Abstract: By recognizing the sequential body configuration and time shifts, it is possible to calculate the dynamic moment of inertia. Body, arm, and leg models were proposed in which possible configurations and influential mass distribution sizes were studied. Described is the choice of optimal models for modeling dynamic moments of inertia which are represented as the best approximation for the dynamic moment of inertia in a dynamic sense. Dynamic and physiological parameters (aerobic, aerobic-anaerobic and anaerobic stimuli) are load indexes based on the geometric progression of the metabolic processes (aerobic - index 3, aerobic-anaerobic – index 6 and anaerobic – index 12). For this purpose, the QBASIC program was used to calculate the weight gain for individual segments according to load indexes (index – 3, 6 or 12). A weight gain calculation program for individual segments according to load indexes of male and female bodies was used to calculate the mass, volume and thickness of silicone with and without the addition of lead balls or lead dust. The training process suit represents a three-layer suit where the suit layers are as follows: the first layer (Lycra) which adheres directly to the skin and which must have an elasticity factor that will satisfy the required flexibility and moisture absorption; the second layer (Silicone) the weight of which is proportionately distributed so that the weight of each segment of the second layer corresponding to each individual body segment is equal to the weight gain for that particular body segment; the third layer (Lycra) which is an outer layer and which is watertight but at the same time passes moisture outwards and is elastic. On this basis, a three-layer suit was made with proportionally distributed loads per individual body segments, which ensures proportional load of the segments and the whole body. Thus applied stimuli provide an even impact on the development of the musculoskeletal nervous system in the direction of the development of motor potentials at a high correlation level in the coordination of body motion in the chosen activity. Application, testing and measurement of the suit performance in certain sport movements (walking, running, pedaling, rowing, volleyball and basketball) were carried out using the POLAR measuring instrument and heart beat frequencies depending on intensity of the load were obtained. Based on the information obtained, the Training Process Suit can be used for sports training, recreational activities and for medical purposes when carrying out physical therapy.

Abstract: High-intensity interval training (HIIT) markedly activates muscle anaerobic glycolysis and increases blood lactate. As the liver is a major organ for lactate clearance from the bloodstream, it might improve gluconeogenesis from lactate (NEO-lac) after a period of resistance HIIT. NEO-lac was evaluated by in situ liver perfusion in mice subjected to a resistance HIIT for 4 (T4) or 8 (T8) weeks, or not trained (T0). Perfusion was carried out immediately after an incremental exercise session to test the acute NEO-lac. Muscle strength (expressed as relative maximum load) and blood lactate were higher in T4 than in T0, but NEO-lac did not differ, possibly because of energy discharge of the liver and substrate overload. After 8 weeks of HIIT (T8), both muscle strength and liver NEO-lac increased, but blood lactate did not. The resistance HIIT for 8 weeks modulated liver gluconeogenic efficiency and capacity, which are important mechanisms for the improved clearance of blood lactate.

Abstract: In Taiwan, the government interestingly requires primary school students to be able to swim 15 meters. By analyzing the drowning statics between Y2014 and Y2017, the program seems to be working. Understanding American Academy of Pediatrics’ recommendation that most children age 4 and older should learn to swim, the purpose of this paper was to understand Taiwanese parents’ views and opinions on kindergarteners’ swimming lessons. By looking into parents’ background and experiences, it is possible to construct a picture on the status of children’s swimming before entering primary school and identify opportunities to do better. The target subjects were parents of kindergarteners whom were between 4 and 6 years old. Returned questionnaires were analyzed statistically, and from this the conclusions were drawn. Recommendations were made through literature reviews, online researches and findings. The summary provided below was based on the statistical analysis: (1) Fathers ranked themselves higher on swimming ability than mothers did. (2) More than half of the parents went to swimming once every few months. They liked to go swimming with other family members. (3) Nearly 1/3 of parents thought the best time to learn swimming was between ages of 4 and 5. (4) However, less than 1/4 of parents had helped their child/children signed up for the swimming lessons. Learning to swim before primary school was not popular in Taiwan. (5) Being afraid of water, not interested in swimming, too troublesome were the constraints which affected parents’ willingness to sign up swimming lessons for their child/children. (6) Easy to register, cleanliness of the pool, close proximity to home, and kid-friendly pools were the key factors leading to satisfaction. (7) Parents across all income level believed the cost of the swimming lessons were reasonable. (8) Both fathers and mothers shared similar views on how the classes should be conducted. More mothers preferred having certified professionals and having water safety included in the lesson.

Abstract: Athletic performance depends on athletic ability as well as body build. Training is a crucial factor for success. For this training, knowledge of initial levels of fitness as well as body build both is important. Physical training alters body build as well as internal physiological system in athletes. The main purpose of this study is to provide categorization of different lung capacities in trained athletes according to their body build. One hundred forty eight trained male athletes participated whose age was between 10-20 years. They were classified into endomorph, mesomorph and ectomorph. Different lung capacities were measured. One way ANOVA was done to compare three body types. Scheffe’s post hoc test was also performed. Lung variables such as SVC, FVC, FEV1 and PEFR are found to be significantly different among endomorph, mesomorph and ectomorph. SVC and FEV1 was found to be significantly highest in ectomorph and lowest in endomorphs. It might be due to least amount of abdominal fat and stature. FVC and PEFR were found to be highest in mesomorph and lowest in endomorphs. Mesomorphs possess maximum muscle mass and so highest FVC. Significant differences in SVC, FVC, FEV1 and PEFR indicates somatotypes have definite role in different lung capacities among trained athletes. It reflects that somatotypes should also be considered during assessments of different lung capacities in trained athletes. Endomorphs have poorest lung capacities. It might be due to more fat accumulation in their body.
