Motor Control Section 3: Motor control aspects of resistance training Unit 6c: Expert views on resistance training involved in tennis and table tennis, then the two tasks will interfere one with the other. If different sets of neurons are used, then Roger Federer could become a tennis table champion while maintaining his tennis ranking. Source #6: Functional-task exercise versus resistance strength exercise to improve daily function in older women: a randomized, controlled trial. de Vreede PL, et al. J Am Geriatr Soc. 2005 Jan;53(1):2-10. Functional tasks exercise versus resistance exercise to improve daily function in older women: a feasibility study. de Vreede PL, et al. Arch Phys Med Rehabil. 2004 Dec;85(12):1952-61. Objectives: To determine whether a functional-task exercise program and a resistance exercise program have different effects on the ability of community-living older people to perform daily tasks. Design: A randomized, controlled, single-blind trial. Setting: Community leisure center in Utrecht, the Netherlands. Participants: Ninety-eight healthy women aged 70 and older were randomly assigned to the functional-task exercise program (function group, n=33), a resistance exercise program (resistance group, n=34), or a control group (n=31). Participants attended exercise classes three times a week for 12 weeks. INTERVENTIONS: Exercises were given 3 times weekly for 12 weeks. The functional tasks exercise program aimed to improve daily tasks in the domains first affected in older adults, whereas the resistance exercise program focused on strengthening the muscle groups that are important for functional performance. Measurements: Functional task performance (Assessment of Daily Activity Performance (ADAP)), isometric knee extensor strength (IKES), handgrip strength, isometric elbow flexor strength (IEFS), and leg extension power were measured at baseline, at the end of training (at 3 months), and 6 months after the end of training (at 9 months). Results: The ADAP total score of the function group (mean change 6.8, 95% confidence interval (CI)=5.2-8.4) increased significantly more than that of the resistance group (3.2, 95% CI=1.3-5.0; P=.007) or the control group (0.3, 95% CI=-1.3-1.9; P<.001). Moreover, the ADAP total score of the resistance group did not change significantly compared with that of the control group. In contrast, IKES and IEFS increased significantly in the resistance group (12.5%, 95% CI=3.8-21.3 and 8.6%, 95% CI=3.1-14.1, respectively) compared with the function group (-2.1%, 95% CI=-5.4-1.3; P=.003 and 0.3%, 95% CI=-3.6-4.2; P=.03, respectively) and the control group (-2.7%, 95% CI=-8.6-3.2, P=.003 and 0.6%, 95% CI=-3.4-4.6; P=.04, respectively). Six months after the end of training, the increase in ADAP scores was sustained in the function group (P=.002). Conclusion: Functional-task exercises are more effective than resistance exercises at improving functional task performance in healthy elderly women and may have an important role in helping them maintain an independent lifestyle.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
