Group recommendations.
In the Hong-kong, middle school students try put into three school groups-bands step one, 2 and you will step three according to their academic achievement. New scaled external and internal research marks of the many college students was in fact ordered. Chances are they were similarly divided into about three college or university groups and you can designated so you can secondary universities, per composed of 1/3rd of the final amount out-of students . Into SES, month-to-month house profits away from HK$ 0–fourteen,999, HK$15,000–29,999 and you will HK$>29,100 denoted the lower-, medium- and higher-income classification, correspondingly. The new average-income category produces the newest average month-to-month home-based home income .
Statistical research
Pearson’s Unit-Moment Relationship was used so you can compute the brand new correlations within services regarding understood PL and you can PA accounts. Several regression research was used to examine the latest organization between the observed PL and you may PA amounts of people players. Detailed statistics of profil blackfling participants’ group pointers, for example sex, degree peak (junior and senior secondary), school ring and SES have been considered on Pearson’s Tool-Minute Correlation to help you calculate the correlation anywhere between thought PL and you may PA account. The latest z-scores within correlations had been calculated to examine if those trials have been notably some other . SPSS variation twenty two getting Window was applied into investigation studies. The fresh new rely on level was put once the 95% (P ? 0.05) to maintain statistical reliability.
Overall performance
The teenagers stated its seen PL typically while the (±dos.2dos), (±dos.11) and you can (±1.90) for the three parts, ‘sense of thinking and you may care about-confidence’, ‘self-expression and you will correspondence having others’ and you may ‘studies and you will understanding’, correspondingly. The mediocre every day PA some time and intensity try 74 minutes in the a taking walks rate, which have 34 moments within a media pace and you can 27 moments at a strenuous pace, which satisfied the principles recommending at least an hour every day off participation in every MVPA (61 minutes). Enough time spent in various PA domains is typically, 47 minutes at school, 17 times home, 66 moments during transportation and you will 48 times throughout the athletics.
Table 1 shows the significant correlations between the perceived PL and PA levels (r = 0.227, p < 0.01) of the Hong Kong adolescents measured by the PPLI and IPAQ-A. Although the correlations are modest, components of perceived PL, intensities of PA levels and three domains (school, transportation, and recreation) of PA were significantly correlated (r = 0.067–0.292, p < 0.01). No significant correlation was found for the home domain.
A multiple linear regression was calculated to predict the PA levels of participants based on their perceived PL attributes. Preliminary analyses were performed to ensure no violations of the assumptions of normality, linearity and multicollinearity. Table 2 shows the significant regression equation (F (3, 1941) = , p < 0.01), with an R 2 of 0.052. The participants predicted PA levels were –5490 + 366.1 (sense of self and self-confidence) + (self-expression and communication with others) + (knowledge and understanding) MET minutes when the attributes of perceived PL were measured on a 5-point Likert Scale. The results showed that sense of self and self-confidence (? = 0.123, p = 0.000), self-expression and communication with others (? = 0.071, p = 0.003) and knowledge and understanding (? = 0.082, p = 0.007) were positively related to PA level. The participants' mean PA levels increased by 366.1, and MET minutes for each attribute score of perceived PL. All attributes of perceived PL were significant predictors of PA level.
The research party following explored elements away from gender, stages height, college band and you can SES in addition to their impact on the partnership between thought PL and you may PA membership, as shown from inside the Table step 3. All of the organizations displayed tall surely correlations ranging from detected PL and you will PA.
