The purpose of this investigation was to assess the acute effects of partial range of motion (pROM) exercises, on the accuracy of soccer penalty kicks on goal. This method limits the joint from moving through the complete length of a motion, creates an occlusion effect, and thus causes the type 1 muscle fibers to work anaerobically. Thirty-six soccer players, with 5-8 years of soccer playing experience, were pretested for accuracy then retested ( rtt = 0.92 ) and divided into random groups from the Associação Banco do Brasil Futebol Clube—Group A, Paraná Futebol Clube—Group P, and Coritiba Futebol Clube—Group C. Groups were composed of 12 people performing full range of motion (fROM) exercises or pROM exercises. Both groups performed 5 sets of back squats at 50% of body weight in sets of 40 seconds with metronome tempo of 56 bpm for an average of 10-12 repetitions per 40-second set. Blood samples were collected post-warm-up, after the 3rd set, and following the 5th set for both groups, within 3–5 minutes of cessation of exercise. Athletes performing fROM exercises showed increased blood lactate from 2.69 ± 0.2 to 4.0 ± 1.2  mmol/L ( p < 0.05 ), and in pROM, blood lactate increased from 2.48 ± 0.42 to 10.29 ± 1.3  mmol/L ( p < 0.001 ). In fROM, accuracy decreased from 42.96 ± 13.39 % to 41.37 ± 17.25 % ( p > 0.1 ), a slight decrease, while in the pROM groups, accuracy decreased from 45.42 ± 14.93 % to 24.53 ± 10.2 % ( p < 0.001 ). The calculations demonstrating average percentages of accuracy are presented in the tables. These findings support that pROM exercises significantly increase blood lactate resulting in a reduction in soccer kick accuracy. This decrease in accuracy directly correlates to the accumulation of lactic acid and hydrogen ions (H+) and demonstrates that pROM strength training should not be utilized prior to a sport-specific session in order to avoid interference with the development of special skills.

Cholinergic urticaria (CholU) is a chronic inducible urticaria, characterised by itchy pinpoint wheals up to 3 mm in diameter, surrounded by a prominent flare, that occur following an exposure to characteristic triggers such as active or passive heating, physical exercise, emotions, hot or spicy foods. Key pathophysiologic mechanisms include immediate hypersensitivity to autologous sweat antigens, functional sweating disorders, impaired acethylcholine metabolism, abnormal skin vascular permeability and disturbed skin innervation. Clinical manifestations of CholU may vary from typical itchy pinpoint urticarial lesions, angioedema to anaphylaxis. Atypical CholU forms include cholinergic pruritus, cholinergic dermographism, cold cholinergic urticaria and persistent cholinergic erythema. The diagnosis of cholinergic urticaria relies on patients history, сlinical manifestations and challenge tests. Treatment options include nonsedating H1 antihistamines in standard or increased doses. The evidence is accumulating for the use of biological treatment with omalizumab in cholinergic urticaria. The prospect of personalized treatment of cholinergic urticaria include autologous sweat desensitization. The main research efforts in ColdU are directed at optimizing diagnostic approaches and developing innovative therapeutic options.

BACKGROUND: Сhronic spontaneous urticaria is a disease characterized by itchy wheals and/or angioedema on the skin over a period of 6 weeks or longer. Сhronic spontaneous urticaria is characterized by a significant disease burden for patients, their families, healthcare system and a society. Some aspects of сhronic spontaneous urticaria burden. Including the disease impact on physical activity and sport engagement, have not been well characterized. AIM: to evaluate the сhronic spontaneous urticaria impact on patients quality of life and physical activity of patients, and to assess the correlation between the level of physical activity and a UCT control/severity. MATERIALS AND METHODS: The study included 31 сhronic spontaneous urticaria patients, who underwent history taking and a survey using international questionnaires: UAS7 (Urticaria Activity Score for 7 days), UCT (Urticaria Control Test), DLQI (Dermatology Life Quality Index) и GPAQ (Global Physical Activity Questionnaire) developed by the World Health Organization (WHO). RESULTS: According to the GPAQ results, the physical activity level below that recommended by WHO was noted in five (16.1%) patients (MET-minutes/week 600). The moderate level of physical activity was reported in 17 (54.8%) patients, and the high level ― 9 (29%). Median sedentary time in сhronic spontaneous urticaria patients was 420 [300480] min/day, that exceeds the WHO recommendations. The DLQI assessment suggests that 16 (51.6%) сhronic spontaneous urticaria patients had difficulties in their sport activities. Four (12.9%) patients had very strong impact of сhronic spontaneous urticaria on their sport activities. Noteworthy, five patients had to stop their regular physical activity because of сhronic spontaneous urticaria severity. Based on the UCT data, uncontrolled сhronic spontaneous urticaria was reported in 23 of 31 (74.2%) patients, who also had a significantly lower quality of life compared to those with a well-controlled disease. CONCLUSIONS: Сhronic spontaneous urticaria may negatively affect patients quality of life, including their physical activity. A sedentary lifestyle (below the WHO recommendations) was noted in 16.1% patients. In further studies, the optimized recommendations for physical activity in сhronic spontaneous urticaria patients should consider their disease control/severity, their fitness level and patients preferences.
