There were three groups of participants, with 10 male amateurs each: RUN + WS, WS, and control. The research was performed in the middle of the winter swimming season of 2020\/2021. This time period was chosen in consideration of the respondents\u2019 adaptation to winter conditions. The study involved only 10 male amateurs in each study group owing to COVID-19 pandemic restrictions, which confined people to their homes. In the RUN + WS group compared with the WS group, significant decreases in the mean corpuscular hemoglobin concentration (within standard limits) (p = 0.04) and platelet distribution width (p = 0.006) were observed, with a significant increase in the red blood cell distribution width (p = 0.008) (within standard limits). The renal function, as expressed by the estimated glomerular filtration rate, was higher in the RUN + WS group (p = 0.02) (within standard limits) compared with the WS group, and the uric acid concentration was reduced (p = 0.01). In the RUN + WS group compared with the control group, significant decreases in the leukocyte count (p = 0.02) (within standard limits), monocyte count (p = 0.04) (within standard limits), and platelet distribution width (p = 0.005) were reported. The remaining indicators presented a p-value &gt; 0.05. The two investigated forms of physical activity had no negative effect on blood morphological or biochemical indicators in male amateurs during the winter swimming midseason.<\/jats:p>","DOI":"10.3390\/life14040474","type":"journal-article","created":{"date-parts":[[2024,4,4]],"date-time":"2024-04-04T06:57:34Z","timestamp":1712213854000},"page":"474","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Blood Morphological and Biochemical Indicator Characteristics in Men Performing Different Physical Activities in the Cold\u2014A Preliminary Report"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5420-4779","authenticated-orcid":false,"given":"Aneta","family":"Teleg\u0142\u00f3w","sequence":"first","affiliation":[{"name":"Department of Health Promotion, Institute of Basic Sciences, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wac\u0142aw","family":"Mirek","sequence":"additional","affiliation":[{"name":"Institute of Sports Science, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9688-4706","authenticated-orcid":false,"given":"Bart\u0142omiej","family":"Ptaszek","sequence":"additional","affiliation":[{"name":"Institute of Applied Sciences, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9505-4081","authenticated-orcid":false,"given":"Marcin","family":"Maciejczyk","sequence":"additional","affiliation":[{"name":"Department of Physiology and Biochemistry, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dorota","family":"Godawska","sequence":"additional","affiliation":[{"name":"Civilization Diseases Treatment Centre, Specialist Clinics Complex, 31-559 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jakub","family":"Marchewka","sequence":"additional","affiliation":[{"name":"Institute of Clinical Rehabilitation, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"302","DOI":"10.4103\/0974-2700.66570","article-title":"Post exercise ice water immersion: Is it a form of active recovery?","volume":"3","author":"Lateef","year":"2010","journal-title":"J.
