Comparison between six-week exergaming, conventional balance and no exercise training program on older adults’ balance and gait speed

Hashim J.; Campelo A.M.; Doyle-Baker P.K. dkk.

International Journal of Computer Science in Sport, Vol. 23 No. 1 · 2024 · Inggris · DOAJ Scopus

We evaluated differences between a six-week exergame-training and a conventional balance training program on the balance and gait speed of older adults’ (>65 years). Forty-two healthy participants were recruited from independent living and community centers and randomized to one of three groups…

Crystal structure and Hirshfeld surface analysis of (E)-N-(4-propyl­oxybenzyl­idene)benzo[d]thia­zol-2-amine

Sheakh Mohamad, Ropak A.; Hamad, Wali M.; Aziz, Hashim J. dkk.

Acta Crystallogr E Crystallogr Commun · 2020 · Inggris · PubMed Central

The title compound, C(17)H(16)N(2)OS, was synthesized by a condensation reaction between 2-amino benzo­thia­zole and 4-N-propoxybenzaldehyde. The benzo[d]thia­zole ring system is nearly planar (r.m.s. deviation 0.0088 Å) and makes a dihedral angle of 3.804 (12)° with the phenyl ring. The…
