简要总结
Clinical Trial, repeated-measures design, pilot study.
81 young adults, male (30) and female (51) underwent research protocol.
The aim of the research will be to assess the impact of long-term dance training on psychomotor performance, balance, body posture control and the level of neurotrophic factors in the blood in young adults.
People qualified for the study were divided into 3 groups depending on their dance experience:
- KT young adults who do not exercise - cosmetology and physiotherapy students who do not practice any sports;
- PT young adults - students joining the "Podlasie" Song and Dance Ensemble - beginners;
- DT young adults trained from the "Podlasie" team with approximately 2-3 years of experience.
The DT group consisted 32 people (13 males and 19 females). In the beginners (PT) group were 25 people(6 males and 19 females) and 28(11 males and 17 females)were in KT group. DT and KT group were test one time (at the beginning) but the PT group was test 3 times ( at the beginning, 6 and 12 months later).
All groups have been subjected to comprehensive tests like anthropometric data, assessment of muscle strength, testing the biomechanical properties of the muscles of the lower and upper limbs and the shoulder girdle, testing postural stability in static and dynamic conditions, assessment of psychomotor skills, manual dexterity/ambidextrous and cognitive functions.
详细描述
I. The specific objectives were to investigate whether the dance training effect on:
- Body composition
- myometric variables (stiffness, flexibility and tension) of the muscle (trapezius upper part, quadriceps femoris, gastrocnemius muscle, patellar ligament proper)
- concentration of selected biochemical factors (testosterone, brain-derived neurotrophic factor (BDNF)
- muscle strength (flex and straighten the knee joint muscles)
- postural stability ( dynamic and static conditions)
- psychomotor skills (Simple reaction, Complex reaction, Eye-hand coordination, Spatial orientation)
- manual dexterity/ambidextrous (Test Purdue Pegboard)
- cognitive functions (TrailMaking Test (TMT) Parts A & B i STROOP 5.1 (ST))
II. Hypothese Dance as a form of long-term training improves psychomotor performance, balance and body posture control, as well as the level of neurotrophic factors in the blood in young adults.
III. Research Questions/Problems How will dance as a form of long-term training affect the psychomotor performance, balance and posture control of young adults? How can dancing as a form of long-term training change the properties (stiffness, flexibility, tension) of muscles at rest and the strength of the muscles of the lower and upper limbs and the shoulder girdle in young adults? How does dancing as a form of long-term training affect the level of neurotrophic factors and androgen hormones in the blood in young adults? Is there a correlation between the level of BDNF and testosterone in the blood and psychomotor performance, balance, body posture control, properties (stiffness, elasticity, tension) and strength of selected muscles in young adults after a dance training process? Does a 12-month dance training process cause similar changes in psychomotor efficiency, balance and body posture control as a 6-month training process in young adults?
IV. The course of the research Before and during the intervention cycle, the dancers were subjected to biomechanical and biochemical tests. Fasting blood was collected on the day of the examination to determine biochemical parameters. Before starting the study, patients completed a research consent form and an abbreviated version of the Minnesota Physical Activity Test (IPQ). During each cycle of tests, myometric measurements of muscle tension, stiffness and elasticity were performed using the Myoton Pro 3 device (Tallinn, Estonia), assessment of muscle strength using the Biodex System 4-ORO, postural stability in static and dynamic conditions using the Accusway Plus AMTI posturographic plate, assessment of psychomotor skills using a computer program, assessment of two-handed manual dexterity (Purdue Pegboard Test) and cognitive functions (TrailMaking Tesr (TMT) Parts A & B and STROOP 5.1 (ST). The research was conducted in 3 stages: at the beginning, after 6 months and after 12 months after introducing dance training.

结局指标
主要结局
Muscle Stiffness
时间窗: Myometric measurements were performed once in the DT and KT groups. However, in the PT group, the study was carried out 3 times, at the beginning, after 6 months and 12 months after the start of dance training
S (stiffness) - is calculated from the formula S-MYO = amax. mprobe / \^ l, where amax is the maximum acceleration of the striking measuring tip \[kg\], a \^ l is the maximum distance the stylus has moved \[m\]. This parameter is expressed in \[N / m\] and determines the force generated by the measuring tip of the myometer needed to deform the tested tissue to a specific depth
Muscle Elasticity
时间窗: Myometric measurements were performed once in the DT and KT groups. However, in the PT group, the study was carried out 3 times, at the beginning, after 6 months and 12 months after the start of dance training
D (decrement) - free decrease of vibration calculated from the logarithm
Blood parameters
时间窗: [Time Frame: Peripheral blood from the antecubital vein was collected on an empty stomach between 6:00 a.m. and 9:00 a.m. before each examination (at baseline, 6 months and 12 months after the start of the intervention)]
The concentration of androgen factors, testosterone and BNDF (brain-derived neurotrophic factor) was determined using the immunochemical ELISA method in accordance with the kit manufacturer\'s instructions (R\&D systems, London UK).
Muscle Tension
时间窗: Myometric measurements were performed once in the DT and KT groups. However, in the PT group, the study was carried out 3 times, at the beginning, after 6 months and 12 months after the start of dance training
F (frequency) - it determines the muscle tension and is calculated as the maximum frequency from the power of the accelerometric signal spectrum and is expressed as in hertz \[Hz\].

- Relative moment of the maximum force of the muscles that extend and bend the knee joint (maximum moment of the muscles that extend (Mpk) and flexing (Mzk) knee joint is determined by the body weight of the examined person(Muscle strength was performed once in the DT and KT groups. However, in the PT group, the study was carried out 3 times, at the beginning, after 6 months and 12 months after the start of dance training.)
- Dynamic and static postural stability(Balance was performed once in the DT and KT groups. However, in the PT group, the study was carried out 3 times, at the beginning, after 6 months and 12 months after the start of dance training.)
