Introduction. Currently, there is a need to improve approaches to the use of physical activity in men of working age, focusing on the indicators of the functional system of their body.
The purpose of the study is to trace the dynamics of functional characteristics of mature men engaged in kettlebell lifting on a regular basis.
Methodology and organization of the study. 33 clinically healthy men of the second mature age (mean age 48.4±1.2 years) who had an initially low level of physical fitness were examined. They were divided into two comparable groups: experimental and control. Men of the experimental group (n=18) started rational kettlebell lifting exercises controlled by the coach. The control group (15 people) maintained its initial low physical activity. The groups were monitored for five months. Kettlebell lifting in the experimental group was carried out for 45 minutes, four times a week with a gradual controlled increase in the load. Both groups were examined initially and after five months of follow-up. The heart rate, systolic and diastolic pressure levels, indicators in the Genchi and Barbell tests, the volume of vital capacity of the lungs after performing a two-minute run on the spot, total endurance in the running test, the Harvard step test index, the class of aerobic capabilities and general motor activity were recorded by taking into account the number of steps. The results were processed by the Student's t-criterion.
The results of the study and their discussion. Initially, mature men in two groups had modest physical capabilities. The evaluation of the indicators taken into account in the control re-established a tendency to deterioration of the characteristics taken into account.
Five months later, in the experimental group, the heart rate decreased by 20.8%, being 33.6% lower than the control. In the experimental group, systolic pressure decreased by 9.8% and diastolic pressure by 11.7%, yielding to that in the control by 16.1% and 17.5%, respectively.
By the end of the observation in the experimental group, the level of motor activity increased by 47.2%, prevailing over the control level by 58.4%. The indicators of the Gencha sample at the end of the observation in kettlebell lifting improved by 22.6%, exceeding the control by 32.4%. The Bar sample index had similar changes. It improved by 20.5%, being 30.2% higher than the control. The
level of aerobic ability in those engaged in kettlebell lifting increased by 18.2% and exceeded the control by 17.1%. This was based on a 32.7% increase in the volume of vital capacity of the lungs in the trainees, which began to exceed that in the control by 33.8%.
The Harvard test index for individuals in the experimental group increased by 22.6%, which indicated the transition of the trainees from the status of a low level of physical capabilities to the status of an average level of physical fitness.
Conclusion. Kettlebell lifting activates the functional capabilities of the cardiorespiratory system in mature men. This situation provides them with an increase in the level of development of the musculoskeletal system, activates internal organs and provides general recovery.
