Protective Role of Aerobic Exercise Against Cisplatin-Induced Nephrotoxicity in Rats
Conclusions: Aerobic exercise may reduce CP-induced nephrotoxicity with a favorable effect on renal function by increasing activation of antioxidant system.,Materials and Methods: Thirty male Wistar rats were randomly divided into four groups. Group I had aerobic exercise on a treadmill one hour per day and five days per week for eight weeks. Then, the exercise protocol was continued for another week, but during this week, the animals also received CP (2.5 mg/kg/day; ip). Group II underwent the same protocol as group I without exercise in the last week during the CP therapy. Groups III and IV were assigned as positive and ...

Regular Football Practice Improves Autonomic Cardiac Function in Male Children
Conclusions: Children engaged with regular football practice presented enhanced physical fitness and autonomic function, by increasing vagal tone at rest.,Results: The anthropometric and body composition characteristics were similar in both groups (P > 0.05). The groups were also similar in time spent daily on moderate-to-vigorous physical activities (FG vs. CG: 114 ± 64 vs. 87 ± 55 minutes; P > 0.05). However, the FG performed better (P < 0.05) in Yo-Yo intermittent endurance test (1394 ± 558 vs. 778 ± 408 m) and 15-m sprint test (3.06 ± 0.17 vs. 3.20 ± 0.23 s). Also, the FG presented enhanced autonomic fun...

Criterion Related Validity of Karate Specific Aerobic Test (KSAT)
Conclusions: The KSAT has not proved to have indirect criterion related validity as no significant correlations have been found between TE’s KSAT and treadmill VO2max. Nevertheless, as correlated to other aerobic fitness variables, KSAT can be considered as an indicator of karate specific endurance. The establishment of the criterion related validity of the KSAT requires further investigation.,Patients and Methods: Cardiorespiratory responses, aerobic performance level through both treadmill laboratory test and YoYo intermittent recovery test level 1 (YoYoIRTL1) as well as time to exhaustion in the KSAT test (TE’KSAT) ...

Effect of Therapeutic Sequence of Hot Pack and Ultrasound on Physiological Response Over Trigger Point of Upper Trapezius
Conclusions: The application of HP and US treatment induces physiological responses (especially, TBF and PPT) on the LMTrP. This finding provides the direction toward the management of MTrPs condition.,Results: The TBF and PPT significantly increased from baseline in both treatment conditions (i.e. HP + US and US + HP), while the HP + US condition showed a trend toward significant difference in VAS and STT in 45°C.,Materials and Methods: Thirty subjects with a latent myofascial trigger point (LMTrP) in both sides of the upper trapezius muscle participated in the study (age 27.33 ± 4.34 years, weight 58.11 ± 7.47 kg, hei...

Five-Kilometers Time Trial: Preliminary Validation of a Short Test for Cycling Performance Evaluation
Conclusions: TT5km is a valid test to rank the aerobic endurance fitness of well-trained cyclists and to differentiate changes on aerobic endurance performance. Coaches can detect performance changes through either absolute (± 17.7 W) or relative power output (± 0.3 W.kg-1), the time to complete the test (± 13.4 s) and the average speed (± 1.0 km.h-1). Furthermore, TT5km performance can also be used to rank the athletes according to their aerobic endurance fitness. (Source: Asian Journal of Sports Medicine)

Effects of a Mask on Breathing Impairment During a Fencing Assault: A Case Series Study
Conclusions: Our study shows that wearing the mask causes increased breathing impairment in fencers, when compared with similar physical activity without the mask.,Results: Before physical exercise, the total nasal airway resistance mean value for AAR was 0.33 ± 0.17 Pa/cm3/s at 150 Pa. After a match with the mask, the mean value was 0.28 ± 0.16 Pa/cm3/s. After normal physical exercises without mask, the mean value was 0.24 ± 0.15 Pa/cm3/s. Using t tests, statistically significant difference between nasal resistance before and after physical activity (P < 0.05) was observed, but no significant difference in nasal res...

Specific Intensity for Peaking: Is Race Pace the Best Option?
Conclusions: A 6 week period of training at either 105% of MAV or 90% of MAV yielded similar performance gains in a 10km race performed at ~90% MAV. Therefore, the physiological impact of HIT training seems to be positive for VO2max but negative for running economy.,Results: Both groups significantly improved their 10 km time (35 minutes 29 seconds ± 1 minutes 41 seconds vs 34 minutes 53 seconds ± 1 minutes 55 seconds, P < 0.01 for HIT; 35 minutes 27 seconds ± 1 minutes 40 seconds vs 34 minutes 53 seconds ± 1 minutes 18 seconds P < 0.01 for RP). VO2max increased after HIT (69 ± 3.6 vs 71.5 ± 4.2 ml.Kg-1.min-1, ...
