To document the characteristics of participants aged 50 years and older in a local government group exercise program (Strong Seniors), to investigate the motivators and barriers to ongoing exercise, and to identify factors associated with more frequent exercise class attendance. Ninety-three participants completed a survey about exercise class attendance, motivators and barriers to participation, and exercise perceptions and self-reported exercise. The authors conducted a mixed-methods study involving both quantitative and qualitative analyses. Personal benefits of exercise and social influences were the most common motivators for regular exercise. Barriers to participation included health problems and lack of time (competing priorities). A higher score on the perceived exercise benefits scale is the only factor associated with a higher frequency of attendance at Strong Seniors classes. Exercise programs for people aged 50 years and older that emphasize associated health benefits and promote social support may be more likely to facilitate long-term attendance.

The aims of the current study were to analyze a kick from 10 m in a futsal context and the parameters of muscular strength using an isokinetic dynamometer in a laboratory environment, performed with the dominant (DL) and nondominant lower limbs (NDL). Seventeen professional elite players participated. Kicking performance was evaluated from the second penalty mark. Next, athletes completed a strength evaluation with an isokinetic dynamometer at speeds of 60°⋅s–1, 180°⋅s–1, and 300°⋅s–1. Significant differences were observed for hip (15.64 ± 3.44; 13.97 ± 2.62), ankle (63.19 ± 8.90; 52.55 ± 8.72), foot (82.31 ± 7.93; 68.41 ± 7.85), and ball (99.74 ± 8.45; 88.31 ± 7.93) speeds (km⋅h–1), and average power at 180°⋅s–1 (325.59 ± 40.47; 315.79 ± 39.49 W), but not for accuracy (1.33 ± 0.57; 1.66 ± 0.77 m) between the DL and NDL, respectively. Few moderate correlations were observed in the DL (r = .54–.64) or NDL (r = .53–.55) between the kinematic variables of kick and muscular strength parameters (P < .05). We conclude that highly trained players present asymmetries in kicking motion; however, the imbalance in muscular strength is very small. We recommend that specific court tests be conducted to reliably characterize kicking performance in futsal. Success in kicking seems to be too variable and complex to be totally predicted only by joints, foot and ball speed, and lower limb muscular strength parameters.
