Abstract

The purpose of this study was to analyze about (1) the effect of the method massed practice against the speed and accuracy of service, (2) the effect of the method of distributed practice against the speed and accuracy of service and (3) the influence of methods of massed practice and distributed practice against the speed and accuracy of service. This type of research used in this research is quantitative with quasiexperimental methods. The research design uses a non-randomized control group pretest posttest design, and data analysis using Manova. The process of data collection is done by testing the speed of service (dartfish) and test accuracy (Hewitt) during the pretest and posttest. The results of the study as follows: (1) there is a significant influence on the methods of massed practice to increase the speed and accuracy of service (2) there is a significant influence on the method of distributed practice to increase the speed and accuracy of service (3) There is no significant difference influence among methods massed ptactice practice and distributed to the speed and accuracy of service. Conclusions of this research is a method massed practice and distributed practice equally provide significant results but that gives the influence of better is method distributed practice to speed and accuracy of service.

Abstract

The purpose of this research was to analyze the difference between the effectiveness of Thai and Sports massage against the decrease of lactic acid and blood glucose. The research was experimental laboratoris. The results showed the initial data retrieval on lactic acid level in treatment and control group ranged between between 1.30-3.40 mmol/l of lactate. Then on lactic acid level after activities on Sport massage group was 6.01 mmol/l, whereas the thai massage group was 5.72 mmol/l, and control group was 5.18 mmol/l. whereas in lactic acid levels after 5 minutes of physical activity on a group of sport massage namely 8.36 mmol/l , a group of thai massage 7.26 mmol/l, and the control group 5.83 mmol/l. lactic acid levels and then 10 minutes of physical activity on the group after group of sport massage namely 3.81 mmol/l, a group of thai massage 4.11 mmol/l, and the control group 4.62 mmol/l. While on initial data retrieval on the blood glucose levels between 75 91 mg/dL. then in blood glucose levels after activities on a group of sport massage namely 93.50 mg/dL, while the Group of thai massage 96.12 mg/dL, and the control group 88.75 mg/dL. While in blood glucose levels after 5 minutes of physical activity on a group of sport massage i.e. namely 89.75 mg/dL, a group of thai. massage 88.25 mg/dL and a control group of 88 mg/dL. Then blood glucose after 10 minutes of physical activity on the group the Group of sport massage i.e. namely 81.12 mg/dL, a group of thai massage 83.12 mg/dL, and the control group 85.00 mg/dL. Based on the above analysis, it can be concluded that there is a decrease in the levels of blood glucose and lactic acid for each experimental and control groups group after being given the treatment of Thai Massage and Sports Massage.
