Recommendations for low JEL levels:
1. During the learning process: frequent ventilation of the room and physical activity during breaks aimed at working the main and auxiliary respiratory muscles.
2. Increase time spent in forest-park zones. Reduce or eliminate harmful habits such as smoking, as this leads to a reduction in the synthesis of surfactant on the inner surface of lung alveoli, which prevents their collapse.
3. Include complete proteins and fats in the diet that restore surfactant in lung alveoli.
4. Include daily aerobic physical activity, outdoors for at least 30 minutes. Use types of motor activity that train the respiratory system according to personal choice. Include various breathing exercises.
5. Keeping health diaries to monitor daily routine, training, and body condition.
Hand Muscle Strength
Normally, the average strength of the right hand muscles (for right-handed individuals) is 35—50 kg for men and 25—33 kg for women. The average strength of the left hand muscles is usually 5—10 kg less than that of the right hand.
Any measure of strength is usually closely related to the volume of muscle mass, i.e. body mass. Therefore, when evaluating the results of dynamometry, it is important to consider both the main absolute strength (i.e. the value shown by the dynamometer) and the relative strength, i.e. relative to body mass. Relative strength is expressed as a percentage. To calculate it, the value of the strength of the right hand is multiplied by 100 and divided by the body mass value. Decreased strength can occur due to illness, negative mood, fatigue, disruption of the motor mode, aging, etc.
