This study aims to find out: (1) The differences of effects between recovery of contrast bath and pre neuromuscular facilitation methods of post-anaerobic interval training to lactic acid levels, (2) The differences in lactic acid levels between high VO2max and low VO2max, and (3) The effects on the interactions between recovery method and VO2max to lactic acid levels. The sample was male students of basketball extracurricular SMAN 4 Surakarta collected using purposive random sampling techniques. The data were then analyzed using Two-way ANOVA at a significance level of 5%, as data obtained previously must meet the required tests which include normality test and homogeneity test. It can be concluded that (1) there are differences in the effect of recovery contrast bath method and PNF to the lactic acid levels. Recovery of contrast bath method has an average value of decreased lactic acid levels of 4.58, while stretching pre neuromuscular facilitation (PNF) method is 3.91. The hypothesis test indicates that Ho is rejected in which the value of P <α (0.00> 0.05) with Fobservation of 25.74. (2) There are differences in lactic acid levels between students who have high VO2max and low VO2max. The group with high VO2max has an average value of 4.48, while the group with low VO2max has an average value of 4.01. The hypothesis test of Ho is rejected in which the value of P <α (0.001> 0.05) with Fobservation of 12.74. (3) There is no interaction effects between recovery i An Experimental Study of Recovery of Contrast Bath and Pre Neuromuscular Facilitation Method in Male Students of Basketball Extracurricular SMAN 4 Surakarta, Indonesia method using contrast bath and PNF with VO2max in lactic acid levels, in which the hypothesis test of Ho is accepted with P value > α (0.57> 0.05) with Fobservation of 0.31.

You will notice a reference throughout the electronic version of Physiology of Sport and Exercise, Fifth Edition, to a web study guide (WSG). This resource is available to supplement your e-book. The study guide offers learning activities that complement each chapter in the e-book, and allows students to practice, review, and develop their understanding of chapter concepts. Students can also use the guide's dynamic and interactive learning activities to expand learning beyond a typical lab situation. Activity feedback guides students in finding the correct information. Online chapter quizzes test students' knowledge of the material. Key concepts are reinforced as students conduct self-made experiments and record their own physiological responses to exercise. In addition, the study guide offers access links to scientific and professional journals as well as information on organizations and careers. We are certain you will enjoy this unique online learning experience! Follow these steps to purchase access to the web study guide:

Objective: To compare the effects of Intermittent Pneumatic Compression (IPC) vs. Neuromuscular Electrical Stimulation (NMES) on recovery following anaerobic exercise. Design: Three-arm comparative pretest-posttest experimental design Setting: University Sports complex and Physiotherapy Clinic. Participants: Twenty-four male collegiate basketball players aged 18-25 yrs (mean± SD 20.4±1.8 yrs) Interventions: Participants were randomly assigned into one of the 3 groups; IPC group (n=8), NMES group (n=8) or control group (n=8). Each group performed a repeated sprint test (RAST) following which, the subjects received IPC, NMES or no intervention as a recovery mode, for 20 minutes. Main outcome measures: Blood lactate recorded prior to and at 5, 15 and 25 min following the RAST. Following recovery, subjects performed another bout of RAST to assess for peak power, mean power, and fatigue index, as parameters of anaerobic performance. Results: There was a significant difference in the clearance of blood lactate between three groups (p=0.006*), with NMES group showing greatest drop. The performance decrements in the second bout of RAST were significantly less for the NMES group as compared to control (p<0.05). Conclusion: NMES was more effective than IPC or passive rest, in clearing blood lactate and minimizing performance decrements following an anaerobic exercise bout.

— Sport massage has the purpose of fostering physical conditions, and avoids things that can harm and alleviate suffering as minimize as possible due to sports injuries (Sulistyorini, dkk 2013:12). Sport massage has the effect of relieving stress, improving tissue elasticity, and eliminating the buildup of lactic acid. In the general population of Indonesia, Sport massage is considered as the most powerful means for stimulating the decrease of lactic acid inside the muscle. Sport massage with Swedish techniques has major applications in the form of Eflleurage, Petrissage, Vibration, Tapotement, Friction, Shaking in accordance with anatomical of the athlete's body. The type of research used in this study is quantitative research with experimental method that is quasi experiment. Experimental method is a way to express the relationship between two or more variables to understand the influence of a variable on other variables. Based on these methods, the design research used nonequivalent control group design. In the design of this study, the experimental group and the control group were not chosen randomly, thus the subject division in this study using ordinal pairing technique. So from the design can be known correctly the difference from the treatment result given. Author is using E-Views 5 software to test the correlation between the dependent variable and the independent variable. In lowering the levels of lactic acid and pulse after exercise activities need to be considered. It is expected that trainers and implementers of sports activities can make Sport and Thai Massage as a reference in an effort to reduce lactic acid levels and pulse after doing heavy physical activity.

Purpose: The aim of this study was to investigate the combined effect of Creatine (Cr) and sodium bicarbonate (SB) supplementation on blood lactate and anaerobic power during two bouts of repeated vertical jump test in taekwondo players. Methods: Sixteen young male taekwondo players were matched in two treatments (Cr+SB, n=8 and placebo (P), n=8) according to weight, Vo 2 max and anaerobic power in double-blinded procedure. Both treatments consisted of placebo (20 gr maltodextrine per day) or Cr supplementation (20 gr Cr per day) in a period of six days. In the morning of the seventh day and after the blood taking, there was P or SB supplementation (0.065 gr per kg body weight), an hour before two repeated vertical jump tests that were performed in 30 seconds with an hour of active recovery between sets. Blood samples were taken in two phases, each phase in three steps after an overnight fast. The data was analyzed via repeated measures, post hoc least significant difference (LSD) a...
