Abstract

Explosive power is the result of a combination of speed and strength exerted maximally in a quick and short time. Weakness in the explosive power of the leg muscles will cause disturbances in the stability of the body's balance, increasing the risk of falls, slipping and decreasing the athlete's jumping ability and performance. This research aims to determine the effect of depth jump exercise on leg muscle explosive power in basketball players in the city of Malang. This research is a quantitative research with a pre-experimental one group pre test post test approach and sampling using a purposive sampling method with a sample size of forty-five (n=45) in Merjosari Park, Malang City. The data obtained was in the form of lower leg muscle explosive power which was measured using the vertical jump test. This research obtained depth jump exercise results with a significance (p) of 0.000 (p<0.05). This research concludes that there is an influence of Depth Jump Exercise on the explosive power of leg muscles.

Abstract

Insufficient engagement in physical activity is one of the most common and persistent contributors to poor health worldwide. This research was conducted to investigate physical activity perceptions in adolescents with low physical activity. This research predominantly qualitative methodologies to elaborate on perceptions of physical activity, individual preferences, and factors that hinder the experiences of adolescents with low physical activity levels. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) was administered randomly to adolescents aged 18-21 to identify adolescents with low physical activity levels who had less than 1 hour per day or did not meet moderate to vigorous physical activity levels. Semi-structured interviews were conducted with adolescents with low physical activity levels based on IPAQ norm calculations. Interviews were analyzed using thematic analysis. The main themes identified, namely misperceptions about physical activity, perceived ambiguity of social support, and perception of risk to understand the perception of physical activity in adolescents with low physical activity levels.

Abstract

Technology and life today have a big influence, especially on the phenomenon of people’s physical activity and body mass index, plus medical students who have a heavy study load will certainly have an influence on these two things. Low physical activity and uncontrolled body mass index will have a major impact on a person's physical fitness, one of the its components is agility. This study aims to determine the relationship between physical activity level and body mass index on agility. This research is a quantitative research with an observational study with a cross sectional approach on 35 students majoring in medicine at Sebelas Maret University who were selected using random sampling techniques. Physical activity was tested using the Indonesian version of the IPAQ SF questionnaire, BMI was tested by measuring the students' height and weight and agility was tested using the Illinois Agility Run Test. The results showed that most of the medical students fell into the moderate category of physical activity level (18 people) and normal body mass index (16 people) but were not too far from those included in the obese category (15 people), none of the students' agility fell into the category good & excellent and most of them fall into the below average (13 people) and poor (12 people) categories. The results obtained were then calculated using Spearmann correlation analysis showing that the physical activity and agility variables had a significance value of p=0.000 with a correlation coefficient of 0.646. The variables body mass index and agility have a significance value of p=0.227 with a correlation coefficient of 0.210. The relationship between the physical activity variable and agility is significant with a strong correlation, while the body mass index variable and agility has an insignificant relationship
