Aims: This study aimed to investigate the effects of online Vinyasa Yoga (VY) and Taijifit™ (12 weeks) in informal caregivers (≥18 years of age).
Methods: Twenty-nine participants were randomized to two groups: VY (n = 16, 55.87 ± 12.31 years) or Taijifit™ (n = 13, 55.07 ± 12.65 years).
Main outcome measures: Prior to and following the study, assessments were made for muscle strength (1-RM leg press, chest press, and handgrip), muscle endurance (leg press and chest press; maximal number of repetitions performed to fatigue at 80% and 70% baseline 1-RM, respectively), abdominal endurance (maximum number of consecutive curl-ups to fatigue), tasks of functionality (dynamic balance and walking speed), and flexibility (sit and reach).
Results: There was a significant increase over time for muscle strength, muscle endurance, tasks of functionality, and flexibility (P = 0.001). The VY group experienced a greater improvement in chest press endurance (VY: pre 19.25 ± 5.90, post 28.06 ± 7.60 reps; Taijifit™ pre 15.69 ± 4.49, post 21.07 ± 5.85 reps; P = 0.019) and abdominal endurance (VY: pre 37.12 ± 31.26, post 68.43 ± 55.07 reps; Taijifit™ pre 19.23 ± 19.00, post 32.07 ± 20.87 reps; P = 0.034) compared to the Taijifit™ group.
Conclusions: VY and Taijifit™ are effective for improving muscle strength and endurance, tasks of functionality, and flexibility in informal caregivers. VY led to greater gains in chest press endurance and abdominal curl-ups.
