The present research is a field study assessing effects of music and light on physical performance and subjective feelings of 28 participants (14 men, 14 women) in fitness classes using indoor cycling. Participants performed four sessions under different conditions of music and light. Analysis showed a sense of pleasure was significantly higher when music was introduced during the exercise. A significant interaction of music and light indicated that participants experienced less sense of tiredness when they trained with music and lights were dimmed. Light alone had no effect on any of the subjective measures. Physiological measurements showed that light and music did not influence amount of energy exerted (heart rate) or energy expended (calories). Apparently, participants do not work harder when music is present; however, they report more pleasure and less tiredness while exercising with music and dimmed light. It is recommended that music and dimmed light might be used during such activities to heighten pleasure and reduce tiredness while emphasizing fitness achieved.

The purpose of this investigation is to present observational data regarding sleep variables in professional Mixed Martial Arts (MMA) athletes. These sleep performance measures were related to physical performance and injury in MMA athletes. Eight professional athletes were placed into a quasi-controlled, multivariable fight-camp environment for a six-week period in preparation for fight competition. Throughout a six-week fight camp environment, athletes were continuously monitored for sleep performance measures (sleep latency, sleep efficiency, onset, and wake variances) via validated wearable sleep monitoring technology. Athletes were tested seven days prior to competition on measures of physical performance (vertical jump, VO2max, heart rate recovery, prowler sled push, and pull-ups). Multiple correlational analyses were utilized to assess relationships between all sleep and physical performance measures. There were significant (P < 0.05) correlations between sleep latency and VO2max, heart rate recovery, prowler sled push, vertical jump, and missed practice sessions. There were also significant (P < 0.05) correlations between average fall asleep time and heart rate recovery. Lastly, there were significant (P < 0.05) correlations between sleep efficiency, heart rate recovery, and missed practice sessions. MMA athletes who exhibited consistency in sleep demonstrated stronger relationships with performance testing during the fight-camp period.

An increase in the prevalence of insulin resistance in the elderly, associated with physiological changes in carbohydrate metabolism during the aging process, is associated with a high risk of cardiovascular accidents and endocrine diseases. This problem requires a solution by healthcare professionals with medication and non-medication. The purpose of the study was to determine the effectiveness of the program of physical therapy by the dynamics of indicators of the cardiovascular system, carbohydrate and lipid metabolism, psychoemotional status of elderly people with frailty and metabolic syndrome. Material and methods. 96 elderly people were examined. The control group consisted of persons without metabolic syndrome and without frailty. The main group 1 consisted of patients with metabolic syndrome and frailty with a low level of therapeutic alliance who did not want to cooperate with a physical therapist and / or actively improve their health on their own. The main group 2 included patients who agreed to undergo a developed program of physical therapy (a high level of therapeutic alliance) using kinesitherapy, massage, nutritional correction, education of the patient and his family, elements of cognitive training and occupational therapy for 1 year. The effectiveness of the program was assessed by the dynamics of systolic and diastolic blood pressure, heart rate, Kvass endurance coefficient, Baevsky's adaptive potential, Robinson's index, physical performance (based on the results of a 6-minute test), carbohydrate parameters (fasting blood glucose and after glucose load) and lipid (concentration of cholesterol, triglycerides, high density lipoproteins) metabolism, the level of depression according to the GDS-15 questionnaire. Results and discussion. In elderly people with frailty and metabolic syndrome, a statistically significant (p <0.05) deterioration in the parameters of the functioning of the cardiovascular system (according to the levels of DBP, heart rate at rest, Kvass endurance coefficient, Baevsky's adaptive potential, Robinson's index), physical performance (according to the results of a 6-minute test - distance, severity of fatigue, shortness of breath, cardialgia), biochemical parameters (fasting hyperglycemia, impaired glucose tolerance, atherogenic dyslipidemia), psycho-emotional state (depression) from their peers. The use of physical therapy tools led to a statistically significant improvement (p <0.05) of all the studied parameters of the functioning of the cardiovascular system, biochemical parameters in elderly people with metabolic syndrome and frailty, an increase in their physical performance, and an improvement in psycho-emotional status. A low level of therapeutic / rehabilitative alliance led to unsatisfactory fulfillment or non-fulfillment of the recommendations provided by patients and is associated with a lack of improvement in the state of the cardiovascular system, physical performance, age-associated depression. Conclusion. It is advisable to include physical therapy means in the rehabilitation programs for elderly patients with comorbid pathology like frailty and metabolic syndrome for the prevention of cardiovascular accidents

The purpose of this study was to determine the effect of the musical tempo on heart rate (HR), rating of perceived exertion (RPE), and distance run (DR) during a treadmill aerobic test in young male and female adults. Participants ran on the treadmill listening to music at 140 beats per minute (bpm; M140), 120 bpm (M120), or without music (NM). No significant sex differences were found on HR (M140 = 172.6 ± 12.7, M120 = 171.9 ± 11.1, NM = 170.1 ± 12.2 bpm, p = .312), RPE (M140 = 7.5 ± 1.4, M120 = 7.6 ± 1.3, NM = 7.6 ± 1.2, p = .931), or DR (M140 = 4,791.4 ± 2,681.1, M120 = 4,900.0 ± 2,916.9, NM = 4,356.1 ± 2,571.2 m, p = .715). Differences were found in the effect of tempo on HR between condition M140 and NM (172.6 ± 12.7 vs. 170.1 ± 12.2 bpm, p = .044, η2 = 0.32). In conclusion, musical tempo does not affect performance, physiological, or perceptual variables in young adults exercising on a treadmill at a constant speed.

Abstract: The objective of this work was to evaluate the effects of equine infectious anemia (EIA) on the physical performance of equines from the Brazilian Pantanal region. A total of 16 males were evaluated, divided into two groups: 8 seronegative (G1) and 8 seropositive (G2) for EIA. Two graded exercise tests were carried out before (T1) and after (T2) 42 days of training. Heart rate, lactate concentration, distance covered, and hematocrit level were recorded. In both tests, G1 covered a greater distance. In T2, G2 had lower hematocrit levels and lower speeds reached at different lactate concentrations and heart rates. The athletic performance of the evaluated equines is affected by equine infectious anemia.
