Acute Effects Of Light Exercise On Subjectively Experienced Well-Being: Benefits In Only Three Minutes, Attila Szabo, Zoltan Gaspar, Julia Abraham

Baltic Journal of Health and Physical Activity

Background: In the context of sedentary lifestyle as a major contemporary health issue, this study examined how an ultra brief exercise bout affects perceived subjective well-being. Material/Methods: Two studies were conducted. In the first study, young participants performed light exercises for 3-minutes. The second study replicated the first, but a sitting-quietly control group was also included to account for possible habituation or order effects. On a single item 10-point Likert scale, conceptualized as core affect, participants rated their well-being immediately before and after the exercise bouts and rest, respectively. Results: In both studies the exercise triggered statistically significant (p < .001) improvement in the perceived well-being (effect sizes (d) = .62 in Study I, and d = .75 in Study II), while no statistically significant change was noted in the control group. Conclusions: These findings are the first ever in the scholastic literature to demonstrate that only 3 minutes of light exercises could trigger subjective experience of improved well-being. The practical implication of these findings is that an instant boost in subjective feeling states can be achieved through very short, light, and undemanding exercises that could be repeated several times a day in different life settings.

Blood K+ Concentration Balance After Prolonged Submaximal Exercise – The Role Of Both Uptake And Excretion Processes, Anna Szczesna-Kaczmarek

Baltic Journal of Health and Physical Activity

Background: A contracting muscle is a source of the plasma K+ concentration increase during physical exercise. The flux of K+ from contracting skeletal muscle to blood is related to the frequency of cells action potential. The elevated blood [K+] may result in the heart rate irregularities and interferes with the way nerves send signals. But plasma increased [K+] recovers rapidly to normal if a regulating mechanism takes action. The aim of this study was to evaluate the participation of processes restoring the balance in blood [K+] after prolonged submaximal exercise. Material/Methods: Nineteen healthy, young, physically active men performed the 120-min …

Identifying And Reporting Position-Specific Countermovement Jump Outcome And Phase Characteristics Within Rugby League, John J. Mcmahon, Jason P. Lake, Paul Comfort

Research outputs 2022 to 2026

The countermovement jump (CMJ) has been suggested to be an important test of neuromuscular performance for rugby league (RL) players. Identifying force platform-derived CMJ variables that may be more applicable to RL positions (e.g., forwards and backs) has yet to be fully explored in the scientific literature. The aim of this study was to identify RL position-specific CMJ force-time variables. Specifically, we aimed to compare select forcetime variables from the countermovement (i.e., the combination of unweighting and braking) and propulsion phases of the CMJ between the global forwards and backs positional groups. We also aimed to compare typical (i.e., jump …
