Effects of high intensity intermittent training on lipid profile and blood glucose overweight/obese university students

Subjects Quasi-experimental type study. The population corresponded to 106 students between the ages of 18 and 24 who attended the gym of the María Cano University Foundation, Neiva, during the second period of 2019. The sample was selected in a random probabilistic way using Microsoft Excel and corresponded to 30 students, according to the formula for finite populations. Inclusion and exclusion criteria The students, including were active members at the María Cano gym during 2019, who signed the informed consent and presented a BMI Body Mass Index greater than 25 kg / m2 (overweight). Those students who did not complete all the assessment and training sessions were excluded. Ethics The research follows resolution 008430 and the Declaration of Helsinki. Likewise, the ethics committee of the María Cano university foundation a university in Colombia approved the investigation, through the extraordinary session # 02 of 2019. Initially, each of the research participants was made aware of the purpose, benefits, and risks. In the same way, the participant fills out the informed consent, which was used as support to verify the desire to be part of the research process. Procedures The members of the sample were randomly assigned into two groups of 15 students, thus leaving a control group (continuous training): 15 and an experimental group (high-intensity intermittent training: 15. However, only 14 students received all intervention sessions. It is highlighted those various studies take samples of less than 40 people: 35 people14 16 people15, 32 participants16, 24 participants17, 32 participants18 Each student voluntarily signed the informed consent, thus accepting participation in the research. Instruments Lipid profile: to assess this variable, laboratory blood tests were applied to each of the participants before and after the intervention. The exams were carried out between 6 and 7 in the morning, with a previous fast> 12 h. HDL, LDL, Triglycerides, and VLDL values were analyzed. Glucometry: To measure blood glucose, the Prodigy Auto Code lot # 107120005 brand glucometer with Prestige Suave lancets was used. All participants attended a fast from 8 to 12 hours between 6:30 and 7:30 a.m. Data analysis The data were entered into a matrix in Microsoft Excel and then exported to the statistical program (SPSS) version 24 where frequencies of all the variables for each group were generated. The database was stored in Mendeley Data. Likewise, was applied the Shapiro-W
