Summary Objective This study aimed to investigate the acute effects of a short-duration isolated static stretching or combined with dynamic plyometric exercises on the performance of some anaerobic parameters (strength, jumping and sprinting). Methods During three distinct sessions and after a standardized warm-up, 15 participants randomly performed static stretching exercises alone, static stretching combined with plyometric exercises and no stretch. Total stretch duration was 20 seconds long per muscle group (quadriceps, hamstrings and calf muscles). Tests included maximal quadriceps muscle strength, countermovement jumps and 15 m sprints. Results Whatever the condition, maximal strength …
Want to Impact Physical, Technical, and Tactical Performance during Basketball Small-Sided Games in Youth Athletes? Try Differential Learning Beforeh…
2020
This study aimed to analyze the acute effect of small-sided games, based on differential learning, on the physical, technical, and positioning performance of young basketball players. Eight basketball players under 13 (U13) participated in this study. A total of eight sessions involving half-court small-sided games (4 sets ×
Acute Effects of Mechanical Vibration
1986
We know that man possesses a highly developed ability to adjust to different environmental conditions. For this function there are physiological regulatory systems, which release reactions in him for protection against such influences. Thus, receptors for light, smell, taste, temperature, sound, touch, position change, pressure, and tension are at hand which, as parts of the cybernetics system, can release physiologically meaningful protective reactions.
Acute stress and working memory in older people.
2015
Several studies have shown that acute stress affects working memory (WM) in young adults, but the effect in older people is understudied. As observed in other types of memory, older people may be less sensitive to acute effects of stress on WM. We performed two independent studies with healthy older men and women (from 55 to 77 years old) to investigate the effects of acute stress (Trier Social Stress Test; TSST) and cortisol on WM. In study 1 (n = 63), after the TSST women (but not men) improved their performance on Digit Span Forward (a measure of the memory span component of WM) but not on Digit Span Backward (a measure of both memory span and the executive component of WM). Furthermore,…
Untersuchungen �ber eine akute Wirkung von Trijodthyronin auf Refrakt�rzeit und Leitungsgeschwindigkeit des Meerschweinchenvorhofs
1962
Es wird uber die Untersuchung einer akuten Wirkung von T3 in vitro auf die Refraktarperiode und die Leitungsgeschwindigkeit des Meerschweinchenvorhofs berichtet. T3 verkurzte die Refraktarzeit geringfugig (5,2%). Bei vermindertem K-Gehalt der Badlosung oder nach Vorgabe von ACh oder DNP trat die Verkurzung der Refraktarzeit unter T3 wesentlich deutlicher in Erscheinung, und es konnte Flimmern ausgelost werden, obwohl die Substanzen vor der Gabe von T3 vollstandig ausgespult waren. Adrenalin hatte keinen Einflus auf den T3-Effekt. Die Leitungsgeschwindigkeit wurde durch T3 nicht verandert.
Acute effect of induced asymmetrical running technique on foot skin temperature
2020
The aim of the study was to evaluate skin temperature of the soles of the feet before and after a provoked asymmetrical running. Seventeen recreational male runners performed two 15 min running tests in the same session. In the first test, participants performed running without modifying their running technique (control condition). In the second running test, they repeated the same protocol using an ankle weight of 1.5 kg in the non-dominant ankle (asymmetrical condition). Rate of perceive exertion, heart rate and spatio-temporal parameters were measured during the running tests. Skin temperature was measured with an infrared camera before and after each condition. Generally, comparing both…
Understanding the Experiences of Heavy Smokers after Exercise
2015
There is now strong evidence that exercise has an acute effect on the urge to smoke and the accompanying withdrawal symptoms. However, the perceptions by heavy smokers of exercise and its relationship to the urge to smoke have not been well documented. The aim of the present study is to understand the experiences of heavy smokers with regard to exercise and its effect on their urge to smoke. Five physically inactive, heavy smokers are asked to abstain from smoking the night before exercising on a cycle ergometer under two conditions (one at medium and one at vigorous intensity done a week apart). Semi-structured, in-depth interviews are conducted after the second exercise session. Thematic …
Ver�nderungen elektrophysiologischer Me�gr��en des Meerschweinchenherzens bei akuter Trijodthyroninwirkung
1963
Mit intracellularen Mikroelektroden wurden von Vorhof- und Kammermuskulatur von Meerscheinchenherzen Membran- und Aktionspotentiale abgeleitet. Die akute Wirkung von Trijodthyronin (T3 10−6 und 10−5 g/ml) auf diese elektrophysiologischen Mesgrosen wurde untersucht; auserdem wurden Veranderungen der intracellularen K- und Na-Konzentrationen in vitro und in vivo gemessen.
Neuromuscular and mobility responses to a vibration session in hypoxia in multiple sclerosis
2020
AbstractThe aim of this study was to investigate the acute effects of vibration training (WBVT) under hypoxic and normoxic conditions on the voluntary rate of force development (RFD), balance and muscle oxygen saturation (SMO2) in persons with Multiple Sclerosis (MS). 10 participants completed the study (30% males, 44.4±7.7 years, 164.3±8.9 cm, 65.2±11.1 kg, 2.5±1.3 Expanded Disability Status Scale, 24.1±4.0 kg.m−2 BMI). Maximal force, RFD during isometric knee extension, static balance with eyes open and closed and sit-to-stand test were evaluated before and immediately after one session of WBVT (12 60-s bout of vibration; frequency 35 Hz; amplitude 4 mm; 1-min rest intervals) under both n…
