METHODS: This was a cross-sectional study that used data collected through a self-administered questionnaire. A combination of partial least squares-structural equation modeling (PLS-SEM) and necessary condition analysis (NCA) technique was used to analyze and discuss the 308 valid questionnaires, test the hypotheses, and conduct an in-depth analysis.
RESULTS: The results showed that PC, perceived trust, and performance expectancy were significantly related to the intention to use MVM. Effort expectancy was a non-significant predictor of intention to use MVM. Social influence was a significant negative predictor of the intention to use MVM. More importantly, performance expectancy was found to be a necessary factor for MVM intention, providing new marketing ideas for MVM owners. Age had a significant moderating effect on the facilitating conditions and intention to use vending machines. The relatively young population is more conscious of the facilitating conditions.
CONCLUSIONS: The findings of this study are of considerable importance as a guide for the main user group of vending machines. The combined analysis and discussion of PLS-SEM and NCA provide a sound theoretical basis for the practical implications of this study. In the future, we will attempt to use this technique in other areas of study. In terms of theoretical implications, this study provides technical references for future research.
METHOD: This study used guidelines for the systematic review and meta-analysis of PRISMA, Web of Science, EBSCOhost (SPORTDiscus), PubMed, Scopus, and Google Scholar to collect original references in electronic databases. The PICOS method was selected for the inclusion criteria. The physiotherapy evidence database (PEDro) scale was used to assess the scoring for articles' risk range of bias. The scoring of 20 studies ranges from 4-8, and study quality is moderate to high.
RESULTS: Out of 285 identified studies, only 20 articles fulfilled all the eligibility criteria after screening. IRT could significantly improve reciprocal, static, and dynamic balance ability among judo athletes, basketball players, weightlifters, archery athletes, soccer players, rhythmic gymnasts, badminton players, track and field athletes, handball players, volleyball players, and gymnasts using unstable surfaces or environments (i.e., BOSU, Swiss, Wobble boards, Suspension trainer, Sissel pillows, Inflated disc and foam surface, Airex balance pad, Togu power ball, Thera-Band, Elastic band strap, Sand surface and so on).
CONCLUSION: The finding suggests that different types of IRT benefit athletes as this training method can effectively enhance reciprocal, static, and dynamic balance ability in athletes. Therefore, this review suggests that IRT should be considered in athletes' daily training routines for the physical fitness of reciprocal, static, and dynamic balance ability.
METHOD: This study used guidelines for the systematic review and meta-analysis of PRISMA, Web of Science, EBSCOhost (SPORTDiscus), PubMed, Scopus, CNKI, and Google Scholar to collect original references in electronic databases. The Population, Intervention, Comparison, Outcome, and Study Design (PICOS) method was selected for the inclusion criteria. The physiotherapy evidence database (PEDro) scale was used to assess the scoring for articles' risk of bias. The scoring of 12 studies ranges from 5-7 (out of 11 points), and study quality is moderate to high.
RESULTS: Out of 285 identified studies, only 12 articles fulfilled all the eligibility criteria after screening. ICT could significantly improve trunk strength and sprint performance among various athlete populations using unstable surfaces or environments (i.e., BOSU ball, Swiss ball, wobble boards, suspension trainer, Sissel pillows, inflated disc, foam surface, Airex balance pad, Togu power ball, thera-band, elastic band and so on) than TCT using stable surfaces or environments (i.e., floor and bench). In addition, the ICT vs TCT intervention showed a moderate to large effect size (ES = -0.40-1.86; all p < 0.05) in improving trunk muscle strength and sprint performance.
CONCLUSION: The finding suggests that different types of ICT benefit athletes, as this training method can effectively enhance trunk strength and sprint performance in athletes than TCT. Therefore, this study suggests that ICT should be considered in athletes' daily training routines for trunk strength and sprint performance.
